Hi folks, I need to have my lawn aeratored(sp?) and was going to do it by renting a core aerator machine from the local Home Depot or something similar. However, since I only have about 3,000 square feet of lawn, I was thinking of saving money and just using a steel rake or something to poke holes in the ground. Is this feasible? Do I really need to spend the money (e.g $60 for 4 hours of rental use) or can I get by and use something cheaper or a neighbor's tool? I'm seeing things like aerator sandals ($10), golf shoes, etc, mentioned in books and other forums. Any advice on what's best for my lawn size? I have St. Augustine grass and thatch problems and need to get some life into my lawn quick!
