I myself don't have an applicator license to spray for weeds. Therefore I hire it out on the accounts that want this application. During July the grass turned totally brown due to lack of rain and high heat. No mowing for 3-4 weeks. During that time the company I had previously hired came and sprayed for weeds and fertilized. I would think this was a bad time as nothing was growing to properly absorb anything. Am I wrong in this thinking? Maybe I will just have to look into getting my certification and license myself. Only that there isn't much call for it here in this area.
