The Philodendron ‘Emperor Green’ is a popular houseplant, known for its robust nature and vibrant appearance. Its straightforward care makes it suitable for both new and experienced plant enthusiasts. The striking foliage and upright growth enhance indoor spaces.
Understanding Emperor Green Philodendron
Distinctive Features
The Philodendron ‘Emperor Green’ is distinguished by broad, oval, and slightly elongated leaves. These large leaves, up to 18 inches long, boast a deep, glossy emerald green hue and fan out from short stems. Rigid petioles sometimes feature a pink-tinged sheath, adding a decorative contrast. This combination of large, shiny leaves and a compact form makes it visually appealing.
Growth Habits
Unlike vining philodendrons, the ‘Emperor Green’ is a self-heading type, growing upright in a compact, bushy form without external support. Indoors, it typically reaches 2 to 3 feet in height and spread. It exhibits a moderate to fast growth rate under optimal conditions, developing significantly within a year. Its self-supporting structure and dense foliage make it an ideal potted plant for various indoor settings.
Comprehensive Care Guide
Light Requirements
The Philodendron ‘Emperor Green’ thrives in bright, indirect light, mimicking its natural habitat. An east or north-facing window is ideal, providing gentle morning or diffused ambient light. While it tolerates lower light, sufficient indirect light maintains vibrant foliage and growth. Avoid direct, intense afternoon sun, which can scorch leaves, causing yellowing, browning, or burnt patches.
Watering Practices
Proper watering is essential, as the ‘Emperor Green’ Philodendron prefers consistently moist but not waterlogged soil. Check soil dryness by allowing the top 1 to 2 inches to dry out before watering. Overwatering can lead to root rot, so good drainage is paramount. Water thoroughly until excess drains from the pot’s holes, then ensure the plant does not sit in standing water. Watering frequency adjusts seasonally, with more needed during spring and summer, and less in fall and winter.
Soil Mix and Potting
The ‘Emperor Green’ Philodendron flourishes in a well-draining, aerated soil mix. A suitable blend includes equal parts potting mix, perlite, and pine or orchid bark to enhance drainage. Sphagnum peat moss or coconut coir helps retain moisture while allowing excess water to drain. Ensure the pot has drainage holes to prevent root rot. Refreshing the soil mix every one to two years maintains optimal plant health and nutrient availability.
Temperature and Humidity
This philodendron thrives in warm, humid conditions, reflecting its tropical origins. Ideal temperatures range from 65°F to 85°F (18°C to 29°C) during the day, with slightly cooler nights. Protect the plant from sudden temperature drops and cold drafts to prevent stress. While it tolerates average household humidity, it prefers 50% to 60%. To increase humidity in drier environments, mist regularly, use a humidifier, or place the pot on a pebble tray.
Fertilization Schedule
The ‘Emperor Green’ Philodendron benefits from regular fertilization during its active growing season to support lush foliage. A balanced liquid fertilizer (e.g., 10-10-10 or 20-20-20), applied at half-strength, is suitable. During spring and summer, fertilize every 4 to 6 weeks. Reduce or stop fertilization in fall and winter when growth slows. Avoid over-fertilization, which can lead to root burn and yellowing leaves.
Repotting and Maintenance
When to Repot
Repotting is necessary when the ‘Emperor Green’ Philodendron outgrows its container, indicated by roots emerging from drainage holes or circling the pot. Stunted growth can also signal the plant is root-bound. The best time to repot is during the active growing season, primarily spring or early summer, allowing time to establish in the new pot. Repot every one to two years until the plant reaches mature size.
How to Repot
When repotting, select a new pot 1 to 2 inches larger in diameter to avoid overwatering. Gently remove the plant, loosening circling roots and shaking off old soil. Inspect roots for rot (mushy or black sections) and trim if needed. Place fresh, well-draining potting mix at the bottom, position the plant, and fill around the root ball, maintaining the same depth. Water thoroughly after repotting to settle the soil.
Pruning and Cleaning
Pruning the ‘Emperor Green’ Philodendron maintains its shape, encourages denser foliage, and removes damaged or yellowing leaves. Use clean, sharp shears to cut dead, discolored, or leggy stems at their base or above a leaf node. Spring and early summer are best for substantial pruning, allowing efficient recovery and new growth. Avoid heavy pruning in fall and winter to prevent stressing the plant. Regularly clean glossy leaves with a damp cloth to remove dust, aiding light absorption and discouraging pests.
Propagation Techniques
Stem Cuttings
Propagating the ‘Emperor Green’ Philodendron using stem cuttings is a common method. Select a healthy stem with at least two to three nodes, approximately 4 to 6 inches long. Nodes are where leaves attach and new roots form. Using sterilized shears, make a clean cut just below a node. Remove lower leaves near the cut end to expose nodes for rooting in water or soil.
Water Propagation
For water propagation, place the prepared stem cutting into a glass jar with purified or room-temperature water, ensuring at least one node is submerged. Change the water every few days to prevent bacterial growth. Position the jar in bright, indirect sunlight. Roots typically emerge from nodes within two to four weeks. Once roots are a few inches long, transition the cutting into potting mix.
Soil Propagation
To propagate directly in soil, fill a small pot with a sterile, well-draining potting mix (e.g., peat moss and perlite) and moisten it lightly. Create a small hole and insert the cutting, ensuring at least one node is buried. Gently pat soil around the cutting. Place the potted cutting in a warm location with bright, indirect light, maintaining consistent soil moisture. Covering the pot with a plastic bag creates humidity; ensure airflow to prevent mold.
Troubleshooting Common Issues
Leaf Discoloration
Leaf discoloration in ‘Emperor Green’ Philodendron often signals a care issue. Yellowing leaves, especially lower ones, commonly indicate overwatering or poor soil drainage, which can lead to root rot. Reduce watering and ensure well-draining soil with adequate drainage holes. Brown, crispy leaf tips or edges suggest insufficient humidity or underwatering; increase humidity with misting or a pebble tray. Brown patches or faded color usually result from too much direct sunlight; move the plant to bright, indirect light to prevent further damage.
Pest Infestations
While generally pest-resistant, the ‘Emperor Green’ Philodendron can be susceptible to common houseplant pests like spider mites, mealybugs, and scale insects. Signs include irregular yellow spots, holes, or visible pests. Regularly inspect the plant, especially leaf undersides and stem joints, for early detection. For treatment, spray with a water and dish soap solution, or use commercial insecticidal soaps for persistent infestations.
Leggy Growth
Leggy growth, characterized by stretched stems and sparse foliage, indicates insufficient light. The plant stretches towards a light source, resulting in an elongated appearance. To rectify this, move the plant to a brighter location with ample bright, indirect light. Pruning leggy stems encourages bushier, more compact growth by stimulating new shoots. Regularly rotating the plant ensures even light exposure, promoting balanced growth.
Slow Growth or Stunted Development
Slow growth or stunted development in an ‘Emperor Green’ Philodendron can stem from insufficient light, nutrient deficiency, or being root-bound. Inadequate bright, indirect light slows metabolic processes. A lack of essential nutrients inhibits development; a consistent fertilization schedule during the growing season can help. If the plant is root-bound, repotting into a slightly larger container with fresh soil provides space and resources for renewed growth.
