Do I Need to Aerate my Lawn in the Fall?
This year has brought a nearly perfect Minnesota summer that has allowed many people to enjoy their outdoors and spend time in their yards. That also means your grass has had many hours of being mowed, walked on, and played on, which are all causes of soil compaction. Compact soil prevents grass from establishing a healthy root system and keeps vital nutrients from reaching the roots. Aeration can help relieve this problem along with others, but does it make sense to aerate in the fall?
The answer is YES! Having your lawn aerated in the fall is the perfect way to allow your lawn to breathe while opening it up to receive fertilizer and moisture before the winter months.
Northern Roots uses an aerate machine to remove a small core of compacted soil, creating holes about 2-3 inches deep. While the cores are not very aesthetically pleasing to see, after mowing and watering, they will disappear, adding nutrients back into your lawn, which will, in turn, give you a healthier, more vibrant lawn.
Core aeration can help make your lawn healthier and reduce its maintenance requirements through these means:
- Improved air exchange between the soil and atmosphere
- Enhanced soil water uptake
- Improved fertilizer uptake and use
- Reduced water runoff and puddling
- Stronger turfgrass roots
- Reduced soil compaction
- Enhanced heat and drought stress tolerance
- Improved resiliency and cushioning
- Enhanced thatch breakdown
Although it is important to aerate in the fall and spring, your grass will be increasing their root zones in the fall to prepare for the winter. A fall aeration treatment will help your lawn survive the winter weather and prepare it for new growth and green-up in the spring.
