Hi Danny! I've seen that method, loved it, and tried it on a bunch of green softwood cuttings. Every one rotted, and I had them inside in indirect light, too. Should have used Sphangum moss instead of potting soil, I guess.
I'm getting 100% success in just plain damp Sphangum in a baggie with a paper towel changed every couple days (when it gets too damp) to absorb moisture. Been keeping them in the dark until I see roots, then potting them up and putting them in the vineyard shade canopy to get used to dappled sun and weather. Most still rooting have leaves now, but no roots. Most have root initials though, and no signs of rot at all after 2 weeks.
Chris, you are right about trial and error! It's good to read all the methods and I'm thankful for whoever posted here that Sphangum moss inhibits mold. Wish I could have my rotted cuttings back to try again with the way that I have found works best for me.
On another note, it's nice to know that we all have our little failures! Looking forward to my UC Davis order and dormant cuttings promised from several of you!
