My garden ponds needed a new liner, and our horse chestnut tree had leaf miner. Crossings Tree and Landscapes, recently working in Camberwell Grove, seemed knowledgable and confident and had a professional looking van. Unfortunately they left both ponds leaking, and said the used "Murphy Mortegg" on the tree - which I see from the internet has been illegal since 2004. Looking at the tree, I see no evidence it has been sprayed. They said they would come back to do repair, but repeated phone calls to 020 8485 7232, and to 07733 270 216, have resulted in no reply and on one occasions I heard breathing at the other end ! Their address, "Bridge End Farm, Dartford" had no postcode. Over ?3000 down the pan !
