my home has 1/3 acre's worth of naturally present small granite stones with dirt about 1" below that.I just spent 4 days hoeing all the weeds. i bought the above mentioned chemical, made by Montereylawngarden and want to know if i can apply this using one of those "dial 'n' spray" hose-end sprayers. the weed killer's info only lists using a tank sprayer with 3oz in 1-2gals of water for every 1000sq ft, i think. so would a hose sprayer with the mix dial set to about 2 or 3ozs, sprayed onto the same area be a no no or not? it sure would make the application a lot easier. also, regardless of application method, would it help any to go back and just spray water from the garden hose onto the coverage area to better help the chemical get down into the soil a little further? thanks for any advice!
