      Frequently Asked Questions

      FAQs

      Q: How quickly will Winter's Coming winter lawn fertiliser start working?

      A: You should start to see results within 4-7 days from when the product is watered in.

      Q: I have a very large area that needs to be fed. Can you supply large quantities of lawn fertiliser?

      A: If you want to order larger quantities, feel free to contact us for a customised quote. We can provide lawn feed in most quantities as required, including by the pallet.

      Q: Can I spread this fertiliser by hand?

      A: 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.

      Q: How much fertiliser do I need?

      A: Each 1 kg bag will cover 20-30m2. 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 our 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.

      Q: How long will this lawn feed last?

      A: 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 less nutrients lost to leaching.
