I have a customer who has a lawn (front lawn, the back is beautiful) that is very compacted, very poor, high-acid clay soil where the clover takes over the lawn, and the grass refuses to thicken, despite frequent fertilization, thatch removal, and overseeding. The lawn also dries up quickly when not given water (2-4 days) and goes dormant in the winter. The grass that is there is tall fescue, and fine fescue (creeping red). What is my first course of action to get this lawn back to full health? Aeration, slit seeding, or a complete re-start next spring?
