I have a Nancy Evans rhododendron in a large pot. This month the plant has started dropping leaves from the lower parts of its branches, the terminal leaves and flower buds look perfectly healthy. The affected leaves turn solid bright yellow and eventually drop. I have tried Epsom salts, seaweed tonic and the plant is looked after in relation to feeding and watering.
Has anyone any advice please?
