Saving Canada wild plum seeds for next season

Oak Summit Nursery · Southern Manitoba

cleaning wild plums this week. I keep some of them for jam but often they're picked overripe and from the ground, and the best I can do is eat some and then keep all of the seed. the funny thing is that most of the fruit I collect for the nursery is from locations where it was just going to fall and become compost or food for wildlife, so I think giving every plum seed the opportunity to grow into a tree is a good result. in the case of these hard to find canada wild plums it's a conservation effort to distribute the genetics, their value in a home orchard or in the landscape is quite high to pollinate other plums, and as a great native tree overall. a net positive to eventually feed more wildlife everywhere they're planted for sure. these plums will be to help stock the nursery next spring and keep our seed shop going through the winter. if you want to grow plums. you can plant the seeds in the fall or start them in the fridge in some damp peat moss through the winter and that helps break their dormancy so that the seeds will germinate in the spring.
