Due to their special structure, different site conditions prevail in the different areas of a herb snail or herb spiral, which best correspond to the respective requirements of the selected herbs. When creating the stone spiral, the many different types can be placed in the most suitable place.
A herb snail should get plenty of sun
Most herbs love the sun
Most herbs need sun, which is why the herb snail should ideally be set up in a sunny location. The bed is divided into several zones with a wide variety of substrates from lean and dry to nutrient-rich and moist. Different conditions arise in relation to light and shade as well as humidity. In addition, the herbs benefit from the heat that the stones store in the sun and slowly release again. This heat storage even reduces light night frosts.
The different zones
The upper zone of the herb spiral is in full sun, the soil is permeable, lean and dry. The sunny to partially shaded middle zone offers a moderately nutrient-rich and dry location, while the sunny and nutrient-rich lower zone offers a moist substrate.
tips
Since the location of the herbs should be close to the house or kitchen, the herb spiral is often included in the terrace design.
