How to Grow Anthurium in Pots

Place anthuriums near a window so they receive diffuse light to ensure the healthiest leaf growth. Keep temperatures between 65 and 72 degrees Fahrenheit and avoid placing the potted plant in drafty areas near air vents or open doors.

Water potted anthuriums when the top 1/2 inch of soil feels dry during the active spring and summer growing season. Reduce watering in winter to when the top 1 inch of soil feels dry. Water the soil until water drips from the bottom of the pot, then empty the drip tray 30 minutes after watering. Spread a 1/2-inch layer of sphagnum moss over the soil surface to help retain moisture between waterings.

Fertilize anthuriums once monthly during the growing season with a soluble houseplant or all-purpose fertilizer, such as a 24-8-6 blend. Mix 1/2 teaspoon of the fertilizer with 1 gallon of water in a watering can and irrigate the soil with the solution.

Mist the leaves with lukewarm tapwater in a spray bottle daily, especially during the dry winter period. Misting raises humidity, resulting in a healthier anthurium, while also rinsing away dust particles. Outdoor potted plants require misting only during dry weather or if the foliage becomes dusty.

Transplant the anthurium to a pot one size larger than the current container every one to two years in spring. Combine equal parts potting soil, peat and perlite in the container with a bottom drainage hole. Plant the anthurium in the new pot at the same depth it was growing at in the old container.
