The Culture method of Xiandan Flower

Xiandan flower, also known as Shandan flower, dragon boat flower, dwarf elixir, etc., is an evergreen shrub plant of Rubiaceae, which can blossom all the year round, but it is in full bloom in summer and autumn, with 4 petals, gathering into clusters, delicate and beautiful flowers, drought and high temperature resistance, strong nature, suitable for garden beautification and potted plants, and so on. Let's take a look at the breeding methods of Xiandan flowers.

Growth habits of Xiandan Flower

Xiandan flowers are more suitable for high temperature and sufficient sunshine environment, like humid and hot climate, can not bear low temperature. The suitable temperature for growth is 2332 ℃. When the temperature is lower than 20 ℃, its growth weakens and its flowering decreases obviously, but if the sunshine is sufficient, there are still a certain number of buds. When the temperature was lower than 10 ℃, its physiological activity decreased and its growth was slow. When the temperature is lower than 0 ℃, frost damage will occur. Acid-loving soil, the most suitable soil pH value is 5-5.5. The soil with good drainage and good fertilizer conservation can grow well.

Propagation methods of Xiandan Flower

1. Cuttage: the cuttage propagation of Xiandanhua should be carried out from June to July. The semi-mature branches, 10 cm in length and 15 cm in length, were inserted into the sand bed. The optimum temperature was 24 ~ 30 ℃, and rooting was 40 ~ 50 days after cutting.

2. Sowing: Xiandan flowers are collected in winter and sown in spring. The suitable temperature for germination is 22-24 ℃, and germinates 20-25 days after sowing. When 3-4 pairs of true leaves grow, the seedlings can be transferred to 8 cm pot.

3. Striping: the plants with many branches and dense branches of Xiandanhua were annularly peeled 20 cm away from the top and wrapped with peat and film, which could heal and take root for more than 2 months.

The Culture method of Xiandan Flower

1. Soil: the fertile, loose and well-drained acid sandy loam is the best soil for Xiandanhua culture. For pot cultivation, the mixture of culture soil, peat soil and coarse sand is suitable for pH at 5-5.5.

2. Watering: Xiandan flowers like to be wet and afraid of dryness, and keeping the basin soil moist is beneficial to shoot germination and leaf growth. However, if it is too wet for a long time, it is easy to cause part of the root system to rot and affect the growth and flowering.

3. Sunshine: Xiandan flowers need plenty of sunshine, the leaves are green and shiny, which is conducive to the formation of inflorescences, and the flowers are neat and bright. Proper shading in strong light in summer can prolong the flowering period.

4. Temperature: the optimum temperature for the growth of Xiandan flower is 15: 25 ℃, 24: 30 ℃ from March to September, 13: 18 ℃ from September to March of the following year. The winter temperature is not lower than 0 ℃, and it is easy to suffer frost damage if it is too low.

5. Fertilization: Xiandan peanuts are applied once every half a month with nitrogen, phosphorus, potassium, ferrous sulfate and horseshoe slices mixed with water and liquid fertilizer after ripening and fermentation.

6. Pruning: the pruning of Xiandan flowers is mostly carried out after coming out of the room in spring, mainly to properly thinning the branches of the plants in order to facilitate ventilation and light. In addition, if the heart is picked properly during flowering, it can be pregnant with buds and bloom.

7. Insect pests: Xiandan flowers are often harmed by leaf spot and anthracnose, which can be sprayed with 1000 times of acetic acid solution. Pests are harmful to shell insects and can be sprayed with 1500 times of omethoate EC.
