amorph leaf cuttings/tc

I still haven't tried titanum, but there are several species I routinely propagate by leaf cuttings. Of those, I have also not seen any difference between cuttings taken soon after leaf emergence or later, with one exception: if I wait until the plant is near dormancy again, they don't ever seem to take. I don't really find this surprising. But right up until you see that characteristic very slight change in appearance that signals oncoming dormancy, yes. I haven't kept any records, but I'd say that across the few species I've tried I'm getting about 60% to take. As to what I mean by that, I take a set of relatively small cuttings (to minimize leaf surface lost by the donor) all at once, either from a single plant or set of clones, which all tend to stay in synch. Having given it/them one setback, I don't take any more during that growth cycle. So, I wind up with 3 of 5, 4 of 6, etc. That's with no mist but relatively high (65-70%) humidity (no pun intended). It's been a very easy and trouble free method for me - I put them on shady shelves in the greenhouse and tend to forget about them for weeks at a time. This discussion has gotten me interested again. I think I'll try a few new species tonight. Steve -- Steve Marak -- samarak@arachne.uark.edu

Thanks for the response.
