Most varieties of philodendron grow well with lower levels of light. In fact, direct sunlight may cause sunburn spots on philodendron leaves. Ideally, keep the plants in an area of indirect or curtain-filtered light, with a mix of fluorescent and incandescent light if you are growing them indoors.
Water philodendron plants frequently to ensure that the soil is kept moist but not soggy. Never allow a philodendron to sit in water. Signs of insufficient light or overwatering of philodendron include yellowing of lower leaves and leaf drop.
