Hydrangea cultivation methods and precautions 1 Selection of soil. In general, hydrangeas like humus-rich, well-drained slightly acidic soil, which contains organic fertilizer, which can be conducive to the growth of hydrangeas. 2 Suitable growth temperature. First of all, we need to understand the growth temperature of hydrangeas, generally the growth temperature of hydrangea is 18 28, and the winter temperature is not less than 5, 20 temperature can promote flowering and growth, so we also need to meet the temperature requirements, so that it can be conducive to the growth of hydrangeas; 3 Plenty of water.
Generally, hydrangeas grow under the condition of sufficient fertilizer and water, which can make hydrangea peanuts grow faster, hydrangea also prefers sufficient water, but it is not easy to water too much, generally in summer, the weather is relatively hot, you can spray some water on the leaf surface and on the ground, which is conducive to maintaining the humidity of the air; 4 Fertilize in moderation. Generally, in the stage of vigorous growth of hydrangea, it is necessary to give hydrangea sufficient nutrients, and you can apply rotten thin cake fertilizer water every half a month, which can promote the growth of hydrangea and make the hydrangea bloom larger, which is conducive to growth; 5 Moderate amount of light time. Generally, hydrangeas grow slowly in winter, so they need an appropriate amount of light time in winter, so it is recommended to put hydrangeas on the balcony to give them an appropriate amount of light time to promote the growth of hydrangeas, and at the same time, in summer, the sun is too large, so it is recommended to put them indoors for cultivation.
Hydrangea macrophylla, also known as hydrangea, is a plant species of the genus Hydrangea in the family Saxifrageae, also known as hydrangea in Japan. Hydrangea flowers are white and plump, large and beautiful, and their flower colors can be red and blue, which is pleasing to the eye and pleasant, and is a common potted ornamental flower.
Hydrangeas were cultivated earlier in China, and hydrangeas were planted in Jiangnan gardens built in the Ming and Qing dynasties.

Hydrangeas should not be kept indoors.
Each part of hydrangea has different concentrations of toxins, and when it blooms, it will also emit toxin particles, which are difficult to degrade when they accumulate indoors, which is harmful to the human body. Although hydrangeas are not sun-loving plants, it is difficult for indoor light and ventilation conditions to meet the growth requirements, and hydrangeas need 3 to 5 hours of light a day.
Hydrangea flowers are very beautiful and beautiful, and some varieties will also emit an aromatic smell, but this aromatic smell contains certain toxins, and the plants without odor will also release a small amount of toxin particles when they bloom, and these toxins accumulate indoors and have a high concentration, so they cannot be kept indoors.
Hydrangeas are generally planted as garden plants, and if they are only made into cut flowers, they can be placed in the interior decoration, and the hydrangeas should be maintained to avoid direct contact by children.
Maintaining hydrangea is relatively simple, it doesn't need too much sunlight to bloom, just keep it in the courtyard in a half-shaded and half-sunny place, you don't need to keep warm in winter, keep the wintering temperature at 5 12 degrees, don't put it in a place where the temperature is too high to overwinter, otherwise it will affect the hydrangea flowering.

Hydrangeas can be maintained indoors, but they must be grown indoors in a ventilated location. If the ventilation is poor, it will grow weakly, and it will be very bad for flowering.
In short, hydrangeas should not be placed indoors, not to be greedy for the beauty of flowers and want to pick to play, now I believe everyone knows that hydrangeas are poisonous, we must pay attention not to eat by mistake, especially children, easy to play and eat, which will cause very serious consequences, so it is best not to breed hydrangeas if there are children at home.
Precautions: Do not place hydrangeas in the bedroom when they enter the flowering period, as hydrangeas will have a lot of pollen when they bloom. The longer the flowers are in full bloom, the richer the pollen. Place the flowering hydrangeas in the bedroom.
As the air circulates, pollen enters the air and is then inhaled or in contact with the body, causing some discomfort. In addition, the whole plant of hydrangea is poisonous, and the toxins mainly exist in the juice.
Hydrangeas do not have long buds, or the buds are relatively small, and the petals have not yet opened, so they can be placed in the bedroom for maintenance. When hydrangeas have entered the flowering stage, it is best not to place them in the bedroom, but to move them outdoors for maintenance.
In particular, don't put the flowering hydrangeas in the bedroom, otherwise it will be very "hurtful", don't listen to persuasion. If there are no conditions for open cultivation, when the hydrangeas are in bloom, we can place them on a well-ventilated balcony or by a window where the family rarely visits.

The soil is preferably loose, fertile and well-drained sandy loam.
In addition to the hot summer when the sun is very strong, you need to shade or put it indoors to avoid direct sunlight, you should receive sufficient sunlight at other times, and there should be at least 4 hours of sunlight every day, so as to maintain year-round flowering. If the light is insufficient, if it grows in a shaded place for a long time, the plant is easy to grow and reduce the differentiation of flower buds.
Attention should be paid to the flowering period: after the differentiation of flower buds, phosphorus and potassium fertilizers should be increased. It is worth mentioning that the flower color is affected by the pH of the soil, and the acidic soil flowers are blue, and the alkaline soil flowers are red.
In order to darken the blue color, aluminum sulfate can be applied during the bud formation stage. To maintain the pink color, lime can be applied to the soil.
The soil should always be kept moist and dry, and there should be no shortage of water and drought, otherwise the leaves will turn yellow and fall off, affecting the growth and ornamental value; However, it is not allowed to water too much and the soil is too wet, otherwise the plants will grow, the flower buds will be differentiated, the flowers will bloom less, and even the roots will rot and die. Watering should master the principle of not drying, not watering, and watering thoroughly. In summer, when the temperature is high and the plants enter dormancy, watering should be controlled and fertilization should be stopped.
Factors influencing flowering:
1) Excessive watering or rain, long-term water accumulation in the pot, causing rotten roots, yellow leaves or long plants, all affect flowering. (2) Excessive fertilization, especially excessive nitrogen fertilizer, is easy to cause branches and leaves to grow, no flowering or sparse flowering, and poor flower quality. However, insufficient or no fertilization will also affect the normal growth and flowering of plants.
Therefore, in early spring or early autumn, more squamous potassium fertilizer should be applied appropriately. (3) The temperature is too high or too low, the room temperature is above 20 in winter, and the ventilation is poor, the branches and leaves are easy to grow, which affects the flowering of the next year, but the overwintering temperature is lower than 0, it is susceptible to frost damage, and the leaf edge becomes yellow and soft. Geraniums are also sensitive to temperature changes, and if they change sharply, they will cause the flowers to fall off.
4) The light is too strong, and the leaf edge is exposed to direct sunlight in summer, and the leaf edge is prone to sunburn, poor growth or flowers and leaves falling off.
5) If the topping is too heavy, there are few leaves for a long time, which will also delay the growth period, and the number of flowers and flowers is small. In addition, if the light is insufficient for a long time in winter and spring, it is easy to cause the plants to grow and not bloom, and even the flower buds that have been formed will shrink and dry up due to insufficient light. Therefore, in winter, attention should be paid to giving more sunlight.
