Calathea zebrina is a stunning and rewarding plant for those who enjoy a challenge. Its lush, patterned leaves bring a touch of the rainforest indoors, making it a centerpiece in any plant collection. With proper attention to humidity, water, and light, it will thrive and remain a captivating addition to your home.
Light
Prefers bright, indirect light but can tolerate lower light conditions.
Avoid direct sunlight, which can scorch the leaves and fade their vibrant patterns.
Ideal for a spot near a filtered or north-facing window.
Water
Keep the soil consistently moist but not soggy.
Water when the top 1-2 inches of soil feel dry.
Use filtered or distilled water, as Calatheas are sensitive to chemicals like chlorine and fluoride in tap water.
Humidity
Thrives in high humidity levels (50-70% or higher).
Mist the plant regularly, use a humidifier, or place it on a pebble tray with water to maintain humidity.
Dry air can cause the leaf edges to brown or curl.
Temperature
Ideal temperature range: 18-27°C.
Avoid temperatures below 15°C and keep it away from cold drafts or hot, dry air from radiators.
Consistent temperatures are key to keeping the plant healthy.
Soil
Use a well-draining, rich potting mix, such as one formulated for tropical plants.
A mix containing peat moss, perlite, and compost works well to retain some moisture while providing good drainage.
Fertilisation
Feed with a balanced, diluted liquid fertiliser every 4 weeks during the growing season (spring and summer).
Do not over-fertilise, as it can cause leaf burn.
Stop feeding during the fall and winter when the plant's growth slows.
Repotting
Repot every 1-2 years or when the plant becomes root-bound.
Choose a pot with good drainage and only slightly larger than the current pot.
Refresh the soil during repotting to ensure adequate nutrients.
Pruning
Trim any yellowing or damaged leaves at the base to keep the plant tidy and healthy.
Regular pruning can help encourage new growth.
Propagation
Propagation is typically done by division during repotting.
Gently separate the plant into smaller clumps, ensuring each division has roots, and plant them in fresh soil.
