As September arrives and the days start to shorten, many plants begin to slow down. But some continue to thrive indoors—bringing colour, texture, and movement into our homes. Among them, the Calathea stands out as one of the most decorative and expressive houseplants you can grow.

At Planteka, we help you care for your plants with more confidence and joy. Whether it’s through our workshops, in-depth guides like this one, or personalized Plant Doctor consultations, we’re here to support your green journey every step of the way.

A complete guide to Bougainvillea plant

What is a Calathea?

Native to the tropical rainforests of Central and South America, Calatheas are prized for their spectacular foliage. With bold patterns in shades of green, purple, white, or pink, each variety has its own charm.

Some of the most popular types include:

✔ Calathea orbifolia – large, rounded leaves with silver stripes
✔ Calathea medallion – dramatic circular pattern like a medallion
✔ Calathea lancifolia (rattlesnake plant) – elongated leaves with dark markings
✔ Calathea triostar – pink and cream accents on variegated foliage
✔ Calathea zebrina – velvety leaves with zebra-like striping

And here’s something curious: Calatheas move their leaves throughout the day, closing them at night and opening them in the morning—a natural movement known as nyctinasty.

Basic care tips for Calathea

While Calatheas are known to be a little fussy, with the right conditions they’re rewarding, resilient, and truly eye-catching.

Light

Bright, indirect light is best. Direct sun can scorch the leaves.
Perfect for well-lit rooms with filtered or diffused light.

Watering

Keep the soil lightly moist but never soggy.
Water when the top 2–3 cm of soil feel dry.
Use filtered or rainwater if possible—Calatheas are sensitive to chlorine and hard water.

Humidity

Calatheas love humidity. If your home is dry:
• Use a humidifier
• Group it with other plants
• Set it on a pebble tray with water

Temperature

Keep it in a stable spot between 18–26°C (64–78°F).
Avoid cold drafts and sudden temperature changes.

Soil

Use a well-draining, rich soil mix—tropical plant mix works great.
You can also mix compost with perlite, coco coir, and worm castings.

Can you propagate Calathea?

Yes—but not through cuttings. Calathea is best propagated by division in spring or early summer:

1. Gently remove the plant from its pot
2. Separate a clump with its own roots and leaves
3. Repot in a small container with moist soil
4. Keep warm and humid until it stabilizes

Common issues & what they mean

🔸 Brown tips → Dry air or mineral-rich water
🔸 Curling leaves → Underwatering or low humidity
🔸 Yellow patches → Overwatering
🔸 Droopy foliage → Stress from temperature or watering changes

Why we love Calathea

Because it responds to you. It reacts to light, water, and environment—and teaches you to observe and adjust. In return, it gives you one of the most stunning foliage displays in the plant world.

It’s perfect if you’re looking for a bold, living piece of decor with personality. And September is the ideal time to welcome one into your home.
