had aphids which I dealt with (sprayed soapy detergent on them) then roses developed black spot (have sprayed) but all the leaves have fallen off and they look barren and horrible! Only young plants. What can I do?

I know it is disappointing when something like this happens. Your roses have been established now for 10 months so they would have established a reasonable root system by now. Even if they have lost their leaves, it doesn't mean that the plant won't survive. Roses are very hardy plants which can withstand harsh conditions, attack from pests and disease and yet are still able to bounce back. At this stage the best thing you can do is to improve the health of the plant by giving it regular applications of Yates Dynamic Lifter Liquid Concentrate. It's an organically certified fertiliser, which contains seaweed, blood&bone and fish meal to help developing new roots and restoring healthy growth. Apply the product every 2 weeks to bring your roses back to good health. It wont be long before you will be giving your roses their winter prune. It is too early at this stage. You can however give them a light prune to remove any dieback that may be present. Top up the mulch around the root system of the plants. Keep the soil moist and just nurse them along. I am confident they will recover.
