Q.My Yucca appears to have 5/6 plants on the same stalk
Old leaves are in the middle. Young new leaves on the outside. I want to keep the plant about the same size which means pruning. Do I take out the old leaves? What is your suggestion, please?

If the plant is growing too tall, you can cut the top part and root it somewhere else. Or you can cut off some of the offshoots and root them. Here's an article about that: https://www.gardeningknowhow.com/ornamental/foliage/yucca/propagation-of-yucca-plant.htm
