"A raised garden bed extends the planting season, offers versatility to the gardener and helps protect your knees by bringing plants up from a level position on the ground.
Also known as garden boxes, raised garden beds are ideal for growing flowers and vegetables virtually anywhere.

rewards you get from them is critical. Luckily, it’s fairly simple to do

to maximze its growing portential." http://www.raisedgardenbedshowto.com/
