Both beautiful and useful, and the very latest trend. In 2 sizes: approx. 200 x 150 cm and approx. 110 x 90 cm. The mesh panels are push fitted (not screwed). The space required is about 3 m² (1.5 x 2 m), with a maximum height of 80 cm. A planting scheme is supplied with the kit. A herb spiral imitates various different climate zones, in order to create perfect growing conditions for the plants. The three-dimensional spiral shape and the capacity of the stones for storing heat create four zones, from water to moist to normal to Mediterranean (Ill. 1: A, B, C and D). The spiral should be aligned north-south, in order to make full use of sunlight. A water zone can be created by making a miniature pond in the lowest section. The spiral can also be used as a watercourse or spiral-shaped raised flowerbed. Stones, watercourse and plants are not included in the delivery.
