Main highlights

Rich regeneration: Vital nutrients, enzymes and sugars of our organic lawn fertiliser ensure healthy soil life and revitalise heavily stressed and depleted areas. Thanks to the good nutrient supply and loosening of the soil with the organic lawn fertiliser, water can be stored for longer and prolonged dry periods are survived.
Instructions for use: Our organic fertiliser can be used all year round for new plants and in existing areas from March to October. Approximately 200m² of lawn can be fertilised with 10.5 kg. Spread the bio-fertiliser on the dry lawn 1 to 2 days after mowing. Fertilise in March / April and in June / July about 30 g per square metre. Increase to 3 applications on growing and intensive surfaces. Last application should be no later than the beginning of October.
Extensive effectiveness: Nitrogen is considered to be the engine of lawn growth. The high nitrogen content of our organic lawn fertiliser ensures both short-term and lasting effects: While about 50% of the nitrogen is effective in the first two weeks, the other 50% is released later and enables a balanced fertilisation and long-term effect.
Direct use: Over-fertilisation is impossible with our organic lawn fertiliser. In addition, children and pets can walk on your lawn as soon as the easily water-soluble and pleasantly scented granules have dissolved after watering.
2021 Competition Winner: Test the comparison winner (grade 1.5). Our organic fertiliser made exclusively from vegetable raw materials works and has a lasting effect on all sports and ornamental lawns. The fertiliser symbioses with your soil to form humus in a short time and, by loosening the soil layer, enables the roots to grow quickly and thrive.
