The garden spiral is like a snail shell, with stone spiraling upward to create multiple micro-climates and a cornucopia of flavors on a small footprint. Spirals can come in any size to fit any space, from an urban courtyard to an entire yard. You don’t even need a patch of ground, as they can be built on top of patios, pavement, and rooftops. You can spiral over an old stump or on top of poor soil. By building up vertically, you create more growing space, make watering easy, and lessen the need to bend over while harvesting. To boot, spirals add instant architecture and year-round beauty to your landscape: the perfect garden focal point.
One of the beauties of an herb spiral is that you are creating multiple microclimates in a small space. The combination of stones, shape, and vertical structure offers a variety of planting niches for a diversity of plants. The stones also serve as a thermal mass, minimizing temperature swings and extending the growing seasons. Whatever you grow in your spiral, it will pump out a great harvest for the small space it occupies. I’ve grown monstrous cucumbers in my large garden spiral, with one plant producing over 30 prize-size fruits. The spiral is a food-producing superstar!
Stacked stones create perennial habitat for beneficial critters, such as lizards and spiders that help balance pest populations in the garden. The stone network is a year-round safe haven for beneficial insects and other crawlies that work constantly to keep your garden in balance—and you in the hammock. A little design for them up-front pays big, tasty dividends later.
