How to deal with the roots of old piles

The roots of old piles that grow normally do not need to be treated. If the old pile has rotten roots, you need to cut off all the rotten black places with scissors. In addition, if it is an old pile that has just been dug back, the main root should be properly cut short and a certain number of relatively messy lateral roots should be cut off before it is put into the basin. This can prevent them from growing together in the soil and hinder the growth of other roots.
