Rent the heaviest aerator you can find, pull cores as deep as you can. I'd go two passes, if you can approximate a 2.5 x 2.5" pattern (most aerators produce a 5x5 for one pass) that's awesome. The sand will fill in the holes and help provide a semi-permanent channel for all the goods to reach the root zone. 4.Web
