The Philodendron erubescens ‘Black Cherry’, or Black Cherry Philodendron, is a popular houseplant known for its striking deep red to almost black foliage and contrasting red stems. Its glossy, heart-shaped leaves start as deep red and darken with maturity, adding a dynamic visual element. This cultivar is popular due to its unique appearance and relatively straightforward care requirements.
Understanding Black Cherry Philodendron Care
Light Needs
Black Cherry Philodendrons thrive in bright, indirect light, mimicking their natural habitat. A north or east-facing window often provides ideal conditions. Direct sunlight can scorch leaves, causing damage and discoloration. Insufficient light may cause the plant to lose its deep coloration and develop leggy growth, characterized by elongated stems with sparse leaves.
Watering Schedule
Proper watering is crucial for the health of your Black Cherry Philodendron. Allow the top inch or two (2.5-5 cm) of soil to dry out between waterings. Overwatering can lead to yellowing, drooping leaves, and root rot. Conversely, underwatering causes leaves to wilt, become crispy, and develop brown edges.
Soil Requirements
A well-draining, aerated potting mix is essential for Black Cherry Philodendrons to prevent waterlogging and promote healthy root development. An ideal mix includes components like peat moss, perlite, coco coir, or orchid bark. This combination ensures good drainage while retaining moisture and allows for adequate airflow around the roots.
Temperature and Humidity
These tropical plants prefer warm, humid conditions, thriving between 65°F and 80°F (18°C to 27°C). Temperatures below 55°F (13°C) or above 85°F (29°C) can cause stress. High humidity, ideally 60% or higher, benefits their foliage. Increase humidity using a pebble tray, humidifier, or by grouping plants.
Fertilizing
During the growing season (spring through early autumn), fertilize your Black Cherry Philodendron every 4-6 weeks with a balanced liquid fertilizer. Dilute the fertilizer according to product instructions to prevent over-fertilization and root damage. During dormant winter months, reduce or stop fertilizing as the plant’s growth slows.
Maintaining Your Black Cherry Philodendron
Potting and Repotting
Repot your Black Cherry Philodendron every 1-2 years or when it becomes root-bound, indicated by roots growing from drainage holes. Spring is the best time for repotting, aligning with the plant’s active growth. Select a new pot only slightly larger than the current one, ensuring adequate drainage holes.
Pruning for Health and Shape
Pruning maintains the plant’s shape and encourages bushier growth. Remove leggy, yellowing, or damaged leaves to redirect energy towards new development. Use clean, sterilized tools for precise cuts to prevent disease. Regular trimming contributes to overall plant vigor.
Propagating Black Cherry Philodendron
Propagate Black Cherry Philodendron using stem cuttings. Select a healthy stem with at least two nodes, where leaves and roots emerge. Make a clean cut below a node using sharp, sterilized tools. Place the cutting in water, changing it every few days, or in a well-draining potting mix. Once roots develop, typically within a few weeks, transplant the cutting into its own pot.
Common Issues and Troubleshooting
Pest Identification and Control
Black Cherry Philodendrons may encounter common houseplant pests like spider mites, mealybugs, and thrips. Regularly inspect leaves, especially the undersides, to identify infestations early. Treat pests by wiping leaves with a damp cloth or applying insecticidal soap or neem oil.
Addressing Leaf Problems
Leaf issues signal underlying problems. Yellowing leaves often indicate overwatering or nutrient deficiency. Browning tips or edges suggest low humidity or underwatering. Drooping leaves imply too much or too little water. Adjust watering, increase humidity, or provide balanced fertilizer to resolve these issues.
What to Do About Leggy Growth
Leggy growth, characterized by long, sparse stems with widely spaced leaves, is a common sign of insufficient light. This indicates the plant is stretching to find more light. To address this, move your Black Cherry Philodendron to a location that receives brighter, indirect light. Pruning the leggy stems can also encourage bushier, more compact growth.
Safety Considerations
Like other Philodendrons, the Black Cherry Philodendron contains calcium oxalate crystals. Ingesting these crystals can cause irritation, including oral discomfort, swelling, and digestive upset. Keep this plant out of reach of children and pets to prevent accidental ingestion. Individuals with sensitive skin may benefit from wearing gloves when handling the plant.
