Seasol Lawn & Turf Starter, Seasol for Lush Green Lawns and Seasol for Buffalo Lawns are all liquids, which are readily absorbed into the lawn and the soil. Therefore you do not need to water them in.
If you are treating your soil with Seasol Super Soil Wetter and Conditioner, please ensure that you do wash it off the foliage, to prevent burning.
PowerFeed Lawn Feed and PowerFeed Buffalo LawnFeed are all granular products and sit on top or just below the lawn and soil. As they contain microbes, they need to be watered in thoroughly applications, to get those microbes working.
