When is Slaughter tapping done in rubber?

Slaughter tapping is done in rubber before replacing the plantation.
Slaughter tapping is an obsolete method of extracting large quantities of natural latex from rubber trees in a forest environment.
The term slaughter tapping is used to indicate all-out bleeding of rubber trees to obtain maximum yield without regard to the health or longevity of trees. It is done one or two years before replanting or replacing the crop.
