So, I have a D. multifida 'extrema' plant that has never flowered for me. It's already survived one winter under lights, but I'm getting nervous only having one, so I want to start at least one cutting in a terrarium as a backup.
I'm curious as to the best way to do this. I know a few people have had great success with floating them in water. What are the specifics of this? Does the water need to be changed periodically, or just topped off as it evaporates. Once you see strikes, do you just lay the leaf on suitable media?
What about just laying the entire leaf or pieces thereof on media to begin with? Do you include the leaf blades, or just the petiole? Do older leaves that are beginning to lose their dew work as well as freshly unfurled leaves?
Sorry for asking so many questions that are probably common knowledge, but all of my experience with plant cuttings so far have been strictly with fresh flower stalks, laid on damp media with the ends lightly covered.
