Hi lvman,
Welcome to the forum !
How long are you willing to wait to get figs ? Or, could you afford to buy a tree of significant size ?
I mean, could you buy a 3'/4' tree ? No cuttings .
If you go through grafting, you may have to wait one or two years - That is if your grafts are successful at first shot ... If not, add more years ...
You'll do as you want, but this is my way :
Choose a tree known to be productive. What is such a tree ? :
A. A tree from your neighborhood that you know produces fruits as desired.
B. A tree from a nursery with a name on the tag . Some may say, pray for the tag to be correct ... But that's another topic.
Dig your current trees out. I see lots of nice strong leaves on them, and this for me means that someone (you,wife,gardener) is giving good cares to those trees.
In 3 years, a figtree should show production, or something is wrong ... more than likely a bad strain.
Now as for the choice ... You have a lot, and it all depends on your taste-buds.
In your zone, you could grow BlackMission, mount etna types (Hardy chicago...), Adriatic types (Dalmatie ... ) , Honey types (Italian Honey, Pingo de Mel ... ), Brownturkey ... .
I would make sure to get a strain of the common type. Don't risk a smyrna type if you're not sure that you have the fig-wasp.
Buy a decent sized tree (price around 20 or 30 bucks normally), and you'll get fruits quickly . Plant them in the right place !
Good luck !
