Removing rose mildew
Powdery mildew is one of the most common problems with roses. Powdery mildew first affects the leaves and then spreads to the buds and stems. The good part is that powdery mildew cannot kill the roses, only that will destroy the flowers.
Some of the materials that you will need are:
- Baking soda
- Dish detergent
- Cooking oil
- 1-quart spray container
The first thing that you need to do is inspect the rose. Check the foliage of the roses and also the blooms.
If you find some evidence of mildew, then you should prune those areas. This will prevent it from spreading. If the infection is small, then you can get rid of it easily, by removing the affected leaves, or by using simple water to wash it away.
Home made solution
If the infection is a little more serious that you have expected, then you should try an effective home remedy. You will need to mix a gallon of water it a quarter of a cup of white vinegar, one table spoon or baking powder, cooking oil and dish detergent. Mix all these ingredients well together.
Pour the solution in a spray container and then drench the bushes with it to kill all traces of mildew.
