Chickweed turned yellow but a lot still green and thick. Sprayed 21 days ago
According to the product label, a sequential broadcast applications or follow-up applications as spot treatments at 30 days are recommended for more mature weeds, for dense infestations, and for adverse environmental conditions. Spot treatments during the summer may be appropriate for sparse infestations, or as a follow-up treatment, or any time broadleaf weeds are susceptible. Apply on a spray to wet basis for the best results.
