Re Pecans. We're at or near the northern limit for the hardy, smaller varieties. I got a mess of them one year from down along the Ohio. I got some sprouted and have two trees now, been waiting years to have some of my own nuts. Every spring I'm looking for the flowers but nothing yet.......thinking its close to twenty years on now. One day.......
I hate to tell you this, but it's likely that when you finally do get some, your pecans will be useless.
All commercial pecan varieties are grafted from superior wild specimens.
I have two pecan trees in my front yard. One is huge, probably about 100 years old. It is a native, or wild pecan tree, and the meat is impossible to extract from the shell. The meat and the shell is all interwoven together, and when you crack one open, you're left with a mixture of tiny shell and meat fragments and dust that are not worth the effort that it would take to try and separate them. When the tree is having an "on" year, people come by all the time and ask if they can collect the nuts. I say sure, but you're wasting your time. They collect a bunch and never come back. The squirrels do like them though.
My other tree is a much smaller paper-shell variety, specifically a Chocktaw, and is probably about 40 years old. It produces great, big, very easy to shell nuts. Unfortunately, most of the nuts fall prey to disease and insects. I'm doing good if I can salvage 5% of the crop. I'm pretty sure the commercial growers spray the heck out of their trees, even when they are dormant.
