This ZZ plant care guide starts with the short answer: ZZ plant care is simple. Give it bright indirect light (it also tolerates low light), plant it in a free-draining mix in a pot with drainage holes, and water only when the soil has dried out completely, usually every 2–3 weeks in summer and about once a month in winter. Keep it at normal room temperature, feed lightly in spring and summer, and keep it out of reach of pets, because it is toxic if eaten. This applies to every ZZ plant variety, from the classic green form to ‘Raven’.
The ZZ plant (Zamioculcas zamiifolia) has glossy, upright stems, copes with dim rooms and dry air, and forgives forgotten waterings. That is why it is one of the most popular houseplants for beginners, offices and darker homes. This ZZ plant care guide covers its varieties, light, watering, soil, feeding, repotting, propagation, toxicity and how to fix common problems such as yellow leaves.
At Patch Plants, botanist Sawera Shahid often says the ZZ plant is easiest to understand from below the soil: its swollen rhizomes are water stores, which is why the plant prefers to be forgotten rather than fussed over. Read more about how we write our guides on the About Patch Plants page. If you want a quick, tip-by-tip version, see our 11 easy Zamioculcas zamiifolia care tips.
Key Takeaways
- ZZ plants store water in underground rhizomes, so overwatering is the main cause of problems.
- Water only when the soil is completely dry: roughly every 2–3 weeks in summer and monthly in winter.
- Bright indirect light gives the best growth; low light is tolerated but growth slows.
- Use a free-draining mix and a pot with drainage holes, only slightly bigger than the root ball.
- ‘Raven’ and other varieties need the same care; dark and variegated types colour best in brighter light.
- Division is the fastest way to propagate; stem and leaf cuttings work but take months.
- ZZ plants contain calcium oxalate and are toxic to cats, dogs and people if eaten.

What Is a ZZ Plant?
Zamioculcas zamiifolia is a member of the arum family (Araceae), native to eastern and southern Africa, from Kenya and Tanzania to Mozambique, Zimbabwe and KwaZulu-Natal. According to NC State Extension, it is drought tolerant, copes with very low light including fluorescent light, does best in bright indirect light, and does not tolerate wet feet.
The key to its toughness is underground: thick, potato-like rhizomes store water and food so the plant can survive long dry seasons. Each “stem” you see is actually a single compound leaf, with a thick base and rows of glossy leaflets. New stems emerge pale lime green and darken as they mature, which is normal.
ZZ Plant Varieties
All ZZ plant varieties need the same basic care. The main difference is that darker and variegated types keep their best colour in brighter indirect light.
| Variety | Look | Notes |
|---|---|---|
| Standard ZZ | Glossy mid to dark green leaflets | The most common and most tolerant of low light |
| ‘Raven’ (often sold as Black Raven ZZ) | New growth lime green, maturing to purple-black | Introduced around 2018–2019; colours darkest in bright indirect light |
| ‘Zenzi’ | Compact, with tightly packed, slightly curled leaflets | Good for desks and small spaces |
| ‘Chameleon’ | Yellow-gold new growth that turns green with age | Less common; slower-growing |
| Variegated types | Green leaves with cream or white patches | Rare and slower; need brighter light |
Raven ZZ plant care is the same as for the standard form. If new Raven stems stay green for longer than a few weeks, the plant probably needs more light. For other dramatic foliage, see our guide to colorful foliage plants.
ZZ Plant Light Requirements
ZZ plants grow best in bright indirect light, such as near an east-facing window or a little back from a south- or west-facing one. They tolerate low light and office lighting better than almost any other houseplant, but growth becomes very slow and stems may lean toward the light.
- Bright indirect light: best growth, more new stems, darkest colour on ‘Raven’.
- Low or artificial light: survives well, grows slowly; water much less often.
- Strong direct sun: can scorch and yellow the leaflets.
If you have very little natural light, a simple LED grow light helps; see our guide to grow lights for indoor plants, along with our complete guide to indoor light.
How to Water a ZZ Plant
Watering is the one part of ZZ plant care you must get right. Because the rhizomes store water, the soil should dry out completely between waterings.
- Check: push a wooden skewer or your finger deep into the pot. If any moisture remains, wait.
