Purpose of this guide
This article exclusively covers Plumeria propagation by seeds and cuttings. For care of growing Plumeria specimens, including light, fertilization, dormancy, leaves, and pests on an established plant, read the Plumeria care guide.
Propagation by seeds
Plants from seeds grow more slowly, and flowering may appear roughly after 2–4 years or later, depending on genetics, crop density, and nutrient supply. Seeds do not always reproduce the mother plant identically: differences in color and shape may appear.
After pollination, the fruits (follicles) mature and can open in about 8–10 months. To avoid losing the seeds and to monitor maturation, the fruit can be loosely wrapped in a breathable bag tied at the base. Sowing is done warm, in an airy and moist, not saturated, environment.

Propagation by cuttings
Cuttings retain the characteristics of the mother plant and are usually the faster way to a plant that blooms quickly. Harvesting is preferably done in spring. The cutting is usually 20–30 cm. Mature leaves are removed, possibly keeping very young leaves at the tip. The cut is made cleanly with a disinfected tool.

After harvesting, the cutting base can be preventively treated with a contact fungicide and a rooting stimulant. Rooting powder can help but does not guarantee 100% success: hygiene, warmth, ventilation, and careful watering remain decisive.

Callus and rooting
After cutting, the cutting is left in a dry, warm, and ventilated place until the callus forms on the cut area, often up to about two weeks, depending on thickness and conditions. Planting too early in a wet medium is one of the main causes of rot.

Rooting can be done in a light substrate (peat + perlite + sand), but wet organic matter increases the risk of fungus. In practice, a good rooting rate is achieved in perlite or very slightly moist sphagnum, including with a bag around the cutting base, aerated periodically. Sphagnum offers controlled water retention; perlite is inorganic. The rooting material should be moist, not waterlogged.

Planting and after rooting
Insert about 5–7 cm of the cutting base into an aerated, stabilized medium so it doesn’t move. Strong light, warmth, and very careful watering are more important than a pot that is too large. Do not water like a mature-rooted plant until there are reliable signs of rooting: firm new growth and slight resistance to gentle pulling. It is expected that Plumeria will lose leaves after transplanting; recovery is usually quick if roots have formed.
After the plant has taken root
After rooting, follow the complete rules for sun exposure, well-drained substrate, fertilization, winter dormancy, and pests in the Plumeria care guide.
