Some projects are born out of curiosity and intrigue, while others are born out of necessity. When we discovered that our yard had a roadbed running under a good portion of it—making in-ground planting impossible—we knew we had to get creative to use the space for gardening. We built raised beds for vegetable gardening, which was fairly straightforward, but while researching alternatives, one particularly interesting idea stood out: an herb spiral.
The concept of an herb spiral is simple yet effective. Soil is mounded highest in the centre (or top) of the spiral and gradually becomes shallower toward the outside edge, or tail. This creates a range of growing conditions within a small footprint. Herbs that prefer drier conditions are planted at the top—such as rosemary (Rosmarinus officinalis)—while moisture-loving herbs, like parsley (Petroselinum crispum), are planted toward the bottom.
My husband and I love projects and are avid do-it-yourself gardeners, and I would rate this project as a relatively simple one. It can become more complex if you choose to build a tall spiral or use materials such as bricks or mortar. By keeping the spiral smaller and using simple materials, the project remains very manageable. An herb spiral requires only a few basic materials; in our case, stones, cardboard, and soil. We made a trip to a local landscape supply company and hand-picked medium-sized black granite stones. We estimated how many we would need and, by some miracle, ended up with exactly the right amount. For soil, we chose a four-way mix, which provided good structure, drainage, and organic matter for a variety of herbs.
