Dan...
Two years ago, at just about this time, my dad became seriously ill, and required my constant attention. I forgot to water my containerized "Atreano" tree for over two weeks, and the leaves looked like drying tobacco. For sure, I thought, I killed my prize tree, or, that it would die a slow death through the coming winter because of lack of energy reserves still locked into the dead leaves, and not in the roots. Far too late into the season for a new crop of leaves to re-grow...which probably would've been worse than no leaves. I bit my nails. I was distraught. Crap!
I continued to water the tree well into late December, and then stored the tree in my unheated shed, as usual. In the spring, the tree re-sprouted like nothing happened, and grew a great crop of figs that year.
Give your treelet some TLC, whistle a happy tune...and I'm sure it will pull through with flying colors.
Good luck.
