Warning: 4. Keep out of reach of children. Store in a cool, dry place, protected from light and moisture.
Triple power potassium calcium magnesium: potassium 12% strengthens cell walls and water balance; calcium 3.5% strengthens roots and tissue; magnesium 2.5% increases photosynthesis for a denser, more resistant lawn.
Lawn fertiliser for spring and autumn: NPK 20-0-12 activates the lawn after winter, promotes growth in spring and regenerates it after summer, so that it goes colour-intensive and dense into the first frosts.
Instant revival: quickly available nitrogen ensures rich green in a few days, while the long-term component provides the lawn for weeks without growth spikes or yellowing.
Homogenic granules: grain size 2-5 mm: run through any spreader or can be applied by hand, do not form piles, do not hinder the robotic lawnmower and become active quickly after light watering.
Application program: application rate 30-35 g/m². Apply this fertiliser once in spring (March-June), in summer (June-August), apply the summer fertiliser 6-0-28 once and repeat the application of this fertiliser once in autumn (September-November). For new or re-seeding, supplement the starter fertiliser for quick rooting.
