Rhododendron leaf spotting.....what do you make of this please, and should I be concerned? This is Rhododendron 'Mindy's Love' which flowered beautifully this year and looked very healthy. Now this.....it's leaves are droopy and there is very little sign of any new growth, just a couple of small buds forming. The whole plant is affected with spots on all the leaves.
