Why exactly this composition.

Organic nitrogen and amino acids that are released very slowly.

Bio Booster is an organic high-end granular fertilizer (NPK 13-1-2) with 30% amino acids and 62% organic matter. The amino acids are released very slowly: Bio Booster works for 3 to 6 months. Most of the nitrogen is organic (9% of the 13%). Ideal for anyone who wants to feed their lawn organically.

How to use Bio Booster

When Every 6 weeks during the growing season, March to October.
Combine Granular fertilizers are spread dry. The liquid elixirs from the same season of the lawn calendar can be used alongside.

Instructions for use

  1. Work out how much

    Use 35 to 50 grams per m². The calculator above works out how many bags you need.

  2. Spread evenly

    Spread in one even layer, ideally with a spreader. That way no patches grow faster or slower than the rest.

  3. Watering

    No heavy watering-in needed. In dry spells, water every 3 days for at least 1.5 hours.

  • Please note

    Never exceed the dose: too much feed makes the grass grow too fast or stop growing.

  • Storage

    Store dry, between 0 and 35 °C, out of the sun and frost-free. Reseal opened bags. Take the empty bag to your recycling centre.
