Is there any reason not to let this rootstock shoot grow out and fruit? I’d like to have a source of seeds for rootstock purposes, but not if there would be any problem for the grafted variety (Pixie, the only tree my wife has specifically requested in the greenhouse).
Let it grow about 6 inches and nip it in the top bud. After it hardens off you can remove it and root it in potting soil in a small cup. PT roots well.
I was thinking it would grow faster and fruit sooner if it stays on the tree. Is there any reason not to keep a lower branch that’s from the rootstock? Will it cause the grafted variety to grow poorly, or will it grow poorly itself as a lower branch?
The trifoliate rootstock will cause the fruiting part to die in a few years. Your rootstock is from seed and will need to grow to about 8 feet tall before it will set fruit.
That’s a shame. For my avocados, I like to let the rootstock grow along with the grafted variety, and as long as I’m good about keeping them pruned evenly it doesn’t seem they have a tendency to abort/self-prune the graft when you do that. Sad to hear citrus/poncirus are different in that regard.
Thanks!
I would remove the shoot from the rootstock.
Seeds / seedlings of trifoliate are easy to come by.
You really don’t want that rootsprout to grow to a size where it will fruit .
