Why Calathea Are a Houseplant Favourite

Calatheas stand out thanks to their striking patterned leaves, variety of colourations, and the unique “prayer plant” movement - many species fold their leaves at night and open them again by day, adding a subtle living rhythm to your home.

As rainforest understory natives, they thrive in indirect light, warmth and humidity - perfect if you want tropical vibes without needing a conservatory. Their size range makes them suitable for desktops, shelves, windowsills or feature plant spots.

With proper care, Calatheas bring colour, texture, and a lush interior aesthetic - offering both statement greenery and calming houseplant energy.

How to Care for Your Calathea

Light:

Calatheas thrive in bright but indirect light. Avoid harsh direct sunlight which can scorch their leaves; filtered light or a spot near a north- or east-facing window works well.

Humidity & Temperature:

These tropical plants enjoy stable warmth and high humidity. Aim for consistent indoor temperatures and consider misting or placing them on a humidity tray, especially during dry seasons.

Watering:

Keep the soil evenly moist, but never waterlog. Water when the top 2 inches of the soil begins to dry - don’t let the compost dry out completely.

Soil & Potting:

Use a well-draining, airy potting mix. Avoid heavy, water-retentive soils that can lead to root problems.

Feeding:

During the growing season, feed occasionally with a balanced houseplant fertiliser to support healthy leaf growth and vibrant foliage.

Maintenance:

Wipe leaves occasionally to remove dust, prune any yellowing leaves, and avoid placing near drafts or heating vents which could dry out soil or air too quickly.

Frequently Asked Questions - Calathea & Prayer Plants

What is a Calathea (or Prayer Plant)?

Calathea is a genus of tropical houseplants known for their broad, patterned leaves and decorative appeal. Because many fold their leaves at night and open them in the day, they’re often called “prayer plants.”

Where should I place my Calathea at home?

Choose a bright spot with indirect light - near a window but out of direct sunlight. Bathrooms or kitchens with humidity, or rooms with indirect filtered light, are ideal.

How often should I water it?

Water when the top part of soil begins to dry, but never allow the compost to dry out completely. Keep soil lightly moist (not soggy) for best results.

Does Calathea need high humidity or special conditions?

Yes - these plants appreciate humidity and stable warmth. Regular misting, a pebble tray, or grouping with other plants helps replicate their tropical conditions.

Why are my Calathea’s leaf edges turning brown or curling?

Common causes: too much direct sunlight, low humidity, tap water with chemicals, or fluctuations in temperature. Try filtered water, increase humidity, and reposition away from direct sun or heaters.

Are Calatheas safe for pets?

Most varieties are non-toxic to pets, making them a good option for homes with animals - but as with any plant, avoid letting pets chew leaves, and check the specific variety’s safety if in doubt.

How big do Calatheas get indoors?

Depending on the variety, many stay compact (ideal for desks, shelves, or small spaces); others can grow larger under good conditions. Growth is generally moderate - patience pays off.
