So, as I reported in mid-June my Sugar Belle that I repotted was putting on some very nice, luscious growth and contimued to do so until about 2 weeks ago. Then one side of the tree began to wilt and droop, then a week later the other half wilted. No brown edges or discoloration on the leaves, no insects and nothing obvious to cause this. The tree is now dead. I examined the roots today after I pulled it out of the pot and they look perfectly normal to my eye. Any ideas about this mystery?
