Question
I live in Western Michigan and I have three pine trees about 4-6 ft high that I want to move.  Can I move them in the fall or is it best in the summer?  How big of a root ball should I dig to move this big of a tree?  Thank you.

Answer
Trees  may be planted either in the spring or the fall. Deciduous plants may be moved in the spring as soon as the frost is out of the ground, up until the time when new foliage is partly unfurled. In the fall, they may be planted once the leaves start to turn colour up until the ground freezes.

Evergreens should be moved earlier in the fall than deciduous plants so they have time to form new roots. They need at least 6 weeks before the ground freezes. In the spring, Evergreens can be planted up to 4 weeks after deciduous trees have opened their leaves, providing that the newly planted trees receive adequate water.

When you want to dig up a tree or shrub for transplanting, retain as much of the root system as possible

All ages of evergreens, can be successfully moved only if a ball of soil is left around the roots. The exposed roots should be protected with moist burlap or newspaper or with polyethylene sheeting. Every effort should be made to reduce root exposure to wind and sun, keeping the ball as moist as possible. It's best to prepare the hole before digging up the tree you wish to move.

Size of the root ball and size of the hole:

For deciduous trees and shrubs the soil ball should be:

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.


Dig the new hole twice the size of the rootball and as deep and fill with top soil and mulch around the tree with not more than 3 inches deep of organic mulch not piled up on the trunk.
