The leaves on my African violet have suddenly wilted and turned a grayish color. The plant bloomed really well in late winter for a few weeks. It is in an east window and I haven’t changed the way I have been watering it. Any ideas?

If the center leaves are wilting, it could be crown rot. Try not to get the crown (center) wet when watering. If the outer leaves are the ones giving you the problem, it could be due to the cooler temperatures during winter. Plants will not need as much water when cold. If you have not changed your watering patterns, you could be overwatering.
