J. Noe, Bromley
All staff were very efficient and a pleasure to deal with. Rob was most helpful in his advice for what I wanted done. I
am really pleased with all of the work that was carried out. Three trees lopped, and general garden feed sprayed throughout the garden. That has made a difference with all my perennials which are looking amazing now. The Laurels are looking so much better after the spray that was used to treat the fungal decease. Am delighted with all the work that was carried out. Thank you very much.

Robert Cosgrove was most helpful and knowledgeable when he first visited the site which involved about seven aging trees, three of which had to be felled, one a lovely horse Chestnut hopefully to be preserved by Bartlett's treatment of the soil around its roots. He clearly loves trees and wants them preserved. After his application to Lewisham Council, he gave helpful advice as to how best meet their conditions and as to the five replacement trees to be planted and as to where they should go. A good professional doing a great job. All the crew members on site were very good, helpful, and polite to a number of concerned Local Residents who came out to speak to them.
