Hi Folks. 4 years ago I bought 5 Brown Turkey figs and 7 Chicago Hardy figs at Lowes and planted them. I tell you they were from Lowes because I now know the risks of Big-Box trees, especially mislabeling, so I wanted you to bear that in mind as you think about my problem.
I planted my figs in all different locations, spread all over my 8 acre property. So they get some slightly different soils and drainage, but all are in full sun. At every location I planted a Brown Turkey (BT) I also planted a Chicago Hardy (CH). Over the last 4 years, all plants have grown amazingly well and are now almost all over 6 foot tall and 5 ft wide and bushy and green and healthy in every way you can see. They both produce an amazing volume of baby Figs as spring turns into to summer. So in almost every way, all 12 of my figs appear to have done incredibly well and are healthy looking.
But each year the problem comes in late August/early Sept. The figs on the CH trees start to get much bigger and then turn purple and ripen. They get big, sweet, and are just wonderful. The BT trees just never do ripen their fruit. At the VERY end of the year, just about the time frost hits (this year it was almost DECEMBER! but usually its mid Nov) you can find maybe 3-4 figs on each bt tree that have turned a light purple, but they don't get bigger as the ripen they way my CH figs do. These "sort-of-ripe" ones are fairly sweet, but they are dry inside and just look unripe.
I live in Northern Middle Tennessee, right on the TN/KY border. I'm right on the line of zone 6b and 7a. I am pretty sure BT figs should be able to ripen in my zone, right? FYI, I usually don't winterize my trees but they usually do fine and while I had 1/2 of them freeze to the ground on year 2, they all came back and now they are all about the same size. We had an extremely mild winter last year with no frost damage at all and my BT trees started growing in March and never stopped. Also FYI, I usually throw about 2 handfulls of 15-15-15 around the base of my figs once time a year, usually in early may. Last year I withheld it from 2 figs to see if it would matter and the only difference was they didn't grow as much as the others. But their figs didn't ripen.
Has anyone else had this problem? Is there anything I could be doing that might prevent my BT figs from maturing and ripening? AM I right in understanding that BT should ripen fine in zone 6b/7a? If they were mislabeled, could it be some other variety that can't ripen in zone 7a? I'd have thought almost any fig could ripen here if it wasn't winter killed back. And while Lowe's certainly might have mislabeled, I wouldn't think many varieties could withstatnd 4 winters with almost no die back, and I wouldn't think Lowes would have many rare figs for sale in bulk like these. But that's all guess work. I'd just like to know why these trees full of baby figs never ripen, even when (THIS YEAR) the last frost was in MARCH and the first frost was in December!!!!!!! Both are admittedly rare, but this year these figs had more than 8 months of growing time!!! And still didn't ripen at all. What gives? Thanks folks!
