How to Care for Hydrangeas Overwintering Outdoors
Hydrangeas need to be protected from the cold when overwintering outdoors. You can wrap the base of the plant with plastic film to prevent the cold from damaging the hydrangeas, which could lead to withering and leaf drop. Additionally, winter is a good time for pruning hydrangeas. It's best to use sharp, disinfected scissors to remove the unhealthy, small, and disease-prone leaves.
1. -- Protective Measures --
Hydrangeas overwintering outdoors need to be properly insulated because the plants can only tolerate temperatures as low as 5 degrees Celsius. If the temperature drops below 5 degrees, the hydrangeas will be frostbitten, causing leaves to fall. Therefore, it's necessary to wrap the base of the plant with plastic film to protect the hydrangeas from the cold.
2. -- Pruning --
When growing hydrangeas, pruning is necessary. Since the temperature in winter is relatively low, the leaves of the plant may wither, so you need to cut them off with a sharp pair of scissors to save nutrients for the hydrangeas to better survive the winter.
3. -- Lighting Conditions --
Hydrangeas are plants that enjoy a lot of light, but the sunlight in winter is weak. Therefore, when caring for them, it's necessary to place the plants in a well-lit area and supplement with a flashlight to provide adequate lighting, preventing the hydrangeas from poor growth.
4. -- Reducing Watering --
When watering hydrangeas in winter, you should reduce the amount of water given to the plant because the cold winter temperatures can lead to soil积水 if watered frequently, which may cause the hydrangea roots to rot and be unable to absorb nutrients properly.
The above is a comprehensive introduction on how to care for hydrangeas overwintering outdoors, hoping to provide some knowledge on green plants for plant enthusiasts.
