Moonshine is propagated in the industry by divisions or cuttings, you need to find fresh, tender new growth for best results

Don't know if this is a 'given' in GW world since I'm kinda a novice (you may already do this when you refer to transplanting) -- but I use rooting compound (also called rooting hormone) and that seems to make most ANYTHING root.

I start stuff out in a really small pot so it can establish a root ball quickly. I use potting soil but compact it somewhat, so when I stick in the stem with the compound on it (after making a very slim hole with a stick the same size as stem), the compound stays on the but due to the compaction, there's no air gaps so when I water it, I don't end up 'washing off' the compound into the soil. Does that make sense?

Also, something new I'm trying this year. I make a few little nicks in the part of the stem going into the dirt and put the compound on those too, hoping to generate roots from those areas. Dunno know if it works, but sounds good in principle...LOL

Thanks for the tips. I've now planted 13 new growth cuttings and I've got them on a heat mat. I used some Dragon Rootone on the stems.

I just recently took several yarrow cuttings in different ways and honestly I've found the fastest easiest way is to take a small young (under 6") stem and gently pull it off the root ball. The idea is to get the thinest piece but still keep the white wall that produces the roots. If successful you can place it directly in water, indirect light and in 3 days you should see angle hair like roots that are about 1cm.

Other cutting ways take longer (

Yarrow divides so easily it's not worth the time and bother of rooting cuttings.
