Philodendrons are a diverse group of plants that boast more than 200 varieties. The most common philodendron has tall, climbing vines with deep, green leaves that are heart-shaped and glossy. This fast-growing plant can quickly climb a pole.
The fiddle-leaf philodendron is another climber with fiddle-shaped, leathery leaves that are a dull olive-green color. The split-leaf philodendron is a large-leafed plant. Its smaller leaves are round initially, but as it grows, it develops holes in its leaves creating a feather-like appearance.
Philodendrons grow in any well-drained potting soil mixture that has sufficient air for root growth. Water frequently enough to keep the soil moist, but not soggy wet, and apply enough water to allow some to drain through the bottom of the container. Discard all excess water.
Philodendrons require fertilizer every four to six weeks. You can use any of the popular soluble houseplant fertilizers, but be sure to follow the manufacturer's recommendations.
Philodendrons grow best in indirect light, but will survive low-light conditions if acclimated. During warmer months, place plants outdoors in the shade. A night-time temperature of 60 degrees Fahrenheit, and day-time temperatures between 70 and 75 degrees are best for philodendrons. However, some varieties may survive temperatures as cool as 50 to 55 degrees for short periods.
