How to Manage Hydrangeas for Winter
Today, the editor will explain the topic of how to manage hydrangeas for winter. Let's take a look together!
How to Manage Hydrangeas for Winter
Warmth Measures: Hydrangeas prefer warmth, so during winter care, the environmental temperature should be maintained above 15 degrees. Sufficient Light: The winter sun is gentle, and receiving full-day sunlight can promote growth. Water and Fertilizer Control: Water when the soil surface is dry and stop fertilizing. Ventilation Management: Ventilate during the warmer afternoons to prevent growth issues caused by long-term exposure to stuffy environments.
1. -- Warmth Measures --
Hydrangeas thrive in warm and humid environments and are not cold-tolerant. The most suitable growth temperature is between 18-28 degrees. When temperatures drop below 10 degrees in winter, they are prone to frost damage. In the north, they need to be moved indoors, maintaining a temperature above 15 degrees. In the south, they can be placed in a south-facing position and wrapped in plastic bags for insulation, or left outdoors.
2. -- Sufficient Light --
During winter care, hydrangeas need ample sunlight. The winter sun is relatively gentle, and they can receive full-day sunlight. This not only raises the temperature through sunlight but also promotes photosynthesis and growth. Placing them in dark and poorly lit areas can cause the temperature of the hydrangea to drop, leading to frostbite.
3. -- Water and Fertilizer Control --
In winter, with lower temperatures, hydrangeas grow slowly and their water requirements decrease. It is necessary to control soil moisture. When the soil surface is dry, water with water at room temperature. Do not apply additional fertilizer at this time, as excessive fertilizer in the soil can cause fertilizer damage, placing a burden on the roots.
4. -- Ventilation Management --
When hydrangeas are overwintering indoors, it is necessary to ventilate during the warmer afternoons. Long-term exposure to stuffy environments can slow down growth. Excessively humid and poorly ventilated conditions can cause leaf rot. When using bags for insulation, the plastic bags should be opened during the afternoons.
