I do raised bed gardening. There is no work to it. Since it is raised, it gets very little weeds- I spend about 1/2 hour total all summer weeding, and I don't even have to bend down to weed. Any weeds are from seeds blown it so they might be 1/2 inch tall when I have discovered them and have not developed a root system.
I order 18 2x4's from the lumber yard, and ask them to cut 6 of those in half. There is usually no charge for this service. I also get a pound or 2 of nails. I pound it together- it takes about an afternoon to build. Fill the bottom with lawn rakings leaves, branches, or whatever you like. Fill the top 8-10 inches with dirt, and plant. You do not need to make rows, since you will not be tilling or hoeing. Broadcast your seeds. Enjoy. No space is wasted on rows, so practically every inch is used. In the winter, the frost will heave it, tilling it. The veggies grow prolifically. This is a very good way to garden for someone elderly or disabled, since there is no work to it . My gardens are 4' by 8'. The first one I built was accessable from both sides, but I have since realized I don't need to do that. I can reach across from the front, but someone with reaching problems might have to have it accessable from both sides. I have 3, now. One has green beans, yellow beans and beets. The next one has carrots, spinach, radishes, and more beets. The last one has squash, that I grow vertically on trellisses to save space.
