This is another entry in the social media compilation series, focused on grafting work in our nursery and in the forest around us, many as an experiment onto the wild rootstocks, as a place to grow out scion wood for future years, to build collections of all the cultivars that can survive our -40 winters and to try new combinations, techniques and timing. Grafting is exciting because it feels like a lost art, and as a hobby it feels like science fiction to turn one tree into another, it's quite fulfilling when you can literally eat the fruits of your labour some years later. Many of the posts you'll find here are not a definative how to graft, they're more about the ongoing open question about what is possible, and follow my thoughts and questions as I've tried out new things over the years.
Questions and comments always welcome to doug@oaksummitnursery.ca.

Spring
81 postsTop working russian pears onto saskatoon, z-grafts continue to be my goto for this. and I'm fluent in all the grafts availble ;) this really is the best option I know of. if the diameters match I switch to whip and tongue. sometimes I'll throw in a bark graft or a modified cleft.
Mustang on chokecherry with an interstem. flowering intensely, pretty sure this can pollinate other plums.
Double working pears, here is paul pear on saskatoon as an interstem, with favoritka red on top. it's experimental, but I've noticed some pears take off and grow more vigorously on saskatoon, and some of these could be interstems.
Apples grafted to saskatoon.
Bolshaya pear full of flowers. It's grafted onto saskatoon, which can be precocious and it's dwarfing. I'm out grafting more pears this week.
Bench grafted plums, done kinda late in the season but maybe the timing will work. second photo is apricots on sandcherry, just finished them so i'm done bench grafting for the year. now just field grafting.. about 30 ea new plum, pear and apple varieties to graft out, just need it to stop raining for the weekend.
Sweet mountain ash grafted to saskatoon. I took cuttings in the fall and grafted some actual mountain ash seedlings this week, but it seems quite compatible with amelanchier alnifolia, you can see the union looks solid and it's healthy.
Prunus americana grafts one year old flowering. excellent for pollinating other plums, easy to graft onto chokecherry. i'm getting about 90% take and winter survival on these, the later photos are grafts from 2022 with very heathy union and in full flower.
Grafting workshop on the weekend, thanks to everyone who came out. we had a dozen people at a nice outdoor location @assiniboinefoodforest and all the workshop fees were a donation. everyone got to bring home a grafted apple tree and extra scion wood, was fun to do
Couple of russian pears grafted in 2022 about to flower. excited to try them. one of the photos is the graft union on saskatoon, holding up well.
Planting apple and pear bench grafts today. around 120 in the first bed, a couple more to go. plums and apricots are still in the greenhouse callousing.
Grafting some lee red chokecherry, it's a variety with purple leaves. also garrington, with larger fruit, and even a yellow fruiting selection.
Z grafts I find are a good option when the scion is smaller, it benefits from the offset to the side to get cambium contact and heals over faster than a cleft graft. it looks a bit like a whip and tongue if you cut the tongue very close to the tip, it's cut with the scion flipped around so feels very different to do. #grafting
A hybrid plum with some simonii in the parentage (25%) growing well directly on chokecherry coming into year 3. will be grafting more of this one out as a potential interstem, toka thrives on chokecherry (50% Prunus simonii) but it's basically too vigorous. search for the perfect chokecherry compatibility continues, eventually I'll write this trial up as a paper and just post it on my blog
Z grafts are my preferred option for top working, when the stock is larger than the scion. especially for prunus, it's stronger and heals faster compared to modified cleft.
Hey made the local paper today, it's an article about an upcoming grafting workshop that we do at the @assiniboinefoodforest and it's just a $40 donation and you get to graft a tree and take it home. I set aside some of our largest rootstocks for it, 15 spots still some left for local folks in the Brandon MB area
Interstem, bridging brookred plum onto chokecherry with a short section of toka
Grafting season starts, all of our apples and pears are bench grafted in march. a couple of weeks inside to callous then back to the root cellar until around the start of may. we're a small nursery and I do all the grafting so the limits are mostly what rootstock we grew and time, but maybe five hundred between apple, pear and plum this spring. I just do them in the evenings so on track for about fifty each day, it's fun and I look forward to it every year. field grafting is done later, that's when the real fun starts around end of april through mid may and I have about as many planned for working over old crabapple, pear and wild rootstocks to grow out new varieties and continuing compatibility trials
My attempt to graft haskap seems to be working, I removed the foil shading the other grafts since they don't seem to be needed, it was just a precaution. this bush is in partial shade. and it experiences -3C for eight hours last night, haskaps shrug off the cold. excited to try and grow out a couple of these maxine thompson varieties, rooting hardwood was tricky with low success. softwood is easy.
Triple worked graft. choke cherry rootstock -> toka interstem -> mustang cherry flowering, second interstem -> apricots just grafted. mustang and last photo is sapalta flowering, unlike other plums these cherry plum hybrids like to flower just one year after grafting.
