Culture method of egg flower

Egg flower, also known as Burmese gardenia, egg yolk flower, big season flower, etc., is a deciduous shrub or small tree of the family Apocynaceae. In South China, Guangdong, Guangxi, Yunnan and other places are widely used in parks, courtyards, green belts, lawns and other greening and beautification, while in the north, they are mostly used for potted ornamental plants. Let's take a look at the breeding methods of egg flowers.

Growth habits of egg blossom

Egg flower is a positive tree species, which is sexually fond of high temperature, moist and sunny environment, but it can also grow in semi-shady environment, but the branches grow only in shade environment, and the leaves do not blossom, while yellow egg flowers grow in shade and humid environment. the branches will grow gas and root. The acid sandy loam soil with deep and fertile, good permeability and rich organic matter is the best. When the soil is barren, the growth and development is poor, the flower shape is small and the flower color is dark. Drought tolerance, waterlogging, good 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.

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. The cuttings were inserted into a clean loam sand bed in the shade shed, and then sprayed with water every other day to keep the substrate moist and take root in 30-35 days. As long as it is not waterlogged and keeps the soil moist, it is very easy to survive.

2. Sowing: egg flower does not bear much fruit, but a small amount of seeds can be collected from most varieties in the open field, and the seeds will split naturally when they are ripe. The seeds in the pods will be taken out and sown in the rain-proof shed in the nursery of sandy soil. The optimum temperature for germination is 18-24 ℃, generally sowing with picking.

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.

Culture method of egg flower

1. Soil: egg flower is not strict to the soil, and the planting effect is the best in the loose soil with more humus.

2. Lighting: egg flowers are planted and placed indoors to avoid shade. A week later, weak light can be seen, and then after half a month, it can be placed in a sunny place.

3. Watering: egg flowers like to be moist, some slightly resistant to drought, avoid waterlogging, watering must be moderate, usually do not dry do not water, dry water immediately.

4. Fertilization: the rotten liquid fertilizer was applied every 10 days from June to November, and the concentration was controlled at about 15%.

5. Temperature: egg flowers can be planted in the open field in the south, and pot plants in the north should be moved into the indoor south window in the middle and last ten days of October, and the room temperature should be above 10 ℃. Low temperature and poor indoor ventilation will make the plants lose leaves.

6. Pruning: if egg flowers need dwarfing plants, they can be pruned properly after falling leaves every winter to promote lateral branches.

7. Changing pots: egg flowers grow rapidly. It is necessary to change pots once a year in spring, renew potted soil and apply sufficient basic fertilizer in order to flourish flowers and leaves.
