Name: Marica Northern Ca mountains 4000' (Zone 7b)
sy I use Dyna gro products for my Adeniums KLN is their root hormone. It takes so little to use. It is like 1/4tsp per gallon. I would think any root hormone would work. I use to use root tone. I have never had a problem with the smell.
I also root just two sections not a whole stem.