Apple grafts onto saskatoon two years old. I did these as an experiment with left over scion wood in july. surprisingly they're growing ok, but they're low and vulnerable to deer and rabbits so i've lost some. amelanchier alnifolia, or seevice berry, known as saskatoon grows wild here and has some reputation as a pear rootstock, and now I'm discovering a dwarfing apple rootstock. if it survives for 3 or 5 years and fruits that would be a success for me, at minimum it's a way to grow out scion wood. #grafting
An attractive result, red leafed siberian crabapple on saskatoon. one year old graft leafing out. It's not well known that amelanchier alnifolia has some graft compatibility with apples, I'm trialing it as wild dwarfing apple rootstock. Resistant to apple diseases, grow well in sand, cold hardy to zone 2, dwarfing. precocious? long lived? maybe just for some selection that could serve as an interstem? hey it's a rootstock that grows delicious purple berries.. #grafting #redfleshedapple
Attempting to graft swedish Leningradskaja sweet cherry onto pin cherry. It's zone 4 hardy, maybe even 3/4. I have some slightly sprouted scions so wrapping in foil to keep the sun off. #grafting
Plum grafting in my trial block of chokecherry. a short walk through some of the grafts with interstems that are waking up, with many positive results. this week I'm adding more cultivars, and trying some manchurian apricots, which will be using 2 interstems. choke cherry -> toka -> mustang -> apricot.
Bark grafts on an old pear tree, top worked two years ago from ussurian pear. It's mostly a tree to grow out scion wood. I don't usually make cuts so large but they'll eventually heal over.
Ussurian pear grafted on saskatoon in 2022 flowering in it's third year.
Keeping an eye on things leafing out. it's the height of grafting season right now when the leaves are just starting.
Nice result painting grafts with wax, I made a hot grafting wax from an old recipe with beeswax and pine rosin, paraffin. something enjoyable about using wax. #grafting
Field grafting pears onto saskatoon #grafting. going back to paint the stumps before it rains, the parafilm is ok but not sealed enough
Unwrapping graft unions from last year. If you use budding tape it can stretch and stay on the first winter
Z graft, an alternative to modified cleft when your stock is larger than scions. #grafting
Been preferring z graft as a variation of the modified cleft on larger stumps. this is Prunus americana on Prunus virginiana.. will take some better photos. If I just wait a couple of weeks these can be bark grafts, which are super fast and fun... I'm out field grafting daily for a few weeks until I run out of scions or things to graft them onto ;)
Grafting haskap. will it work? not sure, must be possible. I have three maxine thompson varieties, initially tried to root as hardwood but it didn't respond, maybe a dryer 70-80% perlite mix could do it. haskap roots easily from softwood. anyway I have one scion of each as a backup to graft. I'll also add some foil protection around these to keep the sun off them. when I grafted haskap onto wild honeysuckle last year it didn't leaf out indicating the scions dried out, so will try bagging it. #propagation #haskap #grafting
My haskap grafts from the other day covered for the next 2 weeks with tin foil to keep them cool. This can help take for more sensitive grafts. I might use it on sea buckthorn as well.
A little canopy reduction on this siberian crab I planted twenty years ago. I topped a few larger trees ahead of grafting them over this spring.
B118 rootstocks from our stoolbed. finished apple grafting today, final count around 300 for next year. This is our second winter taking fruit tree orders so still finding out how many to grow.
Sending out scions this week, I have a few left just for shipping in Canada. #grafting
Haskap / honey berry grafted onto wild honeysuckle. There are a few species here, small and bushy rarely 3ft tall, another one that grows like a large shrub 8ft or more, also a vining type. Experimentally I'm trying cultivar haskap onto two of the species to see if they grow, there are some reports that there can be compatibility - they are all in the same genre. The larger bush form will be an advantage if it works, like making a standard with currants. #grafting
Wolf willow and sea buckthorn are in the same family, so I'm trialing grafts with a couple of kinds of sea buckthorn onto the trees. other genera in the family do have compatibility, so maybe there's compatibility here. #grafting
Root grafted prunus onto mustang cherry and some Nanking cherry this morning. I woke up and realized that I could probably trim the roots from small stock trees that were just potted up - to use up left over scions in the fridge and rest this method of grafting on prunus. The source plants are just leafing out and won't be harmed by the pruning, they'll get extra watering. Does root grafting late in the spring work? I don't know, I suspect the trees will need this season and next year in a bed to get up size. Some combinations trialing are Manchurian apricot, prunus maackii (Manchurian cherry), cherry plum, double flowering plum (Prunus × blireiana), American plum, and various plum cultivars onto mustang cherry and Nanking (prunus tomentosa) roots. Grafts were like a reverse modified cleft, this seems the most practical for root grafting. whip and tongue is only possible with thick material, otherwise roots just break. Success is one of the possible outcomes! #grafting
Grafting over sea buckthorn with some cultivars, the stock trees are all male so it will be nice to have some fruit and also grow out softwood to root. #grafting #seabuckthorn #seaberry
Top working stock trees with all sorts of prunus.. mostly to grow budwood for July and more scion wood to collect in the winter. Some trees are just starting to wake up in southern Manitoba, most are still dormant. Apple and pear grafting starts are now and runs through May. #grafting
