How Do I Care For My Calathea Plant?

Calathea plants require specific care to thrive. They prefer indirect light and moderate humidity. Keep the soil consistently moist but not waterlogged, as they are sensitive to both under-watering and over-watering. Regularly misting the leaves can help maintain humidity levels. It’s also crucial to avoid cold drafts and temperatures below 60°F (15°C).

What Are Some Common Varieties Of Calathea?

There are several popular varieties of Calathea, each known for its unique leaf patterns and colors. Some common varieties include Calathea ornata (pink-striped leaves), Calathea lancifolia (rattlesnake plant with elongated leaves), Calathea medallion (round, patterned leaves), and Calathea zebrina (zebra-striped foliage).

How Often Should I Fertilize My Calathea Plant?

During the growing season (spring and summer), fertilize your Calathea plant monthly with a balanced, water-soluble fertilizer diluted to half-strength. Reduce fertilization to every 6-8 weeks during the fall and winter months when growth slows down.

Why Are The Leaves Of My Calathea Plant Turning Brown Or Crispy?

Brown or crispy leaf edges on Calathea plants can indicate several issues, such as low humidity, underwatering, or direct sunlight exposure. Calathea plants prefer high humidity and indirect light. Adjusting these conditions and ensuring the soil remains consistently moist (but not soggy) can help prevent leaf damage.

How Can I Increase Humidity For My Calathea Plant?

Calathea plants thrive in environments with high humidity levels, ideally between 50-60% relative humidity. To increase humidity, you can place a humidifier near the plant, group plants together to create a microclimate, or use a pebble tray filled with water beneath the pot (ensure the pot does not sit in water).

How Do I Propagate My Calathea Plant?

Calathea plants can be propagated through division. Carefully remove the plant from its pot and gently separate the root ball into sections, ensuring each section has healthy roots and stems. Plant each division into its own pot with fresh, well-draining potting mix. Propagation is best done during the spring or early summer when the plant is actively growing.
