In a little over a month I will start planting my garden (between March 15-30). Last year I had a severe problem with weeds taking over the garden. I planted quite a bit of sweet corn; that did well in spite of the weeds. I will be planting the garden where I currently have my green field. Where I am planting the sweet corn should I kill the green field with an herbicide and till under or kill the green field and plant the seed without tilling the field? Or would you till the ground wait for the weeds to come up and than spray with an herbicide and than plant the sweet corn? I just want to know the best way to plant sweet corn. I planted watermelon and cantaloupes last year and they started out great but the weeds overcame the garden and did not get any watermelon. This year I plan on using a fabric or poly plastic with soaker hoses running under the ground cover to control the weeds. I think that will solve that problem. It will be a little more labor intensive to use the ground cover but I think the effort will pay off in the end. Do you all have any thoughts or experience on using ground cover (fabric/poly) in a vegetable garden?
