Hi all, new member getting used to navigating this forum. Hope this works. Previous owner of mature Red Dragon Japanese Laceleaf Maple had to remove the tree quickly due to demolition. No rootball prep and I got it with bare roots last Aug. Used root growth with some sand at bottom. Trickle fed it for couple weeks. This spring produced some underdeveloped leaves on some branches. Thought all was good. This week all the leaves are curled, withered and dried.the pix showed it at its beauty before uprooting, last fall, this spring and now. Literature says could be due to under watering, over watering and disease. Also read that may come back next season or new leaves this season. Soil seems to be draining well. Will scratch test branches later for life. What to do? Thx all.
