Propagation of Oxyanthus laurentii De Wild.

Oxyanthus laurentii De Wild. or commonly called Gabon Bitter Herb is a perennial herb found mostly in tropical Africa. Propagation of this plant can be done through various techniques including:

Division:

Division is the most common method of propagation used for Oxyanthus laurentii De Wild. In this method, the mature plant is dug up and the root ball is carefully divided into smaller sections.
