Janet Pizaro on Jun 24, 2016The photo is not very clear,however it seems you have more than one issue going on. You may have a fungus which is created by improper watering. Second if that is the case ,insects then arrive. Try using a two in one systemic control on the roses by Bayer. This will hopefully get rid of the insects and fungus and promote new growth.Helpful Reply

Jessica on Jun 24, 2016I agree with the above. Also check your drainage. If it is poor, the roses will have wet feet & be unhappy.Helpful Reply

Colleen Walpert on Jun 24, 2016I would try spraying with Neem oil first. It is a natural fungicide and insecticide. Also, as mentioned above, check the drainage and be sure they are planted in an area that gets at least 6 hours of sunlight per day. Trim off and burn or destroy the browned out leaves. They will not rejuvenate and letting them drop to the soil will spread the fungus.Helpful Reply

Rachel on Jun 24, 2016If it's insects, I mix a little dish washing detergent with water and spray the entire plant. Bugs suffocate and die. Just shower off...the plant.Helpful Reply

Diane on Jun 24, 2016I am unable to use the Neem oil on my Lg collection of miniature roses because it gets to hot and they burn but mixing A tsp. of dawn dish soap to 32oz water works great whether its fungus or white fly's.Helpful Reply

Carrie Davis on Jun 24, 2016It really looks like you have powdery mildew on your plants. It is caused by excess standing water and high humity. It is recommended that plants are spaced apart so they don't stay wet and make sure they get enough sun everyday. You need to get a fungicidal spray your plants in the morning once a week until all signs of the mildew is no longer visible. Spray in the morning so the plants dry to avoid burning the leaves in the heat of the day. Homemade remedies are recommended, saying they are not as effective. You need to treat as soon as possible to avoid losing your plant. If in doubt, place an infected leaf in plastic bag and take it to a local nursery. They should be able to give you the best answer.Helpful Reply

Gmk7499166 on Jun 25, 2016Roses like pkenty water from the groud only , don't water the leaves, bush. But also they do not like soggy roots .they need good drainage. If they sit in water it will promont fungus growth and root rot.Helpful Reply

Jean Moore on Jun 25, 2016Also, roses like good air circulation. Try not to plant them around other spreading plants. Water at the base of the rose bush and try not to splash on the leaves. At some point it seems all roses experience black spot. Then you're supposed to remove affected leaves and dispose of them so as not to spread that disease. In my experience black spot doesn't kill the rose but it is unsightly.Helpful Reply
