Cypress trees are conifers, a type of evergreen, and may be transplanted at various stages in their growth. It’s easier to transplant a smaller cypress tree than it is a larger one, but either can be accomplished using the same method and proper attention. Take special care when transplanting cypresses to preserve their root ball. The best time to transplant cypress is in the fall.
Prune off any dead, old, or unwanted branches before transplanting, if desired. Lower branches that may get in the way of transplanting are good targets.
Dig a circle around the outer edge of the root ball with a sharp shovel. The diameter of the edge depends on the size of the tree, and should be about halfway between the trunk and where the outermost branch reaches. Cut down with the shovel evenly, facing the tree as you go.
Turn 90 degrees to the circle, facing sideways to the tree. Dig a trench outside the circle, making small shovelfuls to avoid breaking up the root ball. Face the shovel sideways to the circle to reduce root injury.
Deepen the trench. Dig it another 1 foot deep, now facing in toward the tree, and at an angle. When you've completed one circle, turn sideways to the trunk again.
Enlarge the trench, aiming to get under the root ball. With cypress, this usually will not be more than 1 or 2 feet down. Remove as much soil as you can while still leaving the main root ball in one piece. Stop when you can rock the root ball back and forth easily.
Slide a bunched-up tarp under one side of the root ball. Then lean the root ball toward the tarp and, with the help of another person, pull an edge of the tarp all the way under so that it holds the root ball. Unfold or pull the tarp so the root ball is centered on it. One or more people then can grab the tarp at its corners, evenly supporting the root ball for transportation.
Prepare a new planting hole for the cypress. Dig a hole twice the size of the root ball in width, but just as deep as the root ball’s height. It’s better to place it a few inches too shallow than too deep. Place the root ball in its new hole and re-cover it with the soil you removed.
Water thoroughly after transplanting to get rid of any air bubbles in the soil. Fertilize lightly with a conifer fertilizer, if desired.
