The Calathea Red Mojo, also known as the Red Mojo Prayer Plant, is a striking ornamental houseplant. It features large, oval-shaped leaves with vibrant deep green tops and contrasting deep red or burgundy undersides. This plant is admired for its unique “prayer plant” movement, where its leaves fold upwards at night and unfurl in the morning. Native to the tropical rainforests of South America, it thrives in warm, humid conditions and filtered light, making it a popular indoor choice.
Caring for Calathea Red Mojo
Light Requirements
Calathea Red Mojo thrives in bright, indirect light, similar to its natural rainforest habitat. Direct sunlight can scorch the delicate leaves and cause their vibrant colors to fade. An ideal placement is near a window with a sheer curtain or in a well-lit room away from south or west-facing windows. Insufficient light may cause the leaves to appear washed out.
Watering Needs
Maintaining consistent soil moisture is important for Calathea Red Mojo, but avoid waterlogging. Water when the top inch (2-3 cm) of soil feels dry, typically every 5-7 days. Overwatering can lead to root rot, while allowing the soil to dry out completely causes leaves to brown and crisp. Using filtered, distilled, or rainwater is recommended to prevent mineral buildup and issues like leaf yellowing or browning, as these plants are sensitive to chemicals in tap water.
Humidity Preferences
High humidity, ideally between 60% and 80%, is crucial for Calathea Red Mojo, replicating its native tropical environment. Low humidity can lead to browning or crisping leaf edges. To increase humidity, place the plant on a pebble tray filled with water (ensuring the pot is not submerged) or use a nearby humidifier.
Soil and Potting
A well-draining yet moisture-retentive potting mix is best for Calathea Red Mojo, often including peat moss and perlite. The pot should always have drainage holes to ensure excess water can escape, preventing root issues.
Temperature Range
Calathea Red Mojo thrives in warm conditions, with an ideal temperature range of 18-24°C (65-85°F). It is sensitive to cold and sudden temperature fluctuations. Avoid placing the plant near cold drafts from windows or air conditioning units, as this can cause stress and leaf damage.
Fertilizing Your Plant
During the active growing season (spring and summer), fertilize your Calathea Red Mojo every two to four weeks. Use a balanced liquid fertilizer, diluted to half strength, to promote new growth and maintain vibrant foliage. Reduce or stop fertilizing during the fall and winter months when the plant’s growth slows.
Addressing Common Problems
Leaf Browning or Crisping
Browning or crisping leaf edges often indicates insufficient humidity, inconsistent watering, or sensitivity to tap water minerals. To address this, increase ambient humidity using a humidifier or pebble tray. Ensure the soil remains consistently moist, not soggy, and consider switching to filtered or distilled water for irrigation.
Fading Leaf Color
If the vibrant patterns and colors of your Calathea Red Mojo’s leaves begin to fade, it usually suggests too much direct light exposure. Direct sunlight can bleach the foliage. Relocate the plant to a spot with bright, indirect light to restore its rich coloration.
Pest Infestations
Calathea Red Mojo can attract common houseplant pests like spider mites and mealybugs, especially in dry environments. Regularly inspect the undersides of leaves for any signs. For treatment, wipe leaves with a damp cloth or apply insecticidal soap or neem oil. Increasing humidity can also help deter spider mites.
Propagating Calathea Red Mojo
Propagate Calathea Red Mojo through division, often performed when repotting. This involves carefully separating the plant into smaller sections, each with its own roots and foliage. Gently remove the plant from its pot and tease apart the root ball into clumps. Ensure each new division has a healthy section of rhizome and a few leaves. Pot these plantlets into their own containers with well-draining soil.
