Answer: You will notice results with each individual application. The degree of results is determined by varying circumstances of each individual lawn or turf site. For example, perinneal weeds are more difficult to gain control than annual weeds, hence perinneal weeds may require 1 or 2 more treatments before we gain control. Another example would be if the lawn or turf site is suffering from compaction or low PH it may take a full season or two to see changes in turf density.
