Next year I'm looking to expand my 50x60 garden to over an acre in size. I'm wondering what would work better initially to plow up the lawn and then maintain a garden year after year. Tillage discs or a plow and cultivator. I have an old fashioned push cultivator for weeding so a tractor driven cultivator I wouldn't use for weeding between the rows while the crops are small. Thanks for any advice/input.
