Question
I have two jade plants in bonsai-type pot arrangments, both cuttings from the same tree (which was divided about 5 years ago). They are in a south-facing window that is partially blocked by an adjacent building, so they receive about 4 hours of direct light per day. I have them on an every-other-week watering schedule, letting them dry out in between.  They have been in this arrangement since February of this year.

Both plants have been doing well, have a nice green color and plump leaves. They even started putting out new growth about a month ago. Over the past two or three weeks, however, the leaves on one of the plants have become wrinkled--over 90% of the plant. I have checked for soft spots (none), given additional water (no results), added fertilizer (no results). There is no yellowing evident. The other jade, which has had the same conditions, is thriving.

Beside repotting, which is my last hope, do you have any suggestions on what might be the problem?

Answer
Hi Michelle,

Shriveled Jade leaves that do not recover after watering are a good indication that the roots are no longer absorbing water. The reason for that is that they were either damaged when they were potted or, more likely, the roots have rotted.

Dividing and repotting plants such as Jades is a tricky process and it is easy to damage the roots, use the wrong soil mix or use a pot that is too large. I can't say specifically why one plant has suffered while the other is thriving, but it is impossible to treat two plants exactly in the same way, especially when it comes to repotting.

Root rot is usually terminal once the plant starts to show obvious symptoms. Repotting will not save it. Taking it out of its pot will allow you to confirm the condition of the roots, but that won't cure the problem.

Assuming the roots have rotted, all you can do to salvage the plant is to take some healthy stem cuttings to propagate a new plant.

Please let me know if any of this is unclear or if you have any additional questions.
