Q.Is My Hebe Diseased And How Can I Fix It?
My hebe has got spotting on leaves which I know is a disease tho unsure whether I can use just rose clear on it or a specific type of fungal spray to get rid of that? However the rose stalks are brown and copper like and I am unsure whether these are new buds due to flower or old buds that I need to prune away and I do not know how to do this? It is very much still alive the plant. Please help with advice on how to rectify it.
