A keyhole garden is the ultimate raised-bed planter with a great many advantages.   They are popular in hot, dry places, although they will improve growing conditions in just about any climate.

What's a Keyhole Garden? 

First of all, from a bird's eye view keyhole gardens are shaped like a keyhole because a notch like a pie slice is cut into a round garden bed.   A hole in the center holds a composting basket that moistens and nourishes the soil.  They were first made popular in Africa but are catching on in Texas and other hot, dry places, although they will improve growing conditions in just about any climate.

- They hold moisture well due to an active compost pile placed in the center of the round bed.  Thanks to the moisture-retaining nature of compost, keyhole gardens require significantly less water than a conventional garden.

- They also get and retain nutrients very well because of this active compost pile in the center, therefore no fertilizer is needed.

-The use of paper compost materials to layer the bottom of the garden, such as cardboard and other paper products, provides carbon, nitrogen and air to the soil.  Plus that kind of material would have ended up in the trash anyway, so there’s less waste.

-They take out the backbreaking part of tending a garden by being conveniently waist high (generally they are constructed to be about 3 feet high).

 - You can easily add a frame to the keyhole garden design to support a shade cloth during the hottest months.  The frame could also be covered in early spring with plastic sheeting to create a greenhouse effect.
