Annual problem with diseased lilac July to August
Norfolk, United Kingdom
Every year the leaves at the top 18" of each of the tallest branches go brown and curled and then drop between July until autumn - very unsightly. Has happened every year, bush is mature (approx 9 years) and about 10-12' high. Thought it was windburn but don't think this is the answer.
