I planted a red Dogwood in my yard about 4 or 5 years ago. Unfortunately, through my neglect and inattention, it all but died. But...it wants to live! It is struggling and keeps leafing out each spring. I am fertilizing and watering it this year like never before. But every time there is new growth some insect decides that it is dinner time! I've given it systemic insecticide as well as spraying it. I don't have the heart to take it out because it is trying so hard to survive! Will see what my TLC this year will do for it next year.
The leader was chewed off a couple of years ago and then the tree started dying back, but always seemed to have one branch that would keep growing. If you look at the base of the tree there is a new branch trying to grow from there which might actually produce another trunk. But only if the bugs will stop chewing the leader.
