Hi I put a rose arch in my garden a few years ago This year i have had a lot of leaf rust which has spread right over the whole arch. Will the roses recover? I assume best way to treat is to pick up as many dead leaves as possible and make sure base of rose is well mulched. Is the arch too dense? and should i have shaped it better? I have enclosed phots for you to look at. The roses are all David Austin which i thought would be very resistant to disease.
Roses that grow through an arch should not be too vigorous and fast growing. If you know the name of the rose, it will help others to give you more advice.
