Keyhole Gardens are a brilliant garden design that lets you compost and grow vegetables in the same garden! This square 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 enclosure 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 enclosure to increase drainage and encourage nutrient uptake in your new garden bed! This garden is easily assembled in a matter of minutes without the use of tools. Made from food-grade, phthalate-free, BPA-free polymer materials.
