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.
Always look for opportunities for your garden to make the most of the space you have. Minimal horizontal gardening space just means you will have to build up instead of out. Remember not to let your vertical garden get too tall so that you would not forget about tending to the plants on top. Build raised garden beds. Stack pottery/Add Tiers and Layers. Create a stacked herb or succulent garden to maximize planting space on the corner of a deck or patio. Grow vines and climbing plants on trellises, fences, or walls
