Agway Greenlawn Fertilizer

This ratio focuses on potassium (20%) rather than phosphorus or high nitrogen. Potassium is essential in the fall because it strengthens the grass's cellular structure, helping your lawn better tolerate cold temperatures, frost, and winter stress.

It is generally recommended to wait until new grass has been mowed at least two or three times before applying this fertilizer. Applying it too early to delicate seedlings can potentially burn them due to the concentrated nutrient content.

Slow-release fertilizers provide a steady, consistent supply of nutrients over an extended period rather than a quick burst of growth. This ensures your grass roots are fed gradually as they prepare for dormancy, rather than forcing top growth that could be damaged by early cold snaps.

For even distribution, use a broadcast spreader set to the recommended rate on the bag. Apply it to a dry lawn, and then lightly water the area afterward to help the granules settle into the soil and begin the nutrient release process.

While this is a synthetic fertilizer, it is standard practice to keep pets and children off the lawn until the granules have been thoroughly watered in and the grass has completely dried. Always check the specific safety instructions on the product packaging for the most accurate guidance.
