Calathea Plant Care: Keep Your Prayer Plant Healthy

Owning a Calathea plant, often referred to as the “prayer plant,” is like having a living piece of art in your home. Known for its vibrant, patterned leaves and the fascinating way its leaves fold up at night, it’s no wonder this plant has become a favourite among plant lovers. But despite its beauty, the Calathea can be a bit fussy when it comes to care. Whether you’re a seasoned plant parent or a beginner, understanding how to keep your Calathea plant healthy and vibrant is essential to enjoying its stunning foliage for years to come.

In this guide, you’ll learn everything you need to know to properly care for your Calathea, from watering and humidity requirements to troubleshooting common issues. With a little effort and attention, you can enjoy the calming presence of a flourishing Calathea in your home.

What is a Calathea Plant?

Before diving into care tips, let’s first explore what makes Calathea so special. Native to the tropical regions of South America, the Calathea belongs to the Marantaceae family, which is also known as the “arrowroot” family. The plant is known for its striking foliage, which features intricate patterns in shades of green, purple, and silver. Some varieties even have vibrant hues of pink or red. The name “prayer plant” comes from the way the leaves fold upwards at night, resembling hands in prayer.

There are several species of Calathea, each with its own unique pattern and colour scheme. Some of the most popular varieties include:

Calathea Ornata (Pinstripe plant): Known for its green leaves with pink or white stripes.
Calathea Lancifolia (Rattlesnake plant): Characterized by long, narrow leaves with wavy edges and dark green spots.
Calathea Zebrina: Features broad, zebra-like stripes on its deep green leaves.

Understanding the different types of Calathea will help you identify your plant and provide it with the best possible care.

Ideal Growing Conditions for Your Calathea Plant

Calatheas are tropical plants, and to thrive, they require conditions similar to their native environment. Creating the perfect home for your plant involves managing factors like light, temperature, humidity, and soil. Let’s break down each of these factors:

Light Requirements: Providing the Right Amount of Sun

One of the most important aspects of Calathea care is light. These plants prefer indirect light that mimics the dappled sunlight found on the forest floor. Direct sunlight can scorch their delicate leaves, causing brown spots or fading colours.

Optimal Light: Bright, indirect light is ideal. A spot near an east- or west-facing window works well.
Avoid Direct Sunlight: Keep your Calathea out of harsh midday sun, as this can cause leaf burn.
Low Light Tolerance: While Calatheas can tolerate lower light conditions, they will grow slower and may not show their full-colour potential.

If you’re struggling to find the right light, a sheer curtain can diffuse sunlight and protect your plant from direct exposure while still offering plenty of brightness.

Temperature: Keep It Warm and Cozy

Calatheas thrive in warm temperatures, similar to those found in their native tropical habitat. Avoid placing your plant near cold drafts or in areas where temperatures fluctuate dramatically.

Ideal Temperature Range: Between 65°F to 80°F (18°C – 27°C). They prefer consistently warm conditions.
Avoid Cold Drafts: Don’t place your Calathea near windows that open frequently or in drafty areas.
Cold Sensitivity: Calatheas are sensitive to temperatures below 50°F (10°C), so make sure your plant is in a cosy spot, especially during winter.

Humidity: Keep It High

Calatheas are humidity-loving plants. If you live in a dry climate or have air conditioning or heating running frequently, you may need to increase the humidity around your plant.

Optimal Humidity: Calatheas do best in 60% to 80% humidity.
Increasing Humidity: Use a humidifier to maintain moisture in the air, or place your plant on a humidifying tray filled with pebbles and water. Misting can help, too, but it’s a temporary solution and should be done sparingly to avoid leaf spots.
Signs of Low Humidity: If you notice the tips of the leaves turning brown or crispy, it’s a sign that your Calathea needs more moisture in the air.

Soil: Well-Draining Yet Moist

The right soil is crucial for your Calathea’s health. They prefer a well-draining mix that retains moisture but doesn’t become soggy. A general-purpose potting mix can work, but adding some perlite or orchid bark will improve drainage and prevent waterlogging.

