Have any of you guys considered writing a definitive book about growing figs? I looked on Amazon and couldn't find a single one.

It could be published through Storey Publishing or a similar gardening/homesteading specialty publisher. Or self-published!

Maybe some of the proceeds could help fund the Fig Foundation?

I thought the same thing. There should be an ebook :)

Grow Figs Where You Think You Can't   by Steven Biggs  is a very good book for those growing figs in cooler climates.
I think his site is : grow-figs.com

In Russia, there is a book "Varieties of figs", NBS, Yalta, 273 pages. Very rare, small circulation.

Thanks Vladis. Is it in English? Sounds like it would be hard to find, even in Russian.

Some enterprising editor could mine this site (of course, attributions should be made) and could publish the opus right here. I could even see some proceeds going to Jon's NFP.
