Looks like last week the emerald ash borer was discovered in St. Paul. I guess we all knew it would be here eventually but I figured it would have been a few more years. I personally have 2 green ash in my yard that will eventually be replaced. I plan on planting two smaller trees near the ash, so that when the time comes they will (hopefully) be established. I just can't justify the expense and risk it would take in treating them. Any other thoughts.
