Spruce trees are one of the easiest tree species to replant. The most important consideration when transplanting a spruce tree is moisture. Once you remove it from its former location or bring it home from the nursery, make sure that its roots are not allowed to dry out while it is out of the ground. Once planted, keep its planting area moist to the depth of the root ball and it will soon take root in its new home. Although spruce is easy to replant, keep in mind that the smaller the plant the better. Spruce trees under 6 feet tall are the easiest to replant.
Dig a hole that is roughly twice the diameter of your spruce tree's root ball or container and a few inches deeper.
Place half of the excavated soil into a wheelbarrow or bucket and mix it with an equal amount of commercial garden soil.
Add a commercial, granular balanced tree fertilizer (follow the manufacturer's directions for the correct amount for your tree's size) to the soil mixture and mix it in well.
Plant the tree in the hole, using the soil mixture, so that it sits at the same depth as it did in its previous container or location. Do not cover the top of the tree's roots with more than 1 inch of soil.
Water the planting area with a slow-running hose so that the soil is moist to the depth of the root ball (insert a wooden dowel into the soil to test the moisture depth). Check the soil regularly and water whenever the top few inches of the soil dry out so that the tree remains moist until it establishes itself and produces new growth.
