Calathea - Plant Drop

Calathea

Calatheas are stunning tropical plants known for their vibrant foliage, making them a popular choice for indoor plant enthusiasts. Here's a comprehensive care guide:

Light

  • Ideal: Bright, indirect light.
  • Avoid: Direct sunlight, which can scorch the leaves and fade their patterns.
  • Adaptability: Tolerates low light but may grow more slowly and lose some vibrancy.

Watering

  • Frequency: Keep the soil consistently moist but not waterlogged.
  • Water Quality: Use distilled, filtered, or rainwater as Calatheas are sensitive to chlorine and fluoride in tap water.
  • Method: Allow the top 2.5 cm (1 inch) of soil to dry out slightly between waterings.

Humidity

  • Requirement: High humidity (50–60% or more).
  • Tips to Maintain Humidity:
    • Use a humidifier.
    • Group plants together.
    • Place on a pebble tray with water (ensure the pot doesn’t sit directly in water).
    • Regular misting, though less effective than the above methods.

Temperature

  • Ideal Range: 18–24°C.
  • Avoid: Cold drafts, sudden temperature changes, and temperatures below 15°C.

Soil

  • Type: Well-draining, rich in organic matter.
  • Mix Suggestions: Use a peat-based mix or combine regular potting soil with perlite or orchid bark for improved drainage.

Fertiliser

  • Frequency: Feed every 4–6 weeks during the growing season (spring and summer).
  • Type: Use a balanced, diluted liquid fertiliser.

Repotting

  • When: Every 1–2 years or when roots outgrow the pot.
  • How: Choose a pot 2–3 cm larger than the current one and ensure it has good drainage.

Pruning

  • Purpose: Remove dead or yellowing leaves to maintain the plant’s appearance.
  • Tools: Use clean, sharp scissors or pruning shears.

Common Problems

  • Leaf Curling or Browning Edges: Often due to low humidity or underwatering. Increase humidity and check watering practices.
  • Yellowing Leaves: May indicate overwatering or poor drainage.
  • Pests: Watch for spider mites, mealybugs, and aphids. Treat with insecticidal soap or neem oil.

Additional Tips

  • Rotate the plant regularly to ensure even growth.
  • Clean the leaves occasionally with a damp cloth to remove dust and improve photosynthesis.

With proper care, your Calathea will thrive and reward you with its vibrant, eye-catching foliage.