Bench grafts right before they went in the ground. the first half are on b118 from our new stoolbed, second half are root grafts on M. baccata .. I have a variety of rootstocks and types of grafts this year so it will be interesting to compare how well they grow. #grafting
Bench grafted apples are waking up and ready to plant. #grafting
Top working chokecherry this week. I have so much of it here, working to develop it as a resource with some in house propagation methods. One of my goal this summer will be to use this method to grow out softwood and trial many prunus species and cultivars for softwood rooting potential. Another one is budwood production for July grafting. #grafting
Night grafting with a headlamp. I've had a few late nights working around the nursery with these bright led headlamps. Here I'm working over some tall saskatoon to russian pears at around shoulder height to stay above the browse line. #grafting
Here's how I prep parafilm strips for grafting. about 0.5 x 3" with the backing removed, stuffed into a bag in my grafting belt. Usually I'll cut enough for 50-100 grafts at a time, which is about all I do in a day depending on the weather. #grafting
Toka plum interstem for cherry plum on chokecherry stock. trialing toka and a few others as interstems. #grafting
Field grafting, been waiting all winter for this. ;) last year I made temp labels with a uv resistant garden marker just onto the tail of the white budding tape - and it sucked, they faded within six weeks. This year I've printed vinyl labels ahead of time, so going out to graft I have the permanent label done. I know a metal tag is forever, but these should be good for at least five years. I include details like the year grafted and source in the print, and I fired off 100 labels in a few mins. #grafting
Here's how I like to pack scion wood for field grafting
Chokecherry buds started to swell today in zone 3b southern Manitoba, they're the first trees I've seen start to wake up. this gets things rolling for a grafting project, I have a pile of scion wood to trial on chokecherry for compatibility, and about 50% is going to have an interstem that proved compatible last year. There's 2 goals: 1. to find all compatible prunus on P. Virginiana, and to use them as interstems to make this prolific rootstock work for cultivars plums and other stone fruit around our property and to document the compatibility for others. 2. Developing a system to rapidly grow out cultivar softwood from limited scion material for rooting under mist. own root plums, cherries, apricots
Apple bench grafts for this spring. I didn't count them, should be lots. There's a fun selection of cultivars and style of grafting in here. Our greenhouse is still cool during the day so they're going to callus in here for the next week or so and then go into cold storage until mid May. #grafting #applegrafting
A few apple root grafts from this morning. #grafting
Grafting season started today, the snow finally thawed from our heeled in rootstocks. first graft shown. #grafting #applegrafting
Bench grafting russian pears in my kitchen this morning. #grafting
Apple bench grafts all tucked away. #grafting #appletrees
Trying a few of these, apple root grafts using a 4"length of root onto a 6" scion, the union buried and with this method it's consider beneficial if the scion also roots. Piece root grafting like used to be very common a hundred years ago when everyone was working with seedling rootstocks. I'm interested in these old techniques and their advantages in a cold climate where full sized rootstocks are preferred over dwarfing clonal options. #grafting
Shmaven our polydactyl Siamese cat is very interested in scion wood, here he's helping me unpack some.
One of my grafted Toka plum trees top worked onto choke cherry, start of July last year. #grafting
Going to make some old timey grafting wax. if you ever come across these recipes that list resin or rosin in the ingredients, it's pine resin, or pine gum. Maybe it was just an off the shelf thing years ago, today you can order it from amazon. #grafting
Bridge grafting to fix vole damage #grafting #orchard
Planted our first season's apple bench grafts today. 12 zone 3 hardy varieties on full size Siberian crab apple rootstocks. I've had them in cold storage for about three weeks and the weather has been nice enough they should be ok. A few more nights of light frost likely, but things are leafing out. The apples in our orchard are just starting to show signs of waking up. #grafting #treenursery #permaculture
Wild rootstock project continues, we're grafting plums onto choke cherry and pears onto saskatoon. (prunus virginiana and amelanchier alnifolia) .. selecting vigorous previous year growth, 12-36". the goal is to find the most graft compatible zone 3 hardy species/cultivars. there are some good candidates, we're working not just different cultivars but different species of prunus - all of which are known to have some compatibility but have not been fully explored or studied in our climate and for our hobbyist / food forest application. this also serves as a reserve of scion wood for next year when we'll have many more typical pear and plum rootstocks ready to graft onto. #grafting #permaculture
This season I've been using budding tape for tying grafts in the field, leaving a tail makes for a quick label. I'll come back later on with better tags. UV resistant marker is important. #grafting
Frameworked an old apple tree. it's a parkland I planted in 2004 but never got around to pruning, so it was 25' tall with all the apples up high. Now it's a #frankentree .. #grafting
Bark grafts work well on larger stock and later on in spring when the bark is slipping, it just pos apart in a satisfying way. This is Toka plum on choke cherry, before it was wrapped up. #grafting #fruittree #fruittrees #graftingfruittrees
