I live in the pacific northwest, in Victoria BC (which is zone 8 or zone 9a by some accounts). My available space is only about 6'x7' so after doing alot of research 5 years ago, I planted a Negronne, which is known to be naturally dwarfed. I also planted it in an old clotheswasher basin to further constrain it. It has grown slowly, with a bit of a burst this year (I noticed one big root escaped over the basin rim) and is now just over 5 feet tall. But so far I have been disappointed--there is plenty of fruit on the tree, but only a few brebas, and then only a handful of the second crop ripen gradually before frost. I thought this might improve with time, and indeed the total fruiting has increased with its growth, but even with the really hot summer we had last year I still had such a small percentage of the fruits ripen. I have read that the best fig for the PNW is Desert King which only has a breba, but I avoided it because I know it gets big. 5 years later though, I am sorely tempted to shovel-prune my Negronne and plant a Desert King, in the hopes that I can restrict its size with pruning and the washbasin.
Is there any reason to believe that with time more of the second ripe will mature before frost, or that the breba will increase? Or is there an effective way of pruning to achieve this effect (can't say I've done much pruning since I got it since it was growing so slowly)? If not, is it realistic to think I could keep a desert king under control?
The site gets plenty of sun but is not especially sheltered--it is on the south side of a trellis/arbour but that doesn't protect it much from the wind. It came to me pruned as a single-trunk tree a few feet tall, so I kept it that way.
Thanks for your help.
