Autumn and Winter Lawn Fertiliser Products

Our A1 Lawn Autumn Winter Fertiliser is a potassium rich lawn feed, designed to give your grass all the nutrients it needs to keep it lush and healthy throughout the tough colder months.

Amvista G9 is the classic autumn lawn feed, releasing nutrients over 6–8 weeks, so it can be applied more than once over the autumn and winter period.

The higher-strength G8 Long Life Lawn Fertiliser is resin-treated. A single application of this 2.5x stronger product releases nutrients evenly over 4–5 months, helping grass remain healthy through winter and into spring.

If a liquid option is preferred, Amvista L2 Fertiliser contains iron, sulphur and nitrogen, and will harden turf and deter moss.

When should you apply autumn lawn fertiliser?

The best time to start is usually around September, before the soil temperatures fall too low and growth stops.

What is the best way to apply my autumn and winter fertiliser?

Using a spreader is one of the best ways to speed up the application of your grass feed. We offer a range of fertiliser spreaders for you to choose from.

Can you fertilise lawns in the winter?

Yes, you can fertilise your lawn in the winter. However, fertilisers should not be applied to frozen grass, as they can't be absorbed properly.
