Is it possible to cut down a rubber plant that has grown too tall or would it look bad?
This can be done in March or April, just as the growing season gets going. It is almost always a good plan to re-pot into a larger pot, using half garden soil and half compost.
Keep the plant, after pruning, in a bright sunny place, even if it has no leaves left, and keep it just nicely moist and feed it when the first new shoots appear. It takes a full growing season to make some new growth and will look great after a second summer.
