How to raise dragon spit pearl flower?

Dragon spit pearl flower for verbenaceae daqing shrubs, like warm, humid and sunny semi-shade environment, not cold-resistant, distributed in western tropical Africa, Mexico, flower shape strange, flowering luxuriant, mainly used for greenhouse cultivation viewing, can be used as flower racks, but also for potted decoration windowsill and summer small courtyard, below we will take a look at how to raise dragon spit pearl flower!

Growth and Distribution of Puccinellia arundinacea

Dragon Tuzhu likes warm, humid and sunny semi-shade environment, not cold. The optimum temperature for growth is 18~30℃ from February to October, and 13~16℃ from October to February of the following year. Winter temperature is not lower than 8℃, 5℃ below the stem and leaf easy to suffer from freezing injury, light caused by deciduous, heavy tender stem wilt. Vegetative growth period temperature can be higher, 30℃ above high temperature, as long as sufficient water supply, can still grow normally. The temperature of reproductive growth, i.e. flowering stage, should be lower, about 17℃.

Breeding method of dragon pearl flower

1, cuttage: Dragon Tuzhu cuttage is generally carried out in May to June every year, optional top shoots of healthy disease-free branches, but also the lower part of the old branches cut into 8~10 cm stem segments as cuttings. Cuttings can be used peat, pearlite, rotten leaf soil, river sand and vermiculite matrix, spring and autumn cutting is the best, cutting temperature is 21℃, cutting bed temperature is 26℃, very favorable for rooting, after 3 weeks can root.

2. Sowing: The seed life of Dragon Spitting Pearl Flower is short, and it is sown immediately after harvest. Sowing can be carried out in shallow pots from March to April every year, the temperature is kept at 24℃, seedlings can emerge in 10 days, seedlings can be transplanted in pots when they are ten centimeters high, and flowers can be produced in the second year. Seeding method is not easy to survive, it is recommended to use cuttage propagation.

1, change pots: potted dragon spit beads commonly used 12~15 cm pots, each pot can be planted 3 plants. Generally every 1~2 years for a pot, for pot time in early spring or after the flowers can fade. When changing pots, first pad the drain holes with broken tiles, then put in a small amount of bone powder as base fertilizer, and then put in new culture soil (4 parts of humus soil, 4 parts of garden soil, 2 parts of sand), plant good plants, leaving 2~3 cm along the mouth for fertilization and watering. After changing pots, pour water thoroughly, put them in the shade to slow down the seedlings, and move them to a sunny place for maintenance.

2. Watering: Dragon Tuzhu is sensitive to moisture and needs sufficient moisture during its growth period. The growth period of stems and leaves should keep the saline soil moist, but the watering should not be excessive. The water amount is too large, resulting in only long vines without flowering, even yellowing and falling leaves, root rot and death. If the branches wither, stop watering, let them recover and sprout new leaves. Summer high temperature season should be fully watered, appropriate shade. In winter, water should be reduced to make it dormant in order to survive safely.

3, light: Dragon spit beads need sufficient light in winter, summer weather is too hot to shade, otherwise the leaves yellow. When the light is insufficient, it will cause tendrils to grow and not bloom. Flower bud differentiation was not affected by photoperiod, but strong light promoted flower bud differentiation and development. In the dark should not be placed for too long, in the temperature above 21℃, more than 24 hours, will fall flowers.

4, soil: Longtuzhu potted culture soil or peat soil and coarse sand mixed soil. The soil is fertile, loose and well drained sandy loam.

5, fertilization: Longtuzhu fertilization should not be too much, fertilization once every half month, flowering season to apply 1~2 times phosphorus and potassium fertilizer, every 7~10 days to apply a decomposed thin cake fertilizer water, continuous application of 3~4 times fertilizer can be reduced in winter watering and stop fertilization. If yellowing phenomenon is found in the cultivation process, it can be combined with topdressing application, 0.2% ferrous sulfate water, which can make the leaves gradually turn from yellow to green.

6. Pruning: When Longtuzhu grows to 15 cm after cutting seedlings or seeding seedlings are potted, the branches are cut at 10 cm from the mouth of the pot to promote the germination of sturdy new branches. Growth period should strictly control the height of branches, pay attention to topping, in order to branch neat, dense flowering in the future. Half a month after topping, apply bijiu or chlormequat to control plant height to achieve short plants, luxuriant leaves and more flowers.
