Here’s how to get the most out of your garden.

Check out these 7 tips for a high-yield vegetable gardenImagine 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 seven 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.

The fastest way to get that deep layer of fertile soil is to make raised beds. Raised beds yield up to four times more than the same amount of space planted in rows. That’s due not only to their loose, fertile soil but also to efficient spacing—by using less space for paths, you have more room to grow plants.

Raised beds save you time, too. One researcher tracked the time it took to plant and maintain a 30-by-30-foot garden planted in beds, and found that he needed to spend just 27 hours in the garden from mid-May to mid-October. Yet he was able to harvest 1,900 pounds of fresh vegetables—that’s a year’s supply of food for three people from about 3 total days of work!

How do raised beds save so much time? Plants grow close enough together to shade out competing weeds, so you spend less time weeding. The close spacing also makes watering and harvesting more efficient.

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. A rounded bed that is 5 feet wide across its base, for instance, will give you a 6-foot-wide arc above it—creating a planting surface that’s a foot wider than that of a flat bed. 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, 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.
