Square foot gardening is the practice of dividing the growing area into small square sections.The aim is to assist the planning and creating of a small but intensively planted vegetable garden. It results in a simple and orderly gardening system, from which it draws much of its appeal. Mel Bartholomew coined the term "square foot gardening" in his 1981 book of the same name.
The phrase "square foot gardening" was popularized by Mel Bartholomew in a 1981 Rodale, Inc. book [1] and subsequent PBS television series. [2] Bartholomew, a retired engineer, devised the system.
The square foot gardening method recommends using an open-bottom raised bed, 4 by 4 feet (1.2 m × 1.2 m) square. The square beds are then divided into a grid of sixteen one-foot squares. Each square is planted with a different crop, and based on the plant's mature size either 1, 4, 9 or 16 plants are placed per square. Although beds can be longer than four feet, it is recommended for the width of the bed to be no more than four feet because an adult arm can usually reach 2 feet—the distance from the edge to the center of the bed.
Once a "square foot" is harvested, a different crop can be planted. To encourage a variety of different crops in succession, and to discourage pests, each square is used for a different kind of plant (crop rotation) within the growing season. The number of plants per square depends on an individual plant's size. For example, a single tomato plant takes a full square, as might large herbs such as oregano or basil, while lettuce plants would be planted 4 per square, and up to 16 per square of plants such as radish or carrots. Tall-growing crops are planted or trellised on the north side of the bed (in the Northern Hemisphere) to avoid shading shorter plants.
One advantage of densely planted crops is that they can form a living mulch and can also prevent weeds from establishing or even germinating. A variety of crops in a small space also prevents plant diseases from spreading easily. [3]
Since the beds are typically small, making covers or cages to protect plants from pests, cold, wind or too much sun is more practical than with larger gardens. To extend the growing season of a square foot garden, a cold frame may be built around it, and by facing the frame towards the equator, the square foot garden captures more light and heat during colder months of the year.
No specific soil is required although it is recommended to add compost to garden soil. In 2006, Bartholemew began advocating the use of "Mel's Mix", which he described as 1/3 peat moss or coconut coir, 1/3 vermiculite, and 1/3 compost which he claimed yields good results even at only 6 inches (15 cm) depth.
Gardening is the practice of growing and cultivating plants as part of horticulture. In gardens, ornamental plants are often grown for their flowers, foliage, or overall appearance; useful plants, such as root vegetables, leaf vegetables, fruits, and herbs, are grown for consumption, for use as dyes, or for medicinal or cosmetic use.
Raised-bed gardening is a form of gardening in which the soil is raised above ground level and usually enclosed in some way. Raised bed structures can be made of wood, rock, concrete or other materials, and can be of any size or shape. The soil is usually enriched with compost.
Companion planting in gardening and agriculture is the planting of different crops in proximity for any of a number of different reasons, including weed suppression, pest control, pollination, providing habitat for beneficial insects, maximizing use of space, and to otherwise increase crop productivity. Companion planting is a form of polyculture.
Spent mushroom compost is the residual compost waste generated by the mushroom production industry.
The following outline is provided as an overview of and topical guide to organic gardening and farming:
In agriculture, succession planting refers to several planting methods that increase crop availability during a growing season by making efficient use of space and timing.
Season extension in agriculture is any method that allows a crop to be grown beyond its normal outdoor growing season and harvesting time frame, or the extra time thus achieved. To extend the growing season into the colder months, one can use unheated techniques such as floating row covers, low tunnels, caterpillar tunnels, or hoophouses. However, even if colder temperatures are mitigated, most crops will stop growing when the days become shorter than 10 hours, and resume after winter as the daylight increases above 10 hours. A hothouse — a greenhouse which is heated and illuminated — creates an environment where plants are fooled into thinking it is their normal growing season. Though this is a form of season extension for the grower, it is not the usual meaning of the term.
Eliot Coleman is an American farmer, author, agricultural researcher and educator, and proponent of organic farming. He wrote The New Organic Grower. He served for two years as Executive Director of the International Federation of Organic Agriculture Movements (IFOAM), and was an advisor to the U.S. Department of Agriculture during its 1979–80 study, Report and Recommendations on Organic Farming, a document that formed the basis for today's legislated National Organic Program (2002) in the U.S.
