East Sussex, United Kingdom
Two years ago I bought 10 new roses, planted them in a new flower bed (old roses had blackspot) and for the last couple of years have had a very poor show of roses on only four of the bushes plus a new outbreak of blackspot. The branches are very spindly, thin and long. I am at a loss as to how to improve them. It is good soil with manure added last year. Can a rose person please advise? I have virtually given up on the ones with no flowers but would like to try and save the others.
