How often should I water a ZZ plant?

Only every 2 to 4 weeks, and only when the soil is completely dry. ZZ plants store water in thick underground rhizomes, so they handle drought easily and rot quickly if kept wet. Check that the soil is dry all the way down before watering, then water thoroughly and let it drain. In low light and winter they need water even less often, sometimes just once a month. When in doubt, wait, because a ZZ plant tolerates being too dry far better than being too wet.

Can a ZZ plant survive in low light?

Yes, ZZ plants are one of the best true low-light houseplants, thriving in dim offices and rooms with only artificial light. They grow more slowly in low light and stretch a little toward the nearest source, but they stay healthy. They grow best in bright, indirect light, which is worth providing if you can, but they never need it. Just keep them out of harsh direct sun, which can scorch the glossy leaves. This tolerance is why they are a top pick for windowless spaces.

Why is my ZZ plant turning yellow?

Yellowing on a ZZ plant almost always means overwatering. Because it stores so much water, it needs very little, and soggy soil quickly rots the rhizomes, which shows as yellowing, soft stems and mushy roots. Stop watering, let the soil dry out completely, and check the rhizomes if the base is soft, cutting away any that are brown and mushy. An occasional single old yellow leaf is normal, but multiple yellowing stalks signal that you are watering too often.

Is the ZZ plant poisonous?

Yes, ZZ plants are mildly toxic to people and pets if eaten, because all parts contain calcium oxalate crystals that irritate the mouth, throat, and stomach and can cause drooling and vomiting. The sap can also irritate skin, so it is worth washing your hands after pruning or repotting. The plant is not usually dangerous in small amounts, but keep it out of reach of pets and small children who might chew it, and contact a vet or doctor if a significant amount is eaten.

How fast do ZZ plants grow, and how do I propagate one?

ZZ plants are slow growers, especially in low light, often producing only a few new stalks a year, so patience is part of owning one. You can propagate them by division at repotting time, separating the rhizome clump into sections each with roots and stalks, or from leaf cuttings rooted in soil or water. Leaf cuttings are very slow, taking many months to form a new rhizome, but they work. Division is faster and gives you an established plant immediately.

The short answer: the ZZ plant is about as low-maintenance as houseplants get. Give it low to bright indirect light (it tolerates dim rooms), water it only when the soil is fully dry, roughly every 2 to 4 weeks, plant it in well-draining soil in a pot with drainage, keep it in normal room temperatures of 65 to 80 F, and feed it lightly a couple of times a year. It survives neglect, drought, and dark corners. The one way to kill it is to overwater.

ZZ plants (Zamioculcas zamiifolia) are glossy, upright plants from East Africa that store water in thick underground rhizomes, making them exceptionally drought-tolerant. They are the plant to choose for a dim office, a forgetful owner, or a spot nothing else will grow. Our guidance reflects horticultural consensus rather than first-hand lab testing, as explained in how we rank.

Light for a ZZ plant

ZZ plants are prized for handling a wide range of light, especially the low end.

Best: bright, indirect light, where they grow fastest and fullest.
Tolerated: low light, including dim offices and rooms lit only by artificial light. They stay healthy, just grow more slowly and may stretch slightly.
Avoid: harsh, direct sun through glass, which can scorch and yellow the glossy leaflets.

This genuine low-light tolerance makes the ZZ one of the best plants for dark corners; see more in low-light houseplants. If you want faster growth in a dim room, a modest grow light helps.

Watering a ZZ plant

Watering is the one thing that matters, and the rule is to water rarely.

Water only when the soil is completely dry, typically every 2 to 4 weeks, and less in low light or winter.
Water thoroughly until it drains from the bottom, then empty the saucer and let the soil dry out fully again.
Never let it sit in water. The rhizomes rot fast in soggy soil.
When in doubt, wait. A ZZ plant handles being too dry far better than being too wet.

