My potted Rainbow Riviera is tall. About 8 feet tall with a substantial "Y" branch at the top. (The third branch broke off when it toppled over). It has been growing in a large pot. The trunk is about 3" in diameter. Can I cut this tree?? In half? You know how large the leaves get on this variety. They are sometimes 18" long! I hate to think how top heavy it will be this summer. It will topple over again for sure! Help? Suggestions? Hints? I will get a picture of it in a moment.
