Question
I just moved 12 medium size furs on oct 18 should I be concerned?

Answer
No they should be fine. Evergreens are best moved earlier in the Fal than hardwoods and before the hardwoods drop their leaves and before the ground freezes. This extra time gives the roots more time to grow for the next summers heat. IF you have not done so I would mulch around the trees with not more than 3 inches of organic mulch not piled up on the trunk. This will help hold moisture and also help keep the roots from freezing during cold weather.