Patterson pride plum grafted on wild choke cherry three weeks ago. We're running an experiment to see which varieties are most graft compatible and following up on them over time to learn if this can be truely viable for a cold hardy and prolific rootstock. #grafting #graftingtrees #plumgrafting #chokecherry
Apple on Saskatoon graft. In late summer well past grafting season I grafted onto about a dozen small trees, happy to see most are leafing out. Saskatoon is in the Rosacea family with apples and pears and has been used experimentally as a dwarfing rootstock for them. There's some conventional wisdom that pears will work, but few reports about Malus. This is an excellent result and will be followed up on. #grafting
Grafting plums to wild rootstocks all week. The prunus virginiana are just about to lead out. Selecting only vigorous growing trees with 12-36" of growth last year. #grafting #prunusvirginiana #graftingplumtrees #fieldgrafting #permaculture
Red wonder is one of the varieties I grafted this weekend, haven't tried the apples yet but they're hardy to zone 3 and super red so we included them. Might be fun to try breeding with down the road. #graftingtrees #applegrafting
Handful of bench grafted apples on seedling rootstocks. these are parafilm with a grafting rubber, I found this worked well. in the field I would usually tie the graft first, but with handling the wet roots and some smaller diameter material parafilm first seemed better to keep out water and dirt from the union. could have dipped the tops in wax but a small amount of parafilm on the tip was easy enough. By end of the day I had these down to about 90s ea, 30 in an hour includes all the prep #grafting #applegrafting
Logistics of bench grafting when a late snow fall covers the nursery, our rootstocks are all heeled in and frozen under a pile of mulch and snow. Was expecting to bench graft a few hundred apples mid April and set them in the greenhouse to callous, but Manitoba weather has other plans - the highs are still below freezing so maybe.. I should bench graft in may? #backyardnursery #backyardorchard
Scion wood arrived from summerland. 2-3' whips, nice stuff #scions #grafting
Grafting season starts here around the end of April, still trying to decide the best method to tie my grafts. I like the idea of using the budding tape and leaving a tail to quickly label the graft, then come back later with a tag. The natural raffia has some appeal, and when I cut it off it can just go on the ground and biodegrade. Parafilm worked well last season, it's slower than painting the grafts but not much and it's easier to carry around, and it also just biodegrades. #grafting
Grafting plums onto wild choke cherries #grafting #chokecherry #backyardorchard
For whip and tongue grafts parafilm can be coiled like raffia to bing the graft tight, then cover to seal the union and scion. #grafting #applegrafting #backyardorchard
Russian pear grafted into wild Saskatoon #grafting #backyardnursery #fruittreenursery #orchard #backyardorchard
First apple bud from May 1 grafts appeared. Trees are funny, there's still a few hold outs around the orchard that are dormant , others had green tips two weeks ago. #fruittreenursery #grafting #graftingplants #applegrafting
#Grafting season is on in southern Manitoba. #fruittreenursery #fruittrees #backyardnursery
Whip and tongue graft right before wrapping it up tight with parafilm. So many grafts to do this spring, still waiting on the trees
Prunus leafing out. started grafting a few days ago, we're just waiting for trees to wake up and show a little green #plumtree
Summer
56 postsSuper dwarf apples, september ruby grafted onto saskatoon. I did these three years ago and finally got a cage around them last summer, otherwise rabbits. a fun result I think.
Budding, I'm a little hit and miss on it. will see how these do, it's chokecherry.
Double worked plum. on the rootstock is a short length of Prunus americana, and then on top Yakima plum, a cold hardy european plum. will it survive -40? we'll find out, it's in a semi sheltered location, five ft off the ground, and on a super cold hardy rootstock (chokecherry), all of these factors might improve winter survival. just in case I'll cut scions in november.
Prairie magic apple grafted onto saskatoon.
H. sinensis grafted to Hippophae rhamnoides, so it's a larger later ripening sea buckthorn species, female and full of fruit grafted to a male shelterbelt variety.
Black ice plums growing on chokecherry with an american wild plum interstem. one of a few dozen cultivars I'm trying on these interstems this year. vigorously growing chokecherry with a trunk 1" or more, in good sunlight are suitable. I expect the plum to grow a little larger so still waiting to see how balanced the tree is, some of my 2-3 year old grafts may need a stake. I'm seeing americana match the vigour of chokecherry better than toka, which while takes and grows well, the prunus simonii in it is too vigorous and needs some pruning to manage the size. so does americana, trial is ongoing. the deer did some pruning for me this week, good that all of my grafts are up high. #grafting
Intergeneric grafts on saskatoon, first one is hawthorn, which is producing lots of growth with crazy 3" thorns, second is double worked pears, an interstem of a fast growing variety topped with favoritka red, a hard to find russian pear. if you make it to the last one it's a 3 minute walk through of this block of grafts in a partly shaded forest area #grafting
Apricot on chokecherry with americana interstem. i did around 4-5 branches at shoulder height, growing good so far. this double working is basically doing two grafts at once, first the american wild plum goes onto the stock tree, and a few inches up that graft, another scion is grafted on. it only take a couple minutes for each one, we'll see how it grows.
