Oh this is a tough one for me, I had fresh one inch, green thick cuttings, and having no idea how to root them, I did what came natural for me. I washed, and sanitized it, then I brushed it with rooting powder where I want the roots to grow and..."Shoved it in dirt"- dirt, I used expensive **organic potting soil ($13 per bag) and aged cow manure, 1 qt cow the rest really good potting soil, drenched it in water, covered with an albertsons bag with a stick. Results -AWESOME roots! I live in Idaho, it gets pretty chilly.. You know the kind that has pretty blue skies, but the wind has a bite sort of thing. I cheated with a LARGE heating mat. I don't have a green house. I live in an itty bitty apt complex for now..
PS: I found awesome soil at feed stores-here in Idaho I bought my soil and manure at Zamzows-- this is where farmers buy feed for their chicken, goats, cowboy country stuff for farms. You'll notice your in the right place when you see a bunch of "live" little chicks for sale inside the store- lol. I am not a die hard organic woman but in my experience, quality of soil really does make a huge difference in my growing climate.
Anyway, my cuttings to full fledge "figlet" took about one month or four weeks of constant....... Checking and rechecking and open and reopen of fresh air.. But yeah work for me all the time. "Shove it dirt" works.
