There are almost 200 species of philodendron, both climbing and non-climbing, but only a few of them are commonly grown as house plants. Native to tropical jungles, the philodendron thrives when provided humidity and temperatures between 75 and 85 degrees F during the day and in the 60s at night. The most difficult part of growing philodendron is finding just the right amount of light for it. Too little sunlight and the leaves will be small while too much sunlight will burn the leaves. Once you've found the right place in your home for the plant, the philodendron is easy to care for.
Water the philodendron when the surface of the soil feels dry when you touch it. Water the plant until the water runs out of the bottom of the pot and allow the top of the soil to dry again prior to watering.
Fertilize the philodendron every four to six weeks with a houseplant fertilizer at the rate suggested on the label.
Provide humidity for the philodendron by misting it with water daily.
Wash the philodendron's leaves periodically to keep the dust in the home from clogging their pores. Use a soft cloth dipped in room-temperature water and wipe both sides of each leaf.
