How do tulips survive the winter?

Tulips have high ornamental value and are relatively cold-resistant plants. Tulips can withstand temperatures as low as -14 degrees Celsius and can survive the winter normally in most parts of my country. If the winter temperature does not drop below -14℃, tulips can overwinter in the open air. So how do tulips survive the winter? Let’s take a look with the editor below.

1. Temperature management

Tulips prefer a warmer environment in winter. It is best to control the temperature at 9-13℃, or around 10℃. The maximum should not exceed 20℃, and the minimum should not be lower than -3 to 5℃. If the temperature is low in winter, you can cover the tulips with plastic bags and place them in a sunny, sheltered location with adequate ventilation to ensure their safe wintering.

2. Proper ventilation

During the winter, moderate ventilation is required to maintain air circulation. However, the plants should not be exposed to strong winds and should be protected.

3. Reduce moisture

The temperature is low in winter, water evaporates slowly, and tulips are also in a dormant period. The amount of watering should be controlled to keep the soil slightly moist, and avoid excessive watering that may cause root rot. When watering, avoid doing it when the temperature is low to reduce the evaporation rate of water and keep the soil moist. If the tulips are in a container, you can provide drainage holes in the bottom to ensure that excess water can drain away quickly to avoid problems caused by waterlogging.

4. Stop fertilizing

During the winter, tulips do not need excessive fertilization, generally once a month is sufficient. The frequency of fertilization in winter should be reduced appropriately, and it is best to choose to use some potassium-rich organic fertilizers , such as decomposed farmyard manure or algae fertilizer , which will help improve the plant's cold resistance. It is not recommended to use high nitrogen fertilizers, as too much nitrogen will cause the plant to grow excessively and increase the burden of cold resistance in winter.

5. Reasonable pruning

Before autumn arrives, proper pruning of tulips will help the plants become healthier and stronger and better withstand the cold of winter.

6. Cover to keep warm

After the temperature drops, you can cover the tulips with warm coverings, using tools such as mulch or flower pot covers, and cover them at night or in cold weather to keep the plants warm.

7. Pest and disease control

During winter, tulips may be threatened by pests and diseases such as aphids, mites and downy mildew. These pests and pathogens may affect the growth of the plants and even cause the tulips to wilt and die. Therefore, during winter maintenance, it is necessary to regularly check the leaves and buds of tulips to detect and take preventive measures in a timely manner.

The above is an introduction to how tulips overwinter in winter. During the overwintering period, you need to pay attention to appropriate relocation. The plant can be placed in a sunny and well-ventilated place for better maintenance.
