How to Prune ZZ Plant
When is the best time to prune?
ZZ plants grow slowly year-round but are most active in spring and summer, so pruning during the warm months gives the rhizomes the best chance to push out replacement stems.
Why Should I Prune My ZZ Plant?
ZZ plants are famously low-maintenance, and most of the time they don't need pruning at all. But occasionally a stem turns yellow, gets damaged, or grows so long it flops over, and that's when a quick trim helps.
Each ZZ stem grows directly from an underground rhizome. When you cut a stem, you're removing it permanently since it won't sprout new leaves from the stub. Cut yellowing or unwanted stems all the way down at soil level using clean pruners.
If your ZZ plant has gotten lopsided, you can remove a few of the longest stems to balance the shape. But keep in mind that new stems take months to emerge, so the plant will look thinner for a while. It's better to rotate the pot for even light exposure than to rely on pruning for symmetry.
The one thing to be careful about is the sap. ZZ plant sap contains calcium oxalate crystals that can irritate your skin. Wear gloves when pruning and wash your hands afterward.
