Hydrangea should be cultivated in a warm environment. It grows fastest when the outside temperature is between 20 and 28 degrees, and it is conducive to the differentiation of flower buds. When the temperature exceeds 20 degrees, it can bloom as soon as possible, but the temperature after the flower blooms must be controlled at around 16 degrees. Only in this way can its flowering period be extended. Hydrangea is also a short-day plant. During the cultivation period, it cannot be placed in the sun for a long time. It must be placed in a dark environment for more than 10 hours a day, which is very beneficial to the formation of flower buds.

1. During the cultivation period of hydrangea, you must pay attention to the supply of water and fertilizer. When this plant is cultivated in a flowerpot, it is necessary to water it in time after the budding period in spring every year, and keep the soil in the pot moist. Only in this way can it promote its normal growth and ensure that the leaves do not wither. June to July each year is the flowering period of hydrangea. At this time, fertilizer and water must be adequately supplied. In addition to watering every 2 to 3 days, topdressing should be applied every half a month.

2. When growing hydrangeas, try not to expose them to direct sunlight, especially in hot summer. They must be shaded as necessary. It is ideal to allow them to receive 60% to 70% sunlight. If hydrangeas are exposed to strong light for a long time, it will affect their flowering period and cause spots to appear on their leaves, which will adversely affect the ornamental value of the plant.

3. Hydrangeas often have diseases and insect pests during the cultivation period. Powdery mildew and night shift disease are the most common diseases of this plant. When these diseases appear, spray the wettable powder of chlorpyrifos in time. Hydrangeas are also prone to aphids during their growth period. When these pests appear again, spray omethoate in time and pay attention to environmental ventilation. This will make the diseases and insect pests disappear as soon as possible and allow the hydrangeas to grow quickly.
