These are some leaves from the baby Prospero (given as an end of season bare root bodybag present from my mum about 4 months ago). It was a bit dried out by the time I got it, but it leafed out with great vigour, then promptly mildewed its little heart out.
I already have an older Prospero, and it has never shown any signs of mildew at all , so I assumed it was just because of its bad start...it kept growing, and even tried to flower (snapped them all off, as it had better things to be spending its energy on)
Anyways, the mildew is now cured although the leaves are still showing the effects.
But... now its looking a bit like other roses I had last year that had spider mites.. so what do you think? spider mites, or the after effects of mildew? Or another disease/bug I don't know about?
How hot does it have to be for spider mites to start up? From what I can find, it needs to be hot and dry..its definitely not been dry here, or all that hot yet bar a couple of days here and there..
