It's a fact, aeration is one of the best things you can do for your lawn.
Compacted soil and heavy thatch are the two biggest obstacles to a beautiful lawn. They tend to suffocate grass plants by preventing air, water, and nutrients from reaching the root zone. This means your lawn looks less than satisfactory in spite of adequate fertilization, water, and tender loving care! Aeration opens up the thatch and helps relieve compaction. It should be a regular part of your annual lawn maintenance.
Aeration is accomplished through the use of a machine equiped with cylinder-like tines designed to penetrate and shatter the soil. Cores of thatch, soil, and grass are actually pulled out of the ground during the process. The plunging action of the tines opens the soil, allows the grass plants to breathe, permits better utilization of fertilizer, air, and water and promotoes a deeper, healthier root system.
And good roots are what growing a good lawn is all about!
