Hi everyone,

I have managed to stabilize most of these plants, except for the willow leaf fig. That one is still slowly losing its leaves.
Attached is how it looks after 2 months. It has new growth, and the leaves aren't droopy like before, but you can see that I've lost a number of lower branches entirely.

I am having trouble finding resources online for why a plant like this would get dried up leaves. Any help is greatly appreciated. Thanks.
