Unfortunately, our recent vacation corresponded with the hottest days of the summer, and we came home to find our potted JM a crispy critter. About 3/4 of the leaves in the upper canopy are all brown and dead, but there are signs of greenery in the lower quarter of this small (about 3') potted tree. Should I do anything at all to the tree (besides keep it watered)? Should I remove the crispy leaves or let 'em stay where they are? Any hope of a recovery this summer, or will I not see any new leaves until next spring?
