Question
Hi, thank you for your answer on the Bradford pear. What if I want to transplant a White pine in the place of the other Bradford pear that was cut down. How would I go about that and what do I need to do to the ground and root system of the Bradford pear that was cut down. will the white pine have a better chance of living thought transplanting than the Bradford pear we talked about before thank you again

Answer
First I want to make sure we have our terminology the same--transplanting means to dig a established tree up and plant it in a new spot--planting a new tree is just that buying a tree and planting it.
Transplanting large trees whether they are hardwoods or conifers is not an easy job since the root ball needs to be large. And the chances of survival go down as the size goes up whether it is a Bradford or a pine. Planting a tree is the same location as another tree will depend on the root system and stump size of the old tree. If the stump was say 6 inches in diameter than the root system of large roots and the stump will take up about a 2-3 foot circle area. So planting right in that area will be difficult due to the woody material. You can move to the side and will have little trouble planting a new tree. The hole for the new tree should be twice the size of the root ball and as deep. Fill the hole with good top soil and mulch around the tree with not more than 3 inches deep of mulch, water once a day for the first couple of weeks.   

The root system of the Bradford that was cut down will over time decompose and may leave a sunken place that can be filled with top soil or sand. Nothing really needs to be done with this root system. Sometimes hardwood may sprout from the old  system if this happens you can spray the new growth with a herbicide called Roundup==make sure the Roundup does not get on any green plant not wanting to be killed.
