Does Milorganite need to be watered in to work?
No, it is not necessary to water in Milorganite for it to work. That is because Milorganite does not contain any soluble salts (which can burn turf) but relies on natural microbes in the soil to break down nutrients. Watering in Milorganite will ensure that the fertilizer achieves soil contact earlier and speed up the fertilizing process, but it is not necessary. Please refer to the Home Use or Professional Use sections for application information.
