How to help Hydrangeas survive the winter
Do you know these? The knowledge about how hydrangeas survive the winter and the maintenance of hydrangeas in winter, the following editor will provide you with detailed answers
Hydrangeas need to be placed indoors for cultivation in winter. Hydrangeas are not cold-resistant plants, so the room temperature should be kept above 20 degrees in winter. Hydrangeas stop growing in winter and enter a dormant period, so the amount of watering should be reduced. The amount of fertilizer should also be reduced to avoid excessive nutrition due to excessive fertilization. Pest and disease problems also need attention. The following is a detailed introduction from these aspects.
1. Appropriate temperature
Hydrangeas are plants that like to grow in warm environments. Therefore, they have high requirements for temperature. In winter, when the temperature is low, hydrangeas can be cultivated indoors, but the temperature needs to be maintained at about 20 degrees. Hydrangeas prefer shade, but there is a large temperature difference in winter, so the temperature at night should not be lower than 10 degrees. The daytime temperature is relatively high, ensuring a constant temperature is fine.
2. Reduce watering
In winter, when the temperature is low, hydrangeas enter a dormant period and stop growing. The amount of watering must be reduced and watered once every half a month. Water thoroughly, and the soil in the pot needs to be kept moist. Water when the soil is half moist.
3. Reduce the amount of fertilizer
In winter, the use of fertilizer for hydrangeas can be reduced because they are in a dormant period, so applying fertilizer can easily lead to excessive nutrition. The branches and leaves of the flowers will become withered and rot. Fertilization needs to use diluted fertilizer. Using nitrogen fertilizer is best, and a thin fertilizer is fine.
4. Prevent diseases
In winter, the temperature is low, but hydrangeas can also have disease problems. Therefore, it is necessary to use pesticides for spraying to prevent the occurrence of diseases. If diseases are found, they need to be dealt with promptly. The rotten leaves and roots can be pruned and treated. Covering the hydrangeas with a plastic bag can keep them warm because the plastic bag is airtight and prevents the entry of cold air.
The above introduction on how to help hydrangeas survive the winter and the specific knowledge of winter maintenance of hydrangeas is for netizens' reference.
