Growing environment of avocado:

The average precipitation in the country of origin is generally above 1, 200mm, which is obvious in dry and wet seasons, but the average annual precipitation is above 1, 000 mm. It can grow normally in areas that are not particularly dry or evenly distributed in rainy seasons, and the best precipitation is 1, 500-2,000 mm. High temperature and drought are extremely unfavorable to the growth of avocados, which is easy.

Avocado is a shallow-rooted tree species with fragile branches and poor wind resistance, so it is advisable to choose shelter from the wind. It has wide adaptability to soil, but it is more suitable for sandy loam with good drainage, underground water level below 2 meters, soil depth above 1 meter and deep soil layer. Avocado is not conducive to the growth of low-lying land with poor drainage or soil with high groundwater level, and it is easy to be infected with root rot.
