The Imperial Green Philodendron (Philodendron erubescens ‘Imperial Green’) is a popular and attractive houseplant, bringing lush green foliage into any indoor space. Appreciated for its striking appearance and relatively straightforward care, it suits a wide range of plant enthusiasts.
What is the Imperial Green Philodendron?
The Imperial Green Philodendron is a hybrid plant, cultivated for its distinctive characteristics. It features large, glossy, deep green leaves that are typically broad and oval-shaped. Unlike many climbing philodendron varieties, it grows upright in a bushy, self-heading pattern, requiring no external support. This compact growth makes it an excellent choice for tabletops or floor displays.
Imperial Green Philodendron Care Guide
Light Requirements
Imperial Green Philodendrons thrive in bright, indirect light. Placing them near an east-facing window for gentle morning sun is ideal. While they tolerate lower light, growth may slow. Too much direct sunlight can scorch leaves, leading to browning. Insufficient light causes leggy growth, while excessive light manifests as yellowing or crispy brown leaf edges.
Watering Needs
Water the plant when the top two inches of soil feel dry. Overwatering leads to root rot, so good drainage is essential to prevent waterlogging. Watering frequency depends on environmental factors, but mature plants can tolerate occasional drought.
Soil and Potting
A well-draining potting mix rich in organic matter provides an optimal growing environment. A blend incorporating peat moss, perlite, or coarse sand ensures proper aeration and drainage. The ideal soil pH ranges from slightly acidic to neutral (5.5-6.5). Always use pots with drainage holes to allow excess water to escape, protecting the plant from root problems.
Temperature and Humidity
Imperial Green Philodendrons prefer warm indoor temperatures, ideally between 65°F and 85°F (18°C-29°C). They are sensitive to cold drafts and sudden temperature fluctuations. As tropical plants, they appreciate higher humidity. To increase humidity, consider using a pebble tray, grouping plants, or employing a room humidifier.
Fertilizing
During the active growing season (spring through fall), Imperial Green Philodendrons benefit from regular fertilization. Apply a balanced liquid fertilizer, diluted to half strength, every two to four weeks. Over-fertilization can cause root burn and leaf yellowing, so follow dilution guidelines. Plants in lower light conditions generally require less frequent fertilization.
Repotting and Propagating
Repotting Your Plant
Repotting is necessary when the plant becomes root-bound, indicated by roots growing out of drainage holes or circling the pot. The best time is during the growth period, from late spring through mid-summer. Choose a new pot one to two inches larger in diameter to prevent excess soil moisture. Gently remove the plant, loosen any circling roots, and replant with fresh, well-draining soil mix.
Propagating New Plants
Propagate Imperial Green Philodendrons through stem cuttings. Select a healthy stem with at least two to three nodes (the bumps where leaves emerge) and cut it just below a node. Remove any lower leaves that would be submerged. Place the cutting in water, changing it regularly, or directly into a moist, well-draining potting mix. Keep the cutting in a warm, bright location away from direct sunlight until new roots and growth appear.
Common Problems and Solutions
Yellowing leaves often indicate overwatering or nutrient deficiency; adjust watering to allow topsoil to dry. Brown tips or edges suggest low humidity or underwatering; increase humidity or ensure consistent moisture. Drooping leaves can signal both underwatering and overwatering; check soil moisture to determine the cause.
Pests like spider mites, mealybugs, and scale may infest the plant. Inspect leaves regularly, especially undersides, and treat infestations with horticultural oil or insecticidal soap. Removing dust from leaves with a damp cloth also helps prevent pests and improves plant health.
Is Imperial Green Philodendron Toxic?
Yes, the Imperial Green Philodendron is toxic to humans and pets if ingested. It contains calcium oxalate crystals, which can cause irritation to the mouth, throat, and digestive tract. Keep the plant out of reach of children and household pets to prevent accidental ingestion.
