Re: [nafex] Lee's suggestion

A few years ago, I put down a couple dozen D. virginiana cuttings. Many of
them survived for several months, but when I dug them up, none had roots.

I also took a couple of kaki plants rooted on virginiana and planted them
sideways in a trench, with a couple feet of the scion underground. After
two or three years, the scions still hadn't rooted.

It seems that persimmons are very reluctant to put out roots from the
above-ground parts. Maybe there is some sort of trick that would coax them
into rooting. It would be very helpful to be able to root cuttings,
because I find that many grafts (even some virginiana on virginiana) fail
at the graft junction after a couple of years.

Here is a reference to the article on tissue culture of persimmons. It
looks simple enough to do at home if you are willing to spend a few hundred
dollars for equipment and supplies.
