Why exactly this composition.
Autumn feeding prepares the lawn for the winter months, so it can form a dense, healthy carpet again in spring.
Autumn Basic is the third and last feed of the year in the Basic line. Fertilize-it believes strongly in potassium to take the grass into winter strong: this autumn fertilizer contains 20% of it, for harder cell walls. Thanks to the polymer coating (33% CRF), it releases its nutrients gradually for up to 3 months, driven by temperature.

Instructions for use
Work out how much
Use 25 to 35 grams per m². The calculator above works out how many bags you need.
Spread evenly
Spread in one even layer, ideally with a spreader. That way no patches grow faster or slower than the rest.
Clear hard surfaces
Blow or brush granules on paths, patios or wood back onto the grass straight away: the iron can stain.
Watering
No heavy watering-in needed: the granules release their nutrients gradually, driven by temperature. 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.
Please note
The granules contain iron: blow or brush granules on stone, patios or wood straight back onto the grass. Do not rinse them off with water, as iron can leave rust stains.
Please note
This fertilizer contains urea, which can release ammonia. Only use it when there is a recognised need.
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.
Precise dosages and tank-mix.
Autumn Basic is spread dry, without mixing.
