root grafted prunus onto mustang cherry and some Nanking cherry

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
