Philodendron Plant Care
Native to tropical environs in the West Indies and Central and South America, philodendron (Philodendron spp.) is viable in U.S. Department of Agriculture plant hardiness zone 11 and is commonly raised as a houseplant. Its 200 varieties can be further classified into two types: vining and self-heading. Vining varieties are climbers, whereas self-heading produce leaves from their base. Older, well-maintained plants flower, with blooms like calla (Zantedeschia spp.; USDA zones 7-11). Philodendrons can survive neglect, but with diligent care they thrive for years.

Healthy Soil
Whether being raised as a houseplant or planted directly in the ground, philodendrons require loose, nutrient-rich and well-drained soil. If soil is not well-drained, several problems can occur, including root rot.

To ensure that soil nutrients are replenished, follow a regular fertilizer schedule. Water-soluble or time-release fertilizers in the form of powders, tablets, liquids or pellets are available; lighter and more frequent feedings are recommended, as overfertilization cause brown disfigured leaves. Indoor plants, which grow in lower-light conditions, require fewer feedings than philodendrons kept outdoors.
