How to Add Water Retaining Crystals to Plant Containers

Water retaining or absorbing crystals help retain the moisture in the soil of container plants or hanging baskets. They will release this water gradually and keep the soil moist longer. This approach may or may not be suggested on the packaging of the water crystals you're purchasing. The benefit of this approach is that adding water to the crystals before adding them to the soil gives a better end result for newly potted or repotted plants.


  1. 1
    Check that the potting mix you're using doesn't already contain the crystals. It's wasteful adding more!
  2. 2
    Measure the amount needed. Follow the instructions on the packaging as to the amount in relation to your container size. Pour this amount into a mixing bowl.
  3. 3
    Add the recommended amount of water. Stir through to distribute the crystals.
  4. 4
    Wait. The crystals will absorb the water and expand into a gel sort of texture.
  5. 5
    After about 15 minutes of this absorption process, tip the crystals into the potting mix. Mix to distribute evenly.
  6. 6
    Start adding to the containers for planting. Plant the plants as usual.
