The `Philodendron lynamii` is a sought-after plant known for its distinctive appearance and tropical allure. This aroid, part of the Araceae family, is a desirable addition to any indoor plant collection.
Identifying Philodendron lynamii
Philodendron lynamii stands out with foliage that transforms as it matures. New leaves emerge vibrant red or deep pink, gradually shifting to a rich, glossy dark green. This color change is a key characteristic.
The leaves are large and heart-shaped. The plant exhibits a scrambling or terrestrial crawling growth habit, rather than strictly climbing. Originating from Peru, this philodendron thrives in the tropical understory, reaching up to three feet indoors.
Essential Care Requirements
Light Needs
Philodendron lynamii thrives in bright, indirect light. Place the plant near an east or south-facing window, where light is dappled. Direct sunlight can cause foliage to yellow, pale, or scorch. If natural light is insufficient, a grow light can supplement its needs.
Watering Practices
Philodendron lynamii tolerates slight underwatering better than overwatering due to its thick, moisture-storing leaves. Allow the top one to two inches of potting mix to dry out before watering. Frequency varies seasonally; summer may require water two to three times a week, while winter reduces to once every two to three weeks. Use lukewarm, chlorine-free water, as cold or chlorinated water can hinder growth and cause leaf damage. Ensure the pot has drainage holes to prevent waterlogging and root rot.
Humidity and Temperature
Humidity
This philodendron prefers moderate to high humidity, ideally 60-90%, for vigorous growth and vibrant leaf color. While it tolerates humidity as low as 40%, excessively low levels can cause leaf margins and tips to brown. Increase humidity using a humidifier, pebble tray, or by grouping plants. Misting offers temporary relief, but ensure proper ventilation to prevent fungal issues.
Temperature
Philodendron lynamii thrives in warm environments, with an ideal range of 60-78°F (15-26°C). It is not cold hardy; avoid freezing temperatures or prolonged periods below 50°F (10°C), which can stunt growth or cause death. While it tolerates higher temperatures up to 90-95°F, regular watering is necessary to prevent dehydration. Maintain consistent temperatures without extreme fluctuations.
Soil Mix
A well-draining, loose, and airy potting mix rich in organic matter is best for Philodendron lynamii. An ideal blend includes components like orchid bark, perlite, sphagnum moss, coco coir, and charcoal. This composition allows for easy drainage, prevents waterlogging, and ensures good air circulation around the roots, reducing the risk of fungal infections like root rot. The plant prefers a slightly acidic to neutral pH level, between 6 and 7.
Fertilization
During its active growing season in spring and summer, Philodendron lynamii requires regular fertilization. A balanced liquid fertilizer (e.g., 20-20-20 or 3-1-2 ratio), often diluted to half strength, is suitable. Fertilize every 2-6 weeks. The plant also needs micronutrients like calcium and magnesium for healthy foliage color. During fall and winter dormancy, reduce or stop fertilization entirely to prevent root burn.
Propagating and Repotting
Propagating
Propagate Philodendron lynamii using stem cuttings, ideally during summer. Select a healthy stem section 4-6 inches long with at least one node. Remove lower leaves. Allow the cut end to callous overnight, and consider dipping it in rooting hormone. Plant the cutting in a moistened, well-draining potting mix, keep it in bright, filtered light, and maintain consistently moist soil until new growth appears.
Repotting
Repotting is needed when the plant outgrows its container, indicated by roots circling the pot or emerging from drainage holes, or when growth slows. This often occurs every two years, or when the soil mix degrades. Choose a new pot about two inches larger in diameter with adequate drainage. Gently remove the plant, inspect roots for damage, and place it in the new pot with fresh, well-draining aroid mix at the same depth. After repotting, water thoroughly and place the plant in bright, indirect light to minimize transplant shock.
Troubleshooting Common Problems
Yellowing Leaves
Yellowing leaves on Philodendron lynamii often relate to improper watering or excessive direct light. Overwatering, leading to root rot, causes leaves to yellow and become mushy. Conversely, prolonged underwatering also leads to yellowing. Brown tips or margins suggest insufficient humidity. Adjusting watering and increasing ambient humidity can resolve these symptoms.
Pests
Pests like spider mites, aphids, mealybugs, and scales may affect Philodendron lynamii. Regular inspection of new growths, stems, and leaves helps in early detection. For small infestations, wipe affected areas with a cotton ball dipped in 70% isopropyl alcohol, especially for mealybugs and scales. Addressing environmental stressors, such as low humidity, can make the plant less susceptible to pests.
Safety Considerations
Like many plants in the Araceae family, Philodendron lynamii contains calcium oxalate crystals, which are toxic if ingested. Ingestion by humans or pets can lead to immediate pain and swelling of the mouth, tongue, and throat, excessive drooling, and difficulty swallowing. Keep the plant out of reach of children and pets, and wash hands after handling.
