How to Induce an Anthurium Red Plant to Grow Slower

The tropical red anthurium has eye-catching blooms. Large heart-shaped petals surround a white center spike in one of the most common varieties, and cut blooms can last for a month. Anthurium plants can be grown in pots in warm climates, though they are susceptible to blight and root rot in wet soil. To have anthurium blooms peaking at the right time or to control plant size, you may need to induce slower growth.

Instructions

- 1
  Extend the anthurium's winter dormant period by keeping it in dry conditions at temperatures between 50 and 60 degrees for two months or more. Dormancy is a natural way to slow a plant's growth.
- 2
  Reduce the amount of water received by the plant. Anthuriums have root systems that rot when exposed to constant or excessive moisture, so allow the soil to dry between waterings. Depriving the plant of water for a slightly longer period of time, such as one extra day, will result in slower growth.
- 3
  Prevent indirect sunlight from reaching the plant for more than two hours a day. Maintain the anthurium in a pot and move it from a porch or sunny windowsill to an interior room every day. A reduction in light will slow the process of photosynthesis, and the lack of sugar production will curb plant growth.
