I moved house in December and inherited a massive garden which is totally overgrown. Now we have done quite a bit of work already and in doing this I found 2 potted azaleas. They did come out in flower but it was rather sparse. So I thought I would give them a trim now to help them. They are very woody and there is not a lot of leaves on them either. If someone could tell me the best way to trim them back so I can get a decent flowering, I would appreciate it.
I hope this information is what you need: https://www.gardeningknowhow.com/ornamental/shrubs/azalea/pruning-azaleas.htm
Don't know if you're already familiar with the Master Gardener program (I'm guessing you're in the UK,) but if you don't know about them, they could be really helpful for you.
