Last season we added this Prairie Fire crabapple tree. When it was delivered it had a rootball full of carpenter ants and a lot of damage to a 6 inch band of bark around the soil line. The nursery said it might be due to grafting, but it looked pretty severe. The tree has seemed to thrive despite the damage. It just started blooming two days ago. The color is breath-taking, and it is blooming profusely. I can see this one getting more and more spectacular every year.
