Now that the cooler weather is here, It is a good time to go ahead and apply a granular weed and feed to your lawn. The cooler weather and shorter days will keep the weed killer from affecting the lawn. Highly suggest that you use a slow release water soluble fertilizer. This minimizes run off and contamination of the aquifer. Don’t forget to water the fertilizer in well after applying. Best way to apply is when the grass is slightly damp so the weed killer will stick to the leaves.
