Keyhole Gardens are a brilliant garden design that lets you compost and grow vegetables in the same garden! The Urban Keyhole Garden has the perfect urban appearance, matching modern black powder-coated aluminum corners with contrasting food grade PVC composite boards for longevity. The high, contained sides prevent soil erosion and make it easy to add an attractive, thriving garden to any yard or deck. The rectangular shape makes it easy to tend plants from any angle, and the fact that it's a keyhole means you'll be gardening smart -— growing more, while working less. Keyhole gardens use far less water than in-ground gardens (up to 70% less) and are perfect for drought-prone areas. The included composting basket means you can use daily kitchen scraps (reducing household waste by up to 30%) to improve the garden’s soil and nourish your vegetables at the same time. Make sure you add stones or broken pottery at the bottom of your compost basket to increase drainage and encourage nutrient uptake in your new garden bed! Easily assembled in a matter of minutes without the use of tools. All posts slide and lock into place easily and conveniently! Compost basket dimensions are 12 in. x 12 in. x 24 in. Ships in two boxes.
