Wait until the potting medium has dried between waterings. NCSU says to allow the soil to dry completely, while Iowa describes drying before the next thorough watering.

When to water
Water less often in winter. NCSU gives about once monthly in winter and about twice monthly in summer only when dry, while Iowa places active watering and feeding in spring and summer.
How to water thoroughly
- When the medium is dry, water thoroughly until excess exits the drainage holes, then empty the saucer or cachepot instead of leaving roots in drained water.
- Use a container and medium that drain freely. NCSU warns that ZZ plants do not tolerate wet feet and RHS specifies a well-drained indoor medium.
Signs of too much or too little water
Soil that stays wet, yellowing or soft growth should trigger a drainage and moisture check before another watering. Dry, wrinkled growth should trigger the same check rather than an automatic schedule.
