Warning: Do not apply on damp lawn (dew/rain), risk of burns. Keep away from children. Store in a cool, dry place away from light and moisture.
Uniform granules: grain size 2-5 mm: suitable for all spreaders or for hand distribution, do not form piles, do not hinder robotic lawnmowers and are activated by simple watering.
Triple power potassium calcium magnesium: potassium 6% strengthens cell walls and supports the water balance; calcium 5% strengthens roots and tissue; magnesium 4% intensifies photosynthesis for a denser and more resistant lawn.
Starter fertiliser for sowing: NPK 15-25-6 especially for the initial phase, promotes deep and even root growth and ensures fast germination as well as a homogeneous lawn cover. Suitable for sowing and reseeding, can be used all year round.
INSTANT ROOT EFFECT: The high phosphorus content 25% stimulates root development in the first weeks and reduces bald spots. The nitrogen provides the necessary starting energy for growth.
Application program: application 30 g/m². Apply the starter fertiliser before or directly after sowing, lightly incorporate or water; if reseeding, sprinkle and water after a light cut. After that, the lawn needs three seasonal fertilisations: in spring with 20-0-12, in summer with 6-0-28 and in autumn again with 20-0-12.
