Hydrangea is native to the provinces south of the Yangtze River in China. It is a plant that likes a warm and humid environment and is most afraid of the hot sun. Spring, summer and autumn is the growing period of hydrangea, and it is best to keep the soil moist in the basin. In order to prevent root fester, we should pay attention to drainage, not stagnant water. Fertilizer should be applied once a week to avoid the hot sun in summer. Prevent plants from growing best in the shade. Spray water properly when the air is dry, which is conducive to growth and clean the ash layer on the leaves. The color of hydrangea depends on the acidity and alkalinity of the soil. When the PH value is 6-7, the flower color is red. The flower color is blue when PH is about 5.5. Hydrangea is a short-day plant that can form flower buds after more than 10 hours of darkness every day. When promoting flowering cultivation, after 5 ℃ to 7 ℃ low temperature treatment for 6 to 8 weeks, the plant was placed in an environment of about 20 ℃, and then decreased to 16 ℃ when flower bud was seen, and it could blossom in about two weeks. When the hydrangea growth is too exuberant, you should prune or pick the heart in time, so as to control the growth and maintain the ideal perfect appearance. And make the plant blossom more. When the flowers fade, the branches should be cut short to promote the growth of new branches. When the new branches grow to 8 cm to 10 cm, they can be cut short again to make the lateral buds full and conducive to flowering in the coming year. Controlled watering in winter, more than 5 ℃ can survive the winter safely. The basin soil should be changed every spring. The basin soil is required to grow in a soil rich in humus, loose and well drained. It is very convenient without too many requirements. The propagation mode of hydrangea can choose the cutting method, the tender branches in early summer. Cuttings should have 2-3 nodes, the lower leaves should be removed, and the upper leaves should be cut in half, so as to prevent water evaporation and promote survival. Put it in the semi-shade after insertion to keep it humid and easy to take root. It can also carry out high-altitude striping propagation in the growing season, or ramet propagation before sprouting in spring.

It blossoms in summer and integrates large globose Cymes at the top of the branch, with white neutral flowers at the margin. The flowering period is from April to May, and the flower diameter is 18cm to 20cm, all of which are sterile flowers. The flowers bloom greenish at first, then turn white with fragrance. It is named because its shape is like hydrangea.

Second, how to grow hydrangea

Hydrangea like warm, moist and semi-shady environment, afraid of drought and waterlogging, not cold-resistant, like fat, moist, well-drained light loam, but strong adaptability. Therefore, it is better to use loose, fertile and well-drained sandy loam. The acidity and basicity of the soil had a great influence on the flower color of hydrangea, which was blue in acidic soil and red in alkaline soil. 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. Change the basin every spring and trim it properly to keep the plant shape beautiful.

If you want to raise hydrangea well, you must pay attention to the temperature and light of the surrounding environment. Hydrangea can only grow normally between 15 and 27 degrees, so try to transfer it to a sunny place indoors in winter, and the lowest temperature at room temperature should not be lower than five degrees, otherwise the hydrangea will freeze to death or stop growing. In summer, we should focus on cooling and shading, so that the leaves will not be scalded. Too strong sunlight will only cause the leaves to change color or even wither.

III. Culture methods of Hydrangea

1. Soil: loose, fertile and well-drained sandy loam is the best soil for hydrangea planting. However, the flower color is affected by soil acidity and alkalinity, acidic soil flowers are blue and alkaline soil flowers are red.

2. Watering: the potted soil planted with hydrangea 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 wet, the leaves will rot easily.

3. Lighting: Hydrangea is a short-day plant, usually cultivated to avoid the hot sun, 60% to 70% shade is the most ideal. When the light is too strong in midsummer, proper shading can prolong the flowering period.

4. 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, prolong the viewing period, and pay attention to the rapid discoloration of flowers caused by high temperature.

5. Fertilization: the flowering period of hydrangea is from June to July, the fertilizer and water should be sufficient during the flowering period, and fertilize once every semimonthly.

6. Pruning: after Hydrangea blossoms, attention should be paid to the removal of flower stems to promote the production of new branches. Proper pruning can keep the plant shape graceful.

7. Insect pests: Hydrangea is mainly caused by wilt, powdery mildew and leaf spot. Spray control with 65% Dysen zinc wettable powder 600 times solution. Insect pests are harmful to aphids and bug bugs and can be sprayed with 1500 times of omethoate EC.

In summer, we should focus on cooling and shading, so that the leaves will not be scalded. Too strong sunlight will only cause the leaves to change color or even wither.

⑵ watering and fertilization should be appropriate: more watering during bud gestation, more fertilization during dormant period, less watering during dormant period, less watering during dormant period, usually only need to maintain the wetness of soil surface when watering hydrangea, summer can be used to reduce the temperature around the foliage by spraying water, less watering and semi-dry in winter, more watering during budding, at least twice a day, fertilization should also be in place. In the bud period to apply thin fertilizer to hydrangea every ten days, you can add a little bit of ferrous sulfate to make alum fertilizer, or you can spray some liquid fertilizer to the leaves every half a month, which can make the buds blossom. Don't fertilize during the dormant period and let the hydrangea get enough rest.

⑶ weeding and pruning should be ruthless: when weeding is to be thoroughly pruned, the growing environment of hydrangea flowers should be kept clean at all times, and the weeds grabbing nutrients should be removed as soon as they are exposed. Never show mercy or miss the net. Generally speaking, in order to make the plant type more beautiful, it is necessary to pick the heart when there are too many new leaves, and we should also pay attention to pruning some overgrown and dense branches. in addition, the diseased branches and leaves after blooming also need our main pruning objects. these miscellaneous branches should be removed in time so as not to compete with the main branches for nutrition.

The sandy loam with loose, fertile and well-drained soil 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.
