Philodendron Lynamii is known for its distinctive foliage and growth habit. Its new leaves emerge in vibrant shades of red or pink before gradually transitioning to a deep green as they mature. This tropical aroid is native to Peru and Ecuador. The plant exhibits a semi-epiphytic, crawling growth pattern, often scrambling along the ground or using support to grow upwards. As with many Philodendron species, Philodendron Lynamii contains calcium oxalate crystals, making it toxic if ingested by pets or humans.
Essential Care Requirements
Light
Philodendron Lynamii thrives in bright, indirect light. An east or south-facing window provides suitable light, ideally with the plant positioned a few feet away to prevent direct sun exposure. Direct sunlight can scorch leaves, causing them to yellow or become pale. If natural light is insufficient, a full-spectrum grow light can supplement its needs, ensuring even growth by rotating the plant regularly.
Watering
Consistent watering is important for Philodendron Lynamii, but overwatering leads to root rot. Allow the top one to two inches of soil to dry out between waterings before watering thoroughly. While the plant tolerates brief periods of drought, prolonged underwatering causes wilting and browning of leaves. Using lukewarm, chlorine-free water is beneficial, as cold or chlorinated water hinders growth or causes leaf discoloration.
Soil
A well-draining, airy, and rich organic potting mix is ideal for Philodendron Lynamii. A suitable blend includes components like perlite, orchid bark, sphagnum moss, and coco coir to ensure good drainage while retaining adequate moisture. The soil should have a slightly acidic to neutral pH, ideally between 6 and 7, which helps with nutrient absorption and disease prevention. Good drainage is important to prevent waterlogging and root rot.
Temperature and Humidity
Philodendron Lynamii prefers warm, stable temperatures, ideally between 60 to 78 degrees Fahrenheit (18-27°C). It is not cold-hardy and should be protected from temperatures below 50°F (10°C), which can stunt growth or cause decline. High temperatures up to 90-95°F can be tolerated with consistent watering.
Moderate to high humidity is beneficial, with ideal levels ranging from 60% to 90%. Low humidity causes leaf margins and tips to turn brown. To increase humidity, use a humidifier, place pebble trays filled with water near the plant, or group it with other plants. Misting offers a temporary boost, but ensure good air circulation to prevent issues.
Fertilizing
During the active growing seasons of spring and summer, Philodendron Lynamii benefits from regular fertilization. A balanced liquid fertilizer, such as a 20-20-20 formula, applied every two to four weeks, is recommended. Dilute the fertilizer to half strength to prevent root burn. Reduce or cease fertilization in fall and winter when the plant’s growth naturally slows down.
Routine Maintenance
Pruning
Pruning Philodendron Lynamii helps maintain its shape, encourages bushier growth, and removes leggy or damaged sections. Remove yellowing, brown, or unhealthy leaves to direct the plant’s energy towards new growth. Use clean, sharp, and disinfected tools for pruning to reduce disease risk. Pruning is best done in late winter or summer when the plant is actively growing.
Repotting
Repotting is necessary when the plant becomes root-bound, usually every one to two years. Signs include roots emerging from drainage holes or the plant appearing top-heavy. When repotting, choose a container only slightly larger than the previous one, ensuring it has adequate drainage holes. Gently remove the plant from its old pot, shake off excess soil, and replant it with fresh, well-draining potting mix.
Propagation Guide
Propagating Philodendron Lynamii is achieved through stem cuttings. Select a healthy stem with at least one leaf and one node, as nodes are where new roots emerge. Cut a four to six-inch section using clean, sharp shears.
Optionally, dip the cut end in rooting hormone to encourage root development. The cutting can then be rooted in water, moist sphagnum moss, or a well-draining soil mix. If rooting in water, change the water every few days to keep it fresh. When rooting in soil or moss, maintain consistent moisture and provide bright, filtered light. Once new roots and a few leaves have developed, after about a month, the new plant can be transplanted into its permanent pot.
Common Issues and Solutions
Philodendron Lynamii can encounter various issues, often stemming from improper care or pests. Yellowing leaves indicate overwatering, underwatering, or nutrient deficiencies. If leaves turn yellow and feel mushy, root rot from excessive moisture is likely, requiring attention.
Brown leaf tips or edges signal low humidity or inconsistent watering. Ensuring the plant receives adequate humidity and consistent moisture helps resolve this. Pests such as spider mites, aphids, and mealybugs may infest the plant. Spider mites create fine webbing and cause stippling, while aphids and mealybugs appear as small insects, often with sticky honeydew. Isolating infested plants and treating them with insecticidal soap or neem oil manages these pests. Bacterial leaf spot, characterized by dark green or tan lesions, may occur; good air circulation helps prevent its spread.
