Maybe you ask yourself what you could do with these empty places until autumn arrives. Our recommendation: green manures. You can buy a sack of green manure in almost every garden centre. Green manures are different plant seeds which have the characteristic to spread out rapidly. Common examples of green manure plants are: red clover, blue lupine or oats. When deciding to use green manure, bare beds thrive on an organic fertilizer. This will then transform them into a beautiful green or a colourful carpet of plants.
The benefits of green manure are remarkable: It turns bare places into green ones and loosens up the soil. Therefore, the crumb structure is enhanced and counteracts the compaction of the soil. The humus that was created by the remains of the old plants is enriched by green manure and provides important nutrients. Furthermore, the water storage in the soil is improved so that growing conditions for the next season will improve. Many hobby gardeners know the problem of unwanted weeds. Green manure plants help to suppress the weed growth. It is even possible to combat soil pests and diseases. Additionally, green manure prevents drying out of the soil and also soil erosion.
You can plant the green manure seeds during the whole vegetation phase. However, it is recommended to do this in August. At first you have to remove the old plants. Then you scatter the seeds whilst making sure to keep the beds moist.
When the flowering season is over, before you start planting seeds, you must remove the above-ground parts and mix them with the soil. After this treatment, you can start thinking about what you would like to grow in this spot for the coming planting season.
