Generally, carnation is planted at the end of August. Prepare basin soil, apply enough basal fertilizer, and 5-6 seeds per basin (avoid not sprouting). After sowing, when one or two leaves are grown, the seedlings shall be thinned. When 3-4 leaves grow out, they can be transplanted.
When transplanting, the spacing of each plant is about 5, and each pot has 3 plants. Water after planting.
The most suitable temperature for the growth of carnation is 15-20 ℃. When the temperature is high in summer, it should be properly shaded and cooled. In winter, it should be placed in the greenhouse, and the temperature should be kept above 12 ℃.
During the growth period, the flowerpot should be kept in a sunny outdoor environment. In summer, the scattering light is the main way to avoid thunder exposure. When the temperature is high, shade and cool down properly.
The principle of no drying and no watering shall be mastered in watering. For the bamboo planted in autumn, attention shall be paid to antifreeze when watering from November to December. Indoor maintenance shall be carried out. The water temperature shall be close to the room temperature. When the temperature is high at noon, there shall be no water on the leaves at night. In the next spring, it is required to irrigate the green water, which is the same as that in winter.
During the whole growing period, the top dressing was 2-3 times, and the rotten cake fertilizer or organic fertilizer was used.
If you want carnation to bloom more, you need to prune it in time. At the height of the plant, the heart is removed, the branches are promoted, the buds are removed in time, and the loss of nutrients is reduced. The cut carnations will bloom again.
Keep the light for 6-8 hours every day. In midsummer, the carnation is in a semi dormancy state, so we should pay attention to avoid the sun exposure. The basin soil should not accumulate water, otherwise it will rot easily.
There are not many diseases and insect pests of carnation. The common diseases are calyx rot, rust, grey mould, bud rot and root rot. In case of any disease, the sick plant shall be cleaned up in time and the medicine shall be sprayed for prevention and control. It is not allowed to neglect.
