Spiralling herbs
Building a herb spiral provides a space-saving way to cultivate a selection of edible plants close to the home. First, the ground is raked level, then a garden cane is pushed into the centre of the chosen area. A piece of string tied from this to a second cane allows the marking of an accurate circle for the base of the spiral. The string and second cane are removed, and a small plant pot or cane topper is placed on the central cane to prevent eye injuries while building. Large pieces of stone are laid out to form the wall of the spiral. Placing the entrance to the north allows plants to be positioned according to their sun, shade and water needs. Once a full course of stones has been laid, soil and gravel are added to fill the spiral. The height of the walls is gradually built up, with more soil and gravel added as necessary. The central cane is removed and a final stone added at the top. Next the chosen herbs are laid out in their pots to decide on the order of planting. Once all are positioned according to their needs, they are planted out. Smaller varieties, such as thymus ‘Silver Posie’, are planted between the stones in the walls, held in place with earth and stones. When all plants are in place, the spiral is thoroughly watered.
