What can you fight powdery mildew?

Thoroughly remove infected parts of the plant. They do not belong in the compost but should be disposed of in the garbage so that the mildew cannot spread to other plants. In the case of a heavy mildew infestation, it is best to remove the entire plant. There should be no phlox in this place for a while. It is better to choose a new location for your replacement plants.

Healthy plants are less susceptible to diseases and pests. That's why it helps best if you take good care of your phlox. Make sure the soil doesn't dry out too much. They achieve this not only with regular watering but also with mulching. Do not fertilize your phlox with too much nitrogen, otherwise its resistance will also suffer.
