Questions people ask
- Can I prune the leggy stems?
- Yes, you can trim back the long stems to encourage a bushier, more compact growth habit. Use clean scissors to snip just above a leaf node.
- Will the stems fill back in?
- Once a stem has grown thin and leggy, it will not thicken up. Pruning it back will allow new, healthier growth to emerge.
