Aerating, also known as core aeration, is a process that is used to perforate the soil, as well as the thatch layer that may exist, removing a core/plug of the soil depositing it on the surface of your lawn to break down.
Why should I aerate?
Aerating will allow water, air and fertilizer to penetrate all the way down to the root zone. This will in turn relieve the soil compaction and allow the roots to grow deeper, creating a healthier and thicker lawn. This is a great time to get over seeding done!
When should my yard be aerated?
Every lawn could benefit from being aerated at minimum once a year, however; twice a year is recommended.
Spring (March - May)
Fall (August - November)
What should I do after aerating?
Watering your lawn will help the break down process of the cores that remain on your lawn. You should never remove these cores as they play an important role in getting the nutrients back into the lawn.
Fertillizing, with no weed control, after your lawn is aerated is a great opportunity to have access to the root system.
Overseeding your lawn after it is aerated is another opportunity but make sure that you do this before the holes close up. The best time to do it is the same day or the following day.
One note to mention is that if you plan to fertilize and overseed then make sure that you are NOT using fertilizer that is a weed control combo, as this will prevent the seed from germinating properly.
It is always important to water properly.
When you have a string of hot days -> Turn your water up!!
Water at the right time of the day. 6 AM - 10 AM
Be on a schedule with your fertilizer.
Use the proper fertilizer for different times of the year.
Overseed when your lawn looks a little sparse.
