When lawns start to look unhealthy, aeration might be the best solution. When a lawn is aerated, small cores of dirt are removed form the ground, giving the lawn more oxygen, water and room to grow.
For those of you who want to consider lawn aeration, you have a couple of options. You can either hire a lawn care service or you can consider doing it yourself. If you are planning on doing it yourself, there are several factors that you should consider.
According to Shannon Dauphin from All About Lawns, the best times to aerate your lawn are considered spring and fall. She suggests that if you have a warm season grass in your lawn, you should aerate in the spring because it can recover more quickly. Cool season lawns grow more rapidly in the fall so it is better to aerate them during that time.
