Why do carnations sleep after coming into the city?
In 1908, a flower grower from Chicago in the United States went to consult a botanist. He said: "I have many beautiful carnations in the countryside, and they bloom very brightly there, but when they reach the city, they come down with sleeping sickness." The botanist thought it might be because the composition of the air in the city differed somewhat from that in the countryside. To confirm his idea, he took all kinds of gases and put them inside a glass cover, then placed blooming carnations inside, and the result showed that as long as the cover contained a few parts per million of ethylene gas, the blooming carnations would wither.

Pinching and Pruning Methods for Cut-Flower Carnations
1. Pinching Techniques for Cut-Flower Carnations The purpose of pinching cut-flower carnations is to increase the number of branches, raise the flower yield per plant, regulate the flowering period, and ensure a balanced, timely supply of flowers. (1) Pinching time The first pinching of carnations is generally carried out about 30 days after planting, when the main stem of the seedling has 6 to 7 pairs of leaves unfolded. When the main stem has 5 to 6 nodes, the apical growing point is removed; depending on the branching characteristics of different cultivars, 1 to 2 nodes more or fewer may be retained as appropriate, and cultivars that branch poorly may be left with higher nodes.
