Dry weather, cold weather, and hot weather can all prevent Black Spot. You have black spot whenever you have these four conditions at the same time: 1) susceptible rose variety 2) wet leaves for six hours 3) temperatures between roughly 60 degrees to 85 degrees 4) black spot spores on the leaves In theory, one could prevent black spot by 1) washing the spores off the leaves 2) drying the leaves before the spores germinate 3) putting a canopy over the leaves to prevent them from getting wet when it rains Here is a link that might be useful: Black Spot of Rose

Cathy, I just stumbled across your cage master plan. Note that none of the 3 message titles about this would lead the casual forum reader to know about the project, and there are far more casual readers than posters! Rather than losing the project and your considerable efforts to the forum ether, let's put it in the FAQ along with the other cage. I have copied your text instructions. I think we should wait until the cage is complete, screened, and populated with plants rather than show the bare frame as the only image. Other people will be unlikely to duplicate it precisely; it is the general appearance and major construction tips that count. The FAQ is around year after year, the timing of the project is not critical for this year only. Please use "butterfly cage" as part of any future message titles so that I and others will be alert to its progress.

Wow! Great photos! I'm jealous that you have butterfly bushes blooming already. I have buds forming on mine but no flowers yet.

1. Stripping it before it is completely dry would be fairly easy. So time if of the essence in making a decision. 2. He certainly could have taken the first strip off at any point though the strip would have been ruined. It sounds to me like you had an extra roll though so what was the problem? 3. The paper was improperly installed regardless of the brown. It is mismatched. That is unacceptable. Period. 4. The guy knew he was going to be hanging something vintage. If he was not familiar with vintage paper, he should have done a little research before he started hanging. When you know you are working with an unusual and expensive product, you make darned sure you know what you are doing before you start because that material comes out of your pocket if you screw it up. 5. YOU don't strip the improperly hung paper. The paper hangar comes and does it for you at no charge. 6. The procedure described by Annie, overlapping and then double cutting, was the proper solution. So if you have another roll, why not try it? Are there any scraps around that would allow the guy to do some practicing before he has to work on the new installation? 7. I tell my clients to accept nothing less than total satisfaction from their contractors. Paper hangars are well compensated for their SKILLS. On an easy job, I can find myself clearing $70 an hour, tax free. When something like this happens, I take a loss but it's my own fault. Even with the occasional loss, my average hourly income is still ample compensation for what I do. There is no reason for you to feel bad about requiring the guy to make you whole. I can't tell you how many jobs I've done, where the client paid me to strip and rehang a job they had paid another hangar to do! They take a total loss on the original labor and materials, and the cost of having me strip, because they don't want to hurt the hangar's feelings. And as crazy as that is, I have to say that I have done the same thing with contractors! 8. Covering the seams with trim is an option. It will look like you papered over paneling. It's the mobile home look, lol. And if you get your hangar to reimburse you the $400, you may be able to use that money to do something else nice for your kitchen. It's something to consider. I wish you luck with finding an inexpensive solution. Please keep us informed!
