Keyhole gardens are circular or oval-shaped beds with a unique 'keyhole' shaped path that allows easy access to the center. This design is inspired by traditional African gardens and is characterized by a central compost pile that provides nutrients to the plants. The keyhole shape also facilitates efficient watering and weeding, making it a low-maintenance and eco-friendly gardening solution.

Before you start building your keyhole garden, consider the size, location, and plants you want to grow. Here are some design ideas to inspire you:

Size and Shape

Keyhole gardens can range from 6 to 12 feet in diameter, depending on the space available and the plants you want to grow. The keyhole path should be about 18 inches wide to allow easy access. The most common shape is a circle, but you can also create an oval or kidney-shaped garden for a unique look.