Plugs in horticulture are small-sized seedlings grown in seed trays filled with potting soil. This type of plug is used for commercially raising vegetables and bedding plants. Similarly plugs may also refer to small sections of lawn grass sod. After being planted, lawn grass may somewhat spread over an adjacent area.
A market garden is the relatively small-scale production of fruits, vegetables and flowers as cash crops, frequently sold directly to consumers and restaurants. The diversity of crops grown on a small area of land, typically from under 0.40 hectares to some hectares, or sometimes in greenhouses, distinguishes it from other types of farming. A market garden is sometimes called a truck farm in the USA.
Biointensive agriculture is an organic agricultural system that focuses on achieving maximum yields from a minimum area of land, while simultaneously increasing biodiversity and sustaining the soil fertility. The goal of the method is long term sustainability on a closed system basis. It is particularly effective for backyard gardeners and smallholder farmers in developing countries, and also has been used successfully on small-scale commercial farms.
Organic horticulture is the science and art of growing fruits, vegetables, flowers, or ornamental plants by following the essential principles of organic agriculture in soil building and conservation, pest management, and heirloom variety preservation.
Blood meal is a dry, inert powder made from blood, used as a high-nitrogen organic fertilizer and a high protein animal feed. N = 13.25%, P = 1.0%, K = 0.6%. It is one of the highest non-synthetic sources of nitrogen. It usually comes from cattle or hogs as a slaughterhouse by-product.

A keyhole garden is a two-meter-wide circular raised garden with a keyhole-shaped indentation on one side. The indentation allows gardeners to add uncooked vegetable scraps, greywater, and manure into a composting basket that sits in the center of the bed. In this way, composting materials can be added to the basket throughout the growing season to provide nutrients for the plants. The upper layer of soil is hilled up against the center basket, so the soil slopes gently down from the center to the sides. Most keyhole gardens rise about one meter above the ground and have walls made of stone. The stone wall not only gives the garden its form, but helps trap moisture within the bed. Keyhole gardens originated in Lesotho and are well adapted to dry arid lands and deserts. In Africa, they are positioned close to the kitchen and used to raise leafy greens such as lettuce, kale, and spinach; herbs; and root crops such as onions, garlic, carrots, and beets. Keyhole gardens are ideal for intensive planting, a technique in which plants are placed close together to maximize production. Plants with wide-reaching root systems, such as tomatoes and zucchini, may not perform well in a keyhole garden.
French intensive gardening also known as raised bed, wide bed, or French market gardening is a method of gardening in which plants are grown within a smaller space and with higher yields than other traditional gardening methods. The main principles for success are often listed as soil improvement, raised beds, close spacing, companion planting, succession planting and crop rotation. Originating in France, the practice is very popular among urban gardeners and small for profit farming operations.
There are many ways to garden in restricted spaces. Often a small or limited space is an issue in growing and cultivating plants. Restricted space gardens can be located on small lawns, balconies, patios, porches, rooftops, inside the home, or in any other available place. Gardening in small places can be applied to edible or floral plants. Growing food has many benefits including saving money; healthier, fresher, and better tasting food; knowledge of pesticide and fertilizer exposure. Gardening is a good form of exercise and has been proven to be therapeutic.
Hügelkultur, literally mound bed or mound culture, is a horticultural technique where a mound constructed from decaying wood debris and other compostable biomass plant materials is later planted as a raised bed. Adopted by permaculture advocates, the technique helps to improve soil fertility, water retention, and soil warming, thus benefitting plants grown on or near such mounds.
Gardening Naturally is a TV show series hosted by Barbara Damrosch and Eliot Coleman. It was created from 1993 to 1994 and ran until about 2003. It first aired on TLC and later reruns were shown on Discovery Home and Leisure.
Mel Bartholomew was an American gardener, engineer, inventor, businessman, television presenter, and writer. He is known for originating the method of square foot gardening.
