The Shangri La plant (Thaumatophyllum bipinnatifidum ‘Shangri-La’, often sold as Philodendron ‘Shangri-La’) is a popular indoor plant. Native to South America, this tropical plant has a lush, bushy appearance due to its dense, upright growth. Its deeply lobed, green leaves with serrated edges become more pronounced as the plant matures. It is generally considered an easy-care plant, suitable for both new and experienced gardeners.
Providing Optimal Growing Conditions
Establishing the right environment is fundamental for the health and robust growth of a Shangri La plant.
The Shangri La plant thrives in bright, indirect light, similar to the dappled sunlight it would receive in its native South American rainforests. Placing it near a south or west-facing window, diffused by a sheer curtain, is often ideal. While it can adapt to lower light, very dim environments may result in leggy growth and slower development. Direct, harsh sunlight can scorch its leaves.
Consistent moisture is important, but the plant should never sit in waterlogged soil to prevent root rot. Water the Shangri La when the top two inches of soil feel dry. Watering frequency changes with seasons; water more often during active growth in spring and summer, and reduce watering in fall and winter. If the leaves droop or curl inward, it often signals a need for water.
A well-draining, airy potting mix is essential for Shangri La plants, allowing for proper aeration around the roots and preventing excessive moisture retention. An ideal mix combines regular potting soil with coco coir for moisture retention, perlite for drainage, and organic compost for nutrients.
Shangri La plants prefer moderately warm conditions, ideally between 60°F and 75°F (16°C-24°C). Temperatures below 50°F (10°C) can harm the plant, so protect it from cold drafts. It appreciates humidity levels above 50%, though it tolerates 30-50%. To increase humidity, consider:
Placing a tray of water and pebbles near the plant.
Grouping it with other plants.
Using a humidifier.
During active growing seasons (spring and summer), fertilize monthly with a balanced, water-soluble liquid fertilizer diluted to half strength. This prevents over-fertilization and salt buildup. Reduce or cease feeding in fall and winter when growth slows. Always apply fertilizer to moist soil to avoid burning the roots.
Ongoing Care and Maintenance
Routine care and maintenance contribute significantly to the Shangri La plant’s appearance and vigor.
Pruning is minimal, primarily involving the removal of yellowing, brown, or dead leaves to maintain its health and appearance. Use clean, sharp scissors or shears to make cuts as close to the main stem as possible. Its compact, shrub-like growth habit means extensive shaping is rarely needed.
Repotting is necessary when the plant outgrows its container, typically every one to two years, indicated by roots emerging from drainage holes or circling the pot. The optimal time is spring or early summer when the plant is actively growing. Choose a new pot only one to two inches larger in diameter with adequate drainage.
During repotting, carefully remove the plant and gently loosen compacted soil around the roots, inspecting for damage. Plant it in fresh, well-draining soil, firming the mix to eliminate air pockets. Water thoroughly until water drains freely.
Propagation is commonly done through stem cuttings or root division. For stem cuttings, cut a healthy stem below a node, ensuring it has leaves. This node is where new roots will emerge. Cuttings can root in water or moist potting mix; once established, transplant them to soil. Larger plants can be divided at the roots during repotting, separating established clumps.
Addressing Common Issues
Even with proper care, Shangri La plants can occasionally encounter issues. Recognizing symptoms and understanding their causes helps in swift resolution.
Shangri La plants can be susceptible to common houseplant pests like spider mites, mealybugs, aphids, and scale insects. Regularly inspect the plant, especially leaf undersides. Treat affected areas by wiping with a damp cloth or applying insecticidal soap or neem oil. Good air circulation and clean leaves help deter pests.
Diseases are less common but often stem from improper care. Root rot, a frequent concern, results from consistently waterlogged soil due to overwatering or poor drainage. Symptoms include yellowing leaves and stunted growth. Prevent root rot by ensuring proper drainage and allowing topsoil to dry between waterings.
Yellowing leaves can indicate overwatering or insufficient light; adjusting light or watering often resolves this. Brown leaf tips often point to low humidity or inconsistent watering. Increasing humidity or maintaining consistent soil moisture helps alleviate these problems.
