What is a keyhole garden?
A keyhole garden is a unique and highly efficient gardening design that maximizes space and enhances soil health. This circular garden typically features a central compost bin, which not only serves as a nutrient source for the surrounding plants but also helps retain moisture. The garden is easily accessible from various angles, making it user-friendly and suitable for gardeners of all abilities.
The design usually resembles a pie-shaped segment with a path or access point that allows you to reach the center compost bin. Keyhole gardens are particularly popular in areas with limited water supply, as the structure promotes water conservation through efficient irrigation and moisture retention in the soil.
How do you start a keyhole garden?
To start a keyhole garden, you’ll first need to choose a suitable location with plenty of sunlight and good drainage. Begin by marking out the circular shape, typically around six to eight feet in diameter, with the compost bin in the center. Once you have your outline, clear the area of any grass, weeds, or debris.
Next, you can build the walls with materials such as stones, wood, or bricks, ensuring they are at least 18 inches high. Fill the base with layers of organic materials, including kitchen scraps, yard waste, and soil, while integrating the compost bin in the center. After this, you can plant your chosen seedlings in the surrounding space, observing proper plant spacing and layout for optimum growth.
