While the Calathea Rufibarba is a relatively easy plant to care for, it does require attention to a few specific conditions to thrive. Here’s everything you need to know about keeping your plant healthy and beautiful:

1. Light Requirements

The Calathea Rufibarba thrives in bright, indirect light. While it can tolerate some low-light conditions, it will show its best colors and patterns when placed in a spot with ample indirect sunlight. Avoid placing it in direct sunlight, as this can scorch the velvety leaves, causing discoloration and damage.

If the plant isn’t getting enough light, you may notice that the leaves become smaller or the vibrant patterns start to fade. A north- or east-facing window with filtered light is the ideal location for this plant. If your space lacks natural light, you can also supplement with a grow light to provide the necessary light for healthy growth.

2. Watering

The Calathea Rufibarba prefers consistently moist, but not soggy soil. Water when the top inch of soil feels dry, and ensure that excess water can drain freely through the pot. Avoid letting the plant sit in standing water, as this can cause root rot.

Use lukewarm water to prevent shocking the roots. Calatheas are also sensitive to fluoride and chlorine in tap water, which can lead to leaf damage. If possible, use distilled water, or let tap water sit out for 24 hours to allow the chemicals to dissipate before watering your plant.

3. Humidity

As a tropical plant, the Calathea Rufibarba thrives in high humidity. The ideal humidity range for this plant is between 60-80%. In homes with dry air, especially during the winter months, you may need to take steps to boost the humidity around your plant.

Here are a few ways to increase humidity:

• Misting: Lightly mist the leaves with water to raise the humidity level.
• Humidifier: Using a humidifier near the plant will help maintain the optimal humidity.
• Humidity Tray: Place the plant on a tray filled with pebbles and water, ensuring the bottom of the pot does not sit directly in the water.
• Grouping Plants: Placing the Calathea Rufibarba alongside other humidity-loving plants can help create a more humid microenvironment.

Be on the lookout for brown leaf tips or curling leaves, as these are common signs of low humidity.

4. Temperature

The Calathea Rufibarba prefers a warm environment with temperatures ranging between 65°F and 75°F (18°C to 24°C). Keep it away from areas with temperature fluctuations, such as near air conditioners, heaters, or drafts. Cold temperatures below 60°F (15°C) can cause stress and stunt growth, so avoid placing it in chilly spots like near open windows during colder months.

5. Soil

For best results, use a well-draining, peat-based potting mix for your Calathea Rufibarba. A mix designed for houseplants works well, but you can improve drainage by adding perlite, orchid bark, or coconut coir. The soil should retain some moisture but not become waterlogged, as too much moisture can cause root rot.

Make sure the pot you use has drainage holes to prevent water from accumulating in the bottom. Never let the plant sit in excess water in the saucer.

6. Fertilizing

During the growing season (spring and summer), feed your Calathea Rufibarba once a month with a balanced, water-soluble fertilizer diluted to half strength. This helps to promote healthy, vibrant growth and maintain the plant’s stunning foliage.

In the fall and winter, reduce fertilizing as the plant’s growth naturally slows down. Over-fertilizing can lead to salt buildup in the soil, which can cause leaf burn and other problems, so it’s better to under-fertilize than overdo it.

7. Pruning

To maintain the plant’s shape and keep it looking fresh, regularly remove any yellowing, dead, or damaged leaves. This not only keeps the plant tidy but also redirects the plant’s energy into producing new growth. You can also prune the Calathea Rufibarba to control its size, especially if it starts to get too large for the space.

8. Repotting

Repot the Calathea Rufibarba every 1 to 2 years or when it outgrows its pot. Choose a pot that is 1-2 inches larger than the current one to allow room for growth. It’s best to repot during the spring or early summer, as the plant will be actively growing at this time and better able to adjust to the new pot.
