A keyhole garden is a circular raised garden bed with a notch or “keyhole” shape in its structure that allows for easy access to the entire garden. At the center is a compost basket where organic materials are added, which enriches the soil as it decomposes. These gardens are particularly popular in areas with poor soil, limited water availability, or small spaces.
Why Build a Keyhole Garden?
1. Water Efficiency:The compost basket in the center collects and distributes moisture, reducing water usage. This makes keyhole gardens ideal for arid climates or areas where water conservation is important.
2. Nutrient Recycling:
Organic materials, such as kitchen scraps, are composted directly in the garden. Nutrients from the compost are distributed through the soil, providing a continuous source of fertility for plants.
3. Space Efficiency:
Keyhole gardens are compact, making them a great solution for urban or small spaces. Their circular design ensures maximum growing area with minimal footprint.
4. Easy Accessibility:
The keyhole shape allows you to reach all parts of the garden without stepping on the soil, preventing compaction and improving plant health.
5. Adaptable to Poor Soil:
Since the garden is built above ground, you can create rich, fertile soil layers, bypassing poor native soil conditions.
6. Eco-Friendly:
Keyhole gardens promote sustainable gardening by utilizing household waste for composting and reducing reliance on chemical fertilizers.
