Christy, I've only tried powdered hormone (once, before I joined the Forum). Results were so dismal I never tried again. I know some use Clonex and other types of gel hormones to great result, but I've shied away. The larger cuttings are pretty reliable without much effort. Put in sphag bin until rooted, move to cup or pot up. When it comes to little cuttings--particularly those mailed and/or stored, it's just a crapshoot for me. I was hoping to wait for spring to root them, but afraid those little greenies might not fare well in the fridge. I put one in a little bin of perlite today just to see what will happen. The rest I'll hold off a little longer. Based on Pete's remark, the dry air of indoors during winter really makes the little ones a chore to grow. Keep'em covered and they might stay too wet, air 'em out and they dry up.
I know we can't win 'em all, but it sure stinks to lose any of them. Hopefully I've become better at 'reading' cuttings and might have a little more experience on my side going forward.
