The short answer is you should aerate anytime as long as you can you can pull 2-3 inches plug or better.
However, when is the very best time, well there are mainly two seasons, the spring and the fall. There are some great reasons behind the aeration in these two seasons.
Spring is a great time to aerate because I always recommend that you should also throw down some grass seed right after the aeration. Not that the grass goes in the holes but it’s just made you know that the lawn is a little bit rougher things and it’s a great time to throw down some grass seed.
The other reason that you could aerate in the spring if you have a thatch problem. Thatch is the layer of kind of organic material a lot of its mostly dead grass, leaves, and other things that resides just above the soil line.
Now, there is a common misconception:
Thatch is always a bad thing. That’s not right always. Thatch is good and thatch is bad as well. Too much thatch though can cause shallow rooting and cause all kinds of problems in the lawn.
So, aeration is a good way to control thatch. Aeration controls thatch without completely eliminating it.
Now, another very best time of aerating lawn is fall. The reason you should aerate in the fall because that’s when the lawn is doing most of its root zone growth. In fall, they spread their roots in preparation for winter. So, aeration is going to loosen hard compacted soil and basically allow the soil to relax and more root growth.
Most people like to aerate lawn in the in fall because that is way better than aerating in spring. Watch the video below to get awesome 6 tips about fall lawn care.
Grass Types when aerating lawn
Grass-types is another important factor that affects the timing of lawn aeration. There are mainly two kinds of grass that you mainly have.
If your lawn is a cool season grass like bluegrass, the best times to aerate are when the temperatures are cooler and weeds less active. In the fall, at least four weeks before the first hard frost or in the spring.
If you have one season variety like Bermuda grass, the best time to aerate is mid-spring to early summer when the grass is actively growing but it gets too hot and dry.
