Looking for opinions. It's been our experience that most areas of lawns that need 'seeding' are those which experienced stress (probably why the original grass shelled out). Most often it involves compacted clay soil, and/or lack of proper watering, or mowing too low. What do you guys do regarding seeding compacted/stressed parts of lawns? 1) use a slit seeder? 2) use drill seeder? 3) making multiple passes with a hydrostatic core aerator before seeding? Just raising some eyebrows. What makes sense to you? Thanks.
