Dr. Mnners, no I have never actually produced a tree from a leaf cutting. Here is a recent letter I received from Laaz's friend about rooting citrus leaves:
"""<<the method is exactly the same as you root a budstick.
and as to my experience you can root all citrus, which can be rooted from
their budsticks.
easiest are the Citrons (C. medica) and lemons (C. limon)
take 100 leaves, you will have 20 rooted
But under my conditions it was a "very long way", and at the end I was not
patient enough, so I had only the roots, but no new plants growing.
So it was just for fun and I did as an experiment,
what already the famous J.Ch.Volkamer described in his book in year 1714."""
As far as I see it producing citrus from leaf cuttings, has a value only as a fun experiment. There are too many other methods that work better and faster. When one produces a plantlet from an African Violet leaf, it takes about 4-6 weeks to root the leaf, and then another one to 2 months to actually get a plantlet, depending heat. In your experience, after you obtained roots from a citrus leaf, what was the LONGEST TIME that you continued to grow the rooted leaf in an effort to get a plantlet? I guess I'm asking, will persistance pay off in the loooooong run? - Millet
