Flowers need hormones, and most of them can't be secreted without light. You can try to lengthen or shorten the light appropriately. If cyclamen is placed where it can be photographed at night, move it to a place where it can't be photographed at night; If you put it in a place where you can't get light at night, try to put it in a place where you can get light. At this time, you can clean it with a heating lamp or an incandescent lamp. \ r \ n \ r \ I hope to adopt it.
