I need help on what I can do to help eliminate some of the summer broadleaf weeds on 2.5 miles of pinestrawed berms. The berms are about 8ft high with Wax Myrtles, Ligustrims and Loropetalums. Using Pine Straw as the ground cover. About 5500 bales of pine straw will be laid in March. I have never applied a pre over old Pinestraw before and I’m not sure of its effectiveness. Also the price of doing this isn’t in the contract and I will have to eat it all. However if I could save on spraying Gly throughout the season that should help offset that price a little. Even if I did this in only the areas that are the worst for weeds it may help or am I just stuck spraying Gly every week or 2 throughout the summer?
