Frangipani, also known as Plumeria, is in the family of Apocynaceae. It is one of the easiest plants to grow from cuttings. In fact, too much care can actually kill it. Frangipani is a tropical plant, so cuttings will root best during the warmer months, especially in zones 8 and lower. In tropical and subtropical areas of the U.S., frangipani cuttings can be grown year round. Even novice gardeners should not have problems planting frangipani cuttings.
Wait until frost or freeze no longer threaten the region before pruning the parent frangipani tree to take the cutting.
Cut off the branch of the frangipani you will root and make it 8 inches to several feet long.
Allow the cutting to heal for one week before planting it, and set the cutting in a warm, dry area. Do not plant the cutting as soon as it is cut.
Select a container with drain holes that is large enough to accommodate the size of the cutting. Use a one-gallon container for single-branched cuttings up to approximately 15 inches long. Use a three-gallon container for larger cuttings.
Fill the container with a lightweight, organic potting mix that drains well. Do not use a heavy potting medium that retains water or the cutting will rot and die.
Dip the end of the frangipani cutting into rooting hormone and shake off any excess. Dig a hole in the soil approximately as deep as 1/3 of the cutting's length. Place the cutting in the hole and pack the soil firmly around it so that it stands upright on its own.
Water the cutting thoroughly. Test the soil by sticking your finger deep into it. If the soil is dry, water the cutting again. Do not keep the cutting in soil that is constantly wet.
Place the container in a warm area that receives full to partial sun for several hours a day to help the plant to form roots.
