Time sort of got away this fall and I forgot to put down the fertilizer. I believe I have some grubs at work but not too bad a case so given the optimum time is mid-summer, or so I read, I suppose that can wait. Would an application do any good at this point in upstate NY and if so, what mix would be best? Since I need to cover about two-three acres of grass a mistake can be expensive. I do have the ability to spray as well as use granular.
