Clay Soil Lawn: Aerate, Don't Just Topdress

Central NJ, 10 years. Hard spots, overly wet after rain, few earthworms. Clay confirmed. Coffee grounds? Earthworms? Compost?

Clay Isn't the Killer—Patchy Wetness Is

• If whole lawn wet → aerate/break up.
• If patches wet → fill depressions gradually.

Roots Need Depth

Aeration creates pores for roots → water infiltrates → clay improves slowly. Coffee grounds, worms, compost help but volume needed is huge.

Focus on drainage + root depth. Time fixes clay.
