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.

I have my strawberries in raised beds. Going to put my vegetables in next year in raised beds, too. I really like it. It is a lot easier to clean.