Best Soil Type: Look for a light, well-draining potting mix with added organic matter. A mix made for houseplants or tropical plants is often ideal.
Repotting: Repot your Calathea every 1-2 years to refresh the soil and prevent it from becoming compacted, which can affect drainage.

Calathea Plant Care Tips: How to Keep Your Prayer Plant Thriving

Now that you know the basics of growing conditions, let’s dive into the day-to-day care your Calathea needs to stay vibrant and healthy.

Watering Your Calathea: How to Find the Right Balance

Watering is one of the most critical aspects of Calathea care. These plants like their soil to be kept moist, but they don’t want to sit in water. Overwatering is a common mistake that can lead to root rot and other issues.

How Often to Water: Water your Calathea when the top 1-2 inches of soil feel dry to the touch. During the warmer months, you may need to water more frequently, about once a week. In cooler months, you can water less often.
Water Type: Use distilled, rainwater, or filtered water. Calatheas are sensitive to fluoride and chlorine found in tap water, which can cause leaf spotting.
Signs of Overwatering: Yellowing leaves and mushy roots are signs of overwatering. Ensure your pot has good drainage to prevent water from pooling at the bottom.

Fertilizing Your Calathea: Encouraging Healthy Growth

Calatheas are relatively light feeders, but regular fertilizing can help them thrive. Use a balanced, water-soluble fertilizer with equal parts nitrogen, phosphorus, and potassium (like a 10-10-10 mix).

Fertilizing Schedule: During the growing season (spring and summer), fertilize once a month. Avoid fertilizing in the fall and winter when the plant is dormant.
Fertilizer Dosage: Always dilute the fertilizer to half strength to avoid over-fertilizing, which can lead to fertilizer burn and damage to the roots.
Signs of Nutrient Deficiency: If your plant’s leaves begin to look pale or the growth slows, it may need additional nutrients.

Pruning and Cleaning Your Calathea: Keep It Neat and Healthy

Pruning and cleaning your Calathea regularly can help maintain its health and appearance. Dead or yellowing leaves should be removed to keep the plant looking fresh.

Pruning: Use clean, sharp scissors to trim away any dead or damaged leaves. This will help the plant focus energy on new growth.
Cleaning: Dust on the leaves can block sunlight and inhibit photosynthesis. Wipe the leaves with a damp cloth to keep them clean and shiny. This also helps improve humidity levels around the plant.

Troubleshooting Common Calathea Problems

Even with the best care, your Calathea might occasionally encounter some issues. Here are a few common problems and how to deal with them:

Yellowing Leaves

Possible Causes: Overwatering, insufficient light, or poor water quality can all cause your Calathea’s leaves to turn yellow.
Solution: Check the watering schedule and make sure you’re not overwatering. Ensure your plant is getting enough indirect light and use filtered water.

Brown Leaf Edges or Crispy Tips

Possible Causes: This is often a sign of low humidity or dry air.
Solution: Increase humidity by using a humidifier or placing a tray of water near the plant. You can also mist the leaves lightly to help with moisture.

Pests and Disease

Common Pests: Spider mites, aphids, and mealybugs are common culprits.
Solution: If you notice small webs or a sticky residue on your plant, it may be infested. Use insecticidal soap or neem oil to treat the problem. Be sure to remove any pests manually first and isolate the affected plant to prevent the spread.

Calathea Propagation: Growing New Plants

If you’d like to grow more Calatheas or share the love with friends, propagation is easy and rewarding. The most common method is dividing the plant.

How to Propagate: In spring, gently remove the plant from its pot and separate the root ball into smaller sections, making sure each division has a few roots attached. Report each section into its container with fresh, well-draining soil.
Care After Propagation: Keep the new plants in a warm, humid environment with indirect light until they establish roots.

Seasonal Calathea Care

Calathea care varies slightly depending on the season. Here’s what you can expect throughout the year:

Summer Care

Calatheas will grow actively in the warmer months so that they will need more water and regular fertilizing.
Be vigilant about humidity, as air conditioning or fans can dry out the environment.

Winter Care

During the cooler months, your Calathea will enter a dormant phase, slowing its growth. Watering should be reduced, but make sure to maintain humidity levels.
Avoid placing your Calathea near heaters or cold windows, as they can damage the plant.
