What does an overwatered Gollum jade look like?

This plant needs to be watered just right. If you give it too much water, it'll start to look a little sad. The leaves will turn yellow, and the stems and roots will rot. You'll probably see mold or moss on the leaves or stems, too.

This plant will show yellow leaves, root rot, and even fungus growing

Ugh! That'll make it look like yellowing leaves, leaf drop, discolored leaves, and fungal growth.
