so I want to aerate my lawn now that the weather is getting warmer, however, i'm not sure how to proceed with it. i've ruled out renting a power aerator from Home Depot because 1) they're heavy and require 2 people to load into a truck and 2) I don't have a truck nor do I want to rent one. so, this leaves me with the manual aerator option. does anyone know where I can buy a manual core aerator? does Home Depot sell them or do I have to go to a garden store? I'm not sure what my options are for manual core aerators so if anyone has experience with them feel free to share your thoughts
