I would like to know how I grow African Violets in cold weather?
Where to put the plant and any specific care they need
As the name suggests, African violets like warm indoor air. Do not put them where it is chilly such as a window sill. They scorch if given a lot of direct sunlight from south-facing windows, particularly during summer.
