A couple of rose questions
1. I bought a couple of shrub roses ,
Tuscany Superb and Queen of Denmark. could they cope with a site that only gets sun in the afternoon? They would get more in the winter when the leaves are off the trees. The RHS wasn't very helpful. Says full sun, but also NSE or W aspect. North wouldn't get full sun.
2. I have R. moyesii which has always had a tendency to yellow leaves. It's been there some years and has had applications of horse muck and occasional chicken pellet manure. In the same area, this spring, I planted R spinosissima which was a lovely dark green when I put it there but is now more yellow. If it was a deficiency what might it be. Or, as my garden is a former tip used by builders and farmers, if there was something in the soil there what sort of thing might cause yellowing
