What ever you do, do not be so quick to do so. I had rhododendrons for all of my adult life. They are acid loving plants. A soil acidifier would help. For years I used Mir-Acid fertilizer. Once in early May, once in mid June, and again in early August.
The other critical thing that you need to do is to "deadhead" the plant. You have to remove as many of the old flowers as you can. If you don't, they will produce seeds and produce fewer buds.
Be careful removing the old flowers because the new growths or branches arise from the same place.
If your soil is not acidic enough, they won't bloom as well. They like the soil 5.2 to 5.8. The beauty of a Rhododendron is not in a perfect shape, the beauty lies in the number of flowers produced. You correct the soil acidity, deadhead the old blooms and I guarantee it will fill out and bloom like crazy!!!! 😜

Thanks Big Bill, did add some pellets around the base for acid loving plants and currently giving a liquid feed once a fortnight. Will remove old flowers as advised by you, does that include any buds that do not open?

Yes.
If you do not dead head, you may see one or two new branches develop. By deadheading you may get, three, or four new branches develop. Each new branch tip is a potential bloomer. It is a classic geometric progression.
If your little guy produces a hundred branch tips and 20% bloom, that is only 20 flowers. But if you get 250 branch tips and 20% bloom that is 40 flowers. You carry that forward a few years and you'll be swimming in flowers!! Good luck!!!

Some sun prevents them from getting leggy and trying to reach for the sun. Pinching can also help fill certain areas of the bush. However, the plant on the picture still has unopened flower buds so wait until blooming has completely ended.

Will do Luis, thanks for your advice. We are getting quite a bit of sun at the moment which is not the norm in rainy Manchester UK. Smiling
