Allotments 4 All

I am in the throes of taking on a new allotment and find that it is covered with thistles and couch.  There is a shed and on opening it I have found a can of roundupl so Iam not certain of its age.    Does it  go off, of will I need to buy some more?   John Verney

Hi John.Found you again! Someone will I am sure be able to help you.Does it not have a date on?I wouldn't have thought it would go off.Or could you email the manufacturers and ask them?

As said - but doubt it, if undiluted. V expensive, so if there's a good bit, try it and you'll soon see? Better than paying to dispose of it?? = Tim
