There are many different kinds of philodendrons including upright and hanging varieties but all take the same basic care.
Place in a bright location with indirect light avoiding direct sunlight. Philodendron scandens (heartleaf philodendron) can tolerate low levels well.
Keep soil moist at all times but don’t let the plant sit in water. Water more sparingly in winter keeping soil just moist. Mist leaves regularly. Push aerial roots into the soil on climbing varieties.
Average warmth, but no philodendron likes going below about 12℃ for long.
Slow-release pellets in the beginning of the growing season or weekly liquid fertilizer.
Some of the philodendron varieties are extremely fast-growers, especially the climbers. Pinch off the new growth to keep the plant manageable and repot annually as needed. Repot in a rich, loose potting media. Use a moss stick or other support for the climbing types.
