Below is a picture (a bit out of focus, sorry) of what a lot of my bench grafts are starting to look like. This particular one is an interstem of M27 on M111 rootstock with Chestnut Crab scion.
I’ve been pinching buds off the interstem and rootstock of all my grafts since the beginning, but have left all growth on the scion so far. I left most of my scions with 3-4 buds each and most buds are growing. As you can see in this one, the longest shoot is often not at the top. Since I understand my goal for the first year of growth to be a single whip, I know I should concentrate the trees energy into one shoot at some point. Do I do that now? And if so should I pick one of the lower shoots if they’re the longest and just prune the whole top of the scion off above that shoot?
As a possible added consideration, some of these buds had flowers and on some they are still little rossettes of leaves, not shoots, so I’m wondering if they are future fruiting spurs. My intention is to keep these as small stepover trees around other gardens, so is there any benefit to leaving some of these, or just cutting the shoots I’m getting rid of above the first couple leaves, if I really want to keep these very small and am happy to push them into fruiting mode as early as possible.
Thanks for any advice.
