Already removed heavy moss. Just have some left in agrigate.
You should not use Lilly Miller Moss Out Lawn Granules on or too close to the patio as the Iron in the Lilly Miller Moss Out Lawn Granules will cause staining. The product label states that it should be used on lawns ONLY. You can use 30 Seconds Cleaner on a patio for moss control.
