Stem cuttings

Stem cuttings are a simple and effective way to propagate Tabernaemontana thonneri T.Durand & De Wild. ex Stapf. The best time to take cuttings is in the spring or early summer when the plant is actively growing. Select healthy, young stems and cut them into 6-8 inch sections using a clean, sharp pair of pruning shears.

Air layering

Air layering is another propagation method that can be used for Tabernaemontana thonneri T.Durand & De Wild. ex Stapf. This method involves encouraging roots to grow on a stem that is still attached to the parent plant. Select a healthy stem and make a small cut just below a leaf node. Wrap a damp sphagnum moss around the cut and cover it with plastic wrap to hold the moisture in. After a few weeks, roots should begin to form in the moss. Cut the stem below the new roots and transplant the newly rooted plant into a pot or the ground.

Both stem cuttings and air layering can be effective ways to propagate Tabernaemontana thonneri T.Durand & De Wild. ex Stapf. With the proper care and attention, you can quickly establish new plants and enjoy the beauty of this ornamental shrub or small tree.
