Philodendron Dark Lord is a rare and exotic plant that requires special care to thrive. Even a small Dark Lord can grow into a fairly large plant. This plant prefers bright, indirect light, avoid direct sunlight to avoid burning its leaves. It can also tolerate medium light conditions but will not grow as well. As for watering, check the soil regularly for dryness by sticking a finger into the top inch of soil and water it when the soil feels dry to the touch. Make sure to drain the water well and avoid overwatering to prevent root rot. Use a rich, well-draining potting soil with bits to oxygenate the roots. Fertilize the plant once a month during the growing season with a balanced, water-soluble fertilizer. For humidity, it prefers a high level of around 80%, you can increase the humidity by placing a humidifier nearby or grouping the plant with other plants. It also tolerates average humidity levels. Repot the plant every 1 to 2 years or when it becomes cramped. Propagation is by node cuttings, rooting them in water or sphagnum moss. Trim off yellow or brown leaves as they appear and prune the plant to control its size and shape. Philodendron Dark Lord can be grown outdoors in USDA hardiness zones 10b to 11b. By following these care tips, your Philodendron erubescens plant should thrive and continue to beautify your space.
