Autumn/Winter Treatment

Stronger grass to cope with the winter

The autumn and winter climate will eventually slow or stop the grass growing, so this micronutrient treatment is different in that it doesn't encourage growth. Instead, it's designed to stimulate chlorophyll activity for a stronger, more robust lawn that's better able to cope with the rigours of winter.

The treatment dehydrates any moss that may have built up, helping to control it by slowing down its activity. By keeping the moss spores to a low level, it also prepares your lawn for any mechanical work.

How it works

As growth slows down, the combination of Nitrogen, Potassium, Calcium, Magnesium and/or Phosphorous is no longer necessary. Now we need Iron to support the development of chlorophyll, promoting a greener colour, strengthening the grass and also aiding recovery after any mechanical work.

Iron also helps to dry out moss by scorching it so it can't absorb moisture. This process breaks down the plant structure which enables moss to be removed from the lawn and allows the sward to develop in the spring.
