My container Coleus is getting tall and so top-heave that the stalks are breaking. What should I do?
Well, I can think of 4 options. 1. prune the plant 2. drive a stake into the ground and tie the pot to the stake 3. repot and put a stone in the bottom of the pot or 4. put the plant, pot and all, inside a larger pot. (thrift shops are good places to look for pots)
I hope one of these works out for you.
