These are some of my green cuttings. I'm trying something new - putting the cuttings horizontally into small plastic trays (no drainage) in moist mix. Just barely damp, not wet at all. Then putting these into bins that get aired periodically. I started with the mix being half perlite, half potting soil then switched to 100% potting soil because the white perlite flecks were making it difficult to see any roots forming. Sphagnum moss would work - I just don't have any.
When observable roots begin to form, the cutting goes directly into opaque, black plant bands for further growth in damp half perlite, half potting soil. I do not water them now, but do mist them. They go into a humidity bin covered with clearish plastic, that gets bright window light, but zero direct sun.
The first is a cutting of Scott's Black with a green bud at the top, and very baby roots forming at the bottom.
The second photo is the bottom of that cutting, showing the tiny roots just barely emerging. They are not at the very bottom, but about a mm up.
The next photo is of the bins with two cuttings, with two green buds barely showing. The cuttings are horizontal and totally covered - with only the buds allowed to peek through. You can see moisture from misting on the edge of the tray - don't want everything to dry too much when I'm working on them.
Another bin with two more cuttings with leaves more advanced. No roots yet on these, so no bands. But they get enough light and humidity so they can grow.
Last photo is 4 cuttings that showed small roots transferred into plant bands, and beginning to leaf. The two on the right are Scott's black. Don't remember what the other two are. The mix is ligthly put in, then lightly tapped in so it settles. Still not watered, but put into humidity chambers and misted. Still no direct sun, but good window light.
