The latest family culture method of hydrangea

Hydrangea originated in Japan and Sichuan, China, and was introduced to the United Kingdom in 1736. It is widely cultivated in Europe, the Netherlands, Germany and France. Varieties of hydrangea in red, blue and purple can be seen in florists, and there are many hydrangeas planted in front of small gardens and buildings. let's take a look at the family breeding methods of hydrangea flowers.

Family Culture Environment of Hydrangea

1. Temperature: the optimum temperature for the growth of hydrangea is 18-28 ℃, and the winter temperature is not lower than 5 ℃. Flower bud differentiation takes 6-8 weeks under the condition of 5-7 ℃. The temperature of 20 ℃ can promote flowering, maintain 16 ℃ after anthesis, and prolong the flowering period. But the heat makes the flowers fade quickly.

2. Humidity: the basin soil should be kept moist, but it should not be watered too much, especially in the rainy season to prevent rotting roots caused by waterlogging. It is better to dry indoor potted plants in winter. If it is too dry and wet, the leaves will rot easily.

3. Illumination: Hydrangea is a short-day plant, which is treated in the dark for more than 10 hours every day and forms flower buds in about 45-50 days. Usually cultivation should avoid the hot sun, and 60%-70% shading is the best.

4. Soil: the sandy loam with loose, fertile and good drainage is better. However, with the change of soil pH, the flower color of hydrangea changed greatly. In order to deepen the blue, aluminum sulfate can be applied during bud formation. To keep pink, lime can be applied to the soil.

Common propagation methods of Hydrangea

1. Ramet propagation: it should be carried out before sprouting in early spring. Separate the rooted branches from the mother plant, pot directly, watering should not be too much, maintain in the semi-shady place, wait for new buds to sprout and then transfer to normal maintenance.

2. Striping propagation: when the bud germinates, it can grow after 30 days, cut off from the mother plant in the next spring, transplant with soil, and blossom in the same year.

3. Cutting propagation: carried out in the plum rain season. Cutting the top twigs, about 20 cm long, picking off the lower leaves, cutting at the appropriate temperature of 13-18 ℃, rooting 15 days after cutting.

Maintenance method of hydrangea in four seasons

1. In spring, the withered branches of potted plants should be trimmed and the soil should be turned over to change the soil. Once or twice, dilute liquid fertilizer based on nitrogen fertilizer can be applied to promote the germination of branches and leaves.

2. Summer: it should be placed in a semi-shady place or under the curtain to prevent the scorching sun and prevent the leaves from yellowing and anxiety. Topdressing is applied once or twice before and after flowering to promote the reproduction of chlorophyll flowers. After the flower fade, the pedicel should be repaired in time to keep the posture beautiful. The basin soil is often moist, but it is necessary to prevent stagnant water after rain to prevent the succulent root of Hydrangea from rotting because of too much water.

3. Autumn: the maintenance method is the same as that in summer.

4. Winter: after the beginning of winter, the plants cultivated in the open field should keep the soil warm so that they can survive the winter safely; the potted plants can be placed in a warm place facing south to the sun and without cold wind. Although the withered leaves fall off in winter, the roots and branches still survive, and new leaves germinate in the next spring.
