thuja green giant

I planted 4 green giants this spring (about 3 ft. tall). I would like to transplant them in my backyard. Would this fall be the best time to do this? I live in Maryland outside of DC. Thanks.

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. 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 as deep as the root ball and twice the width. Fill with good top soil and mulch with not more than 3 inches of good mulch and water.
