What’s wrong with my rhododendron?
I have a rhododendron in my front garden which is mostly driveway with a wide border that links to my neighbour’s that has a line of conifer trees separating them. The rhododendron is next to a tree (see pic I’m not sure what it is) and a little further away a hydrangea that is perfectly fine. The rhododendron never flowers. It has the odd bud on it. The leaves are yellow, mottled with spots and curled. The plant has very little foliage on it. You can see from the pics where I cut it back a couple of years ago and the leaves look greener but it is clearly still struggling
