Well done it looks beautiful the name suits it, I can see you are getting addicted like the rest of us rose lovers
Jan.

Very nice Marion great name as Jan said it does suit it.
And beautiful pics too, did you try that milk spray for the problem
If not then get some Triforine that will fix up the Powdery Mildew.
Cheers..MM.

It is well named isn't it ?

Yes Misty, I have used the Triforine and the milk and water.
It seems that you use full cream milk and I have been using Trim so maybe that is why it is not working as well.
The Double Delight is the main trouble and it has nearly been deleafed by me, poor thing.

How many times do you spray the milk between the Triforine sprays.
I am very careful not to wet the roses when I water.

Don't want to rain on anyone's parade, but Triforine is not for PM. It is good only for Rust and Blackspot as a preventitive. Get some good advice for PM. specifically.

Lozza, I half agree with you. I find triforine less effective on mildew than it is on black spot, but the product IS officially supposed to work on mildew.

A good pest oil spray will wipe out mildew on a plant. So will lime suplhur at this time of year. I used pest oil to great effect in the last season, where a bush was 'getting away' on me. The new Rose Shield from Yates seems to work all right too - its active ingredient is myclobutanil, not triforine.

Well, thanks a bunch Daniel. I stand corrected.

If mildew is your only problem Ashmeri then my advice would be to deliberately wet the leaves of your roses. While humidity is conducive to mildew infection, free water will cure(depending how long you wet them) and deter mildew.
We grow potted roses both under polythene tunnel houses with drip irrigation and outdoors under overhead watering.The plants under overhead watering don't suffer from mildew while the ones under poly just get hammered by it(without any intervention).Conversely the indoor plants never suffer black spot while the outdoor plants can do depending on time of year.
If you actually do grow your roses under eaves/against walls etc as your photo might suggest, then you may likely find they rarely develop BS while mildew becomes a pain in the butt.Like our roses under poly they may experience humid air conditions over night but upon close inspection in the mornings their foliage is far drier than the roses located out in the field/garden etc.This is ideal for mildew.
If you are in fact growing your roses under eaves and wish to leave them there, then I too would choose oil sprays (plus bicarb) over triforine as the latter product is an expensive waste of time under mildew conducive conditions.Since like us you live in a hot climate then I would suggest using pest oil at no greater than 2ml/L H2O (plus wetting agent and about 1 level tsp/bicarb/L H2O) to avoid burning.Higher rates are no more effective and will quickly burn leaves etc.You may have to re-apply at close intervals and thorough coverage is essential to optimise results.Despite this even oil/bicarb sprays are far from perfect and I would suggest you choose varieties carefully and eventually eliminate poorer performers.
Overall we have found that you can grow BS resistant varieties(egDuchess de Brabant) well under dewy,rainy or overhead watering conditions outdoors and you can grow mildew resistant varieties(eg Rainbows End) under a raincover and enjoy lengthy disease free periods by doing so. Hope this helps.
