I took the stem tip cuttings about 6 weeks ago applied rooting hormone and placed the cuttings in moist sand in a plastic cup. I kept the cuttings in a humid environment for the duration and kept them watered. I checked the asclepias cuttings periodically for rooting by giving them a gentle tug. If I didn't feel resistance I left them alone.
Yesterday I was able to pot up three of three asclepias cuttings. Now I'll have to find some of my orange butterfly weed to give it a try!
It's always fun to make more plants through plant propagation!
