Fertile soil that retains nutrients and water is one of the keys to success with intensive planting, which is a fancy way of saying planting a lot in a little area. America’s intensive-growing tradition has two fathers: John Jeavons and Mel Bartholomew. In his classic 1974 book, How to Grow More Vegetables Than You Ever Thought Possible on Less Land Than You Can Imagine, Jeavons introduced Americans to French intensive-gardening techniques, notably deep soil preparation through double-dug beds and intensive crop-planting patterns. Seven years later, Bartholomew offered a new way to think about these patterns in a classic book of his own
Keyhole gardens are designed to maximize space by eliminating the need for walkways as found in traditional row gardening or with raised beds. The design is also intended to be draught-resistant and deliver nutrients via compost throughout the entire growing season. Keyhole gardens are a raised style bed that take the rough shape of a circle with a keyhole shaped path allowing access to the entire garden. In the center of the circle is a vertical tunnel that houses many layers of compost. As the compost breaks down it delivers nutrients and moisture directly to the bed. Certainly an efficient way to grow, keyhole gardens can be constructed with many different materials as a quick Google search of the term will confirm. If you have space for a circle roughly 8 - 10 feet in diameter you can use whatever appropriate materials that are easily accessible corrugated siding, cedar posts, landscaping rock, bricks or any combination thereof. We have a page dedicated to keyhole gardens for more details.
