How to Care for Hydrangea Flowers to Make Them Last Longer
Summary: This article discusses related topics such as how to care for hydrangea flowers to make them last longer and the maintenance methods for cut hydrangeas in terms of green plants. Next, the editor will introduce these to the netizens.
When hydrangeas bloom, they make the garden beautiful again after the climbing roses have faded. Hydrangeas have an exceptionally long blooming period; with proper care, they can bloom from early summer to the end of summer and into autumn. However, some gardeners find that their hydrangeas fade after a short period, sometimes not even lasting a month. To make hydrangeas bloom for 100 days, master four "tricks" to make them look like plastic flowers and prevent them from fading for a long time.
Fertilize BeforeBlooming
The size of hydrangea flowers, the brightness of their color, and the length of their blooming period are all related to fertilization before flowering. It is very necessary to apply a high-phosphorus and potassium fertilizer once every 7-10 days before the flowers bloom. This allows the flower buds to swell rapidly and store enough nutrients to maintain a blooming period of about 100 days. If the flower buds are not fertilized enough, the flowers will be small, the color will be dull, and if the nutrient supply is insufficient after a period of blooming, the flowers will age and fade quickly.
Therefore, if your hydrangea flowers are still in bud, it is essential to pay attention to fertilization and not rely on the chance that they will bloom without it. While they can indeed bloom without fertilization, the blooming period and flower quality will not be comparable to those that have been fertilized. If your hydrangea flowers are already in bloom, it is not recommended to fertilize, as it will not extend the blooming period and may even shorten it. Unless your hydrangea has only bloomed a few flowers and many others are still in bud, and you haven't noticed fertilizing in the early stage, then it is still possible to supplement phosphorus and potassium fertilizers, which will be very beneficial for the growth of those flower buds.
Prevent Direct Sunlight During Flowering
Hydrangeas are not tolerant of strong sunlight, and especially during the early stages of flowering, they will wilt in the sun. Therefore, after the hydrangeas are in full bloom, do not keep them in a place with too much sunlight. Strong sunlight and high temperatures will cause the hydrangeas to age quickly, ending the blooming period early. Keeping them in a semi-shaded environment will keep the temperature lower and extend the blooming period, making them look like plastic flowers.

However, it is also important to note that during the flowering period, hydrangeas should not be kept in a place with too little sunlight. If there is too little sunlight, photosynthesis will not be sufficient, and the flowers will also fade prematurely. Keeping them in a semi-shaded area or a place where they can be exposed to the sun in the morning and afternoon is most suitable. If there is no suitable place for hydrangeas to grow,遮阳 between 10 am and 4 or 5 pm and expose them to direct sunlight at other times.
Water Properly
During the blooming period, hydrangeas should not be too dry or too wet. If they are too dry, the flowers will wilt and age quickly. If they are too wet, it will affect the root respiration, leading to a shortened blooming period or even rotting roots and yellow leaves. Therefore, after the flowers bloom, we need to pay attention to observations. If the leaves are slightly wilted in the morning and evening, water them promptly. If the leaves and flowers look normal and are not drooping, do not water them.
In addition to watering, for indoor potted hydrangeas, it is best not to spray water on the leaves or flowers during the flowering period. In indoor environments with poor ventilation, water on the leaves and flowers cannot evaporate for a long time, which can lead to the activation of various diseases and pests, causing them to multiply and resulting in the hydrangeas getting sick or infested with pests. Some gardeners may find that their hydrangea petals rot or dry out; consider whether they often spray water on the entire plant.
