Small mountain landscapes are modeled in the rock garden. In addition to the selection of stones, suitable perennials play an important role.© Franz Bogner - Fotolia.com A rock garden, that can be a gravel garden, a planted dry stone wall or a rubble garden. They are planted with upholstery, sedum species, ornamental grasses, flowering perennials or onion plants. It can be used to model mountain landscapes or to represent habitats that have been recaptured by the flora.
The ideal location for a rock garden is a gentle slope to the south. On the one hand, the rock garden perennials have ideal growth conditions, on the other hand, the stones store heat during the day, which they give off at night. This creates a microclimate in the rock garden, which benefits the perennials and small animals. Rock gardens can also be created in shady areas. They are preferably planted with ferns, hostas, elf flowers and bergenias.
Which stones for the rock garden?
In the most common cases, large stones, stone or gravel gravel are the basis of rock gardens. However, stone is not just stone. There are a few things to consider when choosing:
- Use large and expressive stones - not too many.
- Choose light-colored stones that create a striking contrast to the green and the colors of the flowering perennials.
- The shape of the stones can be different: round or angular.
- The stones are distributed without a recognizable pattern. This makes the rock garden look natural.
- Let the stones into the ground a little - they will find enough support on the surface of your rock garden.

Plant perennials in the rock garden - prepare the soil well
Before you create a rock garden, you should check the quality of the soil. It should be well drained to avoid waterlogging. Long-lasting wetness causes root rot in the stone bed perennials.
- The selected area for the rock garden must be thoroughly cleaned of weeds and their roots. After all, weeds should not sprout between the slowly growing rock garden shrubs.
- If you are already working on the ground, you can - if you wish - dig out hollows or a future stream. This gives your rock garden a special structure.
- Now cover the earth with an approximately 20 centimeter thick layer of grit or round gravel. This serves as drainage for optimal water drainage from precipitation.
- Now place fleece over the drainage layer. This prevents earth from later seeping into the drainage and silting it up.
- Now the stones can be laid out and the gaps can be filled with a floor substrate. One third of this consists of humus. Otherwise, the soil in the spaces should be low in nitrogen and loose.
Design the rock garden with perennials
