So this will be my second year having a vegetable garden. Last year I had a lot of trouble with weeds and someone told me that I should have tilled the land, waited a week, tilled again, wait another week, till once more and then it would be ready to plant. He said that this would get rid of any weeds in the area, but I've read online that a lot of people say too much tilling is bad for the soil. I do have compost that I will be adding but I don't want to destroy that soil that is already there. Any advice?
