As a houseplant, Monstera philodendron does best in bright light in summer and direct sun in winter. It can be grown under florescent light, but will not develop the leaf perforations when light is inadequate. It prefers warm room temperature and medium to high humidity, but is fairly tolerant of a wide range of conditions once acclimated. Plants do not grow below 50F and frost will kill them.
Water thoroughly and allow the soil to dry slightly between waterings. Plants kept on the dry side will have slower growth. Water less in winter. Fertilize regularly from spring until fall. The leaf edges will turn brown if humidity is too low. Wipe the dust from the leaves periodically.
Container-grown plants need frequent repotting to accommodate the root system.
Grow Monsteras in a rich soil mix. They can be very vigorous growers and need support to keep the stems from breaking. Provide a moss-covered support sunk into the pot for the aerial roots to attach to. When watering make sure to also water the moss-covered support so the aerial roots can obtain water and nutrients.
The plant contains oxalic acid, so all parts are poisonous except the ripe fruits.
