1、 Life span

Passion fruit is a perennial fruit tree. Its life span is about 20 years, but its economic life span will be shorter, about 8 ~ 10 years. However, the life span may be shorter in the process of planting, because its growth is easily shortened by diseases or weather. Most of the time, the economic life is 1-3 years

2、 Winter methods in South China

1. Temperature: when cultivating passion fruit in the south, the temperature should be controlled above 0 ℃ and not below 0 ℃. If it is too low, it will be frozen. If the outdoor temperature has dropped below 0 ℃, move to a slightly warmer location. If you can't move the position, you can build a greenhouse for it, so that it can survive the winter to a great extent

2. Less water: it needs a small amount of water during the winter. Remember not to water it when it is not dry. It is usually unnecessary to water it in winter. When watering, the water temperature should not be too low, because the climate in winter is very cold. If the root system is stimulated by low water temperature, it is easy to freeze it

3. Antifreeze: if the climate is very cold, you can sprinkle some lime appropriately, or trim it in winter. Generally, most of the branches are cut off and then buried in the soil for the winter
