Got a question? Maybe the garden team can help!
A fellow Gardener asked about white powder on her petunias. Some research
determined that this might be powdery mildew, a fungal infection spread by the wind,
and can also spread from plant to plant.
It will not kill your plants, but will reduce their blooms and disfigure the plants. It can also
spread to other flowers and vegetables.
What to do? Remove any damaged parts of the plant and throw them in the garbage,
not in your compost. Overhead watering will help to wash off the spores. You can also
use a very mild detergent mixture. Be sure your plants are in full sun and have
good air circulation.
Good luck!
