Is there a particular season that is optimal for applying these products to ensure maximum efficacy? Should I consider the specific climate conditions in my area, such as temperature fluctuations and rainfall patterns, before deciding on the timing? Furthermore, how do various grass species react to weed and feed applications at different times of the year?
