1. When topping for the first time, the plant can grow with 8-9 pairs of leaves, leaving only 4-6 pairs of leaves. For the second topping, more than 4 pairs of leaves are selected from the lateral branches, leaving only 3-4 pairs of leaves. Until the whole carnation has 12- 15 lateral branches.

2. When carnations grow flower bones, only the flower bones at the front end of each lateral branch need to be kept, and the others can be removed, so as to ensure the colorful and huge flowers, improve the flowering quality and enhance the ornamental value.

3. After the carnation blooms for the first time, the pedicel should be cut off in time. This will help carnations continue to bloom and reduce the loss of nutrients.

When the carnation flower withers, let it stay in the sun all day, and at the same time, topdressing it once. Because the weather is hot after carnations wither, it is necessary to cool down and ventilate properly. The optimum growth temperature of carnation is 19-2 1 degree.
