the essentials in brief
- A herbal spiral is usually built from stones and offers herbs ideal conditions
- Herbs need a lot of sun, especially sun-loving herbs are planted at the top
- Depending on the zone, the composition of the soil varies from 50% sand, 50% garden soil (dry zone) to 100% garden soil (water zone)
Material requirements and tools
Traditionally, a dry stone wall made of natural stone gives a spiral of herbs an outer shape and weatherproof stability. Hobby gardeners seldom choose wood as a form-giving frame because it involves regular maintenance work. Plant stones made of concrete for a self-made herb snail are enjoying increasing popularity. The following list of requirements for material and tools is aimed at the DIY construction of a herbal spiral with a pond made of stones:
- Stones (at least as thick as a fist), ideally natural stones, optionally field, brick or paving stones
- Sand, gravel and chalk crushed stone
- Garden, weed or Filter fleece to cover the ballast filling
- Garden soil, Compost soil, Herb substrate
- Plant bags for planting gaps in the outer wall area
- Pond tub (cheaper a mortar bucket) or pond liner
- Herbal plants (for details see planting plan below)
- wheelbarrow
- Hand shovel, spade, Rake, Rake, work gloves
- Folding rule, wooden stakes, string and lime for marking the base

You can adjust this shopping list with simple modifications to individual alternatives. Replace the subsection stones with wood, metal, gabions or plant rings. The conceptual structure with climatic zones, pond, filling and planting is retained, taking into account the particular material characteristics. Please note that if you use alternative materials such as plastic, Corten steel, concrete palisades or Wood, the additional growing area that a dry stone wall or planting stones can provide on the outside is lost to have.

Structure of a herb spiral
Prepare the base - step-by-step instructions
A herb spiral needs a lot of sun
In the garden, the self-made herb spiral deserves a sun-drenched box seat. Most premium herbs thrive as sun worshipers and have an aversion to windy locations. Plan a base with a diameter of about 300 centimeters if at least a dozen of your favorite herbs are to be found at a height of 80 centimeters. Position and Alignment make an important contribution to a premium quality herb harvest. Please choose the location so that the herb snail opens to the south, regardless of whether the special raised bed is round or angular. This is how you prepare the base area in an exemplary manner:
Measure and mark
- Use the folding rule to determine the external dimensions and mark them with wooden stakes
- Stick a longer wooden stick in the center of the surface
- Attach the cord to the wooden stick with knotted wooden sticks at the other end
- Draw a circle with the help of string and wooden sticks
- Mark the turns for the snail shape within the circle with lime or light sand
Please mark the position for the pond where the herb snail opens to the south.
Prepare the soil
- Dig the base one or two spades deep
- Rule of thumb: the higher the herb spiral, the deeper the excavation
- Pour garden soil on the side for further use as a component for filling
- Spread a layer of gravel 10 to 20 cm high as a drainage and wall foundation
- Step on gravel (ideally with Plate compactor(€ 359.90 at Amazon *) condense)
- dig the bottom 40 cm deep for the pond
- Lay a layer of sand on the pond floor as drainage and protection for the liner or pond tub
The best time for the preparatory work and the construction of a herb spiral is in spring, as soon as the ground has thawed. By April / May the planting time for herbs begins, the soil has settled in the bed and is ready for young plants.
Building instructions - step-by-step to the building shell
The prepared base also serves as the foundation for the dry stone wall of a herb spiral. For smooth construction work, all material including tools should be at hand. The following construction instructions give an overview of all work steps, followed by more detailed explanations of the individual construction phases:
- Lay the first row of walls on the gravel foundation (note the markings)
- From the second row of walls, stack the stones with the joints staggered
- Lay the following stone layers 30-50 cm shorter than the previous row of walls
- Pile up crushed stone and gravel parallel to the structure of the wall
- Rule of thumb for an 80 cm high herb spiral: Height of the crushed stone / gravel layer in the core is 50 cm
- optionally cover the gravel layer with breathable fleece (filter fleece)
- Create a pond at the foot of the dry stone wall
Explanations of the individual steps
A herb spiral can be built from natural stones or bricks
For the first row of walls, select the largest stones. Lay the stones close together, ideally slightly tilted and with a slight incline inwards for the best stability. The staggered, inclined laying of the following rows of walls is decisive for the stability of the drywall. Cross joints must be avoided at all costs. Thanks to this construction, you can do without the use of mortar.
Despite the staggered laying technique, small and larger gaps arise between the bricks. These cavities are ideal for planting additional herbs with the help of plant bags. Crevices one to two fingers wide provide sufficient living space for frugal herb plants. If you fill the gaps with herbal substrate while stacking, you can simply do without the use of plant bags. One or the other gap in the masonry remains free and serves Beneficial insects of the garden as a coveted hideaway and place of retreat.
The layer of gravel (optionally lime gravel or rubble) grows upwards parallel to the dry stone wall and reaches a thickness of a good 50 centimeters at the highest point. In the direction of the pond, the layer of gravel gradually decreases in proportion to the falling wall height. We recommend covering with filter fleece so that the subsequent substrate layer does not get between the coarse gravel trickles in, then sags sharply and, in the worst case, makes the drainage useless.
Creating a pond - how to do it right
After the masonry work, you can devote yourself to the small pond system at the foot of your herb spiral. In the 40 centimeter deep, sand-lined pit, lay pond liner or insert a pond tub. Use fist-sized stones to hide the transition from the foil or tub to the adjacent bank area.

