I have a coleus plant in a pretty large pot. I accidentally left it outside in the cold overnight and almost all the leaves were drooping or dead from the cold. I pruned them off and left the plant with a few good leaves. However most of the stalks are bare. The tallest one is about 1'8". I have been reading that they should be cut once they reach 4"-6". Should I go on and cut the stalks down that low or do I risk putting my plant into shock? Please help me. I dont want to lose my plant.
