How to cultivate hydrangeas to make them bloom easily
Today, the editor will introduce some small experiences on how to cultivate hydrangeas to make them bloom easily, as well as the cultivation methods and precautions for hydrangeas. Let me explain in detail for you next.
In recent years, hydrangeas (Hydrangea) have become increasingly popular. They have fewer diseases and pests than roses and have a particularly long blooming period. Most varieties can bloom from early summer to late autumn. With proper care, they can bloom repeatedly every year. They have abundant flowers and a variety of colors, which are particularly appealing.
1. Sufficient sunlight
Many people have heard that hydrangeas are a plant that can tolerate semi-shade (not fond of semi-shade), and they do not like to be kept in a semi-shady place for a long time. Only in excessively high temperatures, such as when the temperature exceeds 35 degrees Celsius in summer, it is necessary to provide appropriate shading at noon and in the afternoon.
However, in the cool weather of spring and autumn, when the temperature is not high and the sunlight is not intense, it is best to provide full-day sun exposure. As long as the leaves and flowers are not sunburned, try to expose them to more sunlight.
If the sunlight is too intense, and the leaves or flowers are sunburned, reduce the sunlight promptly, move them to a slightly shaded area, or install a sunshade net. After all, hydrangeas are plants with a high bloom rate and prefer sunlight.
Some varieties of hydrangeas are not very resistant to sun exposure, and overly intense sunlight can easily cause the petals to scorch, reducing their ornamental value.
2. Ventilation in the environment
Many people cannot cultivate potted hydrangeas well because they are kept indoors, whether on a south-facing or east-facing balcony with adequate sunlight, the ventilation is not as good as outdoors.
Even on a balcony with good air circulation, it is usually one side against the wall, while in the courtyard, there is ventilation on all sides. The ventilation in the courtyard or on the terrace is definitely better than on the balcony, making it easier to care for potted hydrangeas.
If you are growing potted hydrangeas on a balcony, you need to increase the ventilation and light transmission between the plants, and try to place them in a position with good ventilation and adequate sunlight.
If it is a closed balcony, it is recommended not to grow hydrangeas. There are many other beautiful flowering indoor ornamental plants to choose from (such as geraniums, begonias, and impatiens).
3. The impact of potting soil on hydrangeas

In addition, when planting hydrangeas, you must match them with suitable potting soil. You need to put a lot of thought into the soil mixture. Some friends' potted hydrangeas have leaves that easily scorch at the edges, and the tips and edges of the leaves are prone to drying and rotting, which may be due to the soil not being breathable.
If the soil cannot dry out in time, it is prone to root suffocation, which means that the roots in the soil do not have good ventilation and cannot breathe, easily becoming suffocated. The first sign of this is leaf scorching.
Moreover, if the soil is not breathable and loose enough, it can easily cause root rot, which can lead to poor growth of flowers and leaves, affecting blooming and leaf health.
Do not use ordinary garden soil or poor-quality nutrient soil for planting potted hydrangeas.
Potted hydrangeas can be cultivated using a better-quality universal nutrient soil.
Of course, it is best to mix your own potting soil, such as using peat soil, coarse coconut fiber, and perlite in a ratio of 6:2:2. You can also mix in some decomposed leaf soil to increase the humus in the soil, and you should also mix in some slow-release fertilizer to increase fertility.
4.注意事项 when repotting
If you have just bought a potted hydrangea that is still blooming, do not rush to repot it. Wait until after it has finished blooming, then cut off the spent flowers and proceed with repotting and changing the soil.
The potted hydrangea you bought was originally planted in garden soil. You can rinse off the topsoil with water (or directly remove the topsoil) until the roots are exposed, and then add new soil, planting it in a pot one size larger than before.
Potted hydrangeas can be planted in common green mountain pots or plastic pots. If using plastic pots, you can drill more holes in the side of the pot to increase ventilation, or even dig a few vertical openings on the side of the pot to increase drainage and ventilation.