Western sandcherry grafted to *chokecherry*, showing some red indicating stress, early dormancy, no real growth so at least this graft unlikely to pull through. compared to prunus americana grafts which have dark green leaves and a couple ft of growth. I still want sandcherries up high, so will try again next spring with an interstem.
Favoritka pear, on saskatoon 3 year old graft first year flowering. determined to get to try these russian pears this year, maybe I should do a japanese style protective bag over it.
Apple grafts on saskatoon. growing better than you would expect, I have at least a dozen from 2022 growing healthy and some of those are fruiting. no indications of incompatibility really, growth is slower but grafts can still put on 12-18" in a year which is in the healthy range.
Purple/red leafed chokecherry, fun to graft these around and see the color change in june. the new leaves are green and change to purple after about a month
Checking apple grafts on saskatoon. some were done late spring, fun to see them decide to flower. two year old grafts have some fruit, first time.
One of our sweet cherry grafts onto pin cherry, well it made a flower. notable, first Prunus avium flower at our nursery, maybe the first one I've seen. for sure the first sweet cherry blossom on a pin cherry tree #cherryblossom
New pear grafts, about three weeks for them to leaf out, this is when I start to check for rootstock shoot extension and keep it managed, these are top worked saskatoon trees so it's good to leave some lower growth to keep the tree healthy
Short interstems of toka on this combo brookred and brookgold plum grafted onto chokecherry.
Walk around my experimental pear orchard, grafted onto saskatoon. five min video. maybe I should be shooting for youtube, really this is mostly for my own video documentation, or if you've thought about growing pears on saskatoon rootstock this give you an idea of what 1-3 year old grafts can look like. site conditions will change the results, this is on established trees at shoulder height to stay above the browse line, also dense with some shade. hoping to start getting fruit next year, and I expect most will need staking.
A few apples ok this multi-grafted tree, starting to get some color
Two chokecherry cultivars, first one is lee red, second is probably Schubert. they graft easily onto wild chokecherry and add some color. Lee Red has larger leaves on my grafts, not sure if that's common, it does seem to grow vigorously. #chokecherry #grafting
Apples I grafted onto a wild crab in our yard a few years ago, lost the tag and forget the variety. norkent?
First fruit, this is apple on saskatoon. It's a small graft in the shade from two years ago, but hey it's an apple growing on a saskatoon tree.
More photos of baker's gold apricot. my review is they're good, similar to ones i've had from the grocery store, larger. clingstone, not tart, mild flavour, hey it's the first apricot I've had in a long while and a month earlier than any plums around, a real treat. planning to graft some of these for next year, my sand cherry seedlings are sizing up.
Experimental apple grafts from 2022, finally caged. a year ago they were a rabbit's lunch and now have recovered, maybe 12" of growth this summer. these are on saskatoon which I expect to dwarf them, no one seems to know if it's compatible as an apple rootstock. for new grafts I start at shoulder height to be above the browse line.
Hawthorn grafted onto saskatoon. There's an interesting overlap of graft compatibility in the Rosacea family between several genuses, pear and quince, saskatoon and aronia, hawthorn and apple, and I have to assume more if you find the right interstems. there are some cool combinations to be tried and make the most inteteresting trees, these ones if the grafts endure will have purple berries and also 2" thorns with clusters of red fruit. #grafting
Spring american wild plum grafts onto chokecherry. maybe six weeks old. I trim back most of the epicormic growth but not all of it, actually letting it reduce vigour improves hardening off for the first winter. #grafting
Graft union for this one year old red leafed malus baccata on our native amelanchier alnifolia, an unusual combination that seems to be healthy and somewhat graft compatible. #grafting #applegrafting
Grafting wild canadian plum
Large pear and apple trees top worked last year into multiple cultivars mostly as a store for scion wood. #grafting
Chip budding apricots hardy to zone 3 -40C. this year i have them on mustang, next year also onto western sand cherry. If you have labels ready then it's easy to keep track and just graft lots of variety. #grafting
Chip budding this weekend, plums and apricots. #grafting
Finished budding plums and apricots for the year I think. Maybe I'll do more, not sure how late it can go. In warmer places I hear July is the right time, but here early august seems like the right timing to have mature budwood. #grafting
Sweet mountain ash grafts on saskatoon. #grafting
Checking apple grafts top worked onto saskatoon this spring. #grafting

Red leafed chokecherry grafted onto wild chokecherry. #grafting
Toka plum on chokecherry grafted last spring.
