At the end of October I repotted my two dieffenbachia from a shared 8” pot to a 10” pot. Both went into transplant shock and flopped over soon after. I used a tomato cage (upside down because I didn’t want to risk the stakes poking into the roots) to brace them. One has since perked back up and looks normal again.
The other is still limp in both the stem and leaves, and the stem has developed odd spots and texture changes. There are whitish/ brown bumps, plus some wrinkled, indented areas. The stem is mostly firm, but slightly softer than before around the lighter-green, wrinkled sections.
I couldn’t find similar examples online, so I asked ChatGPT. The response was that it may be callus-like, corky tissue caused by stress or handling damage, which can happen during transplant shock, and that this scarring could also make it harder for the plant to move water up the stem which it was already struggling with due to root disturbance during repotting.
Has anyone seen something like this on a dieffenbachia? Does this look like normal stress damage that I should give time to heal, or does it look more like rot where it would be safer to cut the healthy top and propagate?
It’s about 2ft back from a NW facing window.
