ZZ plant care guide
Zamioculcas zamiifolia
Also known as: Zanzibar gem, Eternity plant
Pets and children
Considered toxic
All parts contain calcium oxalate; chewing causes mouth pain, swelling, and vomiting, and the sap can irritate skin, so keep it out of reach and consult a veterinarian, or a doctor for a child, if eaten.
How often to water ZZ plant
- Spring–Summer (Mar–Sep)
- Every 10 days
- As a guide, water thoroughly only after the soil has dried through; the tubers at the base store water, so about every ten days to two weeks is enough.
- Autumn (Oct–Nov)
- Every 2 weeks
- Generally wait about a week after the soil dries before watering; growth stops as the days shorten.
- Winter (Dec–Feb)
- Every month
- About once a month, just barely moisten the soil; it survives almost dry, and overwatering, not drought, is what rots it.
Light and placement for ZZ plant
Bright shade generally suits it, and it tolerates a room lit only by ceiling lights; direct sun scorches the leaves, and deep shade makes new shoots lanky.
Overwintering ZZ plant
Overwintering guide: 8°C (46°F) or above
Overwinter it indoors above roughly 8°C; kept on the dry side it takes the cold better, and it should not sit directly on a cold floor.
Fertilizing and repotting ZZ plant
Fertilizer
Slow-release fertilizer about every two to three months from May to September is usually enough; it needs little feeding and none in winter.
When to repot
Spring–Summer (Mar–Sep)
Common problems with ZZ plant
- Watered as often as other houseplants, the tubers rot and the leaves yellow.
- Standing water in the saucer rots the roots and the stems topple at the base.
- In a dark spot new shoots grow thin and the leaflets space out.
Tips for growing ZZ plant
- Lift the pot and water only when it feels light; that alone prevents most trouble.
- It grows slowly, so repotting about every two to three years is enough.
- A single leaf pushed into soil will root, though it takes several months.
These are AI-generated general guidelines. They vary with the variety, the placement and the pot size. For effects on pets or children, consult a veterinarian or a doctor.
