Blackspot is not airborne to any significant extent. It carries over mainly within the bark of canes and to a lesser extent in fallen leaves (Compendium of Rose Diseases). Landscape cloth would have no effect on disease, but I think every experienced gardener here would say it is useless and troublesome in the long run. Mulch rots on top and the resulting soil supports weed growth.
'Carefree Beauty' is BS-resistant in many gardens, but apparently you have a race of BS that affects it. Frankly, your choices are to live with it, try a different variety of rose, or spray fungicide every two or three weeks.
A little more information might help. What do you use to spray for BS? How often? Do you use Bayer Garden Disease Control for Roses, Flowers, and Shrubs (and I mean that exact name--not one of the other Bayer products)?
Are you sure you are not looking at old blackspots which were killed by a previous spray? The spots will not disappear even though you have destroyed the fungus called blackspot. However, the new leaves should come in with no spots on them.
Do you have this problem all growing season? Or just at certain times--maybe spring and fall?

I also have both, and I can't say that either of them have any fragrance to speak of to my nose. I'd give Fire 'n' Ice the edge for having a somewhat lighter reverse than Love, but it's much less hardy in my zone. I've had my original Love for 5-6 years, and replaced Fire 'n' Ice several times, only lasting a maximum of 2-3 years each. It might be one of those roses that isn't good on its own roots, since it's a dinky little plant - or maybe it's just a miniflora, as Seil says. I agree with her that neither is a frequent or prolific rebloomer.

I really like my Sonia and I got it own root from Roses Unlimited. It has grown well so far, as typical of their roses, and even snuck in a bloom on me before I could get it disbudded (I nip off buds in the first year to help build more structure to survive the winters). It has grown nicely bushy and we'll see if it's as tall as predicted, but I have been pleased with its vigor and general avoidance of most blackspot. It's in my "hot" bed of HT/floris, so as far as I'm concerned, the more color the better. So far it doesn't seem to fade like some of the apricot/orange roses can do, and given that it's near Tropicana, Fragrant Cloud, and Oranges and Lemons, it's welcome to put out blooms that are as garish as it pleases.
BTW, the way to interpret Roses Unlimited website is that they list all the roses for which they have mother plants and are propagating for sale. You're right that you can't tell from this listing which of the roses are currently available, though the vast majority of them are, but Pat responds quite promptly to emails asking about particular roses, and she's very generous with suggestions for roses that might suit you if you ask.
Below is the one bloom I let it get away with this year.

Our housing doesn't have a compost heap either, and I believe it is for aesthetic purposes. Yah whatever. We have a community plot but can't have a compost heap. They keep things neat and tidy here and that is a plus but there is a limit. And those black plastic things or whatever similar man made unit just don't work that great.
I had to trench compost my kitchen waste in my plot. Dig a trench, put in the smelly ripe kitchen waste and bury it. Tamp 'er down good. Now that the tomatoes have taken over I can't move in there anymore and so cannot dig anymore trenches :o)
I have a container on the counter just for coffee grounds and banana peels. The peels get cut width-wise into ribbons and mixed in with the coffee grounds. Shaken, not stirred. When the bucket is full the roses get a little snack.
My MW was dark colored from the beginning.
MW perks up as it gets more mature. I occasionally need to prop up a bloom if we have a hard rain, and its "neck" does seem to have a slight but graceful bend to it, but otherwise the flowers are reasonably pickable.
Munstead Wood--first blooms (last year).

Hi bonsaimaster. I love your passion. Never give up in your quest to find a rose you really want. Our whole Save the Roses! Auction is geared toward preserving the genetics of roses that might otherwise be lost forever. This year we will be offering Ralph Moore's last floribunda, which is in the process of being registered as The Final Bow.
Anyway, I have Osiria in my yard and have to agree that it is a most difficult rose to grow. However, I will try a rooter pot and see if I can get one going for you. Keep your fingers crossed.

so, another newbie question...
I am planting the climbing roses on either side of an arbor which is flanked on both sizes by a picket fence. I would like to train half the canes up the arbor and the other half along the fence. Is that a reasonable expectation?
And how far away from the corner of the fence/Arbor should the climbers be planted?
I am going to try to post a photo...
I agree with mad_gallica...
Bone meal isn't water soluble, so there is no reason to add it to a "tea". Also, what type of soil so you have (sand, clay, silt)? Water solubles drain quickly through sand.
