These Yates water crystals are like insurance for your plants, should the soil or your pot ever dry out. A teaspoon of this stuff, mixed with 750ml of water will hydrate the tiny crystals, swelling them to hundreds of times their size. Plant roots grow through these crystals and take out water as they need. Add a slop into the bottom of the planting hole – this stuff is ideal to use in pots AND in soil. These water crystals will rehydrate themselves with each watering, meaning that this stuff will last several years before biodegrading harmlessly. Using Yates Waterwise Water Crystals will allow plants to tolerate drier weather conditions – perfect for the summer months in Australia.
