Propagation of Ardisia ototomoensis Taton
Ardisia ototomoensis Taton, commonly called the Ototomo Ardisia, is a slow-growing shrub native to the Ototomo Highlands of Papua New Guinea. The plant belongs to the Myrsinaceae family and is known for its attractive foliage and bright red berries. Propagation of this plant is typically done through stem cuttings.

To propagate the plant through stem cuttings, take a cutting that is about 6 inches long and has at least three to four leaves. Remove the bottom set of leaves and dip the cut end in rooting hormone. Plant the cutting in a pot filled with well-draining soil and water thoroughly. Cover the pot with plastic or a clear plastic bag to create a humid environment.
Place the pot in a warm, bright location but away from direct sunlight. Maintain soil moisture by watering when the top layer of soil feels dry to the touch. In approximately four to six weeks, the cutting should have rooted and can be transplanted into a larger pot or into the ground.
