How do i keep my roses healthy ?
I have a large yellow climbing rose on my house (probably 20 years old) for the past 5 years it has developed very bad black spot. I spray very regularly but it still takes over. Each year if is covered with beatiful yellow flowers but by early June the black spot take over and it looks terrible.
Is the situation recoverable ?
I have come to the conclusion it is not and that i should dig it out and replant another. Do I need to dig all the soil out also and replace that ?
