Older rhododendron problem
We inherited a very old scraggly large rhododendron. It was never in very good shape and we have done a lot to try to improve its health: extra water during dry summers, added iron and added epsom salts, special rhodo fertilizer. All to little avail. Some photos of the poor quality lime green leafs and spotting can be found here:
Any assistance on whether we can do anything further to help this plant would be appreciated.
