We used to buy our weedkillers, sprays, fertilisers etc from a number of outlets in Kent, to maintain our 14 acre garden and grounds. I found Progreen whilst hunting on line for a weedkiller to control an infestation of Marestail. The service has been excellent, with most orders arriving in a day or two. The web site and catalogues are informative and factually accurate. I have never used garden centres for the purchase of sprays as they are usually already diluted with water. Do you really want to buy a gallon of water mixed with a few ml's of concentrate? My only criticism is that you couldn't stop the EU from banning the sale of Curtail.!!!!!! Thank you.
