By September the ground under a lawn has been walked on, parked beside and baked all summer, and compacted soil does not forgive that on its own. Lawnster Lawn Care & Aeration answers in Columbus with core aeration, pulling plugs and leaving them scattered over the turf like dark commas until the first good rain takes them back down. Mowing and trimming keep the top of a lawn honest; aeration is the part nobody watches, and it's the part that decides how April will go. There is something quietly hopeful about opening the soil up just as the trees begin to turn. The work gets done in autumn and paid back in green.
