Imagine harvesting nearly half a ton of tasty, beautiful, organically grown vegetables from a 15-by-20-foot plot, 100 pounds of tomatoes from just 100 square feet (a 4-by-25-foot bed), or 20 pounds of carrots from just 24 square feet.
Yields like these are easier to achieve than you may think. The secret to superproductive gardening is taking the time now to plan strategies that will work for your garden. Here are five high-yield strategies gleaned from gardeners who have learned to make the most of their garden space.
1. Build up your soil.
Expert gardeners agree that building up the soil is the single most important factor in pumping up yields. A deep, organically rich soil encourages the growth of healthy, extensive roots that are able to reach more nutrients and water. The result: extra-lush, extra-productive growth above ground.
2. Round out your beds.
The shape of your beds can make a difference, too. Raised beds are more space-efficient if the tops are gently rounded to form an arc, rather than flat.
In a 20-foot-long bed, for example, rounding the top increases your total planting area from 100 to 120 square feet. That’s a 20 percent 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.
3. Space smartly.
To get the maximum yields from each bed, pay attention to how you arrange your plants. Avoid planting in square patterns or rows. Instead, stagger the plants by planting in triangles. By doing so, you can fit 10 to 14 percent more plants in each bed.
Overly tight spacing can also stress plants, making them more susceptible to diseases and insect attack.
4. Grow up!
No matter how small your garden, you can grow more by going vertical. Grow space-hungry vining crops—such as tomatoes, pole beans, peas, squash, melons, cukes, and so on—straight up, supported by trellises, fences, cages, or stakes.
Growing vegetables vertically also saves time. Harvest and maintenance go faster because you can see exactly where the fruits are.
5. Mix it up.
Interplanting compatible crops saves space, too. Consider the classic Native American combination, the “three sisters”—corn, beans, and squash. Sturdy cornstalks support the pole beans, while squash grows freely on the ground below, shading out competing weeds. This combination works because the crops are compatible. Other compatible combinations include tomatoes, basil, and onions; leaf lettuce and peas or brassicas; carrots, onions, and radishes; and beets and celery.
