How Hydrangeas Survive Winter
The editor will explain the introduction of green plants and flowers on how hydrangeas survive winter, and the editor will introduce next.
How Hydrangeas Survive Winter
Control temperature: Hydrangeas are not very cold-resistant, so the environmental temperature should be controlled above 10-15 degrees. Reduce watering: water every 10-15 days. Stop fertilizing: no absorption during dormancy, stop fertilizing. Control diseases: spray the plant surface with diluted mancozeb and slightly pour it into the soil.
1. -- Control Temperature --
Hydrangeas are not very cold-resistant and thrive at temperatures between 18-28 degrees. When the temperature drops to 4 degrees in winter, growth stops and the plant enters dormancy. It needs to be moved indoors, with the temperature controlled above 10-15 degrees, and placed in a position with scattered light.
2. -- Reduce Watering --
Hydrangeas require less water in winter, so water sparingly every 10-15 days, keeping the soil slightly dry. Excessively moist or waterlogged potting soil can freeze, causing root frostbite and hindering growth.
3. -- Stop Fertilizing --
Hydrangeas need plenty of nutrients during the growing period, but when they enter dormancy in winter, they do not absorb nutrients, so fertilizing should be stopped. Fertilizing at this time can cause the plant to end its dormancy prematurely, forcing it to sprout, leading to frost damage to the tender buds and potentially killing the plant.
4. -- Control Diseases --
Hydrangeas are prone to powdery mildew in winter, which can cause leaf rot in the early stages of the disease. Diseased branches and leaves should be cut off with a disinfected pair of scissors, and the plant surface should be sprayed with diluted mancozeb and slightly poured into the soil to prevent diseases.
That is the specific introduction on how hydrangeas survive winter. I hope everyone likes it!
