Calathea Care Guide

Light Requirements

  • Ideal: Bright, indirect light. Morning sun is fine, but avoid direct, intense light, which can fade colors or scorch leaves.

  • Tolerates: Lower light conditions, but may grow more slowly and lose some vibrancy.

Varieties with bold patterns (like Calathea orbifolia, makoyana, or roseopicta) maintain their striking looks best in moderate filtered light.

Watering

Calatheas are very sensitive to water quality and moisture fluctuations. Keep the soil consistently moist but not soggy.

  • Use filtered, distilled, or rainwater when possible—tap water with fluoride or high mineral content can cause leaf browning.

  • Water when the top ½–1 inch of soil feels dry.

  • Reduce watering slightly in winter.

Signs of water issues:

  • Crispy edges or brown tips = low humidity, poor water quality, or underwatering

  • Yellowing leaves = overwatering or poor drainage

Soil & Potting

  • Use a light, well-draining mix that retains moisture but allows airflow.

    • Ideal blend: peat or coco coir + perlite + orchid bark or worm castings

  • Choose a pot with drainage holes to prevent root rot.

Temperature & Humidity

  • Ideal temp: 65–80°F (18–27°C)

  • Avoid: Temps below 60°F, drafts, and sudden fluctuations

  • Requires high humidity (60%+ preferred)

💡 Boost humidity with:

  • Humidifier (best option)

  • Pebble trays

  • Grouping plants

  • Enclosed cabinet or greenhouse setups

Fertilizer

  • Feed monthly during the growing season (spring–summer) with a balanced, diluted liquid houseplant fertilizer.

  • Avoid overfertilizing—it can lead to salt buildup and root burn.

  • Flush the soil occasionally to prevent nutrient buildup.

Pruning & Maintenance

  • Remove yellowing or damaged leaves with clean scissors.

  • Wipe leaves with a damp cloth to remove dust—don’t use leaf shine products.

Keep your plant in a stable environment with minimal movement or drafts to reduce stress.

Pests & Problems

Calatheas are susceptible to:

  • Spider mites (especially in dry conditions)

  • Fungus gnats (from overly moist soil)

  • Mealybugs or scale on rare occasion

Treat with neem oil, insecticidal soap, or systemic insecticides if necessary. Maintaining high humidity helps deter spider mites.

Toxicity

Non-toxic to pets and humans!
One of the few prayer plant relatives safe for curious cats and dogs.

Propagation

  • Propagation is best done via division during repotting.

  • Gently separate rooted clumps in spring and pot individually.

  • Do not propagate by cuttings—Calatheas don’t root this way.
