I have been growing and selling figs, for about 12 years or so. I can’t remember off hand, how many we have, in ground and also in pots. The potted figs, range from one gallon to 7 gallon pots. Also, in ground figs are planted in two different spots.
The main thing that we have discovered here, is that it is not just winter cold that kills figs, but late winter, early spring sun, that kills figs, more then cold. Figs planted next to our heated basement wall, have always been killed to the ground. But, the same figs just three feet away, have been able to keep two year old growth alive from year to year. As long as the growth is no higher then 8"to 12", from the ground.
As to heavy bearing figs in pots. The heaviest bearing fig we have is Hanc’s English Brown Turkey. It is in a half full, 5 gallon pot. It also, been has been identified by Herman, as Southern Brown turkey. If I could only have one potted fig, it would be this fig.
It is not only easy to grow, very cold hardy, heavy bearing, but also very early. About 7 to 10 days earlier then the average early figs, such as Ronde de Bordeaux, and Marseille Black VS.
I have a list of the figs we have been testing for cold hardiness, the past 12 years, or so, here in our 5b/6a location in Connecticut.
I was out sick for the last two years and the list needs to be updated. But, I think it will still point new growers in the right direction.
If any one would like for me to send them the list, simply email me direct at: robertcharper@ gmail.com
