How to Make an Anthurium Bloom


Anthuriums are part of a large tropical plant family that has over 800 species. The most common variety has a large, waxy, heart-shaped red flower with a protruding style in the center and dark green, heart-shaped leaves. Most anthuriums originally came from Central and South America, where they grow under tropical rainforest canopies. Their native habitat gives us a clue as to the conditions these flowering plants need: warm weather, rich, loamy soil, moist conditions with high humidity and shade. With just a bit of care, you can make this plant produce lots of beautiful flowers in your home during the summer months.

Making Ant

Step 1

Grow your anthurium in a pot indoors and give it the conditions it favors to keep it healthy and more likely to produce flowers. These conditions include filtered sunlight and a well-drained potting soil, into which you have added peat moss, pine bark and perlite or vermiculite. Anthuriums also need humidity of 70-80 percent and temperatures between 70 and 90 degrees Fahrenheit.

Step 2

Water your anthurium twice each week because they like to be moist, but never soggy, which can result in the main stem rotting.

Step 3

Keep a plant saucer filled with pebbles under your potted anthurium to help keep the humidity high around the plant.

Step 4

Fertilize your anthurium for the first time several months after you plant it. Use a balanced, time-release plant food with an N-P-K ratio of 3:1:2 and mix it to one-fourth strength. Repeat this application every 2-3 months until your plant is 1 year old.

Step 5

Apply a low nitrogen or "blossom booster" fertilizer to your anthurium when it is about 1 year old. You can use a plant food designed for orchids; a good N-P-K ratio is 0-10-10. Repeat this application once each month for the plant's entire blooming sseason, from spring through fall.

Tips and Warnings

  • Do not subject anthuriums to nighttime temperatures under 50 degrees Fahrenheit.
