Weedkiller

Q: Ken, I enjoy listening to both of your shows and find the information useful in our garden and on our allotment.  Sadly I only caught a snatch of last Saturdays show when you were discussing a chemical treatment for horsetail.  We are plagued with this hardy weed on our allotment.  Could you give me the name of the treatment and where it can be obtained.  Thanks, Robert

A: The product has rather a long name, it is SuperFastLonglastingWeedkiller.  It’s from Neudiff and is sold through the english company Doff.   Should be available from good garden centres.
