ZZ plant care

The ZZ plant is a drought-tolerant aroid from eastern and southern Africa. Its thick stems and underground rhizomes store water, so the main risk indoors is too much watering. Give it bright indirect light, let the mix dry out completely before watering, and feed only once or twice a year. It is not on the ASPCA’s plant list; NC State Extension lists it as toxic.

Light

ZZ does best in bright, indirect light and tolerates shade, so it is often chosen for offices and darker rooms. Avoid placing it in strong direct sun: NC State notes that leaves can scald and brown. In low light it grows slowly and may lean toward the window. NC State Extension

Use the indoor light guide to judge a position.

How to check before watering

Water only when the mix has dried out completely. Check down to the lower part of the pot; a dry surface over wet roots is the classic mistake. NC State suggests around once a month in winter and about twice a month in summer, but only when the soil is dry, so treat those as rough limits, not a schedule. NC State Extension

ZZ does not tolerate wet feet. Drain it fully and empty the saucer. See the watering guide for pot-weight checks.

Potting mix and pot

Use a well-drained potting mix and a container with drainage holes. Rhizomes can swell enough to distort a thin plastic pot; that is a sign to move up one size, ideally in spring.

Humidity and temperature

NC State’s profile gives no special humidity requirement, and ordinary room air suits most plants. Keep it warm: if you summer it outdoors in a container, bring it in before temperatures fall below about 16 °C (60 °F). NC State Extension

Feeding

NC State suggests a balanced liquid houseplant fertilizer once or twice a year. More feeding does not compensate for low light. NC State Extension

Common problems

Yellowing stems and mushy bases: often linked to wet mix; check the rhizomes.
Brown, scorched patches: too much direct sun.
Scale insects: NC State notes them as the main pest to watch for.

Read the yellow-leaf checks before acting on one symptom.

Propagation

Divide the rhizomes at repotting time, or root single leaflets or leaf stems in a barely moist mix. Leaf cuttings are slow and can take months to form a new shoot. NC State Extension

Pets and people

ZZ plant does not appear in the toxic and non-toxic plant list of the ASPCA Animal Poison Control Center (checked 22 October 2026). “Not listed” does not mean safe. NC State Extension lists it as toxic, with calcium oxalate in the leaves, and says eating leaves in quantity may cause vomiting and diarrhoea. Keep it out of reach. If a pet chews it, contact a veterinarian or an animal poison control service. For people in Türkiye, the poison information line is 114 (UZEM). This is general information, not veterinary or medical advice.

Common questions

Is it called Zamia?

It is sometimes sold as “Zamia”, but Zamia is a different genus of cycads. The ZZ plant is Zamioculcas zamiifolia.

Can a ZZ plant live in low light?

It tolerates low light but grows slowly. Give it the brightest indirect light you can.

Why are the stems falling over?

Check light first, then the base of the stems for softness caused by wet mix.