Fill the herb snail correctly
The correct climatic zone of a herb spiral is made up of position and filling. In a fully sunny dry zone, Mediterranean herbs only find ideal living conditions when they extend their roots in sandy, dry soil with good permeability. Domestic herbs only develop their unique aroma when they are given a humus, fresh and nutrient-rich soil quality. The following overview summarizes which earth determines the character of the respective climatic zone:
- Dry zone: 50% sand, 50% garden soil
- Normal zone: 30% sand, 30% garden soil, 30% compost, 10% Lava granules
- Wet zone: 50% garden soil, 50% compost
- Water zone: 100 % Compost soil or garden soil
If mixing the various components is too time-consuming for you, you can use commercially available herbal soil and sand. You adjust the proportion of sand to the relevant climatic zone within the herb spiral. In the dry zone, please start with the herb substrate and sand in equal parts. The sand quota decreases gradually in the direction of the wet zone.
Please keep a stock of all soil mixes until the beginning of the planting season. Substrate freshly poured onto the gravel layer sags by up to a third and should be filled up. Laying the filter fleece slows down the process, but not completely. For this reason, a period of at least 2 weeks should elapse between the construction of a herb spiral and the planting.

frequently asked Questions
What is a herb spiral?
A three-dimensional raised bed that simulates the different climatic zones in a very small space is called a herb spiral. A dry stone wall traditionally functions as a frame that winds upwards around a pile of stones up to a back-friendly 80 centimeters. The stone filling serves as drainage up to a height of 50 centimeters, followed by soil as a plant substrate. A herb spiral is similar to a snail shell, so herb snail is another common name. Dry, normal, humid and water zones merge seamlessly and are planted with appropriate types of herbs.
When should you put on a herb spiral?
There is no fixed point in time for building a herb spiral. You can plan the construction work almost all year round, as long as the ground is not deeply frozen. In practice, early spring, ideally a few weeks before the start of the planting time, has proven to be effective. Furthermore, autumn is a wisely chosen date for the construction of a herb snail. By next spring, living microorganisms in the compost portion of the filling have prepared the soil so that freshly planted herbs can grow vital and healthy.
Which herbs belong where in a herb spiral?
In the structure, a herbal spiral with a pond represents four elementary climate zones in mini format.
