Q.pygmy palms
I have a pygmy palm tree in the front of my house. It is a beautiful specimen; however, it is beginning to grow “Leggy” or taller than I anticipated. Is there a way I can curtail or discourage the palm from growing taller? Can I prune the top to force it to grow outwards instead of upwards?

Pruning should be limited to removing yellowing, diseased or damaged fronds. Over pruning can lead to the decline or death of the palm.
