If you can, cut at least 12-inch pieces for a better chance at rooting. As you can see, I was not able to do that but it’s ok if it’s less than 12 inches. These are all just ideal-scenario plumeria propagation tips. 😉
Use a sharp blade like pruning shears or a knife. To prevent spreading potential disease to each cutting and throughout the plant, disinfect the blade between each cut with rubbing alcohol (at least 70% isopropyl alcohol).
When you make a cutting on a plumeria plant, there will be a white sap. This is normal, not a disease. Yay! It can cause irritation to sensitive skin so it is wise to wear gloves for your protection. I didn’t realize that when I made my cuttings and my hands were fine – but I didn’t touch the sap, so be careful with either method.
