How to Grow ZZ Plant
Zamioculcas zamiifolia
The ZZ Plant is one of the most forgiving houseplants available — its thick rhizomes store water, making it highly drought-tolerant and ideal for low-maintenance households. It tolerates low light well but grows faster in bright indirect light. Water only when the soil has dried out completely, and never overwater. Keep above 8°C and it will thrive with minimal attention year-round.
Yearly Lifecycle
Care Essentials
Feed every 4–6 weeks with a balanced liquid fertiliser during spring and summer. No feeding is needed in autumn and winter when the plant is dormant.
Watch For
- Root rot from overwatering (by far the most common problem)
- Scale insects on stems
- Mealybugs in leaf axils
- Spider mites in very dry indoor air

☀️ Light
Tolerates low light; grows best in bright indirect light.
ZZ plant survives in dimly lit corners but grows faster and produces more foliage in bright indirect light. Avoid direct sun, which scorches the glossy leaves.
💧 Watering
Water only when soil is completely dry.
The thick rhizomes store water, making underwatering far safer than overwatering. In summer water every 2–3 weeks; in winter reduce to once a month or less.
🌱 Fertilizing
Feed every 4–6 weeks in spring and summer only.
Use a diluted balanced liquid fertiliser at half the recommended strength. Stop feeding entirely from autumn through winter when the plant is dormant.
✂️ Pruning
Remove yellowed or damaged stems at the base.
ZZ plants need no regular pruning. Simply cut away any yellowed, damaged, or leggy stems cleanly at soil level to keep the plant tidy.
🌿 Humidity
Tolerates average indoor humidity; no misting needed.
ZZ plant adapts well to the dry air of centrally heated homes. Misting is unnecessary and can encourage bacterial leaf spot — humidity above 40% is sufficient.
Growing Tips
Let it dry out
The ZZ plant's rhizomes store water — always allow the soil to dry out completely between waterings. When in doubt, wait another week.
Bright indirect light speeds growth
It survives in low light but grows noticeably faster in a bright spot away from direct sun. Rotating the pot quarterly ensures even growth.
Wipe the leaves
Glossy ZZ leaves collect dust that reduces photosynthesis. Wipe gently with a damp cloth every few weeks to keep them shining.
Repot sparingly
ZZ plants tolerate being slightly pot-bound and are best repotted only when roots are visibly emerging from the drainage holes, typically every 2–3 years.
Pests & Diseases
Pest Scale Insects
Identification: Brown or tan waxy bumps on stems, often mistaken for part of the plant. Sticky honeydew residue may appear below.
- Scrape off manually with a soft toothbrush dipped in soapy water.
- Wipe stems with a cotton pad soaked in diluted neem oil.
- Apply a systemic insecticide containing imidacloprid as a soil drench.
Pest Mealybug
Identification: White cottony clusters in leaf axils and at the base of stems. Leaves may yellow and growth slows.
- Dab individual colonies with a cotton bud soaked in rubbing alcohol.
- Spray the whole plant with insecticidal soap every 7 days for 3–4 weeks.
- Use a systemic insecticide drench — mealybugs are hard to reach with contact sprays.
Pest Spider Mite
Identification: Fine webbing between stems and leaf axils, pale speckled leaf surface. More common in heated rooms in winter.
- Increase humidity around the plant — mites thrive in dry air.
- Spray with diluted neem oil or insecticidal soap weekly until clear.
- Use a miticide spray labelled for indoor plants.
Disease Root Rot Pythium spp. / Phytophthora spp.
Symptoms: Yellowing leaves, soft mushy stems at the base, foul-smelling soil. The plant may collapse suddenly.
Treatment: Remove from pot, cut away all blackened roots, dust with sulphur powder, and repot in fresh well-draining compost. Allow to dry before watering again.
Prevention: Never allow the pot to sit in standing water. Use a pot with drainage holes and a gritty, free-draining compost mix.
Disease Bacterial Leaf Spot Erwinia spp.
Symptoms: Water-soaked brown or black patches on leaves, sometimes with a yellow halo. Spreads in wet conditions.
Treatment: Remove affected leaves immediately. Avoid wetting the foliage when watering. Improve air circulation.
Prevention: Water at the base of the plant and keep foliage dry. Do not mist.
