About this plant
Philodendrons are popular tropical plants known for their attractive, often heart-shaped leaves. They are commonly grown indoors as houseplants because they adapt well to lower light and add lush greenery to spaces. Some types climb with aerial roots, while others grow bushy. They help clean indoor air and are easy to maintain.

Watering. Water when the top inch of soil feels dry. Avoid letting the plant sit in water to prevent root rot.
Fertilizing. Feed philodendrons every 4-6 weeks during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Reduce feeding in fall and winter.
Philodendrons are tough and easy to care for. They prefer indirect light and moderate watering. Overwatering can cause root rot, so let the soil dry out a bit between waterings. They need occasional feeding and benefit from regular cleaning of their leaves.
