I don't overthink it either. I break off a Brug (Charles Grimaldi) sprout from the base of my larger plant and stick it immediately into a vase or bucket of water. I have also taken the starters and stuck them in potting soil and kept that moist, but not muddy, until they root. In the Spring you can put them in a shadier location to root, but usually in the Fall I will set them in a sunnier spot (if, and until, there is a threat of temps below 50 at night....I live in South Texas.) You can tell they have rooted in the soil mix because at first the leaves will fall off the cutting, then about 3 weeks or so the tiny little new leaves will begin to pop out from the branch. Good Luck!!

I haven't done it myself but the person I got my cuttings from, she probably had them about 75% of the way in water for several months. Though strangely, roots were growing more from the bottom than from the other areas along the stem, even though they had some nodes in water.

As a result, although most of the cutting was in water for a few months, what I actually covered was maybe just the bottom 25% of the cutting where the roots had grown. The cuttings fared well and are now nice plants on their own.

I change the water every 2-3 days. That's it.
