What is a tree spade?

A tree spade is a piece of heavy equipment designed to dig up and move large trees.

Small trees can be dug up and moved by hand, but what is a property owner to do when a mature tree is growing into power lines, standing in the way of a construction project, or casting shade on an area the property owner would prefer to be sunny? Many would respond by pruning the tree, or by destroying it entirely. Often, a better solution is to move it.

Tree spades were invented in the 1800s, and early versions could move trees more than 30 feet tall. Modern-day tree spade operators say they have moved trees well over 100 feet tall, as well as trees with trunks more than 5 feet across.

Tree spade operators don’t really recommend moving trees that large, though, since survival of the transplanted tree depends on whether enough of its root system can be picked up and moved with it. A tree’s root system can be larger than the aboveground part of the tree, but even the biggest tree spades can only dig up a chunk of soil about 7 feet across and 4 feet deep.

Medium-sized trees, though, can be successfully moved, and it is not even very expensive to do so – especially when compared against the cost of destroying the tree, including the loss of the services that a relocated tree could have gone on providing for many years.

By creatively rearranging our yards, we can have room for everything we want, while respecting the needs of many species.
