It's time to throw that tiller away. Yes, you read correctly. No need for that gas-guzzling, energy sucking contraption any more. But those with a love of power tools need not worry, because it is time to construct some raised beds to not only save some time and energy, but it could save your knees too.

Raised beds may be simple or elaborate, according to the gardener's preference. A raised bed is typically a box filled with dirt, allowing proper drainage and aeration to the plants growing within. One to two feet is a standard depth, with widths and lengths dictated by the gardener. It is helpful to make the raised bed narrow enough to reach in without stepping on the soil, but wide enough to allow enough room for proper root growth.

When cultivating in raised beds, it is not necessary to till the soil. Crop rotation is a far more effective method for keeping the soil healthy, as well as adding compost and other organic materials. A thick layer of mulch keeps weeds out and plants hydrated. As an added bonus for those who are "green" minded, studies have shown that carbon dioxide (CO2), a major greenhouse gas, is retained more effectively in beds in which the crops are rotated than in those which are tilled. This helps keep the gases trapped in the soil instead of the atmosphere. And if a tiller isn't used, not only are fuel and labor costs saved, but fewer emissions are allowed into the environment.

For those with weak backs and knees, raised beds are a joy. The beds can be made to be accessible for the wheelchair-bound and those who just can't bend or kneel as well as before. This is great news for homeowners and those in nursing homes who cannot have a traditional garden. The level of the raised beds makes it easier to pull any of those rogue weeds that may have sprouted, or easily fertilize plants without excessive bending or kneeling.

Raised beds are a joy for children, because the plants are at eye-level, encouraging interaction in the planting process. Children love fresh grape tomatoes off the vine, and these plants are vigorous growers in a raised bed with an adequate season. Raised gardens offer children opportunities to see plant and insect life in an amazing way. Why not have raised beds especially for the kids?

Everyone loves a beautiful lawn and summer garden, but gardening can be irksome when the tiller won't start and it's time to bend down on the old knees to pull some weeds. Virtually any plant that can be grown traditionally can also be grown in a raised bed, often with better results. Raised-bed gardens may be the answer to may gardeners' prayers.
