It really took off these past couple of years and is thriving nicely. Unfortunately the ash tree that was planted at the same time is not doing well at all. The city planted those two trees on the boulevard shortly after I moved into my house.

Hey Ed,
I think Minnesota has more ash trees than any other state and unfortunately the little bastards are headed your way. I know there is a lot of work being done on biological defense, a certain type of wasp and a fungus, but it will likely be too little too late. Apparently it all originated from overseas shipping containers shipped to an automotive plant (Yazaki) in Canton Michigan in 2002.
I think important trees can be saved, but they need to be vaccinated before infestation and then annually on a permanent basis. I got started too late on mine to save it.