- Water deeply: when it is dry all the way through, water until it drains from the bottom.
- Drain: empty the saucer or decorative pot after 10–15 minutes.
NC State Extension suggests watering about twice a month in summer, only once the soil is completely dry, and about once a month in winter. In low light or cool rooms, you may need to water even less.
| Overwatering signs | Underwatering signs |
|---|---|
| Yellow leaflets and stems, starting low | Wrinkled or shrivelled stems and leaflets |
| Soft, mushy stem bases | Leaflets curling or dropping after weeks of dry soil |
| Soil still damp a week after watering; sour smell | Soil pulling away from the pot |
Underwatering is rare and easy to fix with a thorough drink; overwatering is far more common and harder to reverse. See our signs of overwatering guide and complete watering guide.
Best Soil and Pot for a ZZ Plant
Use a free-draining mix that holds a little moisture but lets air reach the rhizomes, for example:
- about 60% houseplant potting mix,
- about 30% perlite or pumice,
- about 10% fine orchid bark.
A cactus and succulent mix blended with some regular potting mix also works. Always use a pot with drainage holes. Terracotta dries faster and is forgiving, while plastic holds moisture longer; ZZ rhizomes can crack thin plastic pots as they grow. Our best soil mix guide has more recipes.
Temperature and Humidity
Normal room temperatures of 18–26°C (65–80°F) suit ZZ plants. Keep them above about 13–15°C (55–60°F) and away from cold draughts, single-glazed windows in winter and direct blasts from heaters or air conditioning. NC State notes that container plants put outside for summer should come back in once temperatures fall below about 15°C (60°F). Average household humidity is fine; misting isn’t needed.
Fertilizing a ZZ Plant
ZZ plants are light feeders. Use a balanced liquid houseplant fertilizer at half strength every 4–6 weeks in spring and summer, and stop in autumn and winter. Overfeeding causes brown tips and salt build-up. See our guide to fertilizing indoor vs outdoor plants.
When and How to Repot a ZZ Plant
Repot every two to three years in spring, or when rhizomes are pushing against or distorting the pot, roots grow out of the drainage holes, or the plant becomes top-heavy. ZZ plants grow well when slightly snug, so choose a pot only 2–5 cm wider.
- Water a few days before, so the root ball is lightly moist rather than wet.
- Slide the plant out; if the pot is stuck, cut a plastic nursery pot away.
- Check that rhizomes are firm and pale; cut out any soft, dark or smelly parts with clean scissors.
- Replant at the same depth in fresh, free-draining mix and water once.
- Wait until the mix dries completely before watering again.
See our guides on how to repot a plant and repotting mistakes to avoid.
How to Propagate a ZZ Plant
| Method | How to do it | Time |
|---|---|---|
| Division (fastest) | When repotting, separate a clump with its own rhizome, roots and stems; pot it in fresh mix | Instant new plant |
| Stem cuttings | Cut a whole stem at the base; root it in water or moist, gritty mix in bright indirect light | Roots in weeks; new shoots often take several months |
| Leaf cuttings | Push single leaflets, cut end down, into moist gritty mix | A small rhizome forms over several months |
Keep cuttings warm (around 20–25°C) and only lightly moist; too much water rots them. Our step-by-step propagation guide explains each method.
Do ZZ Plants Flower?
Yes, but rarely indoors. Mature, well-grown plants sometimes produce a small, cream to pale green spathe and spadix, typical of the arum family, near the base of the stems. The flowers are not showy and can be left or removed. They are more likely on older plants in good light.
Is the ZZ Plant Toxic to Cats and Dogs?
Yes. ZZ plants contain calcium oxalate crystals. NC State Extension rates their toxicity as medium for cats and dogs: chewing or eating the leaves can cause mouth irritation, drooling, vomiting and diarrhoea. Serious poisoning is uncommon, but contact your vet if a pet eats any part of the plant or symptoms persist.
- Keep ZZ plants on high shelves or in rooms pets can’t reach.
- Wear gloves when pruning or dividing, and wash your hands afterwards.
- Pick up fallen leaves and cuttings promptly.
For pet-safe alternatives, see our cat-friendly plants guide and dog-friendly plants guide.
Why Are My ZZ Plant Leaves Turning Yellow?
