The Philodendron angustialatum is a captivating plant known for its striking foliage and tropical origins. Native to the lush rainforests of South America, particularly Brazil and Peru, this species brings an element of the exotic into indoor spaces. Its appearance is characterized by elongated, often pointed, dark green leaves that can develop a subtle wrinkled texture.
Philodendron Angustialatum Care
Light Needs
Philodendron angustialatum flourishes in bright, indirect light, mirroring the dappled sunlight it receives under the rainforest canopy. Placing it near an east or west-facing window is ideal, as these locations provide gentle morning or late afternoon sun without harsh intensity. Direct sunlight can lead to leaf burn and yellowing, while insufficient light may cause the plant to become leggy with smaller, paler leaves.
Watering Practices
Maintaining proper soil moisture is important for the health of Philodendron angustialatum. The plant prefers its soil to be consistently moist but not waterlogged, as excessively wet conditions can result in root rot. It is advised to water when the top one to two inches of soil feel dry to the touch. Allowing the plant to sit in standing water should be avoided by ensuring proper drainage and discarding any excess water from the saucer. Signs of improper watering include yellowing or browning leaves, which can indicate either overwatering or underwatering.
Ideal Soil Mix
A well-draining, airy potting mix that provides good aeration is important for Philodendron angustialatum. Components like perlite, orchid bark, and coco coir can be added to a standard potting mix to improve drainage and prevent compaction. The ideal soil pH for philodendrons falls between 5.0 and 6.0, indicating a slightly acidic preference.
Temperature and Humidity
Philodendron angustialatum thrives in warm and humid conditions, reflecting its tropical origins. An ideal temperature range for this plant is between 65°F and 85°F (18°C to 29°C), though it can tolerate slightly cooler temperatures. Temperatures below 55°F (13°C) can cause stress, leading to leaf discoloration. High humidity is also beneficial, with levels around 60-70% being favorable. To increase humidity, consider grouping plants, using a pebble tray with water, or employing a humidifier.
Fertilization
During its active growing season in spring and summer, Philodendron angustialatum benefits from regular fertilization. A balanced, water-soluble fertilizer formulated for tropical plants is recommended. Dilute the fertilizer to half strength to prevent over-fertilization and leaf burn. Fertilization can be done once or twice a month during warmer months, reducing or stopping entirely during the colder, dormant season.
Propagating Philodendron Angustialatum
Propagating Philodendron angustialatum is a straightforward process, most commonly achieved through stem cuttings. Select a healthy stem with at least two leaves and a node, which is a small bump where roots will emerge. Using clean, sharp shears, make a cut just below a node.
Place the cutting in water, changing it every few days until roots are at least an inch long, then transplant to soil. Alternatively, plant the cutting directly into moist potting mix with the node beneath the surface. In both cases, ensure a warm spot with bright, indirect light for root development.
Common Problems and Solutions
Philodendron angustialatum can encounter certain issues, even with consistent care. Pest infestations are possible, with common culprits including spider mites, mealybugs, aphids, thrips, and fungus gnats. Inspecting the plant regularly for signs of pests, such as webbing or sticky residue, allows for early intervention. Treating these pests involves using insecticidal soap, neem oil, or manually removing them with rubbing alcohol.
Beyond pests, other leaf problems can arise. Brown leaf tips or edges, especially if accompanied by a crisp texture, might indicate low humidity or underwatering. Increasing ambient humidity around the plant can help address this. Yellowing leaves not due to watering issues can sometimes point to a nutrient deficiency, particularly of nitrogen, iron, or magnesium. In such cases, a balanced fertilizer can provide the necessary nutrients.
