Herbal spirals are a great way to fit many plants in a small space. In addition to ready-made spirals from the hardware store or garden center, hobby gardeners can also easily build the practical planter themselves.
For such a herb spiral you need stones in sufficient quantity and enough free space in the garden or on the terrace. If a pond is to be created, garden enthusiasts also need a bucket or foil. Do-it-yourselfers need gravel for the drainage layer, compost, humus and sand.
