Most of my vegetables are grown in this way, the soil is covered with mulch, in the picture we can see tomatoes plants, they grow without plowing, cultivation, once a week irrigation, (or no irrigation needed if there is raining at least once a week). Only in springtime, I replant the tomatoes plants in the soil, loosening only a small area where roots will grow, then I cover the soil with straw. There are more tricks and tips that you can learn from me here at my place, where I can also host, I organize every month a workshop where people can learn in practice.
