The Philodendron ‘Red Moon’ is a popular houseplant. New leaves emerge with vibrant red and orange hues, gradually transitioning to darker, deeper tones as they mature. This distinctive coloration and straightforward care make it a unique visual element for indoor spaces.
Essential Care for Your Philodendron ‘Red Moon’
Light
Philodendron ‘Red Moon’ thrives in bright, indirect light. Placing it near a window with filtered sunlight is ideal. Direct sun exposure can cause leaf burn and scorching. Insufficient light hinders growth and diminishes the intensity of its vibrant red and orange colors.
Watering
The “soak and dry” method is recommended for watering. Allow the top 1-2 inches (3 cm) of soil to dry out before watering again. Keep the soil moist but never soggy, as overwatering can lead to root rot. Underwatering can cause leaves to wilt or develop brown tips. Watering frequency depends on pot size, humidity, and season, with less water needed in winter.
Soil Requirements
The Philodendron ‘Red Moon’ prefers a well-draining, aerated soil mix rich in organic matter. A chunky tropical houseplant mix provides good air circulation around the roots. Incorporating perlite and orchid bark improves drainage, while coco coir aids moisture retention without waterlogging. Avoid dense or sandy soil mixes to prevent root suffocation.
Temperature and Humidity
Philodendron ‘Red Moon’ grows best in warm temperatures, ideally 65°F to 80°F (18°C to 27°C). It tolerates temperatures as low as 55°F, but consistent warmth promotes better growth. As a tropical plant, it appreciates high humidity, ideally above 60%. To increase humidity, use a humidifier, place the plant on a pebble tray, or group it with other plants.
Fertilizing
Fertilize Philodendron ‘Red Moon’ during its active growing season, typically spring and summer. Apply a balanced liquid fertilizer, diluted to half strength, monthly. Avoid over-fertilizing, as it can lead to nutrient burn, causing leaves to droop or curl. During the plant’s dormant winter season, fertilization is generally not necessary, as growth slows significantly.
Understanding the ‘Red Moon’ Variegation
The ‘Red Moon’ is known for its unique coloration. New leaves unfurl with vivid shades of red, orange, and yellow, most prominent on freshly emerged foliage. As leaves mature, these vibrant hues gradually deepen or transition to darker tones of green, burgundy, or pale lime. This color shift is a natural part of the plant’s development.
Optimal bright indirect light significantly enhances the intensity and vibrancy of the red and orange pigments. While good light encourages stronger colors, some fading or deepening to green is expected as leaves age. The variegation is genetically determined, distinguishing it from other philodendron varieties.
Propagating Philodendron ‘Red Moon’
Propagate Philodendron ‘Red Moon’ using stem cuttings. Select a healthy stem section, 3 to 6 inches long, with at least one or two nodes. Nodes are points where leaves and aerial roots emerge, and new growth develops. Make a clean cut below a node, ensuring no leaves are submerged if rooting in water. Remove lower leaves to prevent rotting.
Cuttings can root in water or a moist substrate like sphagnum moss or an airy potting mix. Change water regularly if rooting in water. Placing cuttings in a warm location with bright, indirect light promotes root development. Roots typically form within a few weeks. Once roots are a few inches long, transplant the cutting into a suitable potting mix.
Troubleshooting Common Issues
Common issues with Philodendron ‘Red Moon’ can often be resolved with care adjustments.
If the vibrant red or orange coloration on new leaves appears dull or fades quickly, it often indicates insufficient light. Moving the plant to a brighter spot with indirect sunlight can help enhance the color intensity.
Yellowing leaves frequently signal improper watering, with overwatering being a common culprit leading to root rot. Allow the soil to dry more between waterings and ensure proper drainage. Yellowing can also stem from underwatering or nutrient deficiencies; assess soil moisture and consider a balanced fertilizer.
Brown tips or edges on leaves usually point to low humidity or inconsistent watering. Increase ambient humidity through humidifiers or pebble trays, and maintain a consistent watering schedule.
Leggy growth, characterized by stretched stems with sparse leaves, indicates insufficient light. Relocate the plant to a brighter area and prune back leggy sections to encourage bushier growth.
Pest infestations, such as spider mites, mealybugs, or aphids, can also affect ‘Red Moon’ philodendrons. Regularly inspect the plant for signs of pests and treat them promptly with organic solutions like neem oil or insecticidal soap to protect plant health.
