Yes. Aeration can make a big difference on the health of your lawn. Aerating creates holes in the soil and removes plugs which has several benefits. First, it reduces compaction in the soil making it easier for turf roots to spread and thrive. Second, it allows water and oxygen to enter into the ground easier and at a higher rate. If your lawn is compacted the rainwater can easily have the tendency to run off the lawn before it has time to absorb. With the aerated lawn the water can absorb easily into the small holes and infiltrate the root system of your grass.
