We’ll be getting into our final rotation of lawn fertilization and weed control so I wanted to take a moment to review the logic and value of fall fertilization and how it helps your lawn come back even stronger in the spring. As temperatures cool, grass is busily absorbing moisture and nutrients while storing energy for the long period of dormancy during the winter. While the grass may seem to be growing more slowly, below ground is where the action is taking place as it’s need for nutrients is just the same as spring. It’s just allocating its energy to the root system, not the visible blades. In fact the root system is the most important part of maintaining a green and healthy lawn for the next season.
While fall may seem like the beginning of the long winter reprieve from mowing and watering, most lawn experts encourage to keep up a watering and mowing schedule until the ground freezes.
As the season draws to a close, consider lowering the mower’s blade to its lowest setting for the last cutting of the year. That will allow more sunlight to reach the crown of the grass, and there will be less that can turn brown during the winter. An important exception would be not to lower the blade to the point that it’s trimming more than third of the blade at any one time. Lowering the mower blade gradually is a sure way to not take off too much at any one time.
A fall aeration will also provide similar benefits as a spring aeration and is also recommended. Renting an aerator is a possibility but most of your local lawn services will offer a price that is cheaper than renting an aerator yourself. The plugs will generally be between 1 to 2.5 inches and make sure to mark any sprinkler heads.
