I took two air-layered cuttings about 1.5 month ago. One with barely any root development, the other with roots running around 2" -I managed to break some of them with poor handling as well. Planted both in 5-gallon pots using kellogg patio plus and left outside in full sun from day one. They were ravaged by santa ana wind several days after & reduced to just twigs. But I kept on watering it thoroughly every other day until now. They're both showing new growth, though the cutting with better developed roots growing much faster.

If the root ball look healthy, it should be fine. Just give it time to recover. If the stems are still green, it's still good. Heck, some branch tips on mine are completely brown & dried two weeks in but the rest of the plant survived. They're pretty hardy so no need to stress.

That's a very unhappy plant for sure. I would just leave it alone and see if it wants to begin growing again. The more you do to it, at this point, the more disruption in the potential re-growth you will have. The tree may be not re-grow and you may have to let the nursey know so that they can replace it. Time will tell. Good luck!

I repotted a wax jambu similarly. It wilted soon after, but I kept it in the shade. It bounced back after a week. It was one of the easier plants to repot for me.

I did the same to a green sapote and it went on a slow decline like your plant in the picture. It eventually died. The roots couldn't sustain the plant with enough water. Looking back, I should have increased the humidity with a plastic bag over the top of the plant. Whatever you do, I hope it pulls through.

Thanks, Tim! That's good to know. The roots looked fine just really small for the size of the tree, but I figured if the stems stayed green it would recover eventually (just needed some reassurance since I know nothing about tropical fruit trees). I read that jambus were pretty resilient but this experience had me doubting that. Your experience has given me some hope all is not lost. I'll just have to keep watching to make sure none of the branches die back (or die back too much).
@Harry, yes I figured nothing to do at this point but wait it out. Just wanted to see if anyone could give me some hope. :) If it dies I doubt I will contact the nursery as it was probably my fault. Thanks very much!!

@pepperot: Oh no! Well humidity is not a problem around here. We've had a very wet spring and our summers are usually very humid. Yesterday evening it rained (after being beautiful all day) and I put it out in the rain for a little while. I misted the whole tree the day before with some diluted sea kelp to see if that would help the leaves but not sure if it did or not. It's going to be raining for the next week (it's been raining pretty much for weeks around here with only a few days of sun in between and everything is growing and blooming like crazy) so I'll be moving it in and out of the rain as our tap water is very hard. I hope it's not doing the "slow decline" that your sapote did but if it is there really is nothing more I can do. I'll just have to be patient. I appreciate the feedback!!
