Water

ZZ Plants are drought-tolerant and prefer to be kept on the drier side. Water only when the top inch of soil is dry to the touch, and be sure to avoid overwatering as this can lead to root rot. ZZ Plants are also sensitive to fluoride, so it's best to use distilled or filtered water to avoid any potential damage to the leaves.

Light

ZZ Plants can tolerate a range of light conditions, from low to bright indirect light. However, they prefer bright, indirect light and will grow best in these conditions. Avoid placing ZZ Plants in direct sunlight, as this can scorch their leaves.

Fertilizer

ZZ Plants do not require frequent fertilization and can thrive without it. However, if you want to encourage growth and keep your plant looking healthy, you can fertilize once a month during the growing season (spring and summer) with a balanced houseplant fertilizer.

Humidity & Temperature

ZZ Plants are adaptable to a range of humidity and temperature levels. They can tolerate low humidity and temperatures between 60-75°F (16-24°C). However, they do prefer slightly higher humidity levels, so misting or placing a humidifier near the plant can help to promote healthy growth.

Repotting

ZZ Plants prefer to be slightly root-bound and do not require frequent repotting. Repotting every 2-3 years or when the plant has outgrown its current container is sufficient. Use a well-draining potting mix and a container with drainage holes to prevent water from accumulating in the soil.

Propagating

ZZ Plants can be propagated by dividing the rhizomes (thick, underground stems) during repotting or by leaf cuttings. To propagate from leaf cuttings, simply cut a leaf from the plant and allow it to dry for a few days before placing it in a pot with well-draining soil. Keep the soil moist and warm, and new growth should appear within a few weeks.

Pests

ZZ Plants are relatively pest-free, but they can occasionally attract mealybugs or spider mites. Check the leaves regularly for any signs of infestation, such as white or brown spots, and treat with an insecticidal soap if necessary.

Varieties

There are several varieties of ZZ Plant, including 'Zamicro', a dwarf variety that stays small and compact, and 'Raven', a variety with dark purple leaves. There is also a variegated variety called ‘Variegata’, which has cream-colored stripes on the leaves, either white or yellow. Other varieties include ‘Lucky Classic’, ‘Lucky Giant’, ‘Zenzi’ and ‘Super Nova’.

Fun Facts

ZZ Plants are sometimes called "eternity plants" because of their ability to survive in harsh conditions and neglect. They are also known for their air-purifying qualities, as they can remove toxins such as formaldehyde and benzene from the air. ZZ Plants are a common feature in interior design, as they can add a modern and minimalist touch to any space. Zamioculus zamiifolia are native to Eastern Africa, specifically Tanzania and Zanzibar. They are considered toxic to pets and humans if ingested. They contain calcium oxalate crystals which can cause irritation and swelling of the mouth, tongue, and throat if chewed or eaten. ZZ Plants are a versatile and easy-to-care-for houseplant that can thrive in a variety of conditions. With proper care and attention, your ZZ Plant can provide you with years of beauty and enjoyment.