Block of black chokecherry, prunus virginiana var melanocarpa grafted over to an assortment of other prunus to trial compatibility, grow out budwood for august budding onto rootstocks, and to produce softwood for rooting. So far this season take was high across every prunus species, and at 6-8 weeks every graft that leafed out continues to grow. Trialing various pruning and interstem interventions to keep as many growing until dormancy as I can, which can them be a reserve of dormant scion wood for next spring. Eventually I'll have an orchard of mature prunus for a more permanent resource, but chokecherry being common and plentiful here is working well so far. #propagation
Red siberian crabapple selection grafted to saskatoon / serviceberry one month ago. Out of all the apple grafts I've trialed onto A. alnifolia this one has had the best early growth. #grafting
On old harbin pear tree top worked to produce scion wood. Working over old trees like this can take one scion and multiply it for the next grafting season. This spring I used many of the scions to graft new pears, and also to graft onto saskatoon. #propagation
Some late summer t budding, apple on saskatoon. the bark is still slipping on some trees. on smaller stocks or if the bark or if the bark doesn't want to cooperate then a chip bud works. These can be done late in the season because they just need take and then usually wait for spring to grow. #budgrafting #tbudgrafting #grafting
Chip budding plums. We've had by far the best result with Toka plum this year in our experimental grading trials onto wild rootstock, some of our grafts done in may have grown 4' with secondary scaffolds. We're now chip budding other cultivars onto Toka to use it as in interstem. #grafting
Whip & tongue graft union. Field grafted domestic plum on Prunus virginiana at nine weeks. This year my hobby experiment as an aside to our nursery has been to explore graft compatibility with wild rootstocks, include the P. virginiana and A. alnifolia around our property. So far results have been better than expected. At the very minimum we have a surplus of scion wood for bud grafting our mustang rootstocks this month and dormant plum, pear and apple scions next year's grafting season. Best case these are long lived, or a more tempered expectation is that some of them will out preform others. A range of grafting techniques, timing, rootstock / frame tree size, and caliper were selected. Two dozen zone 3 hardy plum, a dozen pear and as many apple were grafted all around to see how well they would grow and collect real data on compatibility. So far in the first season we're seeing vigorous healthy growth across the board. #grafting
Modified cleft graft, you can see the small flap on the left. we're unwrapping plum grafts this week and checking on how they've healed, we did most of these grafts in early May. Our pear and apple grafts can wait a while because we did them early June when the trees were coming out of dormancy. #grafting
We had a wind storm this morning that broke off this grafted plum branch (shown upside down), there was a couple feet of flush growth above it. at 8 weeks there's more girdling than expected. Maybe I wrapped it too tight. One thing to pay close attention to is the strength of the graft union, if the tissues are less than compatible it won't be strong. In this case I think it's a girdled branch. I'll be removing the budding tape on all of our early May grafts this week and inspecting them. #grafting
Summer update for our plum on wild choke cherry grafts. Nearly every prunus variety we tried has grown, the most vigorous growth on this set of trees on a sunny hill. Success with this type of grafting in the first year seems to depend on the age and location of the root stock, as well as the amount of undergrowth and management of new suckering growth. I held off trying this for years because of anecdotal reports that it wouldn't work. My approach here is to question assumptions, research old studies where it was tried and do it for myself, there are quite a few variables, including genetic compatibility variation with specific individuals within a species. Choke cherry is prolific across forested areas in Canada, but there are no wood lots, parks, hiking trails or backyards full of them made into food forests by grafting them over.
Fall Red apple on wild saskatoon in its second season. At the end of grafting season last year I tried a few malus on amelanchier intergeneric grafts. It was july before they took so little growth last year, but I happy to see most of the grafts survived and and growing this summer. Fall red seems to have the strongest growth, but more trials and seasons of observation will tell. For now at minimum I know how to save left over scion wood if needed. What's promising just like our prunus trials is that we don't need every cultivar to do well on saskatoon, we just need one and if can serve as an interstem. Our property happens to have established saskatoon underbrush almost everywhere mixed with the choke cherry and hazel, and I'm excited to find out what can be grafted onto it and exactly how long lived these grafts can be. The trees live for maybe 40 years and will certainly be more dwarfing that a full sized apple rootstock. #applegrafting #serviceberry
Plum frameworked onto choke cherry at five weeks. #grafting #plumgrafting #intergeneric
Plum grafts on wild choke cherry. Our grafts were all done in the first three weeks of May and many are showing signs of growth, so a successful union so far. The take rate seems to correlate with age of the root stock and competing vegetation on it more than shade, type of graft or plum cultivar. In the fall we'll post a spreadsheet with some data, this is a multi year project to determine compatibility in cold hardy Prunus cultivars on the most prolific and hardy wild Prunus rootstock (Prunus virginiana) in our climate zone 3, southern Manitoba. #grafting #chokecherry
Nanking cherry grafted on wild chokecherry. (Prunus tomentosa on Prunus virginiana). Will it take? I'm hopeful for this combination. Also it's fun when scions blossom, feels like a small success. #grafting #nankingcherry #cherryblossom #cherryblossoms
Small choke cherry tree grafted over to plums at three weeks. keeping the under growth continually rubbed off to ensure all of the growth is focused on the grafts seems key. For larger trees Instead of defoliating I've been topping all the other branches to try and give the grafts apical dominance. #grafting
Apples grafted on saskatoon / service berry last month. September ruby, chestnut crab, Goodland, norkent. So far they're healthy and growing as fast as anything I grafted on an apple tree this year. There's at least early indication of good compatibility with these cold hardy cultivars. could this be just an excellent cold hardy dwarfing rootstock? Last winter we had a dozen nights colder than -35C, and the saskatoons are bullet proof to the cold. #applegrafting
Goodland apples are flowing this week. This tree and a few scions I've grafted out are all flowering at once. Takes a late spring for an apple tree to wait for the summer solstice to flower.
