Calathea Orbifolia

Calathea orbifolia, commonly known as the round-leaf prayer plant, is celebrated for its striking foliage and unique leaf shape. Here’s a detailed overview of this beautiful plant:

Description

• Leaves: Calathea orbifolia features large, round, and velvety leaves that can grow up to 12 inches (30 cm) in diameter. The leaves are bright green with distinctive lighter green or silver stripes running parallel to the leaf veins, giving them a dramatic appearance.
• Growth Habit: This plant has a clumping growth habit and typically reaches heights of 2-3 feet (60-90 cm), making it an eye-catching addition to any indoor garden.

Care Tips

• Light: Calathea orbifolia prefers bright, indirect light. While it can tolerate low light, insufficient light may result in slower growth and less vibrant leaves. Avoid direct sunlight, which can scorch the leaves.
• Watering: Keep the soil consistently moist but not soggy. Water when the top inch of soil feels dry. Calathea is sensitive to chlorine and hard minerals, so using distilled or rainwater is ideal.
• Humidity: This plant thrives in high humidity (50% or higher). If your home is dry, consider misting the leaves regularly, using a pebble tray, or placing a humidifier nearby.
• Temperature: Ideal temperatures range from 65-80°F (18-27°C). Protect from cold drafts and sudden temperature changes.

Potting and Soil

• Medium: Use a well-draining potting mix that retains moisture, such as a mix formulated for tropical plants. A combination of potting soil, peat moss, and perlite works well.
• Repotting: Repot every 1-2 years or when the plant becomes root-bound, preferably in the spring.

Fertilization

• Schedule: Fertilize with a balanced, diluted liquid fertilizer every 4-6 weeks during the growing season (spring and summer). Reduce feeding in the fall and winter.
• Dilution: Always dilute the fertilizer to half-strength to avoid over-fertilizing.

Pests and Problems

• Common Pests: Calathea orbifolia can be susceptible to pests like spider mites, aphids, and mealybugs. Regularly check the undersides of leaves and keep them clean to prevent infestations.
• Leaf Issues: Yellowing leaves may indicate overwatering, while browning leaf edges can signal low humidity. Ensuring proper watering and humidity levels is key to keeping this plant healthy.
