A rock garden, that can be a gravel garden, a planted drywall or a scree garden. They are planted with upholstery, sedum species, ornamental grasses, flowering perennials or bulbous plants. In this way mountain landscapes can be modeled or habitats reproduced, which were recaptured by the plant world.

The ideal location for a rock garden is a gentle slope in a southerly direction. 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 release at night. This creates a microclimate in the rock garden, which benefits the perennials and small animals. Rockeries can also be created in shady areas. Preferably, these are planted with ferns, funenia, elven flowers and Bergenia.

Which stones for the rock garden?

In most cases, large stones, stone or gravel gravel are the basis of rock gardens. However, stone is not just stone. There are some things to keep in mind when choosing them:

  • Use large and expressive stones – not too many.
  • Choose bright stones that create an eye-catching contrast to the green and the colors of the flowering plants.
  • The shape of the stones can be different: round or square.
  • The stones are distributed without recognizable pattern. This makes the rock garden natural.
  • Let the stones sink into the ground – they will find enough hold on the surface of your rock garden.

»Tip: A small stream gives your rock garden a special flair.

Plant perennials in the rock garden – prepare the soil well

Before you create a rock garden, you should check the quality of the soil. The should be well drained , so that waterlogging is avoided. Prolonged wetness causes root rot in the stone-bed bushes.

  1. The selected area for the rock garden must be thoroughly cleaned of weeds and their roots. After all, we do not want to drive out any weeds between the slowly growing rock garden perennials.
  2. If you are already at the ground work, you can – depending on your wishes – also dig basins or a future watercourse. They give your rock garden a special structure.
  3. Now cover the earth with a layer of chippings or round gravel about 20 centimeters thick. This serves as a drainage for optimal water removal from precipitation.
  4. Now lay fleece over the drainage layer. This prevents soil from seeping into the drainage later on and silting it up.
  5. Now the stones can be laid out and the spaces filled with a soil substrate. This consists of a third of humus. Otherwise, the soil in the interstices should be low in nitrogen and loose.

Design the rock garden with perennials

A rock garden looks attractive when stones and plants are in harmonic relationship. Stones and plants should come into their own. Therefore, it is advisable to select carpet and upholstery-forming perennials for the rock garden. With onion plants you can give your rock garden an additional structure.
