In botany, a wetting agent refers to the process of lowering the water’s surface tension and reduce the size of the droplets in order to enhance moisture content and absorption.

MaximumYield explains Wetting Agent

Wetting agents normally comprise of chemicals that can help water spread more easily across the roots since these substances often have hydrophilic properties. Also known as surfactants, wetting agents are available in most gardening stores. They can also be made at home. Some of the more popular wetting agents include:

  • Yuccah: Like the name implies, this wetting agent is derived from the yucca plant.
  • Sugar and apple cider vinegar mix: The combination of these two substances do not merely act as a wetting agent but has also been shown to help plants thrive. To make this at home, mix one cup of molasses with one cup of cider vinegar in five gallons of water.
  • Dish soap and Sprite: In this case, add half a cup of dish soap to five gallons of water and one can of Sprite. The sugar and acid in the Sprite will enhance water assimilation.
