The ZZ plant, scientifically known as Zamioculcas zamiifolia, is a highly favored houseplant recognized for its striking, waxy, dark green foliage. It has earned a reputation for being exceptionally resilient and low-maintenance. Its adaptability makes it a popular selection for both novice plant enthusiasts and those seeking an easy-care indoor plant.
ZZ Plant Care
Light
ZZ plants exhibit versatility regarding light conditions, thriving in environments from low to bright indirect light. They perform best in medium indirect light, which encourages robust growth and vibrant foliage. Shield these plants from direct, intense sunlight, as prolonged exposure can scorch their leaves.
Water
The ZZ plant is exceptionally drought-tolerant, primarily due to its rhizomes, which are underground stems that store water. Allow the soil to completely dry out between waterings. To assess soil moisture, insert a finger several inches deep; if it feels dry, the plant is ready for water. Overwatering is the most frequent cause of problems, often leading to root rot.
Soil
A well-draining potting mix is essential for ZZ plants to prevent waterlogging around their rhizomes. Use a commercial potting mix formulated for cacti or succulents to ensure drainage. Alternatively, a standard indoor potting mix can be amended with perlite or pumice for aeration and drainage.
Temperature and Humidity
ZZ plants prefer average indoor temperatures, thriving between 65-75°F (18-24°C). They are sensitive to cold drafts and should not be exposed to temperatures below 50°F (10°C), which can cause damage. While they appreciate consistent warmth, ZZ plants tolerate average household humidity.
Fertilizer
ZZ plants are not heavy feeders and require minimal fertilization. Apply a balanced liquid houseplant fertilizer diluted to half strength once or twice during the active growing season. Over-fertilization harms the plant, and many ZZ plants flourish without a feeding schedule.
Common Issues
Yellowing leaves on a ZZ plant often indicate overwatering and root rot. Reducing the watering frequency and checking the plant’s rhizomes for any mushy texture addresses this. If stems or leaves begin to droop, it suggests either severe underwatering or, more frequently, root rot from excessive moisture. Inspecting both the soil and roots differentiates the cause.
Leggy growth, characterized by elongated stems with sparse foliage, signals insufficient light. Moving the plant to a brighter location with more indirect light encourages more compact and robust growth. ZZ plants are resistant to pests, but common houseplant pests like spider mites or mealybugs can appear. Wiping the leaves with a damp cloth or using insecticidal soap manages these infestations.
