When do you really think it is too late to apply fertilizer in the spring? I have plenty of grass and doing rotational grazing. I didn't get my soil test result back as quick as I hoped and now I think if I fertilized I would be wasting my money as fescue will slow down here in month or so. I am thinking I would be better off to wait til fall and try to stockpile fescue for winter... Any thoughts or experience?
