Pruning a Snake Plant in a Terrarium

Snake plant (Sansevieria) leaves are the entire plant—cutting a leaf doesn't trigger regrowth from that point. You can trim a tall leaf to a pointed tip for aesthetics; the cut edge may brown slightly as it seals.

Long-Term Solution

Snake plants produce basal pups (sprouts). Remove one, root it in a small pot, and let it replace the mother plant when it outgrows the terrarium. This preserves the gecko's favorite perch while managing size.
