How to help Hydrangeas planted in the ground survive the winter
When caring for hydrangeas planted in the ground during the winter, it is necessary to build a greenhouse for them to prevent the plants from being frozen and affecting their blooming the following year. Moreover, it's important to reduce the frequency of watering the hydrangeas, and when watering, the water temperature should be controlled around 15 degrees to prevent the plant's roots from being frozen. Note that it is strictly forbidden to fertilize the hydrangeas during the winter.
1. -- Building a greenhouse --
When caring for hydrangeas planted in the ground during the winter, insert stainless steel frames around the plants and then cover the frames with a plastic windproof film to create a greenhouse for the hydrangeas, preventing the plants from being injured by the cold wind. When the temperature drops below -10 degrees, it is best to transplant the hydrangeas into pots and care for them indoors.
2. -- Supplementing water --
When caring for hydrangeas during the winter, reduce the frequency of watering the plants to prevent accumulated water in the potting soil, which could lead to root rot. When watering, let the water sit at room temperature for about 24 hours, wait for the water temperature to match the room temperature before watering the hydrangeas, to prevent the roots from being frozen.
3. -- Stopping fertilization --
Hydrangeas enter a dormant period during the winter, and the plants stop growing. Therefore, do not apply fertilizer to them, otherwise, the hydrangeas may suffer from fertilizer damage. However, before winter arrives, it is necessary to apply a dose of decomposed fertilizer to the hydrangeas to increase the soil's temperature and help the plants survive the winter safely.
4. -- Providing light --
The winter sun is relatively warm and the light is weak, which can provide full-day sunlight for the hydrangeas, promoting better blooming of flowers the following year. Note that on sunny days, it is necessary to open the top of the greenhouse to strengthen the air circulation inside the greenhouse and prevent the hydrangeas from suffering from diseases and pests.
