When will the first branch of bonsai broken pile be cut off?

The so-called "one support, two releases and three kills" means that after obtaining the pile material, it is necessary to ensure the survival first, and the surviving pile material will be restored without any treatment.

When the branches to be stocked grow to a certain thickness, kill the piles and prune them.

The "three killing piles" mentioned here is not necessarily three years, but depends on the growth rate of tree species. After the conditions for killing piles are met, the specific time for killing piles is generally chosen before germination in early spring. Pay attention to wax sealing or applying plant healing agent to the wound after pile killing to prevent drying, otherwise the branches under the kerf will lose water and die, which will adversely affect the modeling.
