I cannot seem to grow Rhododendron. I set the Rhodo’s in Brown Gold. Dug a deep hole and filled it with brown Gold. However even a large Rhode is now starting to turn black – this will spread and kill the entire plant. A smaller Rhode is already ravished and died as per pictures. Thanks Gerry. If you have any solutions. I live on the side of south facing hill. Open to elements. I thought Rhodo’s were hardy.

Rhododendrons mostly need acid soil mixed with some peat.
The plant may have dried out … remove all weeds and grass, water heavily a couple of times and mulch with pine needles or leaf mould in spring.
