A: Not anymore; however, we are always striving to be on the leading edge in our industry. With advancements in the lawn care market, we’re proud to offer a solution that works better and is more convenient for you, the innovative aeration technique called “N-ext Air-8.” This natural and biological approach to the old, out-of-date traditional aeration does more to create the same benefits. The best part is you no longer need to flag sprinkler heads, no more aeration plugs left behind all over your yard, no more healing time, and better results! N-ext Air-8 is safe for new sod, and includes aeration of hard-to-reach areas like the strip of grass between the sidewalk and street and sloped areas which are otherwise omitted with core aeration. Furthermore, with core aeration, loosening the soil is restricted to where the tines remove cores, which is only about 2-3 inches deep. N-ext Air-8 uses humates to loosen and create air exchange deep within the soil, which allows air, water, and nutrients to get down in the soil profile. A lawn with deeper roots is more drought tolerant, needs less frequent irrigation, and is thicker and healthier!
