Thanks for the replies, @BlueBerry and @Barkslip. I had two each of Oconee and Caddo (type 1) and Lakota and Zinner (type 2). Five or six of them died after the first year and the rest were gone the next. We dug deep holes for them, and they had a decent taproot but sparse feeder roots.
Don’t know exactly what happened, it seemed like the grafts didn’t do so well, or maybe it was the lack of roots that did them in. Or maybe they were the wrong varieties for our location.
In comparison, I bought a bare root pecan at a local farm supply store two years ago for my Mom and it has flourished since I planted it. But it had great small roots and a big taproot. But this was in OK, too, so much different climate.
In the future if I got any more, it’d be potted ones from Nolin River, and get the ones Dax and Darrel has suggested- Hark, Mullahy, Kanza, etc on Major rootstock.
Curious Dax, do you sell your grafted pecans, and if so, what do you charge? You can PM me if you wish. Thanks.
