I'm planning to get some scionwood from my brother at some point in the next month or so (from the tree discussed
in this other thread), and I have two different seedlings in my greenhouse that I could potentially use as rootstock, but would prefer to use the smaller one, which is the seedling of the tree I'll be grafting. Here's what it looks like now:
I don't know if that seedling (about 7 months old, stunted from a winter in a cool greenhouse) is too small for successful grafting, though. I know there are some grafting techniques (Z graft, for example) that can be used when a rootstock is thinner than the scionwood, but I'm not sure if those work well with mangos.
My other option to use as rootstock is a two year-old Ataulfo seedling that I have planted in the ground in the greenhouse, but I kind of want to grow that one out, even though it's a much better size for matching scionwood. Here's what that looks like:
Is there any way to use the little seedling without waiting for it to grow more first, or should I stick with the larger one instead?
I'm sorry if this has been discussed on here already, I tried to use the search feature and couldn't find any on-point discussions.
