Earthcare Water Crystals

Earthcare Water Crystals, when incorporated into a soil or potting media, absorb and retain large quantities of water and water-soluble nutrients. Unlike most products that become hydrated, Water Crystals are able to release the absorbed water and nutrients, thereby allowing the plant to have water and nutrients available as needed.

Features and Benefits:

  • Saves water
  • Aids plant establishment
  • Improves transplant survival rates
  • Lasts up to 5 years in the soil


  • Water Crystals 10kg 10Kg Bucket
  • Water Crystals 25kg 25Kg Bag

Water crystals are made of super absorbent anionic polyacrylamide that is insoluble in water.  However, they have the ability to absorb up to 500 times their weight in water with 95% of this water and nutrient being readily released again for the plant to take up as needed.  The crystals rehydrate with any rain or irrigation and remain effective for to up to 5 years.

Water crystals can be placed directly into the planting hole or incorporated into the backfill surrounding the root ball; under turf or simply broadcast over the top of the prepared planting surface.
