Oh boy, where do I start. I've had this plant for years - it started as a clipping off my great grandmother's jade plant. It has been having issues for over a year now and I'm really struggling to bring it back. It used to be very full but over a year ago it started having issues.
First, branches started to get mushy and fall...then VERY large branches started to die off. Eventually, I started to notice teeny tiny white bugs on the top of the soil. I must have been overwatering and I think it resulted in some issues with the roots (possibly root rot?). I repotted the plant, got rid of as much of the original soil as possible and put it in a much smaller pot (cactus/succulent soil). The branches firmed up eventually and I stopped losing branches. I'm also watering it very infrequently now..and much smaller amounts of water...trying to dry the roots out. The base of the plant is still firm...nothing right now feels mushy.
It's not bouncing back though. I get new growth but it's slow and very small. Currently, the tree is VERY thin and now there's mold/mildew on the leaves. I'm trying to figure out if I treat the mildew with a fungicide or do something more drastic like cutting it down or taking the roots off completely and re-rooting it?
Any advice!?
