Your zebra plant thrives in bright, indirect light. It can tolerate a couple of hours of direct morning sunlight, but avoid long periods of direct sun and especially direct afternoon sun, which can cause the leaves to scorch. Zebra plants are not adaptable to low light.
Water your zebra plant when the top 25% of soil is dry. Water thoroughly, and be sure to empty the saucer of any excess water to prevent root rot. Avoid watering directly on the leaves, as water can funnel down the stems and cause crown rot.
Your zebra plant requires a high humidity level of 60-70%. In lower humidity environments, the leaf edges will brown, new leaves may not develop properly, and the plant will not thrive. Group plants together to create a humid microclimate, place a humidifier nearby, or use a pebble tray to raise the humidity. Keep the plant away from air vents, which can be drying. A large humidity dome with a vent may be helpful.
Your zebra plant prefers temperatures at 65°F and above to thrive. Avoid cold drafts and sudden temperature changes.
For best results, use a liquid houseplant fertilizer diluted to half the recommended strength once every 1-2 weeks during the spring and summer. Never apply fertilizer to dry soil; always make sure the soil is damp before feeding your plant.
Your zebra plant is considered to be non-toxic to pets and humans.
