Q: Drought was stated as what caused the trees' death, only dying pine trees were pictured. No mention of the boring insects that kill pine trees, was that omission intentional? No pictures of dying deciduous trees either. I have seen dead pine trees in peoples' yards where their lawn is nice and green - they water the lawn and trees - yet the tree is dead. Is drought or boring insects the reason for so many dead pine trees in Lane County?
Plant hormones and growth regulators are chemicals that affect flowering, aging, root growth, distortion and killing of organs, prevention or promotion of stem elongation, color enhancement of fruit, prevention of leafing and/or leaf fall, and many other conditions.
