I have begun to cut down my Robinia which finally died this year. It was about 25 ft high and began to to look very short of leaf last year ! Any one have any idea what causes a beautiful tree to suddenly expire? ??? ???
This may well be the cause -

This is exactly what happened last year(as detailed in the RHS advice sheet) thanks for your reply ;it has bugged me for some time.
I lost my robinia last year also. It was 14 years old and a lovely tree, I recall we had a drought early in the year and I think that may have been the cause. Have not replaced it in case there is some evil harbouring in the soil.
