Ok it's Monday and I was thinking about mowing the yard and putting down a back our granular fertilizer I got at Lowes after I mow tonight. I was going to mow the grass then spray it down with water since it says to apply it when the grass is moist and they use my spreader to apply it. But It's Monday and they are calling for storms on Thursday. Should I apply it how long to wait? It's very unlikely that rain will hold of that long in this area anyways but I was just curious.
