The Philodendron Narrow Leaf is a popular houseplant known for its distinctive elongated foliage. Its unique leaf shape, with deep serrations along the edges, brings a touch of the tropics indoors. Its striking appearance and straightforward care make it a popular choice for plant lovers.
Understanding Philodendron Narrow Leaf
The plant, botanically known as Philodendron ‘Narrow’, is a cultivated hybrid. It is also sold under common names like ‘Tiger Tooth Philodendron’ or ‘Jungle Boogie’. Unlike some climbing Philodendrons, this variety typically grows upright and shrub-like, though it can benefit from support as it matures.
Its defining feature is its long, lanceolate leaves with deeply serrated or jagged edges. These glossy, deep green leaves create a dramatic appearance, resembling a tiger’s tooth. The ‘Narrow’ cultivar is recognized for its distinct, finely serrated and elongated leaf form. Many Philodendrons, including this type, originate from the tropical regions of South and Central America, thriving in warmth and humidity.
Comprehensive Care Guide
Light Requirements
Philodendron Narrow Leaf thrives in bright, indirect light, similar to its natural habitat. Place the plant near an east or north-facing window, or a few feet from a south or west-facing window. Insufficient light leads to stunted growth and smaller leaves, while direct sunlight can cause dull, washed-out foliage or brown patches.
Watering Practices
Proper watering is key for Philodendron Narrow Leaf, which prefers consistently moist soil. Allow the top two inches of soil to dry out between waterings. Overwatering often causes yellowing leaves, while underwatering results in brown, crispy leaf edges. Ensure the pot has drainage holes to prevent waterlogging and root rot.
Soil Mix
An ideal soil mix for Philodendron Narrow Leaf offers excellent drainage, good aeration, and retains some moisture. A suitable blend includes peat moss or coco coir for moisture retention, perlite or pumice for drainage, and orchid bark or coarse sand for aeration. This prevents compaction, allowing roots to breathe.
Temperature and Humidity
These tropical plants prefer warm environments, ideally between 18 to 25 degrees Celsius (65-77 degrees Fahrenheit). They require high humidity, around 60-80%, to prevent leaf browning and support healthy growth. To increase humidity, use a pebble tray, a room humidifier, or group plants together.
Fertilizing
During spring and summer, Philodendron Narrow Leaf benefits from regular fertilization. Apply a balanced liquid fertilizer, diluted to half strength, every two to four weeks. Reduce or cease fertilization during fall and winter.
Pruning
Pruning helps maintain the plant’s shape, size, and encourages bushier growth. Remove any yellowing, damaged, or dead leaves cleanly at the stem with sterilized shears. Trimming leggy stems promotes a more compact plant.
Repotting
Repotting is necessary when the plant becomes root-bound, indicated by roots growing out of drainage holes or circling the pot. This occurs every one to two years, depending on growth rate. Choose a container one or two inches larger than the current pot, and use fresh, well-draining soil mix.
Propagation Methods
Propagating Philodendron Narrow Leaf is commonly achieved through stem cuttings. Select a healthy stem section with at least one node, where new roots and leaves emerge. Cuttings can be rooted in water or moist potting mix.
For water rooting, place the cutting in a clear container with filtered water, submerging the node. Change the water every few days. Roots typically form within weeks; once several inches long, transfer to soil. For soil rooting, plant the cutting directly into a small pot with a well-draining, airy mix, keeping the soil consistently moist. Placing the pot in a warm, humid environment, such as under a plastic bag, enhances rooting success.
Common Issues and Solutions
Philodendron Narrow Leaf plants can encounter common problems, often linked to environmental factors. Yellowing leaves, especially on older foliage, signal overwatering or insufficient drainage. Adjust watering frequency and ensure adequate drainage. Brown, crispy tips or edges usually indicate low humidity or underwatering. Increase atmospheric moisture or water more consistently.
Stunted growth and small leaves, particularly if foliage is deep green, often point to insufficient light. Move the plant to a brighter location with indirect light for more vigorous growth. These plants can occasionally attract common houseplant pests like spider mites, mealybugs, or scale insects. Regular inspection and prompt treatment with insecticidal soap or neem oil manage infestations.
