Calathea Sanderiana or Calathea Ornata Pink

Calathea Sanderiana, commonly known as Calathea Ornata ‘Pink’ or simply Pinstripe Calathea, is a striking tropical houseplant admired for its large, dark green leaves adorned with elegant pink and white stripes. The undersides of the leaves are typically a deep purple, adding to its visual appeal. Native to South America, this member of the Marantaceae family is known for its intricate leaf patterns and vibrant colors, making it a popular choice among plant enthusiasts. However, Calathea Sanderiana requires specific care to thrive due to its sensitivity to environmental conditions. Here’s a comprehensive guide to caring for Calathea Sanderiana:

1. Light Requirements

• Bright, Indirect Light: Calathea Sanderiana thrives in bright, indirect light. It should be placed near a window with filtered sunlight or in a well-lit room where it can receive plenty of indirect light. Too much direct sunlight can scorch the leaves, causing them to lose their color and develop brown edges.
• Tolerates Low Light: While it prefers bright, indirect light, Calathea Sanderiana can tolerate lower light conditions. However, in low-light environments, its growth may slow, and the vibrant colors of its leaves may be less pronounced.

2. Watering

• Consistent Moisture: Keep the soil consistently moist but not waterlogged. Water the plant when the top inch of soil feels dry to the touch. Use lukewarm, distilled, or filtered water, as Calatheas are sensitive to the chemicals and salts often found in tap water.
• Humidity: High humidity is essential for Calathea Sanderiana. Aim for humidity levels between 60-80%. Mist the leaves regularly, place a humidity tray nearby, or use a humidifier to maintain adequate moisture levels in the air. This is especially important in dry climates or during the winter months when indoor air can be dry.

3. Soil

• Well-Draining, Peat-Based Soil: Use a well-draining potting mix that retains moisture but allows excess water to drain away. A mix of peat moss, perlite, and regular potting soil works well. Peat helps retain moisture, while perlite improves drainage and aeration.
• Slightly Acidic to Neutral pH: Calathea Sanderiana prefers a soil pH range of 6.0 to 6.5.

4. Temperature and Humidity

• Warm Temperatures: This plant thrives in warm temperatures between 65-80°F (18-27°C). It should be kept away from cold drafts, air conditioning vents, and temperatures below 60°F (15°C).
• High Humidity: Calathea Sanderiana requires high humidity to prevent the edges of the leaves from browning or curling. To increase humidity, mist the leaves daily, place the plant on a humidity tray, or use a humidifier.

5. Fertilizing

• Regular Feeding: Feed the plant every 4-6 weeks during the growing season (spring and summer) with a balanced, water-soluble fertilizer diluted to half strength. This helps promote healthy growth and vibrant leaf coloration.
• Reduce Feeding in Winter: Fertilizing is not necessary in the winter when the plant’s growth slows down.

6. Pruning and Maintenance

• Remove Yellow or Damaged Leaves: Regularly trim off any yellowing, browning, or damaged leaves to maintain the plant’s appearance and encourage healthy new growth. Use clean, sharp scissors or pruning shears.
• Cleaning Leaves: Wipe the leaves with a damp cloth periodically to remove dust and keep them looking vibrant. This also helps the plant absorb more light.

7. Propagation

• Division: The most common method of propagating Calathea Sanderiana is by division. During repotting, carefully separate the plant into smaller sections, ensuring each section has a portion of the root system and healthy leaves. Plant the divisions in separate pots with fresh potting mix.
• Stem Cuttings: Unlike some other plants, propagation through stem cuttings is not typically recommended for Calathea Sanderiana, as it does not root well from cuttings.

8. Pests and Diseases

• Common Pests: Calathea Sanderiana can be susceptible to pests such as spider mites, aphids, and mealybugs. Regularly inspect the plant and treat infestations with insecticidal soap, neem oil, or a mixture of water and mild dish soap.
• Fungal Issues: Overwatering can lead to root rot and other fungal problems. Ensure good air circulation around the plant and avoid waterlogging the soil to prevent these issues.

9. Indoor Growing

• Great for Low Light Areas: Calathea Sanderiana is well-suited for indoor environments due to its tolerance of low light and relatively low maintenance needs. It’s a great choice for offices, living rooms, and bedrooms.
• Air-Purifying Qualities: Like other Calathea varieties, it is known for its air-purifying qualities, helping to remove toxins like formaldehyde and benzene from the air.

10. Toxicity

• Non-Toxic: Calathea Sanderiana is non-toxic to pets and humans, making it a safe choice for households with cats, dogs, or children.

11. Container Growing

• Pot Requirements: Choose a pot with drainage holes to prevent waterlogging. Use a high-quality, well-draining potting mix and repot every 1-2 years or when the plant becomes root-bound. Repotting provides fresh nutrients and space for new growth.
• Decorative Containers: Calathea Sanderiana looks stunning in decorative containers that complement its elegant, striped foliage. Ensure the container size accommodates the plant’s growth.

12. Overwintering

• Indoor Protection: If grown outdoors in summer, bring the plant indoors before the first frost. Place it in a bright location with indirect light and maintain humidity levels to keep the plant healthy during winter.

By following these care tips, your Calathea Sanderiana will thrive, showcasing its beautiful pinstripe-patterned foliage and adding a touch of elegance to your indoor space. This plant’s sensitivity to environmental changes makes it a rewarding choice for plant enthusiasts who enjoy providing the specific care required to keep it healthy and vibrant.
