Advice on black spot on my climbing rose please.
Every thing was wonderful until this hot weather arrived. I have read all the books, browsed through the internet but still can't find out why my rose suffers so. Is the disease actually in the soil and was already present when i purchased the rose? I clean up all the fallen leaves, i spray with a fungicide regularly but still it attacks every year! Should i just dig it up and buy a more resistant rose? It grows against a S/W facing wall, could this be the problem?
