Calathea Plant Care Guide:
Tips and Tricks for Healthy Growth

Updated: April 9, 2023

Calathea plants are known for their beautiful foliage and unique patterns. They are popular houseplants because they are easy to care for and add a touch of tropical elegance to any space. However, like most plants, they require proper care and attention for healthy growth and longevity.

In this article, we will provide you with the essential tips and tricks for Calathea plant care to help you keep your plant healthy and thriving.

Light Requirements

Calathea plants prefer indirect light or partial shade. Direct sunlight can damage their leaves, causing them to turn brown or yellow. If you have a south-facing window that receives direct sunlight, it’s best to place your Calathea plant a few feet away from the window or use a sheer curtain to filter the light.

If your Calathea plant is not getting enough light, its leaves may start to curl or droop. In such cases, it’s best to move the plant to a brighter location.

Watering

Calathea plants like moist soil but can be sensitive to overwatering. It’s essential to keep the soil evenly moist but not waterlogged. You can check if your plant needs watering by sticking your finger into the soil about an inch deep. If it feels dry, it’s time to water your plant.

It’s also important to avoid using hard water or tap water with high levels of fluoride or chlorine. These chemicals can damage the plant’s roots and cause leaf discoloration. Instead, use distilled or filtered water or let tap water sit out overnight before watering.

Humidity

Calathea plants thrive in humid environments. If the air in your home is dry, you can increase humidity by misting your plant regularly with a spray bottle or placing a humidifier nearby.

You can also create a DIY humidity tray by filling a shallow tray with pebbles and water. Place your Calathea plant on top of the pebbles, ensuring that its roots do not touch the water. As the water evaporates, it will increase humidity around the plant.

Fertilizer

Calathea plants benefit from regular fertilization during their growing season (spring and summer). Use a balanced houseplant fertilizer every two weeks to provide essential nutrients for healthy growth.

It’s important not to over-fertilize your Calathea plant as this can cause fertilizer burn, which damages the roots and leaves. Always follow the instructions on the fertilizer package and dilute it according to the recommended ratio.

Temperature

Calathea plants prefer warm temperatures between 65-80°F (18-27°C). They are sensitive to cold drafts and sudden temperature changes, which can cause leaf damage and stunted growth.

It’s best to keep your Calathea plant away from windows, doors, and air conditioning units that can cause temperature fluctuations.

Repotting

Calathea plants need to be repotted every two years or when their roots become pot-bound. When repotting, choose a pot that is one size larger than the current one and use well-draining soil mix.

It’s essential not to damage the roots during repotting as this can cause transplant shock. Gently loosen any tangled roots and remove any dead or rotten ones before planting in new soil.

FAQ

Q: Why are my Calathea leaves turning brown?

A: Brown leaves on Calathea plants could be due to various reasons such as overwatering, underwatering, exposure to direct sunlight, low humidity, or pests. Check if you are providing optimal lighting conditions, watering correctly, maintaining humidity levels, and inspecting for pests.

Q: Can I propagate my Calathea plant?

A: Yes, Calathea plants can be propagated through division. Divide the plant during repotting by gently separating the rhizomes and planting them in separate pots with fresh soil mix.

Q: How often should I fertilize my Calathea plant?

A: Fertilize your Calathea plant every two weeks during its growing season (spring and summer) with a balanced houseplant fertilizer diluted according to instructions on the package.

In conclusion, following these tips and tricks will help you maintain healthy growth in your Calathea plant. With proper care and attention, your Calathea can thrive for many years as an elegant addition to your indoor garden.
