Cutting back a ponytail palm involves removing excess foliage to maintain its shape and health. It’s important to use sharp pruning shears to cleanly cut leaves at the base, avoiding tearing or damaging the plant. Trimming should be done during the active growing season, typically in the spring or summer. Avoid over-trimming, as the plant needs its leaves for photosynthesis and growth. Additionally, remove any dead or diseased leaves promptly to prevent spread and encourage new growth.
