NPK nutrient breakdown for Totally Autumn lawn fertiliser

Keeping up appearances

Added magnesium improves photosynthesis and ensures a rich green colour well into autumn. Combined with the right height of cut, your lawn will look picture-perfect even as the weather turns.

Healthy green lawn maintained through autumn

50% slow release

Cleverly formulated to be 50% slow-release: your lawn gets a nutritional boost in early autumn to help prevent red thread, followed by a slower, prolonged feed into winter that helps guard against diseases like fusarium. Totally Autumn keeps your lawn healthy.

Frequently asked questions

How quickly will Totally Autumn start working?
You should start to see results within 4-7 days from when the product is watered in.
When should I apply autumn lawn feed?
Apply Totally Autumn from late August through October, before the first hard frosts. This autumn lawn feed hardens the grass for winter while it's still warm enough for the roots to take up the nutrients.
Can I spread this fertiliser by hand?
Yes - you can spread this fertiliser by hand, but we recommend using a quality fertiliser spreader to ensure the most even application. Each purchase comes with instructions on how to spread it for the best results. Check out our collection of fertiliser spreaders for all-size lawns. Whatever you choose, we recommend wearing gloves when handling fertiliser.
How much fertiliser do I need?
Each 1 kg bag will cover 30m2. Choose your lawn size from the drop-down menu and we will automatically select the required amount of fertiliser your lawn needs. Not sure how big your lawn is? Don't panic, try our online lawn measuring tool and measure the size of your lawn from the comfort of indoors! If you have a large area to cover, we can supply 20kg bags - please get in touch with your requirements.
How long will this lawn feed last?
This controlled-release fertiliser will last up to 3 months (12 weeks). This does depend on a few factors such as grass type, weather conditions, whether you collect grass clippings or mulch, application rate, etc. All of our seasonal fertilisers are slow-release, which is a more sustainable and environmentally friendly practice, as there are fewer nutrients lost to leaching.
