The wife decided to start breeding violets. A neighbor gave her a few petioles in the spring, from which strong rosettes formed. Recently, they planted them in separate pots, and after a while we saw these spots on green leaves. I don’t understand what the problem is: this is a disease, or improper care. Who faced similar help advice!
Judging by the photo, there are no signs of the presence of pests, so I can assume that the cause of the ailment of violets in the waterlogging of the land mixture or the plant came to you is not quite healthy, and it could not fully recover from the malaise. Oh, by the way, isn’t a pot with a plant in the draft? Violets categorically dislike them.
