The Rasensamen Nachsaat fulfills this purpose excellently.

Below we briefly explain the functionality of the test product:
The most important function of the product is the sustainable and rapid closure of lawn gaps with a high-quality, fast-germinating grass that withstands high loads. 

As part of our quality inspection, the physical products were tested for functionality, durability, and user-friendliness.
The results show that the seeds generally germinate well, but in some areas, complete germination is not achieved.
The durability of the grasses meets the requirements and ensures high resilience even with intensive use.
The shade tolerance of the mixture is limited in some areas, which affects germination there.
The ease of care is high, as the grasses are less susceptible to weeds, moss, or diseases.
Finally, the Nachsaat quickly fills the gaps, resulting in an even and dense lawn appearance. Overall, the test report shows positive results, although there is still potential for improvement in certain areas.

The tested quality features meet the established requirements of quality testing.
