Hello everyone I just bought a Granular Autumn Lawn food with product date 2020 stamped on bottom. Is this still ok to use or does it go out of date? Thankyou

    Not sure. I never use it, but I expect there's no harm. It might be less effective or something similar. 
    Someone else will hopefully be able to advise more accurately.  :)

    I have never used it either. Over the winter months my grass grows well anyway. It is used at this time of year not to green up the lawn but to feed the roots.

    It depends has it been opened ? Usually if they have been opened it goes off over time due to the fertiliser absorbing moister from the environment . 

    Its worth seeing if it works it'll not do any harm no pesticides involved, it can be difficult to tell if it working or not but if its got iron in that will be a good indicator .

    If the granules are still free-flowing, it should be OK.

    If it has become damp and claggy, put the container in a dry place with the lid off and stir from time to time.  When back to free-flowing, apply.

    If in doubt, water it in.

    I agree - if the granules are free-flowing it'll be fine.
    If the production date was 2020 there should be an expiry date somewhere too.
    But if it was only manufactured 2 less than 2 years ago it's fine.

    Not sure there's much point in using it at this time of year though - like other plants, grass is shutting down for the winter.

    Out of interest, what is it?  Slow-release? N:P:K % ? Any weed or moss killing ability?

    In Surrey, my grass never shuts down for the winter.  Slow-release fertiliser (I use Scotts) or an organic based one are good at this time of the year. A fertiliser with a  high level of soluble nitrogen would not be a good idea.
