Gerry, we have an evergreen hedge with small leaves. Currently two thirds of the hedge is looking very bare and the leaves that remain on it have brown spots on. In the centre of these brown spots are white spots. The entitre spots are 5mm across and there are as many as 20 on each 2cm leaf? Advice please on how to save the hedge!!!!
With any of these hedge diseases, there is no control, but to let the hedge take its chances. Sprays are not very effective and you cannot be spraying every few weeks.
