Hi Tony ,

Thank for your answers,
I know also English Walnut affect with juglone other plants , I made many searches in several languages , I was thinking that in the several British Hedgerows experiences may find some advice !
I was also using the black walnut information but so I find only American species,anyway may be useful !

I will try again as I don't like to fell this tree ,

Whoa, on second glance, I see you describe it as a Juglans Regia
(English Walnut). I'm not aware of any problem with other plants and
English Walnut, but I'm not sure it doesen't have toxic qualities to
other plants. Again, a good search should give you the answers.
