Thanks for the reply. I'll attatch a before and after photo below. We were convinced that we didnt take too much off...

Hi all, Looking for a bit of advice from someone a bit more knowledgeable and experienced than myself. The weekend before last we reduced a row of leylandii that hadn't been trimmed for about 4 years, we reduced the top back to where it had been done before (by approximately 5ft) and then trimmed the sides with a hedge trimmer. The customers were very happy with the results and the fact we hadn't reduced it too hard or butchered it. Fast forward to now (8 days later) we received a call to say a lot of brown patches had developed, so we went out to have a look, take some photos and try figure out what had caused them. We've been scratching our heads trying to work out what could have caused this and the only thing we have come up with so far is the very hot, dry and sunny weather we had the week following us reducing it, and we thing it could have been sun scorched? I'll attach some photos below (the first two being just after we had finished and the last 3 a week later), we would really appreciate some advice if anyone has any...
