How does outdoor passion fruit survive the winter? What is the minimum temperature for wintering?

1. Wintering methods outdoors

1. Build a shed: If you want to let passion fruit spend the winter outdoors, you can use plastic film to build a greenhouse. Although this is a bit troublesome, it is a better method to keep out the cold. On sunny days, it needs to be opened for ventilation and light, and covered at night.

2. Wrapping: When it is cold in winter, you can wrap the roots and trunk of the passion fruit with plastic cloth. And you should water it less and let it see more sunlight.

3. Sprinkle lime: When growing plants in pots, the general way to keep them warm is to sprinkle some lime in the pots. You can also use weeds, films, etc. to keep out the cold. If it is overwintering in the third year, you can cut off some old branches, but it will not have much impact if you don't cut them.

2. Wintering Temperature

The temperature suitable for its growth is around 20℃~30℃. Under normal circumstances, as long as the wintering temperature is above 0℃, it can survive the winter smoothly. But if the temperature is below -2℃, it will be difficult for it to resist the invasion of cold air and it is very likely to be frozen. If it stays in a low temperature environment for a long time, it may freeze to death. Generally, it is easy to grow potted plants over the winter because they can be brought indoors when the temperature drops.
