Frequently Asked Questions

Can I use liquid fertiliser on all types of lawns?

Yes – liquid fertiliser is suitable for most lawn types and is especially useful when you want fast results or need a precise application.

What are biostimulants and do I need them?

Biostimulants help your grass cope with stress, improve root growth and make better use of nutrients. They're a good addition for tired or high-traffic lawns.

What’s the difference between soil conditioners and fertilisers?

Fertilisers feed the grass directly, while soil conditioners improve the structure and health of the soil beneath – helping roots grow deeper and stronger.

When should I apply lawn fertiliser?

It depends on the product, but lawn feeds can be used all year round. Spring and autumn are key times, but specialist feeds are also available for summer boost or winter protection.

Do I need to adjust soil pH before fertilising?

If your soil is too acidic or too alkaline, it can limit how well grass uses nutrients. Our neutralisers help bring pH back into balance before you feed.
