Some plants seem to do better, and are easier to handle when planted in beds rather than single rows. Try this with spinach, lettuce or other greens in beds 12 – 18″ across. Carrots are good in 6 – 8″ beds. Garlic and onions like to be almost touching when they are mature, so plant these in 4 or 5 closely spaced rows, like one wide row 4 garlics across. Don’t make beds so wide that you can’t comfortably reach across to work on them. Some grains and grasses will do better in beds because they hold each other up, where a single row stand will tip over too easily.
