Burying the graft and blackspot canes or canker?

After this horrible winter, I decided the bury the graft on a Wedgwood rose I transplanted. I love this rose! The reason I don't bury the grafts is because we have high canker pressure here, and I don't know what to do about BS'ed canes, either.

After transplanting, Wedgwood showed one cane that got yellow and spotty its whole short length (to the base), which is typical coming out of winter here. So I cut that cane off, and I'm using Bayer fungicide now that she has symptoms. But I know there are a couple of inches of that cane under the soil now. Do I need to be paranoid about disease running rampant at the very base of her, under soil? Because I get paranoid about these things, you see :D

I like that Bayer is systemic, so maybe that will do?

I really have lost roses to disease getting down very low from a cane and spreading (usually on relatively smaller, ownroot roses though), so how is that handled when the base of the rose is under soil? Thanks!

I bury mine and then think nothing more about it ever again. If a cane is brown, I cut it off to where the brown ends. If that is down to the soil-line, then I cut it off at the soil-line. Don't think I've ever even considered peeking below the soil-line to see what was going on. Based on my experience, I'd say you're letting your paranoia get the best of you. : )

Relax and let the rose do its own thing?

I have to agree with Kate. Stop worrying. If the rose is BS prone taking off what's below ground will make no difference. The spores are out there everywhere already. Besides the parts below ground may send you up some brand new basal breaks and that's a good thing!
