Whatever genius came up with raised bed gardening had to suffer from back problems. The simple fact that raised beds mean less bending over (and fewer resulting backaches) is reason enough for using this gardening method. In addition, raised beds enable better control and management of everything from soil enhancements to watering schemes to weed control, and it lends itself to gardening in small spaces. Here are three factors to consider when you’re choosing a raised bed garden kit.

One great advantage to a raised bed system is its mobility, to the point where some kits come with wheels. If your garden plans call for moving your beds from one year to the next, or even seasonally (to follow the sun), look for a self-contained bed that’s easy to move.

Some raised bed kits are simply open-bottomed enclosures designed to hold the soil or growing medium and raise its level higher than the ground. Others are fully self-contained. If mobility is less a factor, there are a number of open-bottomed enclosure styles available.

The materials used in your raised bed kit will determine its longevity. Prolonged exposure to damp soil promotes rot, so wood-based raised garden systems should be made of rot-resistant wood like cedar (not treated lumber than can leach harmful chemicals). Prolonged exposure to sunlight quickly makes plastic brittle, so composite materials used for raised beds should be UV-resistant.
