2. Round out the soil in your beds.
The shape of your beds can make a difference, too. Raised beds become more space-efficient by gently rounding the soil to form an arc. A rounded bed that is 5 feet wide across its base, for instance, could give you a 6-foot-wide arc above it. That foot might not seem like much, but multiply it by the length of your bed and you’ll see that it can make a big difference in total planting area.
In a 20-foot-long bed, for example, mounding the soil in the middle increases your total planting area from 100 to 120 square feet. That’s a 20% gain in planting space in a bed that takes up the same amount of ground space. Lettuce, spinach, and other greens are perfect crops for planting on the edges of a rounded bed.
