Does Hydrangea Need Sunlight?
The editor will tell you whether hydrangea needs sunlight and the related knowledge of hydrangea maintenance precautions, let's understand together.
Summer is approaching, and in the southern regions, the hydrangea may already have mature buds, which will bloom in a few days. In the northern regions, the hydrangea is now孕育ing buds, which have not yet taken shape and need to wait until June to bloom. The temperature difference between the north and south has a significant impact on the blooming of hydrangeas.
The southern region is warm, and hydrangeas bloom early, while the northern region is cooler, and hydrangeas bloom late. The maintenance methods in the north and south cannot be unified. However, hydrangeas have a common characteristic: they do not like sunlight. Hydrangea leaves are large and numerous, and prolonged exposure to the sun can accelerate water evaporation.
Potted hydrangeas do not need sunlight and can even be kept in the shade throughout their care period. Without sunlight, hydrangeas can still grow normally and bloom. When it comes to blooming, most people think of providing ample sunlight, but hydrangeas are different; they can bloom without intense sunlight.
For potted hydrangeas kept outdoors, it is best to place them in shaded areas to reduce the time of direct sunlight exposure. Shortening the exposure time can significantly extend the blooming period. Also, it does not require frequent watering. With reduced light exposure, the evaporation of water from the leaves will decrease. If exposed to direct sunlight for an extended period, it is necessary to water every one or two days.
Does Hydrangea Need Sunlight?
Hydrangeas have a very fast rate of water evaporation, with large leaf area and numerous leaves. Combined with the vigorous growth of the branches and leaves, they dissipate water much faster than other similar plants and greenery. It is not recommended to expose hydrangeas to the sun for an extended period.
Potted hydrangeas are entirely different from those planted in the ground. The roots of ground-planted hydrangeas grow more vigorously, allowing them to absorb water from the soil without restriction. With strong roots, they can absorb enough water to support growth and blooming. In contrast, the root growth space of potted hydrangeas is limited, and the amount of water absorbed is also limited, insufficient to support the plant under direct sunlight.
Plant care should depend on the plant's growing habits. For potted flowers, prolonged exposure to the sun can indeed increase the number of blooms, but it is essential to keep up with fertilizing and watering. In my courtyard, the hydrangeas need to be watered once a day in the summer, which is very troublesome. They have been grown for many years with strong roots and absorb a lot of water.
Hydrangeas kept in semi-shade or under shade nets often have a better overall blooming state, while those exposed to direct sunlight have a shorter blooming period.
