A little bit of a bump, but threads like this are what I love about reading these forums.
Anyway, all the way down here in 10b Miami, nearly every single one of my trees defoliated and went dormant this winter 2014-15. I don't think temperatures have dropped below 50F, with the daytime temperatures reaching into the 60s - 80s. I think last night was the coldest it's been (so far) since Jan 2014 and it was only ~52F at 3 am.
The only trees of mine that didn't defoliate were one new Excel and one new 143-36 but their existing buds didn't develop into anything and they didn't put out any new growth until about two weeks ago, when nearly all of the rest of my trees began to break dormancy. (LSU SB, Brown Turkey, Kadota, and Hollier being reaaaally happy to be awake. In fact, only my RDB woke up a week or so later than the rest of them.)
Also, idk if this really matters when it comes to dormancy, but if you're curious, all of my fig trees are in pots. However, in my neighborhood, there are a few in-ground fig trees, all of which went dormant and broke dormancy in sync with my potted trees.
I should note that 10b accumulated zero chill hours during the Winter of 2013- 2014 and I got fruit from all of my trees, even ones I'd started from cuttings seven months before harvest (RDB & JHA.) Both varieties grew about 4 feet. Not only that, but my older Texas Blue Giant and Kadota matured and produced better quality figs with a larger crop.
In Winter '13-'14, the coldest temperatures ranged from the ~38F at night to the ~mid 60s during the day, and that really only lasted a day or two before it started going back to 60s at night and 70s during the day.
As for whether sufficient chill hours are necessary for optimal fruit quality, I don't have that answer. Does anyone else from this far south have any input?
