Fall Aeration is Important for Healthy Lawns

Oct 25, 2021


Mid-to late October is the most crucial time of year to aerate your lawn. This time frame is best as the temperatures have cooled and weed pressure is minimal. The process of aeration involves creating holes down in the soil so that water and nutrients can reach the grass roots. It also helps to remove excessive thatch from your lawn, which is a layer of roots, stems, and organic material that inhibits water penetration.
 
Why is it so important to aerate in the fall? Over the summer, your soil can easily become compacted from hours of outdoor summer activities. Compact soil prevents roots from growing effectively as they are unable to establish a deep system and are therefore easily impacted by drought and other weather elements. Water and fertilizer may also have a hard time reaching the roots, depriving the grass of necessary nutrients. Aeration can help relieve this problem by allowing the soil to relax and expand into the vacated core, improving grass resiliency and overall health.
 
You can aerate your lawn yourself or hire a lawn service professional to do it for you. Plug aerators are the preferred choice of many lawn care professionals. These machines use rows of hollow tines that remove plugs of soil from your lawn and deposit them on the surface where they quickly break down. Most aerator machines provide basic operating instructions for the specific model, but the process is similar to mowing as you work back and forth across your lawn.
 
Right after you aerate is the perfect time for overseeding and fertilizing. By adding new grass seed to your lawn during the fall, you can thicken up bare patches and damaged areas before the grass goes into dormancy. This will ensure a lush, beautiful lawn with less effort in the spring.
 
Your soil condition is key to maintaining a healthy lawn, so don’t neglect to aerate at least once a year to prevent soil compaction. Your local Co-op can help you find the right tools for the job and can give you recommendations on the best grass seed to use. Find the nearest location here.
