Question -
i live in erie pa, and there is to be some new construction, and there is a ---100 ft pine tree, christmas tipe, that probably is 50 years old.

1. can this tree be transplanted
2.are the roots  deep enought to transplant?
every time i see a pine tree up rooted the roots are shalow and spread out.
3. is this tree to old to transplant with a tree service, crain truck? to a arboretum

Answer -
The easy answer is No it can not be transplanted.
The problem is the size. To properly transplant a tree you need to dig a root ball. The width and depth should be as follows:

Width = 9-12 in. in diameter/every 1 in. of tree diameter
Depth = 6 in./every 1 in. of tree diameter

For example: A tree trunk 2 inches wide would need a soil ball of 18-24 inches wide and 12 inches deep.
A 50 year old tree I would guess would have a diameter of at least 12 inches. That would make a rootball of 144 inches or 12 feet across and 6 feet deep.

To calculate the weight of the soil ball before you move it, use this formula:

Weight of soil ball = width of ball x depth of ball x .05 lbs.

For example: A tree trunk of 2 inches wide would have a soil ball that weighed:
(24" wide x 12" deep) x .05 lbs = 14.5 lbs.

A tree trunk of 4 inches wide would have a soil ball that weighed:
(48" wide x 24" deep) x .05 = 56 lbs.

a tree trunk of 12 inches diameter would have a root ball that weighed:
(144" wide X 72 " deep)X .05 = 518 lbs.

So it can be done BUT it will cost a lot of money to get someone to move this large a tree and Pines have a Medium to low chance of survial when transplanted when large.

Answer
Rooting of pines is not easy but can be done. I would recommend gathering cones and letting them dry and open and get the seeds out of the cone and plant the seeds. Much easier and more sucessful. Place the seed in the refrigerator until spring and remove and plant them in good potting soil just under the soil. When they get too large for the container transplant them into a large one and when the seedling get about 12 inches tall out plant. For your information here is a web site about rooting.
