ðą How to Care for ZZ Plant to Prevent Fungus Gnats?
ð§ How to Water
Water only when the top 2-3 inches of soil are completely dry, typically every 2-3 weeks. Reduce watering in winter. The plant stores water in its rhizomes, making it highly drought-tolerant. Overwatering causes root rot - when in doubt, wait before watering.
âïļ Lighting
Thrives in low to bright indirect light. Tolerates low light conditions well, making it ideal for offices and north-facing windows. Avoid direct sunlight which can scorch the leaves. Grows well under fluorescent lighting.
ðŠī Ideal Soil
Use a well-draining potting mix, similar to cactus soil. A mix of potting soil, perlite, and coarse sand works well. Ensure the pot has drainage holes. Slightly acidic to neutral pH (6.0-7.0) is ideal.
