you can take small basal cuttting as small as the pot on the right.
My example on the bigger Basal cutting. Put into rooting on 07.07.2007
checking and rooted as at 24.08.2007
old leaves were still crappy.
showing the developing new leaf from 10.9.2007 to 29.9.2007. Old leaves recovered and look fresh and healthy.
Now i had another red ampullaria. I will post once it bears pitchers.
