ZZ Plant Wrinkled Leaves and Stems — Drought Signal or Something More?
ZZ Plant (Zamioculcas zamiifolia)
Symptoms
- wrinkled leaflets
- wrinkled petioles
- soft deflated-looking leaves
- stems losing firmness
- shriveled appearance
Causes
Underwatering — depleted rhizome reserves
ZZ Plants store water in both rhizomes and petioles. When rhizomes are depleted, the plant draws water from the succulent tissue of the petioles themselves. As this cellular water decreases, the petioles wrinkle and lose their characteristic firmness — the plant equivalent of a deflated water balloon. This is the most common cause and the most benign: fix it by watering.
Root rot reducing water uptake
Paradoxically, wrinkled ZZ Plant leaves sometimes indicate overwatering rather than underwatering. When rhizomes rot, the water delivery pathway to the petioles is severed. The plant is surrounded by water in the soil but cannot access it. To distinguish: moist soil + wrinkling = rot is likely. Dry soil + wrinkling = underwatering.
Severe root-bound conditions
When the pot is densely packed with rhizomes and very little soil remains, water drains through the pot so quickly after each watering that the roots cannot absorb enough. The plant shows drought symptoms even with regular watering.
How to Fix It
- 1
Check the soil moisture before acting. Dry soil with wrinkled leaves: water thoroughly and wait 24–48 hours. The wrinkles should diminish as water is absorbed. Moist soil with wrinkled leaves: suspect root rot and unpot to inspect.

For drought-induced wrinkling: submerge the pot for 20–30 minutes if the soil is very dry and water runs off the surface rather than soaking in — ZZ Plant's underground rhizomes store enough of their own reserve that this step is about restocking the soil, not rescuing the plant from imminent damage. Then drain completely.
- 3
For wrinkles that persist after thorough watering even with dry soil: the rhizomes themselves may have simply outgrown their water-storage capacity for the leaf mass they're supporting. Slide the plant out — if you can barely find soil between the swollen rhizome sections — divide or move up a size so the storage organs have room to keep expanding along with the top growth.

For rot-related wrinkling: unpot, remove all rotted rhizome material, let the roots air-dry for 2–4 hours, and repot in completely fresh fast-draining soil. Withhold water for 10 days after repotting.
Prevention
- Judge readiness to water by hefting the pot rather than watching the calendar — the rhizomes' stored reserves mean visible wrinkling is already a late-stage signal, so weight is the earlier tell.
- Repot every 2–3 years to prevent the densely packed root-bound state that causes drought symptoms despite regular watering.
- Use fast-draining soil so that when you do water, the root zone is saturated but not left waterlogged.