- Overwatering (most common): several stems yellowing, damp soil, sometimes soft stem bases. Let the soil dry completely and check the rhizomes.
- Root or rhizome rot: soft, dark, smelly rhizomes. Unpot, cut away the rot and replant in fresh, dry mix.
- Natural ageing: one old stem yellowing slowly while new growth is healthy. Cut it off at the base.
- Too much direct sun: pale, bleached or yellow patches on the side facing the window.
- Cold damage: yellowing or darkened leaflets after a cold draught.
Our guides to why leaves turn yellow and root rot go into more detail.
ZZ Plant Problems and Fixes
| Problem | Likely cause | Fix |
|---|---|---|
| Yellow stems, damp soil | Overwatering | Water less; improve drainage |
| Mushy stems or rhizomes | Rot | Remove rotten parts; repot in fresh mix |
| Wrinkled stems | Long-term underwatering | Water thoroughly |
| Leaning, stretched stems | Low light | Move to brighter indirect light; stake if needed |
| Brown tips or crispy patches | Direct sun, cold or fertilizer salts | Move the plant, flush the soil, feed less |
| No new growth | Low light, winter, cramped or exhausted mix | More light in spring; repot if crowded |
| Sticky leaves, white fluff, webbing | Scale, mealybugs or spider mites | Wipe off pests; use insecticidal soap |

Where to Display a ZZ Plant
- Living room: a mature ZZ in a tall pot makes a sculptural floor plant beside a bright window.
- Home office: it handles artificial light and irregular watering; see our guides to office plants that survive fluorescent lighting and improving your home office with plants.
- Bedroom: low care and happy in moderate light; see our bedroom plant ideas.
- Hallways and darker corners: one of the few plants that copes, as long as it gets some daylight or a lamp.
- With other plants: pair it with a snake plant or pothos, which share its easy-going needs.
Wipe the glossy leaves with a damp cloth every few weeks to remove dust; avoid leaf-shine products. See how to clean plant leaves. For more styling ideas, read how to style indoor plants by room.
Does a ZZ Plant Purify the Air?
ZZ plants are often listed as air-purifying, but research shows that a few houseplants have only a very small effect on air quality in a real home compared with ventilation. Grow a ZZ plant because it is beautiful and easy, not as an air purifier. Our guide to air-purifying plants explains the evidence.
How to Grow a Big ZZ Plant
A ZZ plant grows slowly, but with good conditions it can reach 90 cm or more over several years. To encourage a fuller, larger plant:
- give it the brightest indirect light you have, or a grow light in winter,
- feed at half strength every 4–6 weeks in spring and summer,
- let it fill its pot before moving up just one size, and
- repot into fresh mix every two to three years.
For displaying large plants, see our guides to creating an indoor jungle without overcrowding and the best indoor plants for beginners.
Frequently Asked Questions
How often should you water a ZZ plant?
Only when the soil is completely dry, usually every 2–3 weeks in spring and summer and about once a month in winter. Low light, cool rooms and large pots all mean watering less often.
Why is my ZZ plant turning yellow?
Overwatering is the most common cause. Let the soil dry fully, check that the pot drains and look for soft rhizomes. A single old stem yellowing slowly while new growth looks healthy is normal ageing.
Can a ZZ plant live in low light?
Yes. It tolerates low and artificial light better than most houseplants, although it grows slowly there. In low light, water even less often because the soil dries more slowly.
Is a ZZ plant toxic to cats and dogs?
Yes. It contains calcium oxalate crystals, which can cause mouth irritation, drooling, vomiting and diarrhoea if chewed or eaten. Keep it out of reach and contact your vet if your pet eats it.
How do I care for a Raven ZZ plant?
Exactly like a standard ZZ plant, but give it bright indirect light so its new lime-green stems darken to purple-black. Water only when the soil is completely dry and use a free-draining mix.
Final Thoughts
If there is one lesson from this ZZ plant care guide, it is that the ZZ plant rewards a light touch. Give it bright indirect light, a well-drained pot and an airy mix, then water only when the soil is completely dry. Whether you grow the classic green form, a dramatic ‘Raven’ or a compact ‘Zenzi’, the same simple routine keeps it glossy and healthy for years.
