Growth Habits of Hydrangeas
Hydrangeas prefer an environment with plenty of light and good ventilation, with a suitable temperature of 15°C-25°C, and they like neutral or slightly acidic soil. They have a long growth cycle, generally taking 3-4 years to reach their best ornamental effect. Hydrangea is a deciduous shrub that enters a dormant period in winter. This is also one of the main reasons for its leaf drop.
Why do hydrangeas drop leaves in winter?
The leaves of hydrangeas gradually age during their growth process and will fall off if the environmental conditions are not suitable. In winter, factors such as insufficient light, low temperatures, and high humidity will affect their normal growth, leading to leaf drop.
Leaf pigments gradually fade
As the leaves age, the pigments within them gradually fade. In winter, hydrangeas are more affected by environmental factors, and the rate of pigment fading will accelerate, making the phenomenon of leaf drop more pronounced.
Environmental temperature drops
Hydrangeas like a warm environment, but in winter, the temperature drops, affecting their normal growth and causing leaves to fall.
Insufficient light
Hydrangeas need sufficient light for photosynthesis. If there is not enough light, it will affect their normal growth. In winter, the lack of sunlight is also one of the reasons for hydrangea leaf drop.
Lack of water and high humidity
Hydrangeas need a moderate amount of water during their growing period. If they lack water or the environmental humidity is too high, it will affect their normal growth and development. In winter, indoor humidity is often high, which can easily lead to hydrangea leaf drop.
Lifespan expires
The lifespan of a hydrangea is generally 3-4 years. After this period, it enters an aging stage, and leaf drop becomes more noticeable.
Pest and disease infestation
Pests and diseases are also a reason for hydrangea leaf drop. If the leaves are infested by pests or diseases, it will lead to leaf drop.
How to prevent hydrangeas from dropping leaves in winter
To prevent hydrangeas from dropping a large number of leaves in winter, we need to care for them scientifically. The specific measures are as follows:
Pay attention to watering and fertilizing
Hydrangeas need a moderate amount of water and nutrients to grow healthily, but you should not overwater or over-fertilize, as this can lead to nutrient excess and root rot.
Reasonable placement
Hydrangeas like an environment with plenty of light and good ventilation. In winter, try to place them in a sunny, well-ventilated location.
Control indoor temperature and humidity
In winter, pay attention to controlling indoor temperature and humidity to avoid the effects of excessively low temperatures and high humidity on the hydrangea.
Strengthen pest and disease control
Hydrangeas are susceptible to pests and diseases. It is important to detect them promptly and take effective control measures to avoid affecting their growth.
Timely pruning and tidying
Winter is the dormant period for hydrangeas, so it is appropriate to prune and tidy them up, which is beneficial for their healthy growth.
Summary: Scientific care for hydrangeas to make them more beautiful
Hydrangea is a beautiful ornamental plant, but it also needs scientific care to maintain its beauty. In winter, pay attention to controlling the indoor environment, strengthening pest and disease control, and watering and fertilizing reasonably to allow the hydrangea to grow healthily and make our homes more beautiful.
