Whip and Tongue Viability
I am wondering how long to give a couple of whip and tongue apple grafts. They were grafted third week of March and the temps have ranged between high 30sF - low 60sF. It has been a month since grafting.
The smaller-diameter apple grafts are putting out green buds while the larger winter-apple scions only show a tiny sliver of gray (and my older apples are tight bud phase now). I have not yet rubbed the rootstock buds off just in case. Do they still have a chance?
Also when is the best time to remove the rubberbands?
Thanks in advance.
