Calatheas are striking plants, admired for their intricate leaf patterns and vibrant colors. Known for their unique nyctinastic movement, which is them folding leaves upward at night and unfurling them by day, they are a captivating addition to any plant collection. While Calatheas require specific environmental conditions, proper Calathea care can lead to a thriving plant. Additionally, Calatheas are pet-friendly plants, making them a suitable choice for households with animals. Calatheas encompass numerous varieties, each distinguished by unique foliage. Despite their diverse appearances, all Calatheas share common care requirements for optimal growth. At Over Grown, we have a stunning selection of these beautiful plants and our team would love to help you find the perfect one for your space.
Calathea Lighting
Originating from tropical understories, Calatheas thrive in dappled, filtered light, not direct sun exposure.
- Ideal light conditions: Provide bright, indirect light. North-facing windows or positions several feet from east or west-facing windows are often suitable.
- Avoid: Direct sunlight can scorch leaves and diminish pattern vibrancy.
- Signs of improper light: Excessive light can cause faded leaves or crispy edges. Insufficient light may result in leggy growth or reduced coloration.
Calathea Watering
Watering is a critical aspect of Calathea care. They require consistent moisture but can be a little temperamental on the type of water.
- How often to water your Calathea: Water when the top 1-2 inches of soil feel dry. Frequency varies based on environmental factors and pot size, typically every 5-7 days.
- Distilled water for your Calathea: Calatheas are sensitive to chemicals like chlorine and fluoride found in tap water. Using distilled water for Calathea, can prevent brown leaf tips.
Calathea Humidity
These plants are rainforest natives, it is necessary to replicate a high humidity for them to thrive.
- Methods to increase humidity: The best recommendation would be to have a humidifier close-by your calathea collection. Position it to benefit the plant without constantly wetting the leaves. Another method would be to group plants together. Plants release moisture, creating a localized humid climate when grouped.
Calathea Soil and Fertilization
- Potting medium: A well-draining, airy mix that retains some moisture is essential. A standard indoor potting mix is suitable, but we use and recommend Rosy Soil's Houseplant mix for our Calatheas, which can be found in-stores. Check out our blog 'All About Rosy' to learn more about Rosy Soil. It is also recommended to use a pot with proper drainage, to allow water to drain through and not cause rot root to the plant.
- Fertilizing: During the growing season (spring and summer), you can apply a diluted, balanced liquid fertilizer around every 4 weeks. You can reduce fertilization during fall and winter. For a simple way to feed your plant, check out our liquid fertilizer drops. They're available in-store and are perfect for consistent, healthy growth.
Calathea Browning Edges
- Causes: Common factors include low humidity, poor water quality, and inconsistent watering (allowing the soil to dry excessively).
- Solutions: Increase humidity with one of the methods mentioned previously, use distilled water and maintain a consistent watering schedule.
Calathea Curling Leaves
- Causes: Common factors are similar to what is previously mentioned. Causes could include under-watering the plant, low humidity, and/or pests.
- Under-watering: The plant conserves moisture.
- Low humidity: A defense mechanism against dry air.
- Pests: Inspect for infestations that deplete leaf moisture.
- Solutions: Address the underlying issue: water if soil is dry, increase humidity, and treat any detected pests.
Calathea Pests and Treatment
- Common Calathea pests: Monitor for spider mites (indicated by fine webbing, leaf speckling), and mealybugs. (white, cottony bugs)
- Treatment: For infestations, wipe leaves with a damp cloth and apply insecticidal soap. We recommend our organic pest treatment that you can find in either of our store locations to keep infestations at bay and prevent future outbreaks.
