Burying the graft
I recently acquired a couple John Pair Sugar Maples. These trees are approximately 18" and they were grafted onto standard Sugar Maple stock.
I live in Texas and have wanted a drought hardy Sugar Maple for some time. I was wondering if it would be beneficial in this case to bury the graft of these trees and allow the scion to root, which would result in a much more drought tolerant root system coming from the Caddo Maple part.
I understand that a trees root flare usually should be exposed at planting and that grafted trees usually have a more desirable rootstock. However, in my case I am wanting the drought hardy characteristics of the Caddo Maple top.
Should I plant the tree deep and try to root the scion, or just plant the trees at the normal level?
