摘要

Not all pecan trees are healthy. Many pecan orchards have trees experiencing stress symptoms and some have hidden or non-visible hunger signs. January and February are good times to evaluate tree health as one can observe dormant shoots throughout thetree.The best way is to look at shoot length in the top of the tree. Trees with short, dead or rosette growth are not in good health. On the other hand, if shoots are 6 to 18 inches long, the tree is in good shape. Shoots 24 to 48 inches in length are too vigorous which could reduce flowering and production. The late Hugo Pape would say, it is not just shoot length, it is also shoot diameter. One can have short fat shoots, which is also a sign of good health. We need to appreciate the importance of good treehealth and make a serious effort to observe and study shoot length and quality.
