I took out a very old climber and replaced it with a beautiful Falstaff rose which has flowered giving me a gentle scent.
Now all the roses have flowered all the leaves are falling off and are rampant with black spot which I have sprayed consistently.
I was wondering whether it is because I planted it is about the same position as the old rose and maybe the ground is contaminated.
Can anyone throw any light on this.
It is a David Austin Rose.