Because it stores so much water underground, the ZZ is one of the most drought-proof houseplants and a strong choice for travelers. Detailed timing is in how often to water a ZZ plant.

Soil and pots

Fast drainage protects the water-storing rhizomes.

Use a well-draining mix, such as a standard houseplant mix with added perlite, or a cactus and succulent blend.
Choose a pot with a drainage hole. Terracotta helps by drying faster.
Do not over-pot. ZZ plants are slow growers happy to be a little snug; repot only every 2 to 3 years when the rhizomes crowd the pot.

See suitable blends in our potting mix for succulents guide, most of which suit ZZ plants well.

Temperature and humidity

ZZ plants are content in ordinary indoor conditions.

Temperature: best between 65 and 80 F. Keep them above 45 F and away from cold drafts.
Humidity: average household humidity is fine; they do not need extra and never need misting.
Placement: keep them clear of hot or cold vents.

Feeding a ZZ plant

ZZ plants are very light feeders.

Feed once or twice during spring and summer with a balanced houseplant fertilizer at half strength.
Skip feeding in fall and winter.
Do not overfeed. This slow grower needs little, and excess fertilizer causes leaf burn and salt buildup.

Gentle options are in our best indoor plant fertilizer picks.

Grooming, repotting, and propagation

A ZZ plant needs almost no upkeep.

Dust the leaves occasionally with a damp cloth to keep their signature shine and help them photosynthesize.
Remove any yellow or damaged stalks at the base.
Repot every 2 to 3 years in spring, moving up one pot size. The rhizomes are strong enough to crack a pot when badly overcrowded.
Propagate by division at repotting time for an instant new plant, or by slow leaf cuttings. Full detail is in how to propagate a ZZ plant.

Growth rate, size, and lifespan

Setting the right expectations makes a ZZ plant far more satisfying to own, because its slow pace is normal, not a fault.

Slow but steady: ZZ plants add only a handful of new stalks a year, more in bright light and almost none in deep shade. A plant that looks unchanged for months is behaving exactly as it should.
Ultimate size: indoors they typically reach 2 to 3 feet tall and wide over several years, forming a full clump of arching stalks. There is no need to rush repotting to make it bigger.
New growth quirk: fresh stalks emerge bright, almost lime green and stand very upright before darkening and arching outward. This pale new growth is healthy, not a sign of a problem.
Long-lived: given its few simple needs, a ZZ plant easily lasts many years and only improves as it fills out, which makes it a strong value for a low-effort plant.

Varieties and the raven ZZ

A couple of distinct varieties are widely sold, and they share the same easy care.

Classic ZZ: the standard glossy green form, the toughest and most shade-tolerant.
Raven ZZ: a striking cultivar whose new growth emerges bright green and matures to near-black, giving a two-tone look. It grows a touch slower and appreciates a little more light to develop its dark color, but otherwise wants identical care.
Variegated ZZ: rarer and more expensive, with cream or yellow marbling. Like all variegated plants, it needs brighter indirect light to hold its markings and grows slower still.

Whichever you own, the care is the same: bright to low light, water only when fully dry, and a fast-draining mix.

Common ZZ plant problems

Symptom	Likely cause	Fix
Yellowing stalks and leaves	Overwatering, rhizome rot	Stop watering, dry out, check and trim rhizomes
Wrinkled stalks, dry soil	Underwatering (rare)	Water thoroughly once; recovery is slow but reliable
Brown leaf tips	Over-fertilizing or inconsistent watering	Flush the soil, ease off feeding, water only when dry
Leggy, stretched stalks	Very low light	Move to brighter indirect light
Scorched or bleached leaves	Direct sun	Move out of harsh direct light

The ZZ plant is close to the ultimate set-and-forget houseplant: glossy, architectural, and almost impossible to kill unless you love it with too much water. Pair it with a snake plant and a pothos and you have a trio that survives almost any home. For its equally easygoing relatives, see how to care for a snake plant.
