I actually grow them in containers, however, I know someone else who is far more north than I am, that actually does grow them in the ground, so I know they will grow in the ground here. and the guy claims he doesn't do anything special for them (But I seen the fig trees and they are indeed in the ground.) but the person it is I do not know really, and he seems like a sort of crafty guy, so am not sure I totally believe him when he claims he does 'nothing'...what he may do though I do not know and he didn't tell me....but I did have some of his figs and they were great, he evidently gets a good flush. only one a year though, not two.
