Hollywood Squares

The square foot gardening method consists of raised beds usually measuring 4 feet by 4 feet that are divided into grids of 16 boxes measuring one square foot each. A larger square foot garden can be achieved by placing an additional 4 foot by 4-foot beds about 2 feet apart.

Sizing things up

One of the great benefits of square foot gardening is how easily adaptable it is to your available space. You can start off slow with a 4 foot by 4-foot garden and add further blocks as time and space permits.

Just because you’re thinking inside the box doesn’t mean the box has to be square. If you have a small or odd-shaped yard, there’s no reason a square foot garden can’t be long and rectangular or any other shape that can be broken down into square foot boxes.

Crop rotation

Square foot garden boxes vs. raised beds

Square foot gardening and raised bed gardening are two of the most popular gardening trends around and are often mistaken for one another. The major difference between square foot garden boxes and raised beds is that square foot garden boxes are built on a grid.

Raised beds offer easier access and a convenient means of using well-drained and fertile soil, but raised beds are otherwise planted much like traditional open soil gardens. Square foot garden boxes are broken down into consecutive areas of one square foot each. This grid is what gives square foot gardens their unique checkerboard appearance. A square foot garden grid makes for easier crop rotation and supplies gardeners with all the benefits of companion planting.

Size and materials

The commonest size for square foot garden boxes is 4 foot by 4 foot, though small space gardeners may prefer boxes that are 3 foot by 3 foot or 2 foot by 2 foot. Square foot garden boxes should be about six to eight inches deep. Deep bed gardeners may build up to heights of 12 or 16 inches.

Square foot garden boxes can be built from many different materials. Wood Garden is the most popular choice. Most gardening sources caution against used treated lumber when building raised garden beds because treated lumber can become toxic to plants. Untreated wood is an acceptable choice. Some gardeners enjoy using traditional rustic furniture woods such as pine and cedar for their square foot garden boxes. Bricks, stone, and cinder blocks are alternative materials used in garden bed construction.

Another building material that is gaining in popularity is rubber. Square foot garden boxes made from rubber are cheaper to build than wooden garden boxes and last a lot longer.

Grids and soil

Old Venetian blinds are a simple visual aid, as is string wound around small wooden spikes. Long, thin pieces of wood are another option. A 4 foot by 4-foot garden box should feature 16 smaller boxes.

Of course, you’re going to need soil before you construct your grid. Having a fertile soil mix is critical for a successful square foot garden box. Mel Bartholomew, the creator of square foot gardening, recommends a mix of 1/3 compost, 1/3 peat moss, and 1/3 coarse vermiculite.

Garden box etceteras

If you’re using more than one 4 foot by 4-foot garden box, provide just enough space for you to work comfortably between them. If your gardening space is unconventional or small, experiment with L-shaped boxes or other designs.

If you decided to use treated lumber to build your square foot garden box, line it with heavy-duty plastic as a precaution before adding soil.

Go easy on seeds, water, and fertilizer. Square foot garden boxes make efficient use of the resources you provide, saving you time and money.

To determine how many plants are appropriate per square foot, look at the recommended spacing. If a plant requires 12 inches of space, then assign a single box in your grid to that plant. If a plant requires four inches of space, you’ll be able to fit nine plants in one square, i.e. three rows of three.
