Patio Roses with black spot and dropping leaves.

Help someone please! My roses have been so lovely but over the last few days, black spot has crept in and the leaves are dropping off the plants. I have 6 established plants - all are flowering. I have used spray - Yates, Rose Gun Advanced and followed the instructions but doesn't seem to be helping very much. They are all in wooden boxes and I just topped up the soil. At a loss at the moment :(

And. when I say established plants I mean they are all flowering but 3 of them are quite new and not very big. Thanks.

rain and watering when the weather is warm can do it

I just had to look it up in case my miniatures start showing similar symptoms.

Thanks for your help. Will get on to it tomorrow and hopefully, they will do much better soon.
