Timo,
Pons sell them for 20 euros and I don't mind helping out someone if they are willing to pay for the cutting, shipping and packaging costs etc.
I got 3 trees growing nicely one grafted and 2 rooted. Last year I bought 12 BNR cuttings for a friend and for me. I rooted two and one died. This year I bought three, I grafted one half and rooted the other half. Two cuttings again went to a friend. The grafted one is growing well. And yes it's a slow grower but with a well drained mix like 5:1:1 plus lots of other stuff and dynagro foliage pro, I'm hoping for better results . I hope this clear your doubts.
P.S. Black Madeira is supposedly a slow grower but it grew 5ft in one season and produced Figs for me. Cuttings from Figaholics.
Ben,
Absolutely, you got it.
