What Is Square-FootGardening?

Square-foot gardening (SFG) is a type of raised-bed gardening—basically, a raised box divided into squares.With the square-foot gardening method, you plant in 4x4-foot blocks instead of traditional rows.Different crops are planted in different blocks according to their size; for example, 16 radishes in one square foot, or just one cabbage per square foot.A lattice is laid across the top to clearly separate each square foot.

This planting method was developed by American author and TV presenter Mel Bartholomew in the 1970s. It’s a simple way to create easy-to-manage gardens with raised beds that need a minimum of time spent maintaining them. SFG advocates claim it produces more, uses less soil and water, and takes much less time to maintain than a traditional garden.

Mel Bartholomew had just retired as an engineer and decided to take up gardening as a hobby. It was only natural that he would apply his analytical skills to the problems he encountered. In particular, he found the average gardener was spending hours weeding the big gaps between long rows of plants, creating unnecessary work for themselves. It soon became clear that getting rid of rows and using intensive deep beds could dramatically cut the amount of maintenance the garden required. Add a one-foot square grid on top, making it easy to space and rotatecrops.

What Size Is a Square-Foot GardenBed?

  • Typically, SFG beds are at least 4 feet by 4 feet, with a square foot lattice placed on top to visually separate the crops. That said, the beds can be 2x2 feet or 4x12 feet, but the most common is 4x4 feet. This allows plants to be situated more closelytogether.
  • To keep the planting simple, there are no plant spacings to remember. Instead, each square has either 1, 4, 9, or 16 plants in it, depending on the size of the plant—easy to position in each square by making a smaller grid in the soil with your fingers. As an exception to this, there are a few larger plants that span two squares. Climbing peas and beans are planted in two mini-rows of 4 persquare.

How Deep Isa Square-Foot GardenBed?

  • Beds should be deep—between 6 and 12 inches in depth in order to give plants plenty of rich nutrients, while still maintaining gooddrainage.

Other Square-Foot GardeningRules

  • A specific soil mix, which is water-retentive and nutrient-rich, is used to fill the beds. This provides a weed-free start as well as being water retentive and full of nutrients. The rich soil enables plants to be grown much more closely than normal, which in turn crowds outweeds.
  • Thin with Scissors: Instead of pulling up excess plants (which can disturb the root systems of the plants you want to grow), snip them off withscissors.
  • Never walk on the soil in the bed, as this will only compact the soil. Back in the 1970s, this was a revolutionaryidea!

Pros to Square-FootGardening

The “pros” for SFG are primarily ease and simplicity. SFG is a great method for new gardeners, people who have little time, the elderly or disabled (SFG gardens can be built at a raised height to make them more accessible), and children. Many schools have embraced the SFG method because it’s easy to install and maintain without becoming an additional burden for theteacher.

Cons to Square-FootGardening

  • Although many vegetables can be grown in SFG gardens, it struggles to accommodate larger plants (squash, melons, main-crop potatoes etc), perennials (globe artichokes, rhubarb), and fruit bushes/trees. Once new gardeners experience the success of SFG gardens, they often want to expand the range of crops they grow beyond the standard SFGcrops.
  • Originally, a soil mixture of peat moss, vermiculite, and compost (“Mel’s Mix”) was recommended in SFG.While this makes an excellent soil for vegetables, two of the three ingredients come from non-renewable sources. Peat takes thousands of years to develop and is a valuable natural sink for greenhouse gases. Vermiculite is mined and is therefore also a non-renewable resource with a significant carbon footprint. In common with many gardeners, we have moved toward using coconut coir instead of peat orvermiculite.
  • The specific soil mix and raised beds can be more expensive to set up than alternative methods, even though SFG is easier tomaintain.

None of these reasons prevent SFG from being a useful part of a garden, though!You can use 100% recycled compost in the beds instead of Mel’s Mix, gradually build up the number of SFG beds and combine it with areas of your garden which are set aside for fruit trees and larger crops. Many of the SFG techniques that were revolutionary in the 1980s are now commonly used for vegetable gardening:deep raised beds, not compacting soil, removable covers and plant supports,etc.

Does Square-Foot GardeningWork?

Yes, square-foot gardening works for those who have limited space because it allows plants to be situated more closely together. Also, we have definitely found that there is less weeding. If you don’t have a lot of time available to weed, water, and maintain your vegetable garden, then square-foot gardening could be the answer.Finally, SFG has the benefits of all raised beds in that the soil warms more quickly for earlier planting andharvest.

However, there are limitations in what you can grow.As said above, plants that need more space such as corn, potatoes, watermelon, and pumpkins do not fare as well inboxes.

Square-foot gardening was revolutionary when it was first invented and it’s still a great system for people who are starting out, have limited space, or want a highly organized method to follow. However, you don’t need to follow SFG to benefit from gardening with raised beds and good organization. There’s a great quote: “If the only tool you have is a hammer, you tend to see every problem as anail.”

SFG works really well for many situations, but it doesn’t fit everything. The success it brings can often lead people on to discovering the delights of fruit trees, using barrels to grow huge crops of potatoes, or managing a greenhouse full of high-value crops. It’s a great stepping-stone to the world of growing your own food and that’s whyit’s still going strong 35 yearslater!

3. Large-Scale SFGGarden

“Raised bed gardens with an emphasis on companion planting with the new tool. Soil is so-so but manure and compost and lime helped and will add more this year. Wondering about the problem of rotating crops next year but I hope the benefit of attracting beneficials will override that. I’ve got a three sisters garden (corn, beans and squash) and onions planted everywhere to help ward off pests. There are all the flowers that attract beneficials that I could fit in. I think it will take a lot of time to plant - but I am looking forward to it! Using the plant list now to organize my seed starts - Onions and leeks and shallots are up and waving! I have notes on seed starting on my plant list page. NOTE: Since I wrote this I have made changes due to the groundhog, primarily putting all the onion family and many herbs/flowers where he came in lastyear.”

How do you grow a lot of vegetables in a small space? ›

You can grow two or more vegetables in one area by planting slower-maturing and faster-maturing crops together. The quick-to-mature vegetables will be ready for harvest before the two crops begin to crowd each other. Once the fast crop is picked, the slower crop will have more room to grow to maturity.

What is one of the biggest disadvantages to square-foot gardening? ›

Some of these detriments, according to Bartholomew, are the amount of space single-row production requires, the large amount of soil amendments needed, and the amount of seed used to plant the rows.

What is one strategy for getting more produce out of a small garden? ›

Another way to support higher yields in small garden spaces is to avoid planting the same family of vegetables in the same spot every year. Research shows that rotating crops so that one plant family occupies a given location only every three or four years has positive effects on yields.

How do you layout a small vegetable garden? ›
