Want fresh vegetables this summer, but don’t have a lot of time? Don’t like the hours in the hot sun weeding and caring for plants? Mel Bartholomew, backyard gardener, engineer, and efficiency expert, invented the Square Foot Gardening method which might interest you. Here in Warrenton, we have certified Square Foot Gardening experts James and Nichole Brown of Nature’s Wellspring, a company dedicated to providing seeds, produce, custom grown plants, and homeopathy products for the community.
Square Foot Gardening is the practice of creating small, orderly, and highly productive gardens by dividing the growing area into small sections, typically in 12” squares. Seeds or seedlings of each kind of vegetable are planted in one or more of the one-foot squares, at a density based on plant size. The square foot gardening method is estimated to cost 50 percent less, use 20 percent less space, use 10 percent less water, and require only 2 percent of the work compared to single row gardening. Additional benefits are that the density of the crops prevents weed growth, and no digging, tilling, or heavy tools are necessary.
Steps to Square Foot Gardening:
- Select the location of your garden. Is there enough sunlight (at least 6-8 hours per day)? Is the soil well drained? Is it in a spot that has easy access for daily maintenance and harvesting? Is it close enough to a water supply?
- Choose a size for your garden, in proportion to how much space you have, how much you want to plant, how much you can realistically take care of. Typical Square Foot Garden sizes might be 4’ x 4’ or 4’ x 8’
- Build your bed. Use untreated cedar, pine, or fir, brick, cement blocks, or other materials to form your border
- Fill with soil. First, get your soil tested to find out what nutrients are needed for preparing your soil for growing. The Fauquier Extension office/Master Gardening program can help package your soil samples that are sent to Virginia Tech for analysis. Square Foot Gardener experts recommend “Mel’s Mix,” consisting of ⅓ coarse grade Vermiculite, ⅓ Sphagnum Peat Moss or Coconut Coir, and ⅓ Blended Organic Compost.
- Add a grid. Divide your bed into 12” squares using pieces from Venetian blinds or wood lath. The grid is one of the most important features of a SFG, since it helps you see clearly and properly space your seeds or plants. If you are starting from seed, get a Seeding Square which will help you achieve the most efficient layout.
- Select your seeds or plants, and start growing! The last frost date for our area tends to be in late April to early May. We use Mother’s Day as the safe date for planting seedlings outside.Ready to go? See the chart to plan how to space your seedlings or seeds.

Raised beds work very well for SFG and have many benefits. They look very nice in the yard, and the height of the bed can be tailored to the needs of the gardener, thus allowing those with physical limitations to still enjoy and be successful at gardening. Raised beds also create a barrier that aids in weed control and small animal prevention in your garden. The pitfall of the raised bed is that it will initially require more soil prep and amendments than the traditional method.
Another thing that is important for beginners to understand is companion planting because some plants support each other and others sabotage each other. The SFG method helps guide you on which plants work well together. Here are some recommendations from Nature’s Wellspring:
