Detailed Explanation of the Reasons and Methods for Root Cutting in Mango Trees

Many growers only know about pruning mango trees, such as pruning during the growing season, spring pruning or winter pruning, but in fact, for plants that do not bear fruit, root cutting can also be carried out. Root cutting can help mango grow and develop better and help increase yield. Let's take a look at the reasons and methods for mango root cutting with the editor below.

1. Reasons for Mango Root Cutting

When a mango tree does not bear fruit and its vigor declines, it generally starts with the root system. Root pruning and renewal have the same meaning as pruning the aboveground parts. Root cutting is pruning the plant's root system, just like heading back on the tree. After root cutting, a large number of new roots will grow from the wound. One root will become multiple roots, and old roots will also become new roots. The number of roots increases, so the plant's ability to absorb nutrients will naturally be strengthened. The mango root system is graded. The original old roots will evolve into transport roots, whose main function is to transport nutrients, while the roots newly grown after root cutting are called growth roots. Growth roots are the mother roots for absorption and will continuously grow absorption roots. The lifespan of absorption roots is relatively short. Only when growth roots continuously produce absorption roots will the plant not suffer from insufficient nutrients.

2. Purpose of Root Cutting

Mango is a deep-rooted crop with well-developed main roots and fewer lateral roots. Root cutting is often used as one of the methods to control the vegetative growth of branches and shoots. After root cutting, it is beneficial to fruit development. The purpose of root cutting is to reduce the root system's absorption of water and nutrients and promote root growth.

3. Root Cutting Methods

In winter, combined with deep plowing and soil improvement, dig a ring trench about 60 cm deep and 30 cm wide vertically below the tree canopy, cut off the thick roots in the lower layer, expose them to the sun for 5-6 days, then apply decomposed organic fertilizer and cover with topsoil. At the same time, combine with overall cultivation and shallow tillage of 20 cm to cut off the absorption roots in the surface soil, weaken the root system's transport of water and nutrients, increase the sap concentration of the tree, favor the accumulation of nutrients in the aboveground parts, and promote flower bud differentiation. After root cutting in mango, appropriate fertilization and loosening of the soil are needed, which is beneficial to the development of horizontal roots, but excessive water should not be added, so that the root system can accumulate more nutrients.
