    I received a few plants that are pretty small, about 1 inch across about 3 weeks ago, and I have a leaf cutting that is about 2 months old now, also a little bigger than an inch across. They are Filiformis, Madagascariensis Botswana, Intermedia, and the leaf cutting is a Rotundifolia. Do they need dormancy this year? Thanks.

    The D. filiformis will go dormant as the day length shortens. Probably the D. intermedia and D. rotundifolia as well if they are temperate forms of the species (likely). This is a result of daylength, and if you keep a natural photoperiod the plants will go dormant without assist from you. Once dormant, plants should be kept just above freezing for 2-3 months in a barely damp mix and in good air circulation. Of these, D. intermedia is the most difficult to overwinter, esp. if kept wet. The leaf cutting will likely continue to grow if kept on a longday photoperiod.

    D. madagascariensis is a sub tropical, and although it occasionally dies back, it will do this on its own. Never attempt to encourage dormancy other than by modifying your photoperiod. Keep the D. magagascariensis in the same conditions as in active growth and it will eventually regenerate and grow from the roots. Juvenille examples rarely go dormant.
