Berlin (dpa / tmn) – They are rocky, barren and bad for biodiversity: Gravel gardens have a bad reputation. The good thing: in just a few simple steps, the stone desert becomes an area full of wild flowers.
- In the test: Small folding saws are sufficient for occasional gardening
- Not a mysterious disease: Plants get sunburned too
- Plant a tree, save the world: Protect the climate as a hobby gardener
- Herbs and beets from the garden: Now prepare the winter harvest in the vegetable patch

And not even all of the gravel has to be driven off, according to the German Nature Conservation Union (Nabu). Because many of the native wild-growing plants love stony, poor soils. Once they have conquered their new location, the new bed needs little maintenance thanks to self-sowing. That’s how it works:
Remove fleece or film: If there is a fleece or plastic film under the gravel, it should be removed first. This makes the soil permeable to air and water again.
Fill in with sand: Fill in the gaps in the gravel with unwashed sand or gravel so the plants can take root. Nabu recommends around 50 liters per square meter here.
Incorporate compost: 20 liters per square meter are sufficient here. It is best to use quality-assured green waste compost. Mix coarse gravel, sand and compost with the rake. If necessary, add compost, the top layer should be fine-crumbly and evenly at the end.
The soil is now ready for sowing. A wildflower seed mixture is recommended for colorful and poor meadows. Sow the seeds, press them down and keep them moist for three months. In addition, wild perennials can be planted that are suitable for dry locations.
