Recently relocated to the Dallas area from Seattle. Needless to say, the growing is a little different. I have purchased (3) 15' pines for my backyard for some screening and will be planted on Wednesday. Now, I have another so called expert telling me the trees are junk. The tree farm said they have been grown here and as I say, they are 15 feet tall now. He called them an Afghan Pine, or Eldirica or Mondale Pine and says they will do great in my sandy soil. Can anyone with experience in Texas growing confirm or deny? Thanks
