You can take cuttings, put in glass of water, and set in window to root. It will take awhile, and results aren't as reliable, but it can be done. Lightly, lightly skin off the outer layer on your cutting, about an inch up from the bottom. Be sure to not leave alot of leaf on your cuttings, minimal amount of green is enough to give this rootless cutting what it needs. Change the water DAILY. It needs oxygen and cant be stale. Some people even use an aquarium bubbler in the water. Watch for little white nubs to appear in about 10-14 days. Let us know how it works. Good luck
