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.
If you must have a giant beefsteak tomato or a row of sweet corn, the space for growing other vegetables in your small vegetable garden will be limited. But even then, you can choose varieties that are bred to grow in small spaces. Anything with the words patio, pixie, tiny, baby or dwarf in their name is a good bet. Just because a plant is bred to be small does not mean the fruits will be small or the yield will be less.

They are all great ways to made a big gardening impact – even on the most limited high rise balcony! Here are some considerations and expert techniques when planning your small garden.
