Honestly, keep them warm in bright light on top of dirt like any other cutting I would think. I've been trying to root 2 red pups for months now to no avail. Good luck to ya!

Hard?? No. I wouldn't consider rooting anything to be that hard, as it requires minimum actual effort. Tricky is your word!

I don't think it would require any special effort, just the regular stick it on the soil surface and wait. I wouldn't put it in extremely bright light, but keep it warm.

I have never done this, but I really want to add a deep purple gymno to my collection.

p&s, if it's successful, I can send one your way. Or if you like, I can send an unrooted pup to you.

Thanks for the offer, I really appreciate it :)

It's tempting, but I'll have to decline.

Maybe try some rooting powder if they're difficult to root :)
