Let me introduce to you the knowledge about whether osmanthus trees can survive the winter outdoors in the north. Let's learn about it together.

Can osmanthus trees survive the winter outdoors in the north?

Osmanthus trees cannot safely survive the winter outdoors in the north. Although osmanthus trees have some cold resistance, capable of enduring temperatures as low as -13°C, they can easily be frostbitten or die if exposed to low temperatures for an extended period. It is recommended to place them in a well-lit area during winter, allowing the plants to bask in full-day sunlight, which can help raise their temperature. Additionally, it is crucial to control the watering properly.

Keeping osmanthus trees outdoors in winter

Osmanthus trees have excellent ornamental value and can be planted in the north, but they are not easy to manage. Osmanthus trees can grow normally at -5°C, but it becomes difficult for them to survive if the temperature drops further. Therefore, when the temperature falls below -5°C, osmanthus trees need to be moved indoors for care.

In the northeast, temperatures are low, sometimes even below -20 or -30°C. If osmanthus trees are left outdoors during winter, they can easily freeze to death. Moreover, in the north, osmanthus trees are usually planted in pots, and potted osmanthus trees have less cold resistance compared to those planted in the ground.

Additionally, there is a lot of snow in the north, and the melting snow can also affect their root systems. Therefore, osmanthus trees cannot survive the winter outdoors in the north. It is generally recommended to move them indoors for care during winter, or they may not survive.

How to keep osmanthus trees safe during the winter

Ventilation and lighting

We need to place them in a well-lit area for care to ensure adequate sunlight. The indoor environment is dry during winter, so it's necessary to frequently spray water to maintain humidity. Also, windows should be opened regularly for ventilation to ensure air circulation.

Temperature

To keep osmanthus trees safe during the winter, it is essential to control the temperature, keeping it between 0-5°C and exposing them to ample sunlight. Outdoor layering can be used, with transparent plastic film covering the entire osmanthus tree, or the sides can be sealed. The film can only be removed when the temperature exceeds 5°C.

Watering

Lastly, it is important to note that during the winter, watering osmanthus trees is not recommended. The soil should be kept dry because overly wet soil can cause frost damage to the trees. Also, do not let water droplets remain on the leaves of osmanthus trees, as they can freeze, which is not conducive to the trees' survival.

Fertilizing

Fertilizer is generally not needed in large amounts during winter, and it should be applied based on the plant's growth. If the plant grows quickly, it can be fertilized once or twice a month. If the growth is slow, fertilizing once every one or two months is sufficient.

The above introduction about whether osmanthus trees can survive the winter outdoors in the north aims to bring some floral knowledge to plant enthusiasts.
