Vale of Glamorgan, Wales
I have a lovely double white lilac, which has flowered poorly this last year or two. Last year I noticed one branch had purple lilac flowers on it, so obviously the stock root is taking over from the Graft , which explains its performance. If I cut the root stock growth off as near to the base of the graft as possable, will the white lilac pick up or would I be wasting my time and better to dig it up and replace it.
