I love the bright, beautiful colors this croton delivers. However, I've had my plant about a year, a year and a half, and it remains leggy and wimpy. It puts out leaves at the top, but doesn't bring any more leads. It's only got a few rounds of leaves at the top so I hate to air layer it. I think it would weaken it big time. Could you all tell me if General MacArthur is wimpy by nature, or do I need to be more patient for a lead to break from down below? It gets plenty of filtered sun and is in a pretty prime spot. Do I need to get another plant?
