Leylandii

[sammy46]

Hi

I have an Leylandii trees all around the school were I exercise my horse, when showjumping or dressage. Recently she has developed an allergy of coughing, itching and hedshaking and I think it is the Leylandii which is causing the allergy, have you every heard of this before? or do you have any information about Leylandii that would help. Many thanks, Sam
