Egg flower, also known as Burmese gardenia, egg yolk flower, big season flower, etc., is a deciduous shrub or small tree of Apocynaceae. It is widely planted as one of the "five trees and six flowers" by Buddhist monasteries in Xishuangbanna, China and some Southeast Asian countries. and the ornamental value is high, the whole tree appears to be whirling and symmetrical, natural and beautiful, let's take a look at how to raise potted egg flowers!

Growth habits of egg blossom

Egg flower is a positive tree species, sexually fond of high temperature, moist and sunny environment, but can also grow in semi-shady environment, but branches grow only in shade environment, flowering few or leaves do not blossom. The acid sandy loam soil which is deep, fertile, permeable and rich in organic matter is the best soil for egg flower planting. Drought tolerance, avoid waterlogging, good stress resistance, but drought is not conducive to plant development, serious poor growth, waterlogging is easy to cause root rot. The cold tolerance is poor, and the most suitable temperature for growth is 20: 26 ℃. It is vulnerable to chilling injury when it is lower than 8 ℃ for a long time during overwintering. In the vast cities and towns south of the Tropic of Cancer in China, open-field cultivation can generally survive the winter safely, but it is only suitable for pot planting in central and North China, and overwintering in greenhouse in winter.

Propagation methods of egg blossom

1. Cuttage: cuttings of egg blossom branches are easy to survive, mainly through cutting propagation. In places suitable for open field cultivation in the tropics and subtropics, cutting can be carried out all the year round. Select 1-2-year-old stout branches, cut 20-30 cm long branches from the base of the branches, let the white milk from the cut dry, place in a cool and ventilated place for 2-3 days, and then insert the cuttings into the culture soil, 30-35 days can take root.

2. Sowing: egg flower does not bear much fruit, but most varieties in the open field can also collect a small amount of seeds. The optimum temperature for seed germination is 18-24 ℃, and it is generally sown with picking. Spread evenly at intervals of 5 to 6 centimeters, then cover with a thin layer of sand or coconut bran. Appropriate amount of water to keep the matrix moist. It takes about 8 to 12 days in spring and 5 days in summer to germinate and sprout, and then carry out general routine management to keep it moist, but the seedling bed can not be waterlogged.

3. Grafting: the grafting of egg flower is easy to operate because of the strong affinity between rootstock and scion, and the survival rate is very high. It can be carried out all year round in tropical and subtropical areas such as South China, but it is best in spring and autumn. It is better to stabilize the air temperature above 18% in winter and spring, but it should also avoid the long-term weather of Rain Water in winter and summer.

How to raise potted egg blossoms?

1. Soil: egg flower is not strict to the soil, and the planting effect is the best in the loose soil with more humus. After planting egg flowers, set them indoors to avoid shade, see weak light a week later, and then put them in a sunny place after half a month.

2. Watering: egg flowers like to be wet and resistant to drought, but they are afraid of waterlogging. Therefore, watering should be moderate, grasp the principle of no dry, no watering, no watering, no waterlogging. In the spring and autumn interval, the soil is watered once every day from 1 to 2 days, once in the morning on a sunny day in summer, and once again in the evening if the soil is dry. In the rainy season, attention should be paid to pouring the stagnant water in the basin to prevent rotting roots, and once every ten days and a half months in winter to keep the basin soil slightly moist and dry.

3, fertilization: egg flower likes fertilizer, when potting or turning the basin to change soil, it is appropriate to add 20 grams to 30 grams of bone powder, 50 grams to 80 grams of superphosphate (because it is born in calcareous soil, pay attention to calcium), from May to October, 10 to 15 days to apply a weak mature organic fertilizer or nitrogen, phosphorus and potassium compound fertilizer, avoid single application of nitrogen fertilizer, prevent apprentice growth, do not apply fertilizer in winter.

4. Illumination: egg flower is a strong positive flower, the more sunshine is, the more luxuriant the growth is, and the flowers are more and more fragrant. Except for shade for 7 to 10 days after potting or changing soil, the rest of the time should be placed in a sunny place. Although it can also grow in a semi-shady environment, it only grows branches in a shady environment, with few flowers or long leaves without flowering.

5. Change the basin: the egg flower grows rapidly and needs to be changed once a year in spring. The pot soil can be mixed with 4 parts of garden soil, 4 parts of horse dung soil and 2 parts of river sand. 100 grams of cake fertilizer or sauce dregs and 50 grams of superphosphate or bone powder are added in each basin. After the pot was changed and planted, Grain Rain was watered thoroughly, and the front and rear of the plant was moved to the outdoor sunny place.
