Gardening Questions And Answers
Unlike most succulents, many stonecrops are extremely tolerant of cold weather and look great from spring through fall and into winter. Some are hardy in temperatures as low as minus-45 degrees Fahrenheit, even when exposed in pots during the winter. Stonecrops can look fantastic as a single plant in a mixed container.
When a succulent is infected by powdery mildew, it will most likely look like it has been dusted with a classic white or grayish, powdery coating. It usually starts as circular, powdery white spots on the leaves and stems. And as the infection progresses, the spots will turn yellow-brown and eventually black.
