Fixing Builder’s Bad Lawn Prep in Utah: Compost, Aerate, Repeat

Builder brought one load of topsoil for 10,000+ sq ft in Logan, UT—hot, dry summers, clay underneath. Kentucky bluegrass struggles. Building soil takes years. Don’t quit.

Best amendment: thermophilic compost (10 cy for 10k sq ft). Aerate, apply ⅜ inch compost over seed. No fertilizer/lime needed. Compost adds biology, nutrients, builds A-horizon. Do every fall until lawn performs. Sand later for leveling.

Find a pro supplier with analysis (1-3-1 to 2-5-2 N-P-K + micros). It’s an elixir for bluegrass.
