Question From: Seal Beach, California, United States
Q: My potted geranium has white spots on leaves and flowers petals.
White spots that look like powder would be powdery mildew. White spots that are fuzzy would be mealy bugs. Powdery mildew is a fungus and is treated with a fungicide. Serenade is an environmentally friendly biological - bacillus subtilis that helps to control the problem. Water at soil level and do no overwater. If the problem is mealy bugs, AzaMax is an OMRI listed product that is also environmentally and safe to use around animals and folks. Best And Happy Yardening, Nancy.
