Pretty excited. Just passed my test now have my operator/applicator liscense. I only plan to treat my yard and two rental properites that I own until I learn enough to understand the spraying business. I know pre emergent should be put down soon but not sure what to buy or use. Also not sure on the time of applications that most lawn companies use for the rest of the season. Any help would be greatly appreciated especially on the best products to use for pre emergent, broadleaf weed control and fertilizer. Any help is greatly appreciated.
