I thought sinse most people on this forum like to cook/eat, this might be of interest to you and all.
I love pecans so about 10 years or so ago I did a complete search on the subject of getting trees to grow in Maryland.
I found basically all my information (no one else knew anything) from Texas University, I wrote to them and received responses and continuing help from there college Dean.
He advised that there latest research had come up with 2 varietys that were promising for the northern regions that had been developed in Texas. One is the polinator for the other, so one would have to have at least one of each variety.
The two trees are "Pawnee and Kiowa".
I purchased and planted the 2 trees, but I failed to take into consideration the prevailing winds and had very few nuts. They were planted about 80 yards apart. So I bought another and planted it closser. Last year is the first year the older tree produced nuts due to the closer polinator. I only got about 5 or 6 lbs of pecans ( about 8 lbs of squirrels though).
Thise were the nuts used in the Brownie Recipe .
Just thought you guys would like to know that you can grow and produce pecans in some of the northern areas now. Try pricing pecans!
