Materials and Tools Needed
To construct a keyhole garden, you will require several materials and tools. These include:
- Shovel
- Wheelbarrow
- Trowel
- Hoe
- Heavy-duty stapler (optional)
For the outer walls, you can use:
- Stacked stones
- Cinder blocks
- Corrugated metal
- Shipping pallets
- Old fencing material
You will also need around 5 wood stakes measuring 3-5 feet long. To attach chicken wire or other permeable material sheeting, J-Clips, heavy-duty staples, or bailing wire will be necessary. Additionally, gravel, crushed stone, or another loose material is needed for aeration. If desired, you can add red wigglers.
Other required items include:
- Raised bed filler
- Weed block (optional)
- Seeds or seedlings
- Half a yard of loam soil
- Airflow tube (optional).
Building the Keyhole Garden
When constructing a keyhole garden, start by clearing a level circular area that is approximately 6 feet in diameter. Stake a 3-foot string in the center and trace a circle around it to mark the perimeter.
Arrange the materials for the garden’s walls around the perimeter, leaving a pathway to the center. Use stacked materials to build the outer walls of the garden, which will prevent soil from leaching out. Fill any gaps in the walls with cardboard or other materials to keep the soil from escaping.
In the center of the circle, mark out an 18-inch diameter area for composting. Place five wooden stakes around the perimeter of the composting area and attach chicken wire to them using durable materials. To promote aeration, add loose gravel or broken-up shipping pallets at the bottom of the compost pile, followed by topsoil. Fill the compost pile with a mix of brown and green waste, excluding meat and dairy products. If desired, you can create an airflow tube to improve aeration.
Ensure that the garden slopes away from the compost pile so that water and nutrients can filter into the garden. Make sure that the outer edge of the garden wall is lower than the outer edge of the compost pile.
Preparing the Soil and Keyhole Garden Design
- Allow the soil to settle for a week before planting. This will create optimal conditions for growth by allowing any disturbances caused during the construction of the keyhole garden to settle and the soil to become more stable. It also gives time for excess moisture to evaporate, preventing waterlogging and root rot.
- Design your keyhole garden for efficiency and productivity. Consider the size and shape of your garden to ensure easy access to all areas. Circular gardens are the most efficient, but you can adapt the shape to fit your space.
- Incorporate layers of well-draining materials like stone, twigs, broken clay pots, cardboard, newspaper, straw, wood ash, compost, and topsoil. This layering technique promotes proper drainage, aeration, and nutrient availability for plants. It also helps conserve water and reduces the need for frequent watering.
Benefits of Composting and Soil Conservation
