Growing multiple trunks on a ponytail palm isn't too difficult All you'll need to do is repot your palm annually. The process involves removing the old potting mix from around the trunk and replacing it with new potting mixture. Then, place the palm back inside the container. Afterward, fill up the hole with additional soil until the topsoil level reaches the rim of the pot. Finally, use a pencil eraser to smooth down the surface of the soil. Do this again next spring.
