Marguerite from Hammond, La writes
Scotts Turf Builder Bonus S Southern Weed and Feed 2 is a granule which must be watered in immediately after application, either through irrigation or rainfall. If you are expecting very heavy rainfall, then it is usually best to wait until after rain so that you have better control of the irrigation of the product. With very heavy rain right after the granules are put down, you may get some movement of the active ingredient which can create uneven or sporadic weed control.
