Philodendron lacerum is an attractive aroid known for its deeply lobed leaves. Its unique foliage and relatively straightforward care make it a desirable indoor plant.
Identifying Philodendron Lacerum
Philodendron lacerum is recognized by its deeply lobed leaves, often described as “lacerated” or “toothed.” These glossy green to grey-green leaves can appear slightly darker and more glossy underneath. As the plant matures, leaves can reach up to 20 inches long, with lobes becoming more pronounced. This climbing philodendron exhibits an expansive growth habit. It originates from tropical regions of the Greater Antilles, including Jamaica, Cuba, Dominican Republic, and Haiti, where it grows as an epiphyte or hemiepiphyte, often climbing trees.
Essential Care for Philodendron Lacerum
Light
Philodendron lacerum thrives in bright, indirect light for vibrant foliage and optimal growth. While it tolerates lower light, growth may slow. Place it near a window with filtered sunlight, and avoid prolonged direct sun exposure to prevent leaf burn.
Watering
Water Philodendron lacerum thoroughly when the top one to two inches of soil feel dry. Maintaining consistent moisture in the soil is important, but avoid waterlogging, as standing water can lead to root rot. During its active growing season, consistent watering is preferred.
Soil and Potting
Use a well-draining, airy potting mix for Philodendron lacerum to support healthy root development. A mixture of peat moss, perlite, and potting soil or orchid bark is recommended. The soil should be rich in organic matter and slightly acidic, with a pH between 5.0 and 6.0. Repot when the plant becomes root-bound, indicating its roots have filled the current container.
Humidity and Temperature
High humidity levels are important for Philodendron lacerum, mimicking its tropical habitat. Increase ambient moisture with regular misting, grouping plants, or using a humidity tray. This plant prefers warm indoor temperatures, ideally 18°C to 27°C (65°F to 80°F). It is sensitive to cold drafts and temperatures below 13°C (55°F).
Fertilization
During the active growing season (spring and summer), Philodendron lacerum benefits from regular fertilization. Apply a balanced, water-soluble liquid fertilizer every two to six weeks. Reduce or stop fertilization during fall and winter when growth slows.
Propagating Philodendron Lacerum
Propagate Philodendron lacerum using stem cuttings during the growing season. Cuttings should include a node, a small brown nub where roots can emerge. Cut a section of stem just below a node and place it in water. Once new roots develop, transfer the cutting to a well-draining soil mix.
Troubleshooting Common Issues
Yellowing leaves often indicate overwatering or insufficient drainage; ensure adequate drying between waterings and proper drainage. Brown leaf tips may signal low humidity or underwatering, requiring increased humidity or more consistent watering. Stunted growth can result from inadequate light or nutrients; move the plant to a brighter location and ensure regular feeding. While generally pest-resistant, Philodendron lacerum can be susceptible to spider mites, mealybugs, and aphids. Regularly inspect the plant and treat infestations with insecticidal soap or neem oil.
