When is the correct time to apply Weed Free Zone for wild violets in Fescue?
I'm wanting to spray my yard to kill the weeds off this fall. Is it too late to use this in central Indiana? I did this a few weeks ago but the wild violets survived! Should I increase the mixture to kill these? I have bluegrass, fescue mix grasses.
According to the Fertilome Weed Free product label: Spring and Fall treatments under adequate soil moisture conditions are preferred to the Summer treatments. Generally, Summer broadcast applications to older, drought stressed weeds are less effective. Broadcast (entire areas) applications or follow-up applications at 2-6 week intervals are recommended for more mature Weeds, for dense infestations, and for adverse environmental conditions. Spot treatments during summer may be appropriate for sparse infestations, or as a follow-up treatment, or any time broadleaf weeds are susceptible. For more specific information or application tips we recommend that you contact the manufacturer directly. You can reach VPG at 888-583-5296.
