How to Grow Anthurium Indoors

Keep anthuriums in a room where the temperature remains above 70 degrees Fahrenheit. Avoid locations near air vents and drafty doors and windows where the plant is exposed to lower temperatures during the winter.

Provide the anthurium with all-day indirect sunlight. Anthuriums need at least six hours of bright light, but direct sun can cause leaf scorching. An area near a south-facing window or a brightly lit window with a sheer window covering provides sufficient light.

Water the plant every five to 10 days, or when the soil has nearly dried. Water thoroughly until the soil is completely moistened and then allow it to dry again before the next watering.

Fertilize the anthurium every other month. Use a soluble, high-phosphorus fertilizer, such as a 1-2-1 ratio blend, at half the package recommended rate.

Repot the anthurium after the roots completely fill the current container. Transplant into a pot one size larger than the current pot. Use a peat-based, well-draining potting mixture.
