Can trumpet creeper overwinter outdoors?

Trumpet creeper is a perennial deciduous vine that likes to grow in warm, humid areas with mild climates and is suitable for planting in tropical and subtropical regions. So can trumpet creeper overwinter outdoors?

1. Cold resistance

Trumpet creeper is a flower with strong cold resistance. The Chinese trumpet creeper can survive temperatures as low as minus 23°C, while the American trumpet creeper is even more cold-resistant and can tolerate temperatures as low as minus 34°C. Therefore, trumpet creeper can basically survive the winter easily in most parts of my country.

2. Open-air wintering conditions

The shrub can overwinter in the open air. It has a strong cold resistance and can survive the winter without being brought indoors. Whether in the north or the south, trumpet creeper can overwinter in the open field. In the cold northern regions, it only needs to be pruned and covered with a layer of straw to keep it warm.

3. Wintering advice in the north

In the cold northern regions, trumpet creeper can be protected from the cold by pruning, covering with straw and other measures. Potted trumpet creepers should be brought indoors for the winter as much as possible, while ground-planted trumpet creepers can overwinter outdoors.

4. Winter maintenance

In winter, the trumpet creeper needs to control the amount of water, stop fertilizing, and ensure sufficient sunlight to help it survive the winter safely.

5. Temperature requirements

Trumpet creeper likes a warm environment, and the most suitable growth temperature is 10-28 degrees. When growing it in the north, it is best to place it in a warm indoor environment and avoid placing it outdoors, otherwise the plant may be frozen to death.

To sum up, trumpet creeper can overwinter in the open air, especially in the southern regions. In northern regions, if winter temperatures are very low, some protective measures may be needed, such as covering with straw or moving indoors for the winter.
