So I just planted a Shiro Japanese plum tree with the plan of using it as a mother tree and grafting on two varieties to it (Laroda and Satsuma). I’m planning on making the Shiro 1/3rd of the tree to be on the northern side for vigor management and have already planted it with the lowest branch pointing North.
But now I don’t know where to go from here. I thought the tree was going to come as a whip and I was going to let it grow out for a season but instead it came with a couple of well spaced scaffolds that I cant utilize because I don’t have any scion to graft right now.
I’m not sure how I’m going to convert 2/3 of the tree into two other varieties next year without taking off all the new growth it puts on this year.
You got a very nice tree.
You have a branch that is almost as thick as the main trunk, this branch will eventually be the dominant branch. If you are going to keep this branch , if I were you, I would cut this branch short and plant it North side, place the lower weaker branch on South side.hopefully, all branches are growing in good balance. If it was my tree, I would trim that branch off and select 4 remaining more or less balanced branches for scaffold. My two cents.
If the tree roots started to grow, the branch leafs out, I might be able to send you some satsuma, larova, (and Santa Rosa if you want, ) scions to graft this year… Let me check my scions first, I keep few scions after pruning most of the time, but not every time .
My scions are all stored in 32-33 degree and all deep sleep. I don’t want to take them in and out often. So keep me posted, I should start to graft plum in a month or so. By that time, you should know how well your tree is doing too
Looks like almost every graft took. Likely the definition of dumb luck because I grafted at temperatures considered too low (shortly after the tree began to leaf out, when mid 30’s to high 50’s for a couple days straight).
Of the 16(?) grafts one is very sluggish, just leafing out now, and one looks to have been killed by the frost when we had a 25°F low. The leaves on all the grafts are kind of deformed but I suspect thats from the several nights of frost that happened 2-3 weeks ago. All the grafts seem to be taking off again with the last few warm days we’ve had.
So far Tomcot apricot appears to be compatible with Shiro plum. Also grafted on the tree now is Satsuma and Laroda. There will now be 4 scaffolds because I intend to let the Shiro nurse branch (the small one) to continue to grow out.
I’ll probably try my hand at doing some bark grafts to fill out the canopy a bit and as insurance for the two grafts that are struggling.
Yeah, all the grafts took and are growing strong. Got some plums last year but I think I started spraying too late because they mostly got taken out by plum curculio. No apricots last year because of late frost or something, fingers crossed for this year.
All the claims about Shirl’s vigor are true, if any Shiro branch is left unchecked it will try to take up all the sun and shade everything else out.
