Soil is the place where tea trees take root all year round. The quality of soil texture, nutrient content, pH and soil layer thickness all have a greater impact on the growth of tea trees.

The soil texture suitable for the growth of tea trees is generally sandy loam. Because sandy loam soil is conducive to water and fertilizer retention, good ventilation. Soils that are too sandy or too sticky are not ideal.

The pH of the soil suitable for the growth of tea trees is pH 4.5 to 5.5, and pH 4.0 to 6.5 can grow, but the alkaline soil with pH value greater than 7 is not conducive to the growth of tea trees. Therefore, it is absolutely impossible to grow tea in the saline-alkali soil in the north.

The thickness of the soil suitable for the growth of tea trees should not be less than 60 cm. Because the main root of a tea tree can usually grow to more than 1 meter, and the lateral roots should be stretched around, the ability to absorb water and fertilizer depends on the development of the root system, so the deep soil is conducive to the growth of the tea tree.

The nutrient status of the soil is also an important condition that determines the growth of tea trees. Tea trees need dozens of nutrients such as nitrogen, phosphorus, potassium, calcium, magnesium, iron, etc. in the growth process. Good soil basic nutrient conditions, coupled with timely fertilization and cultivation management, can fully meet the nutrient needs of tea trees.

Terrain conditions sometimes also affect the growth of tea trees. The terrain is gentle and the slope is not conducive to soil and water conservation and the growth of tea trees. When the slope is large, it is necessary to reclaim high-level tea gardens, which is conducive to soil and water conservation.
