#26 Ippy, I’ve been in my house about the same time and I’m still to really tackle my garden properly. Next year...maybe...
I love roses, I used to grow a lot of medieval varieties and then the David Austin roses that repeat flower. Gorgeous things. There’s a really nice little climbing rose called Goldfinch that is brilliant over an arch.
Rhi, try 'The New Dawn', last time I checked it was the only recurrent flowering rambler available, it's predominately white with a feint pinkish hue to it, keep all of the greenery trim to allow the air to blow freely around all of its parts and it should remain mildew free too.
If you live in a big town mildew is less trouble than if you live in a rural area, pollution keeps the mildew at bay.
I don't know how you are with environmental issues, you'll need to read the label, but there is a rose spray that is the most effective available that I know of, it even clears out rose rust, it's called 'Rose Clear', if you do use it there's no need for any other, it's systemic the whole of the plant becomes poisonous to all of the usual pests, any over spray gets taken up by the roots, expensive but it 100% works. (I just need to see where my shares in 'Rose Clear' are at the mo), oh yes, it doesn't taste that good.
November is the best time to plant, March is reasonable too, the tubs are ok all year, that Fragrant Cloud rose I have planted is the most fragrant you can get, so they say, it's also related to Peace, almost any rose with Peace as an ancestor is usually very healthy.
You've started me off in one of my favourite interests so it's your own fault if it looks like I've been going on about roses, so there!
Kind regards ippy.
