A few weeks ago we had a little heatwave and I guess I had let a few plants go a little bit too long without watering. My 2.5 ft tall young pawpaw dropped most of its leaves, and then the remaining few several days later even after watering. I've since been much more careful about regular watering and moved it to a more heavily shaded location, but so far no signs of bouncing back unlike its neighboring white sapote and cherimoyas that also got scortched and dropped some leaves.
Is pawpaw one of those trees that only puts out new leaves in spring and I just have to wait? I scratched the bark and its still green, but the branch tips looking dried out have me worried I should be doing more now or it might not make it until then.
