West Sussex, United Kingdom
I'm sorry to put in another question so soon but I visited friends yesterday who have both been very ill for a few months. Now they are surfacing and taking an interest in the garden again. About 3 years ago they bought a number of bush roses such as Gertrude Jekyll, Gordon Thomas and Arthur Bell etc. but these have been sorely neglected , unpruned, mossy and with blackspot. I know it is too late to prune but should I use roseclear and Epsom salts first? Or manure? Or Toprose? What is the best plan of action please?
