Philodendrons

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. Philodendrons are among the easiest to grow houseplants and a good choice for beginners.

The fiddle-leaf philodendron is a 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 initially rounded; as it grows, it develops holes in its leaves, creating a feather-like appearance.

Growth Requirements:

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. Any of the popular soluble houseplant fertilizers will be effective, but be sure to follow the manufacturer's recommendations.

Philodendrons grow best in indirect light, but will survive low-light conditions if acclimated. Place plants outdoors in the shade during warm summer months. A nighttime temperature of 60 degrees F and daytime temperatures between 70 and 75 degrees F are ideal for philodendrons, although, some varieties may survive temperatures as cool as 50 to 55 degrees F for short periods.
