Can enyone tell me how to remove black spots on roses?
Are your roses in an area that gets good ventilation or a cross wind?This allows the surface of the leaves to dry more quickly after rainfall or watering. Moisture on the leaves is what causes the development of black spots, it is a fungus.


So do not overhead water. Also, water is the what allows the black spot spores to spread so splashing water only multiplies the problem.


Remove all areas of the roses that are diseased and rake up the leaves , (do not put this in a compost pile). This reduces the chances for future infections. Finally spray with a baking soda spray:


1 tablespoon of baking soda


2 ½ teaspoons of summer oil, a natural oil based and mix


with


1 gallon of water and spray on the leaves.
Reply:That is a fungus that grows on them. Go to your local DIY center and pick up a product thats called the Ortho Rose Pride system it has everything you will need to rid them of those nasty black spots.
Reply:you need to spray them with a rose spray for bugs, fungi, black spot etc.
Reply:Black spot is a fungus disease that appears as round, black spots on the leaves of rose plants. There may be a distinctive yellow band around the black spot and leaves may fall prematurely. Left untreated, black spot may infect young canes.





Look for black spot on the leaves of rose plants. This fungus disease will appear as round, black spots ringed by yellow tissue.


Water roses only from below. Try not to get the foliage wet when you water.


Water in the early morning hours so the rose plant has time to dry during the day.


Rake up any fallen leaves from the soil surrounding the plant. Black spot as well as other fungus diseases are transmitted by water splashing back up onto the leaves and stems. Remove any diseased leaves. Pick off and destroy any foliage that has evidence of black spot. Dispose of infected foliage in a sealed plastic bag.


Dust roses infected with black spot with sulfur powder. Sulfur will not kill the fungus spores, but it will prevent a new generation from germinating.


Spray a solution of 1 tsp. baking soda mixed in 1 qt. warm water in the early morning hours.


Spray roses with a dormant oil or Bordeaux mixture when plants are dormant (usually in winter).
Reply:You won't be able to remove the black spots once they are there but there are many sprays on the market you can purchase and apply to prevent the black spots from appearing. A regular spraying is needed for roses prone for this disease. Also clean up any leaves which drop that have the black spot as this is another good preventive and help stop the spread of the disease. Check the sprays for rose care as there are many brands. Roses need lots of water, feedings, and sprayings to remain healthy plants. Good luck.
