Olive trees first grew in the Mediterranean coast of southern Europe, and then were introduced to China. They were planted in 15 provinces from the south of the Yangtze River valley to Guangdong and Guangxi, with Hubei, Sichuan, Yunnan, Guizhou, Shaanxi and other provinces as the largest, and also cultivated in Japan (Nagasaki, Okinawa) and Malay Peninsula. The price of each seedling ranged from 130 to 220.

Olive tree growing place

Wild varieties of olive trees are distributed in areas below1300m above sea level, or cultivated in gardens and villages. They are widely distributed in China, mainly in the south of the Yangtze River, among which Hubei, Sichuan, Yunnan, Guizhou and Shaanxi provinces are the most planted.

Growth characteristics of olive trees

Olives like warm environment, and only when the temperature is high during the growing period will the yield increase. The annual average temperature is above 20 degrees, and the areas without freezing damage are most suitable for winter growth. It has certain cold tolerance, and can endure the low temperature of minus 3 degrees for a short time, but it will cause serious freezing damage when it is lower than 4 degrees, and the rainfall is best at1200-1400 mm.

The growing environment of olive trees

The flowering time of olive trees is from April to May, and the fruit ripening time is 10- 12, generally 1 10 to March of the following year. When three-quarters of the fruits change from green to purple or close to black, it proves that three-quarters of the fruits are ripe and can be picked at any time.

Olive trees have serious requirements for soil and are suitable for planting in neutral and slightly alkaline soil. They are very picky about the content of water and trace elements in the soil. It is generally believed that olive trees need a temperature below 0 degrees to achieve the requirements of normal flowering and fruiting, and the lowest temperature of MINUS 3 degrees is most suitable for flower bud differentiation, and the lowest temperature in winter should not be lower than 0 degrees.

Olive trees are drought-tolerant, but they still need to be watered in time to keep the soil moist, and the air humidity can be kept between 40% and 65%. It likes sunshine and is a strong positive tree species. If the light is insufficient, it will affect the development of fruits and trees.
