Core Aeration and overseeding. I use the best aerator available (Billygoat 2501 Reciprocating aerator). I attached a Gandy seed box to the aerator, so seed drops as the lawn is aerated, and only 1 trip over the lawn is needed to core aerate and overseed. I can supply seed, or use seed that you provide, to save a little money. If you want to see the aerator in action, search YouTube, Billygoat 2501 aerator. There are some hills that are too steep, so I like to do a site visit, to determine. Click on reply to ad to get in touch, I reply ASAP to all replies.
