End of Season Treatment

Toughen up your lawn during the harsh, cold winter months with an iron-based micronutrient spray that will help to inhibit moss growth

What is the End of Season Treatment?

It is important not to forget caring for your lawn as winter takes hold. TopGrass will provide ongoing moss treatment to the lawn, during any harsh weather conditions so it can transition smoothly into new spring growth. Like the Late Season Treatment, this iron-based micronutrient spray will strengthen and toughen up the lawn during winter months, whilst any new moss growth receives a fresh dose of iron to blacken it and induce dehydration.

The End of Season Treatment is included in these packages

£10.42/Month

£14.50/Month

Enhanced Package

£21.58/Month

How does our End of Season Treatment work?

As growth remains slow at this time of year, the combination of extra Nitrogen, Phosphorous, Potassium and macro-nutrients are not required - these will be introduced in the Season Starter Treatment. Iron is needed to promote the production of chlorophyll, ensuring a vibrant green colour within the grass plant. Dehydrating the moss in the lawn will prevent the plant from retaining moisture and eradicating the conditions in which it needs to thrive.

There are many potential causes for moss to appear in lawns, including mild and wet winter conditions, excessive shade, compacted soils, poorly drained soils, low soil fertility, high or low soil pH, and poor air circulation. Our Winter Treatment takes a dual course of action in providing extra soil fertility through the micro-nutrients, inhibiting moss encroachment with a fast-acting liquid application.

Our End of Season Treatment formula comprises:

  • Iron sulphate to green up the grass plant, and to dehydrate and blacken moss
  • Iron is a micro-nutrient that helps to harden and strengthen the grass plant, making it less susceptible to disease and damage during harsh seasonal conditions.

Summary

When?  January - February

What?  Iron-based micro-nutrient spray.

Why?  To dehydrate and blacken new moss growth, harden the grass plant against harsh winter weather, strengthen root structure and improve colour.

FAQ's

This treatment is typically applied between January and February, when grass growth is minimal and moss is most likely to thrive.

The End of Season Treatment is a standard part of every TopGrass lawn care package, which includes the Basic, Standard and Enhanced Packages.

  • Strengthens grass against frost and disease
  • Improves lawn colour with iron-induced chlorophyll production
  • Suppresses moss by dehydrating it
  • Prepares the lawn for healthy spring growth

Absolutely. Iron promotes chlorophyll production, which enhances the lawn’s green colour—even in cold weather.

It won’t eliminate moss entirely, but it blackens and weakens new moss growth, making it easier to control in future treatments.
