How to Prune Anthurium

By Barbara Fahs ; Updated September 21, 2017
The anthurium is a popular tropical cut flower.

Anthuriums are exotic tropical flowers that are grown in Hawaii and other warm climate areas to supply the cut flower industry around the world. The typical anthurium has large red, heart-shaped blossoms with a prominent stamen. However, many different cultivars exist and flower color ranges from white to green to violet. Anthurium leaves are also heart-shaped and add to the attractiveness of floral arrangements. This flowering plant does well outdoors in shaded areas of the tropics and indoors as a houseplant in other climate zones. A little pruning will help your plant to thrive and produce flowers.

Prune your anthurium at any time of year. According to the U.S. Department of Agriculture, commercial anthurium growers use a number of different leaf pruning strategies.

Cut all but three or four of the largest, healthiest leaves to the base of their stems, using your clippers. Compost the leaves or use them in a soil mix to grow other anthuriums.

Trim spent flowers down to the base of their stem. Also cut fresh flowers to their base for floral arrangements.

Cut off dead and dying leaves and those that become damaged from insects or other pests as soon as you notice them in order to allow your plant to focus its energy on producing new, healthy leaves and a maximum number of flowers.

 

Things You Will Need

  • Garden clippers
  • Bleach
  • Water

Tips

  • The University of Hawaii College of Tropical Agriculture reports that winter is the time when the floral industry needs the largest number of anthuriums, but summer is when they are at their peak production.
  • You can use chopped up anthurium leaves in a growing medium that is conducive to anthuriums by combining then with topsoil, eucalyptus bark, manure, sugarcane bagasse and other organic ingredients.
  • You can achieve maximum flower production if you grow your anthuriums close together and prune heavily to allow for good air circulation, which helps to prevent plant diseases.
  • You can cut off part of the stem after you harvest the flowers if it is too long for your vase--do not leave part of the stem on the plant.

Warning

  • Some anthurium cultivars are subject to the fungal disease known as anthracnose. If your plant has any dead spots on the flowers, leaves or stems sterilize your clippers between cuts with a solution of one part chlorine bleach and nine parts water.
