Care Calathea

This tropical houseplant is not difficult to care for, but it’s important to be aware of the right care tips so you can enjoy your Calathea for many years. The Calathea is known not only for its striking patterns, but also for its “living” behaviour — its leaves move throughout the day. With the right care, your Calathea will stay healthy, vibrant and a true centrepiece in your home.

Best placement for the Calathea

The prayer plant prefers indirect light and grows best in a spot with bright, filtered daylight. Too much direct sunlight can burn the leaves and cause brown spots. A position near a north- or east-facing window is ideal, providing plenty of light without harsh sun exposure.

A spot with partial shade also suits the Calathea well. Avoid draughts or cold air flowing from windows or doors. The plant appreciates a stable environment without frequent relocation.

Watering your Calathea

Calatheas prefer consistently moist soil. It’s important to keep the soil lightly moist, but never waterlogged. Water the plant 1–2 times per week, depending on the temperature and humidity in your home.

Allow the top layer of soil to dry slightly between waterings.

Good drainage is essential to prevent root rot. Use rainwater or distilled water where possible, as Calatheas are sensitive to minerals in tap water.

Humidity and temperature

Calatheas originate from tropical rainforests, so they love high humidity. Aim for at least 50% humidity, especially during winter when indoor air can become dry due to heating. Increase humidity by regularly misting the leaves with a plant sprayer or using a humidifier.

The ideal temperature is between 18°C and 24°C. Avoid sudden temperature changes and do not place the plant near cold draughts or heating units.

Pot and soil for the Calathea

Use a lightweight, well-draining potting mix that retains some moisture, ensuring the roots stay healthy without becoming waterlogged. A mixture of indoor plant soil with some vulcastrat works perfectly.

A pot with drainage holes is essential to prevent standing water at the bottom.

Fertilising the Calathea

The Calathea has modest nutritional needs. During the growing season (March to September), feed the plant monthly with diluted liquid houseplant nutrition.

Always dilute the fertiliser well to avoid overfertilising. Outside the growing season, the plant does not need extra feeding — during this rest period, it absorbs fewer nutrients. Excess fertiliser can acidify the soil and harm the roots.

Repotting the Calathea: how and when?

Repot your Calathea every 1–2 years to provide the roots with enough space. Choose a new pot that is 2–3 cm larger than the previous one. Repot preferably in spring, when the plant begins its active growth period and recovers quickly.

Use fresh soil and remove any old or damaged roots. Regular repotting keeps the plant healthy, stimulates growth, and prevents root congestion.

Pruning the Calathea

Pruning is not always necessary, but it can help maintain the plant’s shape or make it grow more compact. Remove unattractive or damaged leaves with clean scissors and trim overly long stems to encourage new branching.

The best time to prune is in spring or early summer, when the plant is actively growing.

Propagating the prayer plant

The Calathea is best propagated by dividing the root ball during repotting. Ensure each division has enough roots and remains well hydrated until it has established itself.

Common problems with Calathea

• Yellow leaves: too much water, too much direct light, or nutrient deficiency
• Brown leaf tips: dry air or irregular watering
• Leaf loss: adjusting to a new environment or sudden temperature changes
• White residue: lime or dust — wipe leaves clean with a damp cloth
• Pests: such as spider mites or aphids — inspect regularly and treat early with a biological product
