Per the Fertilome Weed Free Zone label instructions: 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.
