Water Storage Crystals 300g
Non-toxic crystal which swells when in contact with water. Used for putting in the ground when planting, particularly when planting during summer or in dry areas. As the plant absorbs the water from the jelly it will dry out into a crystal again. When you water the plant or when it rains, the crystal will absorb the water again.
Application rate: 1 teaspoon per 5 litre pot.
