Aerating the day after a rain shower or watering your lawn the day before is advised. Most aeration machines cover only a small percentage of soil surface per pass, so make multiple passes over the most compacted areas.

Step 2: Mow your lawn. Give your grass a trim with your lawnmower, and aim to cut it to the recommended height for your specific type of grass. Without mowing first, longer grass can interfere with the aeration process, making it less efficient in addressing soil compaction and limiting the benefits to your lawn.
