On European markets Kalanchoe have been the dominant flowering potted plants for almost a decade. Other Kalanchoe species produced commercially in smaller numbers are K. tomentosa, K. laxiflora, and the former genus Bryophyllum with the species K. daigremontiana and K. tubiflora. Most of the species originate in relatively cool mountain regions in Madagaskar, but some creeping or trailing forms were found in tropical rain forests in southeast Asia and Brazil. Many of these unusual species have been bred into the varieties of our current assortment of Kalanchoe Hybrids. Botanical Kalanchoe species used for hybridization Guidelines for Kalanchoe Production Kalanchoe are propagated from cuttings.
Cuttings usually root within two weeks.
Misting of the cuttings is not recommended, but a light shading cloth during dry and hot periods improves results. Application of rooting hormones shows little or no improvement on root development. Production from seed, once popular, is not commercially interesting anymore. For potting we recommend a peat based, well aerated substrate that drains freely. The peat should be physically stable to maintain its structure throughout the crop cycle.
