I have a ponytail palm that is taller than my home. It has 5 shoots growing out the sides of the main trunk, but they are not growing out the the bulb on the bottom. Can these shoots be cut off and rooted to make new plants?
It sounds as if the new shoots were pups at one point and when they were not removed, just continued to grow up the plant.
Removing could leave the plant open to disease and insects.
Much would depend on the size of these shoots and the heath of the plant.
