Hello I have moved into a new house with a large established Laurel hedge. I have pretty much zero experience of gardening, so want to seek some advice on managing the hedge. Ive learned a lot over the past 12 months but I'm at a stage where advice would be welcome! So far.. the hedge had a powdery mildew issue, and I have been treating this through the year with fungicide. The situation has improved and Im monitoring the situation into this years growing season where I hope the issue will be resolved. I have also trimmed the hedge back to shape and control it. One end has been pruned more than the rest as it was quite wild, the pics will show what I mean. The area Im seeking advice on is this... do I need to be pruning the branches to thin it out? The bush looks quite tightly packed to me and I know this wont help with powdery mildew. I also think by thinning out the branches this may help the appearance of the leaves.. Ill attach some photos, any help and advice is most welcome!
