Mildew is fairly easy to get rid of as any rose fungicide will solve the problem. Just follow the directions on the package.

I have three habiscus shrubs that appear to have white flies and lots of cloudy white webs. I have sprayed every two weeks 3 times with malathion but it doesn't appear to be working effectively. Any suggestions?

The only thing I've found that works for white flies is horticultural spray, ck at your garden center.
The webs might be spiders coming for the flies. It's a bit early for spider mites.
And spray EVERYTHING in your yard for the flies, they are will live on anything with leaves.
Good luck

Remove effected parts of the bush, leaves, stems, buds.
You can leave it there, or you can spray a fungicide from the garden center.
I prefer the ones which are absorbed by the bush. If mildew an ongoing problem, and you choose to spray..start early as the bushes are leafing out, and repeat as directed on package.
There are also powders, but they wash off and are toxic to birds and bees.

Also known as Black mildew, Peronospara sparsa.


Remove infected leaves (either on the plant or on the soil or mulch below it).


Remove leaves from the lower nine inches or so of the plant (even ones that are not infected). When watering, try to avoid splashing water back up onto the undersides of the leaves.


There are a number of treatments that can be sprayed onto the plant, ranging from the relatively benign Cornell baking soda/horticultural oil/water mixture to stronger products, including Daconil and lime-sulfur. Keep in mind when doing so to spray both sides of the leaf surfaces, especially the undersides.


An ounce of prevention is worth a pound of cure. Good air circulation is a must. When the leaves get wet, you want them to dry off. If your roses are planted too closely together, the foliage towards the inside of the clump will show signs of blackspot first. Pruning that area in such a way that air can better circulate will help reduce an infestation.
