Soil conditions are also crucial. Coffee trees belong to shallow root plants, and the soil is rich in organic matter (with strong fertility), rich in water vapor (and smooth drainage), deep soil layer (usually above lm) and weakly acidic (the soil pH value of coffee planting in Yunnan, China is generally between 5.5 and 6.5). Guatemala, Brazil and Colombia, as well as Hawaii, the Blue Mountains of Jamaica, Java of Indonesia and Yunnan of China can become excellent coffee producing areas, all related to the possession of this kind of volcanic or forest soil. In order to protect the ecological environment as much as possible, it is usually not suitable to plant coffee trees on hilltops and ridges.

When looking for places suitable for coffee trees, experienced coffee gardeners often look at the growth status of local tropical cash crops such as mangoes, bananas and olives, as well as "indicator plants" such as mulberry and acacia trees. In addition, as the concepts of "health, environmental protection, and organic" are gradually taking root in the hearts of the people, we need to detect the concentration of pollutants in the soil. Most of the coffee producing areas in the world are located in the tropics between the Tropic of Cancer and the Tropic of Cancer. We call them "coffee belts" or Coffee Belt or Coffee Zone in English. As a tropical cash crop, coffee trees grow in coffee belts with excellent climatic conditions, where the sun shines all the year round, has abundant calories and sufficient Rain Water, and the annual average temperature is above 20 degrees Celsius. However, high temperature, humidity and strong light can not be tolerated by any variety of coffee trees. For example, some Arabica coffee trees are not resistant to high temperature and humidity, and are often planted at higher elevations. Shade treatment is also needed, hence the name "Rainforest Coffee" and "Shade planting Coffee"
