Herb Spirals, Mandala & ‘Hoist-ariums’
Herb Spirals or herb mandalas are a popular and successful permaculture element. A well planned herb spiral can provides a variety of positions (sun, shelter, and shade). It will also provide plants with different levels of moisture (the top is dry and the base boggy). Most herb spirals are usually 1 meter high and contain all the plants which are often used such as : mints, thyme, marjoram, rosemary, sage, basil etc.
It is a simple but effective design.
The center of the herb spiral should be elevated and the ground falls as the spiral unfurls. This allows you to plant, dry soil plants like rosemary at the top and water loving plants at the bottom such as watercress and water chestnuts.
You should be able to reach all the parts of your herb spirals or herb mandala without having to step onto it.