Grafted plums are taking off. This one is Nanking cherry on the left and Toka plum on the right. These are putting on better growth than our orchard plum trees on their third leaf, the Prunus virginiana frame tree is well adapted to our sandy soil and puts on vigorous growth. How long will these grafts survive? Of the dozen various Prunus cultivars and species we grafted out this year will some of them have good compatibility? #grafting #plumtrees #chokecherry
Progress on one of our multi grafted prunus virginiana. This size of tree seems to produce the most vigorous growth. #grafting #graftingplants #plumtree

Fall
17 postsA new unnamed plum that has somewhat graftable to chokecherry, maybe fruit next year. the last couple photos are mustang on chokecherry with a toka interstem. experimental plum grafts in this test area are helping sort out chokecherry graft compatibility across all of the zone 3 hardy plums.
Sweet cherry grafts onto pin cherry, in zone 3. will they survive and fruit? no idea, possibly first time anyone has tried this specific combination of swedish varieties (hardy to at least -30C) on top of some wild pin cherry in a zone that reaches -42C most winters. 5 ft off the ground help with deer grazing, and can help with air temperature, but surely this is an exposed location at the end of our lane, fully above the snow, but sheltered by some tall trees. #sweetcherry #zonepushing
Parkland apple grafted to saskatoon, second year. a few cultivars have had stand out growth on this unconventional apple rootstock, might need to replicate to know if it's a one off or better compatibility. one way to look at long term health is the graft union, which looks pretty good. trial ongoing.
Prunus americana, wild plum. I've been growing a couple of selections that are graft compatible with prunus virginiana. it takes some years to grow out more scion wood but the process has exponential returns. I have so many prunus cultivars and species that I want to grow, so turning the forest of established chokecherry into a canvas with interstems is such a rewarding project. of note, the other wild plum prunus nigra doesn't seem compatible at all with chokecherry directly, but it might be with an interstem.
Video is triple worked prunus, two interstems between a chokecherry rootstock and apricot on top. this worked well. the other photos are z graft unions from this spring, plums onto chokecherry. it makes a strong union that heals quickly, it's in between modified cleft and whip & tongue #grafting
Sweet cherry growing on pin cherry. leningradskaja may survive the winter here, but if it doesn't I've collected scions early and can try again next year. in this way by serial grafting scion wood can be produced.. and in this case even without prunus avium rootstocks #grafting #sweetcherry
Graft union with kyrgyz plum, prunus domestica, on top of a toka hybrid plum interstem. grew about 4 ft this summer, a way to collect scion wood. PD new growth has a soft almost fuzzy bloom and purple bark. this plum will likely die back to the union unless we get a very mild winter, but it's ok I can regraft it. the idea is to have some less cold hardy prunus growing to ship to warmer provinces, but also for future breeding. #grafting
Collecting scion wood from this old pear tree. I top worked it over to different varieties a couple of years ago and now it's good for saving these genetics and producing material for grafting every year.
Hawthorn grafted to saskatoon. liking the z graft, heals over better than modified cleft #grafting
Grafting sea buckthorn is tricky, but possible. Here's a fruiting branch grafted last spring from chinese sea buckthorn, H. sinensis onto a male H. rhamnoides , probably Indian Summer a shelterbelt seed strain. Sinesis gets larger, fruits a month later, and has a sharp citrus tasty flavour.
Couple of Toka plum from this experimental tree. wow the fruity bubblegum flavour is distinct. grafted onto chokecherry rootstock, the top is heavy and outgrowing the base so needs some steaking. So far the graft union is sound, and I'm seeing vigor settle down this year. Would have had a full crop with a pollinator nearby, adding americana grafts around for that. I have four of these 3 year old grafts and it's working, though I think Toka will end up being best suited as an interstem.
Collecting some scion wood today. in cold climates with a long winter this can be preferable to the spring time, so long as you have a strategy for storage that's at least as good as outside on the tree. storing in the new root cellar where I can keep it cool and humid, probably bagged in some peat. one more advantage here is varieties that are not quite cold hardy here can be grown, just need to graft it out every spring.
