Answer 2

My roses gets this, too, and I can't get rid of it because of the climate we have here. I do take all the infected leaves off of it and discard them. Never put them in your compost pile or leave them on the ground. It'll infect the other plants. You can try Neem oil spray, or Baking Soda spray. Here is the recipe for Baking Soda spray;
4 tsp Baking Soda
1 tbsp Horticultural Oil
Per gallon of water.
Mix them and spray every 5 to 10 days, only in the early morning, or after heavy rains.

You must eliminate all the spotted leaves first. Good luck!
P.S. I don't believe that the roses are cactus family... :( You can't over water roses. They are big water drinker and they are not drought tolerant.

Cut off all affected parts and burn, sterilize snippers. Bury cornmeal all around the base of the plants before they start to grow again in the spring. Keep burying cornmeal around the rose once a month or so. Also bury your banana peels under your roses, I cant remember why, but it is great for them. Oh, and roses are a member of the cactus family, so DONT overwater and DONT get water on the leaves. Trickle water for about an hour early in the day so they are not wet all night. Thats all I have for you. Good luck

Blackspot is a fungus that thrives when humid and rainy. The fungal spores spread in air, from contact from infected leaves and water running down plant. Very common in roses. 3 stages of care. Remove and dispose of all infected stems, leaves including buds that are deadheaded through the season. Do not throw deadhead flowers on ground (I have a bad habit of this when I am just walking by and notice a flower done blooming and pluck it off and throw it down) that's when it gets in the soil, then in the wood.Spraying weakly with Benomyl or Daconil ,READ DIRECTIONS. The fungus can survive through the winter in the soil, so spray roses with a solution of 1 part lime to 9 parts wettable sulfur. If a recurrent problem, prune low in the fall as the spores may be in the wood. TIP-Water at base of plant rather than from above to prevent spreading of fungus. Oh I just remembered, Bordeaux (copper fungicide) is another very effective mixture. You will have to investigate what is at your local nursery. Yikes! it looks like an assignment, blah, blah, blah. Are you gonna grade me? Just kiddin. Good Day!!!!!

Answer 8

You need a fungicide to eliminate the problem. One good solution is to use Neem oil, available at good lawn and garden centers, that come from Neem seeds. You can also use Remedy (by Bonide). It is a chemical that you use in your kitchen for cooking or baking--not harmful but effective.

Either will work. The benefit of the neem oil is it will kill tiny insect pests, like aphids, too. It has no poison, the oil covers the pests and they suffocate.

Answer 9

This is my husband's trick, and our rose bushes are the envy of the neighbors. Boil water and a whole bulb of garlic until fragrant. Strain and put it in a spray bottle. Spray the rose bushes with that mix. He says you're getting aphids.
