Hi! Thanx for the nice comments. I did not make a video of taking the leaf cuttings. I will, when I get a tripod for my camera (or grow a third arm;-))). But there is really not much to be camcorded. I simply cut the leaf off as close to the base as possible, using a pair of scissors. The reason why I didnt use leaf pullings is, that some leaves are really stubborn to be torn off of the mother plant and you might accidentally hurt the plant severely (which, in case of more precious species such as graminifolia, roraimae or camporupestris might be lethal). Using leaf pullings instead of leaf cuttings does not amke any difference anyways (unless you are propagating petiolaris group).
Now I noticed the new plants form much earlier and in bigger numbers on older, almost dying leaves. Using young fresh leaves causes slower growth (if any), and the plants are fewer (which is kinda weird, since on TC it is the other way around!)
Now I do not use water method. Although it works great for propagation rate, the plants are etiolated and seem kind of weak and take longer to adjust to substrate (With some 'weedy sundews' there is not much difference).
I use paper tissue/peat method, which has 2 stages. I put some inch thick layer of peat/sand (50/50) mix inside a plastic food container. Then I cover it with thick paper tissue and let it soak with water. Then I simply place the cuttings on the surface and cover it with food foil to ensure almost 100%humidity.
Then I keep the tray in a shadowy area (I noticed some species dont form buds in light well). The temps are kept quite cold, 13-17night/18-22day. After about a month, first growth appears.
Then the second stage commences, I remove the paper tissue and place the unrooted plantlets with leaf residue directly onto the substrate, place it in warmer area that gets enough light. Once the plantlets root, they will start growing really fast (especially when fed properly).
When they are big enough I repot them and place in a terrarium with other plants.
...and I agree, d ascendens is very prolific under these conditions. I never tried villosa, but will try graomogolensis and other species soon:-) GOOD LUCK EVERYBODY!
