What is a Herb Spiral?
Herb spirals are a type of garden design that utilizes a spiraling path to maximize growing space. The spiral is constructed of stone, brick, or other materials and is filled with soil and compost. The spiral shape allows for a variety of growing conditions (also known as microclimates), including different levels of sunlight, moisture, and drainage, which can be used to cultivate a wide range of herbs and other plants.
Herb spirals work by taking advantage of the natural slope of the spiral to create different microclimates within the spiral. The top of the spiral is exposed to the most sun and is best for growing sun-loving herbs such as rosemary and thyme. The bottom of the spiral is shaded and retains moisture, making it an ideal place for moisture-loving herbs like mint and chamomile.
