Can you use a sprinkler to water in Milky Spore Powder?


Milky Spore Powder needs to be watered in to soak the spore into the soil where it will become available to grubs feeding on the roots of grass. If no rain is expected, you can use an oscillating sprinkler for 15 to 20 minutes over the entire treated area. There may still be some white residue but this is chalk used as carrier for the spores. If light rain is expected and it will not be a heavy rain or washout, this can also water the Milky Spore into the soil. Be sure to water the spores in before raking or mowing the lawn.
