How long does hydrangea bloom
This article introduces how long hydrangea blooms and teaches you the correct maintenance knowledge of green plants and flowers. What follows is a comprehensive introduction.
Hydrangea has a certain ornamental value, but it is more attractive after blooming. Therefore, raising a pot of hydrangea outdoors is a very good choice. However, many people do not know when hydrangea blooms. In fact, it usually blooms after June and is very beautiful after flowering. So, how many times does hydrangea bloom in a year? Let's find out together with the editor.
【One, when does hydrangea bloom】
Since the flowering period of hydrangea is from June to August, the plant will bloom in early June. Although the flowering period is relatively short, the flowers look very beautiful and have high ornamental value. To change the color of hydrangea, you can also choose to change the soil, and the color of the hydrangea will change with the soil.
The color of the flowers will also be more unique, and raising the temperature can extend the viewing period. However, high temperatures cause the flowers to fade quickly. Hydrangea is a short-day plant and requires over 10 hours of darkness daily to form flower buds in about 45-50 days. Potted hydrangea is commonly planted in 15-20 cm pots.
【Two, how many times does hydrangea bloom in a year】
Hydrangea usually blooms in June every year. Some flower friends ask how many times hydrangea blooms in a year. In fact, it only blooms once. However, because the characteristic of endless summer hydrangea is that both new and old branches bloom, often the flowers on the old branches have already faded when the new branches bloom, creating an illusion of blooming twice.
So, hydrangea basically blooms only once and does not bloom multiple times. However, in a few cases, it can bloom twice, but the method is special and requires careful maintenance. Only experienced gardeners can achieve this, so it is very difficult to make hydrangea bloom twice.
【Three, reasons why hydrangea does not bloom】
<1. Improper pruning>
The flowering period of hydrangea is from June to August. After the flowering period, the flower branches should be pruned to reduce nutrient loss. If the plant grows too vigorously and is heavily pruned in early spring, it is difficult to form flower branches in June to August, resulting in reduced or no flowering.
<2. Insufficient light>
In home cultivation, hydrangea is limited by conditions and receives less sunlight, which can cause the leaves to grow excessively and the plant to grow poorly. The excessive consumption of nutrients by the leaves leads to insufficient nutrition during flower bud differentiation, affecting flowering. Therefore, proper sunlight is necessary.
<3. Excessive nitrogen fertilizer>
In the early stage of flower bud differentiation, nitrogen fertilizer is the main nutrient, and in the differentiation stage, phosphorus fertilizer is the main nutrient. However, if excessive nitrogen and phosphorus fertilizers are applied in autumn and winter, it can cause excessive plant nutrition, inhibit growth, and make it difficult for flower buds to differentiate, affecting the next year's flowering.
<Conclusion>
: Through the detailed introduction above, I believe everyone now knows when hydrangea blooms. In fact, hydrangea will bloom in June every year, but it will fade quickly. Therefore, to extend the flowering period of hydrangea, careful maintenance is necessary. As for how many times hydrangea blooms in a year, it usually blooms only once.
The sharing above on how long hydrangea blooms and the introduction of correct maintenance knowledge is for everyone's reference.
