Let’s summarize what you’ve learned about aerating your St. Augustine grass.

The best time to aerate is when the grass grows in late spring and early fall. This allows it to recover fast from aeration and grow strongly.

You have two methods of aeration: core aeration and spike aeration. For St. Augustine grass, core aeration is usually better because it removes soil plugs instead of making holes. This method helps the soil absorb more water, reduces soil hardness, and encourages roots to grow deeper.

Aeration can have drawbacks too. Doing it too much or at the wrong time can weaken the grass and expose it to pests or diseases. So, you need to keep an eye on the weather and the health of your lawn.

Aerating your lawn has clear benefits like better growth and less thatch. It gives water, nutrients, and air a direct path to the roots, leading to a thicker lawn.

But remember, no single method can create a perfect lawn all year. Regular aeration, however, can greatly boost your lawn’s health over time.
