Calathea Ornata Care
Ideal Growing Conditions
Light
The Calathea ornata thrives in bright, indirect light. Direct sunlight can scorch the leaves, causing the colors to fade or the edges to brown. The best location for the plant to receive filtered light is next to a window that faces either north or east. If natural light is insufficient, fluorescent lighting can also support its growth.
Temperature
This tropical plant prefers warm temperatures between 18-24°C (65-75°F). It is sensitive to cold drafts and sudden temperature changes, so avoid placing it near windows or doors that open frequently during the winter. The Calathea ornata does well in a stable environment where the temperature does not drop below 15°C (60°F).
Humidity
High humidity is crucial for the Calathea ornata. It flourishes in environments with humidity levels of 60% or higher. To maintain this, you can place a humidifier nearby, mist the plant regularly, or place the pot on a tray filled with pebbles and water. Low humidity can cause the leaves to curl and the edges to brown.
Soil
The pinstripe plant prefers a well-draining potting mix that retains moisture without becoming waterlogged. A mix of peat, perlite, and orchid bark provides the right balance of drainage and moisture retention. The soil should be kept consistently moist but not soggy, as overwatering can lead to root rot.
Watering
Water the Calathea ornata with filtered or distilled water, as it is sensitive to fluoride and chlorine commonly found in tap water. It’s important to keep the soil uniformly damp but not soggy. When the top inch of soil is completely dry to the touch, water the area well. As the plant’s growth slows down throughout the winter, watering should be done less frequently.
Fertilization
Feed your Calathea ornata every four weeks during the growing season (spring and summer) with a balanced, water-soluble fertilizer diluted to half strength. Avoid fertilizing in the fall and winter, as the plant’s growth naturally slows during these periods.
Common Problems and Solutions
-
Browning leaf edges:
Browning edges can result from low humidity, overfertilization, or water quality. Increase humidity, reduce fertilizer application, and use filtered water to mitigate this issue.
-
Leaf Curling:
Curling leaves often indicate that the plant is too dry, either due to low humidity or underwatering. Increase watering frequency and humidity levels to help the leaves return to their natural state.
- Pests:
The Calathea ornata can be susceptible to spider mites, aphids, and mealybugs. Regularly check the plant and treat any pests with insecticidal soap or neem oil.
Propagation
The Calathea ornata can be propagated through division. The best time to do this is during the plant’s active growing season in the spring. Carefully separate the plant at the roots, ensuring each division has at least one healthy stem and a few leaves. Plant each division in fresh, moist soil, and keep it in a warm, humid environment to encourage new growth.
The Calathea Ornata, with its exquisite striped foliage and unique movement, is a captivating addition to any indoor plant collection. While it may require a bit more attention compared to other houseplants, the rewards are well worth the effort. By providing the right care, you can enjoy the vibrant beauty of this pinstripe plant and create a lush, tropical atmosphere in your home.