Winter gardening, I was going to wait for things to warm up but looks like winter is here. lifting apple bench grafts after a warm fall followed by snow and cold snap. usually I would be lifting these after the leaves are all dropped, but check the forecast and the temp graph photos, looks like snow is here to stay until the ground freezes some time in the next week. second year lifting bare root trees in the fall, happy I have the new root cellar for these to store in. I now wonder how often I'll be doing this in the snow! a very canadian experience.. #backyardnursery
Apple trees bench grafted this spring. high density maybe 6" centers in 3 x 20 ft bed. Most are around 2 ft and they were transplanted in may after the ground thawed, we had snow until mid april, short season here. I keep these under hoops with netting to keep our curious deer who would see it as a salad bar, also rabbits. one hoop covers 2 rows so it's easy to duck under and use the path to work between them.
It's nice out so I went and collected some early scion wood. In cold areas there's some benefits to doing this in November, so long as you store them in the right conditions. Early collection gets ahead of possible winter kill, the snow is less deep than in March, and some places stop taking scion wood orders in Jan so we'll know what we need. Storage for us is in a dedicated fridge at 1C / 34F along with our seeds, and they're kept on the dry side, minimal material added to the bags just to keep them from desiccating, will be trying peat this winter. As a precaution I only collected half the wood, will get the rest in March. For reference, the university of Sask also in our climate zone recommends Nov 1 collection and storage with fairly dry peat. #scionwood
I made a new blog post as a follow up to our wild rootstock grafting experiment. Also our site has a new design, and I've filled up the sections with most of the trees we'll have available this winter. There's a link in our profile to our site or you can type in oaksummitnursery.ca
A couple of norkent apple grafted onto saskatoon / service berry this spring. We had the same take with apple as we did pear, about 90% of the spring grafts on A. alnifolia are alive although the pear grew more, some of the pear grafts grew 3' and the average apple grew 1-2'. #appletree #grafting #serviceberry
Winter
10 postsChecking on sweet cherry grafted onto pin cherry, has anyone else tried this? I'll be amazed if the grafts survive, we've had quite a few nights below -35.. but a quick scratch test looks alive, though I guess cold damage might not appear until spring? the premise I'm testing is this european cultivar was reported to survive zone 4 winters and flower, and here I have it on a super cold hardy rootstock which could possibly provide some cold hardiness. The most likely outcome is that I'll regraft it lower where the snow will cover the branches, but just maybe these will pull through. #cherry #cherrygrafting #grafting
Plum scion wood bundles that were cut early, just checking in on the moisture. looks good. Most people cut scions in spring, but there are good reasons to do some earlier. You can cut dormant scion wood any time after the leaves drop, and it can be easier in late november here before the snow gets deep. Another reason is growing borderline or out of zone varieties, early scions before the coldest months won't have any winter die back, like a backup in case it needs to get regrafted. For long term storage, nov - april I wax the ends and throw a handful of damp peat moss in the bag to buffer moisture and condensation. then store them in a fridge. or fridges. #scionwood
Root grafted apples. an old school technique that used to be the most common way to propagate them. I found the trees take an extra year to grow, these were grafted spring 2023. Inspired to research this in old gardening and nursery books after reading an article by @elizapples #grafting #rootgraft #applegrafting
Someone else noticed you can graft toka (prunus simonii hybrid) to chokecherry... in 1887 in this update from the michigan horticultural society. google books search https://www.google.ca/books/edition/Annual_Report_of_the_Secretary_of_the_St/wHU5AQAAMAAJ?hl=en&gbpv=1&dq=prunus+virginiana+grafted&pg=PA100&printsec=frontcover
Bench grafting apples last spring, the conventional and a few root grafts. I so look forward to doing it again this year, I didn't count but there were at least a few hundred and I'll do more this year. So far I've preferred parafilm and then a rubber on top. maybe I don't need both, but parafilm quickly holds a whip and tongue together and keeps it clean and dry inside, and the rubber feel like it holds everything tight.
Softwood propagation and fall budding around our Manitoba nursery last summer. #propagation
A few field grafts from last season in early summer. I spend all winter dreaming about grafting.. and stock piling scion wood. #graftingfruittrees
Root grafting, excited to try some if these when I'm bench grafting in April #grafting
I've been thinking about this double whip graft, seem like it would heal over better than modified cleft. has anyone tried it? #grafting
Toka plum on wild chokecherry grafts. This one hybrid variety had the best compatibility and put on 3-4ft of growth last year. I've left them to overwinter with budding tape in place to add a little insulation from sun scald, hoping these make it through the winter. later this spring I'll be trialing Toka and a few others as an interstem on many more prunus varieties with the goal of finding compatible combinations for zone 3 hardy prunus to graft onto the prolific choke cherry around most of Canada. #grafting
