How to make a herb spiral
Most herbs need a lime-rich soil, so mix it with extra lime.
Herbal shrubs should be cut back regularly so that they do not become too woody and crowd each other. The herb spiral is 2.5 metres in diameter, it is better not to make it any smaller as it will dry out during long absences. You can also choose to place a built-in sprinkler in the middle, which makes it easy to spray all the herbs. On the side you can put tree trunks (preferably oaks) that you can inoculate with edible mushrooms. And make sure it is nice and close to the kitchen.
All you need to make your own spiral is soil mixed with compost and stones to build the spiral with. You can even start with a container for growing watercress (see drawing).
- Choose a spot in the garden with enough sunlight (at least five hours a day).
- Put a stick in the middle of the spot where the spiral is to be placed.
- Tie a one-metre rope to the stick and tie another stick to the end.
- Draw a circle in the ground.
- On this line, build a wall of stones about 30 cm high. Do not make it completely round, but turn inwards a little before the end. From the second round, stack one or two stones higher.
- Repeat this towards the centre until you have three levels and the spiral is to your liking.
- Fill everything with soil and water well.
- Let the spiral sink in before planting. Only when it is sturdy enough can you start planting herbs.
