Questions

I planted this evergreen clematis last year, it was doing well but I noticed some starting dying off in the last few months. See the attached pictures. It is planted against a screen about 2 metres from an established silver birch. Is there anything I can do to save it?

I have healty looking roses, I prune & feed but they won't flower, I get 1-2 flowers per year plant! they are planted now 3 years. please help, how can I get them to flower!
