Searles Water Crystals are great additions to pots or new garden plantings, especially in dry seasons. These crystal-shaped polymers swell when they come into contact with water, storing up to 400 times their own weight in water plus soluble nutrients. Once expanded with water, the crystals become penetrable so your plants' roots can absorb the water within. By adding these crystals to your pots and new planting holes, you'll help to keep water available in your plants' root zone at all times, while also minimising soil nutrient loss through evaporation and drainage. The end result? Happier, healthier plants that actually need to be watered less often, saving you time and effort.
