Watering Using Capillary Matting

Watering Using Capillary Matting

Capillary action or ‘wicking’ is the upward movement of a liquid via a surface such as from one bit of compost to another.

These Poinsettias have been placed on a micro perforated matting that allows water to be taken up by the plants in a capilliary action. From the mat the water is slowly drawn up to the pot and soil in the pot to water your plant.

It is a simple process to water the matting, set up a dripfeed system or syphon and the plant will then take up what it needs.

Benefits and Tips on Capillary Mats

  • Water is taken up at the temperature of the matting so you avoid the shock of cold water.
  • Plants shouldn’t become water logged as the capillary process slows as soil become wet.
  • A bed of wet sand can be used as your own home made capillary watering system
  • Advantages of capillary action include plants with delicate leaves not being damaged by the overhead watering and an even supply of water being consistently available.

Tips for ‘Wicking’

  • Matting works best when laid on a flat surface. My greenhouse bench has a large tray with a capillary mat inside.
  • Do not expect totally dry plants to take up moisture. If they are bone dry give them a soaking first.
  • Buy matting like this from amazon
