Fall is the most important time to fertilize your lawn as the fall morning dew delivers moisture to help the turf absorb the fertilizer. In addition, the grass has a chance to build stamina before a cold winter. Lastly, the supporting root growth in fall leads to a healthier, greener lawn in spring. This is a great time for root growth as 70% of growth takes place in the fall.

Lawns also improve air quality, reduce heat by 20 to 30 degrees, and generate oxygen. So, therefore, we need to ensure the lawn stays healthy.

Question You May Ask About Fertilizing?

Should you mow first or after an application of fertilizer?

Mowing is an integral part of a healthy lawn. You should wait 3 to 5 days after an application has been applied before mowing.

Should I rake the leave before an fertizer application?

The most important thing to prepare your lawn for the fall fertilizer is to rake your leaves. Once the leaves start falling, it is essential to remove them from your lawn at least once a week. When you fertilize you do not want any leaves on the ground, as it can obstruct the fertilizer from reaching the soil. For example, grassroots are still growing in the fall and it will smother the grass when it’s trying to grow. Having leaves on the ground over winter will encourage fungus in the spring when the snow melts.

When is the best time to fertilize and water the lawn?

The best time of day to fertilize and water the lawn is in the morning. Therefore, it stands to reason that late evening is not a good time to fertilize, as it might be too cool, and could help develop and spread fungus throughout the lawn. Fertilizer needs water for it to activate, so it is essential that you water. If it rains after you have fertilized, that would be an added benefit.
