I did an inverted t-bud of Golden Nugget on 9-17-17. It healed up well, so I broke the top of the tree over pretty quickly, but now it's just sitting there refusing to grow. The rootstock has tried to send out some growth above and below the GN a couple of times, but I have broken them off before they could get going.
The tree was in a shady area while it initially recovered, but now it is in my winter grow room. Temps staying between 70 and 90F. Any suggestions guys?
