Maybe you ask yourself what you could do with these empty places till autumn arrives. Our recommendation: green manures. You can buy a package of green manure in nearly every garden center. Green manures are different plant seeds which have the characteristic to spread out rapidly. Often used green manure plants are for example red clover, blue lupine or oats.
When deciding to use green manure, bare beds on one hand enjoy the pleasure of an organic fertilizer. On the other hand the beds will be transformed into a beautiful green or 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. Than you scatter the seeds and make sure to keep the beds moist in the beginning.
When the flowering season is over, but before they start building seeds, you have to 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 in the coming planting season.
