A circular vegetable garden can be a visually striking alternative to the traditional rectangular garden plot. While it doesn't necessarily use less land, a circular plot can make it easier to reach your vegetables and care for them.
Choose six to eight different plants, all bush varieties if there is a choice. Green beans, peppers, carrots, radish, broccoli and peas are all suitable choices. One vining plant, like tomato or cucumber, can be placed in the middle of your circle.
Measure your circle to include six to eight pie-shaped wedges no more than 4 feet wide at the base. You will have walkways between each wedge and a circular planting area in the center of the garden.
Building the Beds
Create raised beds in your garden with bricks, cinder blocks or railroad ties. Fill the areas with topsoil mixed with compost and rotted manure. Make sure that the soil mixture is about 18 inches deep.
When the growing season has passed, pull all dead plants and cover all planting surfaces with a 6-inch layer of dead leaves or straw. In the spring this mulch can be turned into the soil to compost for additional nutrients.
The circular design is convenient because your vegetables are easier to reach and water, and there is less weeding in a raised-bed garden. The circular design also adds a decorative element to your landscaping.
