Forgetful with watering? Low light? The ZZ plant shrugs off both. In fact, there's really one reliable way to kill it — and that's overwatering.

Light: the low-light champion

The ZZ plant grows happily in corners where most houseplants struggle — even fluorescent-lit offices with no window at all. It does best in medium, indirect light but never sulks in low light. Just avoid long, direct afternoon sun, which can bleach the glossy leaves. New growth is faster in brighter spots; survival is guaranteed almost anywhere.

Water: dry to the bottom

The ZZ stores water in swollen, potato-like rhizomes under the soil, so it wants to dry out completely between waterings — usually every 2–4 weeks, and even less in winter. When in doubt, wait. The plant tolerates long droughts far better than it tolerates wet feet. Water thoroughly when you do, then let the pot drain.

Soil and pot

Use a well-draining mix — an all-purpose potting soil with a little perlite or coarse grit added works well. Because the rhizomes hate sitting wet, a pot with drainage holes is important. ZZ plants like being snug, so don't rush to upsize.

Yellow leaves are a warning

Yellow stems or leaves on a ZZ almost always mean too much water — the plant's single weakness. If you see it, hold off on watering until the soil is completely dry, and check that the pot isn't holding water at the bottom. Adjust your rhythm: most people water a ZZ about half as often as they think they should. The signs of overwatering post covers this in detail.

Propagating from leaves

You can grow a whole new ZZ from a single leaf: take a clean leaf, plant the cut end in moist soil, and wait — it's slow (months) but it works, and the underground rhizome forms first. For something faster, divide a mature plant at repotting time and pot the sections separately. More methods in our step-by-step propagation guide.

Growth and general care

ZZ plants grow upright and architectural, reaching 60–90 cm indoors, and they rarely need pruning beyond removing an old leaf at the base. They're pest-resistant and happy at normal room temperatures and humidity, making them one of the lowest-maintenance houseplants a beginner can buy.

Toxicity

Like many common houseplants, the ZZ contains calcium oxalate and is toxic to cats and dogs if chewed, so keep it out of reach of pets. See plant toxicity and pets for a full breakdown.
