1、 Breeding environment

1. Soil. Carnations prefer soft and plump flower soil with strong air permeability and good water retention. It's best to use sandy soil for breeding, not too viscous soil

2. Temperature. At ordinary times, carnations should be given the growth conditions of 19-21 ℃, and the temperature difference between day and night should be controlled within 10 ℃. Take certain measures to keep out the cold in winter. It is best to adjust the temperature to above 9 ℃ and below 35 ℃ in summer

3. Moisture. Carnations are very afraid of ponding, so they must not be watered too much. Don't water too often at ordinary times. Wait until the flowers and soil are dry

4. Sunshine. Carnations like sunshine very much. They can accept full-time sunshine at ordinary times, but they should be properly shaded in summer. In addition, it also needs appropriate shading during its seedling period and full flowering period

2、 Common diseases and insect pests

1. Leaf spot. If there is a disease spot on the stem or leaf, it may be suffering from this disease. This requires us to remove the diseased plants in time, stop watering, and then spray mancozeb or chlorothalonil for treatment

2. Aphids, red spiders, etc. If there are fewer insects on carnation plants, we can get them down by physical methods, and then spray drugs to disinfect and kill the eggs. If there are many insects on the plant, you can remove and destroy the diseased leaves, and then spray Omethoate solution for treatment

3. Gray mold. If carnation flowers, stems or leaves are covered with gray mold like substances, it may be suffering from the disease. This requires us to remove the diseased strains in time, strengthen ventilation and light transmission, and spray chlorothalonil solution for treatment

3、 Breeding method

1. Cutting. Cut healthy and disease-free branches with bony joints about 10cm long, insert them into the soil, then pour them into the water and put them in the shade for about a week. After it grows roots, it can be placed in a place with sunshine for maintenance

2. Sow. This method should be selected in early spring or early autumn. Adjust the temperature to about 20 ℃, and you can plant carnation seeds on the prepared soil. Then cover it with a thin layer of soil, pour some water, slowly maintain it, and wait for it to germinate
