I have a question that will seem basic to a lot of people, but it's hardly ever discussed in articles I've read on gardening. and that is: how do you go about putting pathways in your vegetable garden so you can move around to weed, harvest, etc.? I've tilled up a 20X40 foot area and the soil is all light and fluffy now. If I step in to start planting, I'm going to sink in, right? Do I have to lay down planks or something to walk around? That seems like heavy work, awkward and impractical. What do people usually do?
