We rooted Popcorn Plant ( Cassia didymobotrya) cuttings in mid- February, using a rooting hormone, Hormex powder, last year in our retail greenhouse. The majority of them rooted successfully, and even flowered, while in 4.5 " pots, throughout the summer in the greenhouse. They were stem tip cuttings, propagated in Baccto soil, and kept moist while rooting. Bottom heat was used underneath the propagating table. The air temperature was around 60 F during the day, and 50 F at night, while they were rooting. The leaves would droop during the season when the soil was too dry, which happened many times when greenhouse temperatures would range from 90 F to 100 F.
