Raised-bed gardening is an option for yards with limited space or poor soil. A raised-bed garden also works well for gardeners with limited mobility or who have problems bending over and kneeling.
A variety of materials can be used to make a raised bed. The beds can be of any shape and designed to fit the space available for gardening. This design is for a structure that is 4 feet wide by 8 feet long and 1 foot high. To use the raised bed in a patio or deck, place the raised-bed structure on a sturdy, 4- foot by 8-foot table.
Lay two 8-foot boards on the ground, about 4 feet apart.
Place one 4-foot by 2-inch board at each end, between the 8-foot-long boards.
Use the power drill and drill three holes on each end on the side--about 1 inch from the top--of the 4- foot-long boards. Drill one hole near each end and one in the middle between the two end holes.
Using three screws for each end, attach the 4-foot board to the 8-foot board.
Using one screw for each side, attach a 1-foot by 4-inch board, diagonally at each corner. This creates a brace for your rectangle. Your structure is ready for soil.
Lay three bags of soil side-by-side inside your structure.
Use a utility knife to cut a large rectangle on the top of each bag. Leave the sides and about 1 inch of the top--it will resemble a window or picture frame. Another option is to pour soil directly into the structure.
Mix a small amount of compost or fertilizer with the soil. Skip this step if the bag of soil has already been fertilized--it should be labeled on the outside of the bag.
Using your hand-gardening tools, plant your vegetable or flower seeds or seedlings. Follow package instructions, giving ample room for each plant to reach maturity.
Thoroughly water your garden. Remember to water daily.
