What is wrong with my roses?

Question: These rose bushes are Sweet Mademoiselle.  I hope that you can tell me what is happening to my rose bushes and how to fix them.  By the way, we live on the bay, so treatment should be compatible with the Bay. I appreciate your help.

response: Hi,  Could you try to send larger photo files? We can't see what is happening in the photos as the are small and blurry when we zoom in.  Emily

response: Thank you for the new photos; unfortunately they are still small and too low-resolution to allow us to zoom-in for enough detail, but we can make some educated guesses based on typical rose ailments combined with what we can see.  The leaf spotting may be Black Spot, a very common fungal infection that many roses contract in our area. It can be treated with repeat applications of fungicides but be aware that any pesticide (fungicides included) might risk harm to other organisms. Organic options exist but might be less effective, and the environmental impacts of any pesticide can be researched through resources like the National Pesticide Information Center and by searching the active ingredient names online narrowing-down results to Extension and other University content (.edu). Some will biodegrade quite quickly and therefore have limited impacts on the environment; some are also derived from naturally-occurring compounds. Do not substitute a home remedy version as they are not using ingredients tested for plant safety and efficacy. Product label directions should always be followed as this ensures the ingredients are as environmentally safe as is possible. You will notice that many pesticides carry a caution against making applications to open water, but if your plants are set back far enough from a waterside location this is probably a non-issue.  If avoiding pesticides entirely, there are no remedies for fungal disease suppression aside from growing roses in locations with good air circulation (so leaves dry faster after rain or dew wetness and aren't crowded among other plant foliage), full sun (6+ hours of direct light in summer), and using mulch or a living groundcover to reduce the likelihood of spores splashing-up onto foliage from the soil surface during rain or stormy weather. When watering the plants, either avoid wetting the foliage or water early enough in the day so the foliage has time to air-dry by nightfall. Checking roots for watering needs will also help avoid over- or under-watering, which can impact how easily a plant can tolerate an infection or insect feeding. Feel the soil about six inches deep and water well only if it's becoming somewhat dry to the touch at that depth. If damp when probed instead, the plant probably has enough moisture and watering can wait.  The cause of the bud blast (turning brown and dying before opening) could either be fungal (Botrytis, maybe) or due to insect feeding (thrips in that case would be suspect). Cut off blasted buds as no treatment is needed.  More information about rose ailments can be found on our rose diagnostic web page. As a group they are vulnerable to a wide array of problems, but not every rose variety is equally susceptible to all of them. For example, some may have above-average resistance to black spot (none will be perfectly immune) but average vulnerability to powdery mildew. Insect resistance isn't really a trait they are bred for, but few insects bother roses much beyond causing cosmetic damage, and those can be removed by hand when found. Roseslug sawfly, mentioned on that page, is one such chewing insect pest that is currently creating holes in rose foliage this time of year.  Miri
