Hydrangeas have a certain ornamental value, but they are even more beautiful after blooming. Therefore, keeping a pot of hydrangeas outdoors is a very good choice. However, many people do not know when hydrangeas bloom. In fact, they usually bloom after June and look very beautiful after flowering. So, how many times do hydrangeas bloom in a year? Let's find out with the editor. This article is compiled by Fresh Flowers 24-Hour National Outstanding Florists and Quality Physical Flower Shop Alliance.
【One, When do hydrangeas bloom?】
Since the blooming period of hydrangeas is from June to August, they usually bloom in June. Although the blooming period is relatively short, they look very beautiful and are highly ornamental. If you want to change the color of hydrangeas, you can also choose to change the soil, which will cause the color of the hydrangeas to change with the soil.
The color of the flowers will also appear more unique, and increasing the temperature can extend the viewing period. However, high temperatures can cause the flowers to fade quickly. Hydrangeas are short-day plants, requiring more than 10 hours of darkness each day to form flower buds in about 45-50 days. Potted hydrangeas are commonly grown in 15-20 cm pots.
【Two, How many times do hydrangeas bloom in a year?】
Hydrangeas usually bloom in June every year. Some gardening enthusiasts ask how many times hydrangeas bloom in a year. In fact, they bloom only once. However, because the characteristic of Endless Summer hydrangeas is that both new and old branches bloom, often the flowers on the old branches have been faded for a long time before the new branches bloom, creating an illusion of blooming twice.
So, hydrangeas basically bloom only once and do not bloom multiple times. However, in a few special cases, they can bloom twice, but this requires careful cultivation. Only experienced gardeners can achieve this, so it is very difficult to make hydrangeas bloom twice.
【Three, Reasons why hydrangeas do not bloom】
<1. Improper pruning>
The blooming period of hydrangeas is from June to August. After the blooming 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 from June to August, resulting in reduced or no blooming.
<2. Insufficient light>
In home cultivation, hydrangeas are limited by conditions and receive less sunlight, which can cause the leaves to grow excessively and the plant to grow poorly. The excessive nutrients consumed by the leaves can lead to insufficient nutrition during flower bud differentiation, affecting blooming, so appropriate sunlight is necessary.
<3. Excessive nitrogen fertilizer>
Hydrangea flower bud differentiation is mainly based on nitrogen fertilizer in the early stage and phosphorus fertilizer in the later stage. However, excessive application of nitrogen and phosphorus fertilizers in autumn and winter can cause excessive plant nutrition, inhibiting growth and making it difficult for flower buds to differentiate, affecting blooming in the second year.
<Conclusion>
: Through the detailed introduction above, I believe everyone now knows when hydrangeas bloom. In fact, they usually bloom in June every year, but they fade quickly. Therefore, to extend the blooming period of hydrangeas, careful cultivation is necessary. As for how many times hydrangeas bloom in a year, usually they bloom only once.
