This plant is usually grown for ornamental purposes due to its attractive flowers. If you want to propagate Rondeletia portoricensis Krug & Urban, you can use various methods such as cuttings, seeds, and layering.

Propagation by Cuttings

Propagation through cuttings is one of the easiest and most popular ways to propagate Rondeletia portoricensis Krug & Urban. Select a healthy stem of the plant and cut a portion of it in early spring or late summer. Ensure that the cutting has at least two or three nodes and remove the leaves from the bottom half of the stem. Dip the cut end in rooting hormone and plant it in a well-draining potting mix. Keep the potting soil moist and place a plastic bag over the cutting to maintain humidity. After a few weeks, you will notice new growth, and this means that the plant has rooted. Move the plant to a more significant container or directly to the garden, depending on your preference.

Propagation by Seeds

Rondeletia portoricensis Krug & Urban can also be propagated through seeds. Collect the seeds from the mature fruits of the plant and plant them in a mixture of peat moss and perlite. Cover the seeds with a light layer of the same planting mixture and water thoroughly. To increase the germination rate, you can soak the seeds in water for a few hours before planting. Keep the soil moist and place the planting tray in a warm area with indirect sunlight. The seeds will germinate in about two weeks, and you can then transfer them to more significant pots or to the garden.

Propagation by Layering

Propagation by layering is another method that you can use to propagate Rondeletia portoricensis Krug & Urban. This method involves bending a lower branch of the plant towards the ground while still attached to the parent plant. Ensure that the area of the stem that will come into contact with the soil is free from leaves. Make a small cut or wound in the area where the shoot will come into contact with the soil. Cover the wounded area with soil and secure the branch in place with a stick or stone. Wait for the new roots to develop, which will take a few weeks to several months depending on the conditions. Once rooting has occurred, cut the stem from the parent plant and transplant it to its desired location.

Any of these propagation methods can be used to propagate Rondeletia portoricensis Krug & Urban successfully.
