Lenny Wells of the University of Georgia posted an interesting story in his Pecan Blog a couple of weeks ago on the impacts of heat on pecan trees when temperatures were so warm. It turns out that pecans can do well in very high temperatures as long as they have the right amount of water. Research has shown that photosynthesis in pecan can continue with no ill effects at leaf temperatures as high as 106 degrees as long as soil moisture is adequate, according to his post.
