i used to treat for a big outfit, now i have started my own mowing gig. i really like the treatment aspect of lawncare and have had some of my customers that i mow for ask for lawn treatments. i dont have the equip i used before- i.e. large tank sprayers, nice lesco back back sprayers, a perma green, etc. and Im running on a real limited budget since i just got started this year would hardware store chems be ok to get started on my first couple rounds of treatment??? for the first round i tried the lesco granular weed and feed. i spread it with a vigoro broadcast spreader i bought at a hardware store, and really i dont think it will be very effective. what would be the most effective and affordable way to treat lawns that vary from thin but not too weedy- to lawns that are 75% weeds???
