Questions people ask
- Should I prune the leggy stems?
- You can trim back very long stems to encourage a bushier shape. Use clean scissors and cut just above a leaf node.
- Can I fix leggy growth by moving it?
- Moving it to better light will stop new growth from being leggy. However, the existing long stems will not shrink back to their original size.
