          Keyhole Garden Tutorial

          Here’s another small space garden method to try. Dr. Deb Tolman is the original creator of this concept of rolling a garden bed and compost into one. It’s based on the lasagna garden method where layers of recyclable materials are used as well as being water conservative.

          Follow these simple steps to create your own and you’ll have a veggie bed that is a pretty as it is Eco sensitive.

          What is a Keyhole Garden?

          A Keyhole garden is a raised bed that uses minimal space, recycled materials and combines a compost system and garden bed into one.

          It’s a circular shape with a slice taken out to allow for easy access to the compost basket in the center creating the keyhole shape. Build the sides out of wood, cinder blocks or bricks. Any type of material could be used that would allow you to build up the sides.

          Use two sticks with a 3′ string tied between them to measure out your shape. Place one in the center and draw a line turning around the center point. Build your sides with your chosen material up 2 feet. We used 48 cinder blocks in our example.

          Similar to the lasagna style, a layer of rocks, twigs, branches and even old broken pots can be placed in the bottom to allow for drainage. Add layers of cardboard and the newsprint between compost and then fill the top half with straight soil/compost mix.

          A ‘compost basket’ made of wire ( chicken wire or a more heavy duty gauge ) is at the center as you build your layers. We decided to use some old moss as a screen in our demonstration garden to create a permeable layer between soil and compost.

          Slope your soil away from the basket towards the edge of your bed. The compost baskets gets watered, and this slope direct the moisture out from the basket and through the bed. The water carries nutrients from the decomposing compost material, thereby feeding the soil and irrigating it at the same time.

           

          Plant your bed with any vegetables you desire. Have fun mixing edible flowers or even puttint a few poles curved over the bed for some climbers. Try planing in a twisting pattern to add more interest.

          1. My mom used to put wire bins like that in her flower garden for her kitchen scraps. The flowers grew so lush around them that they disappeared. One year, some potato peelings fell out and started to grow. Dad laughed at first, but Mom’s volunteer potatoes did better than the ones he planted in his veggie garden on purpose. This was 50 years ago, before composting was cool.

            • LOVE IT! Composting is easy to do. A lot of ‘stuff’ out there makes it seem complicated, but Mother Nature has been doing it since the earth was formed with no special tricks at all.

          2. So you don’t put anything but compost materials in the middle? Just wondering if a bottom layer is needed :) also, do you think this might work as just a quarter circle if we have access to the corner point?

            • Yep, just compost… no weeds. You can add grass clippings and other garden clippings as well. I don’t see there being a problem making a smaller slice ;)

            • Squirrels are a real pain! Sometimes it’s better to join them then to fight them. Buy bag of cheap plain peanuts in the shell or some other type of food they love and placing that in the opposite side of your garden will keep them away from the things you want them to leave alone, worth a shot.
