2 years ago I bought 3 white pines (about 4 feet tall) One died same
year. After digging it out I noticed that when balled, the grower
severly cut the center root. I believe this caused the tree failure.
The remaining 2 trees have not grown an inch. I believe their center
roots have been cut too. Is there anything that I can do to turn this
trees around? I treated both with liquid root stimulator last spring,
but no growth.
