Up until recently, moving large trees always required the severing of parts of the root system. A new technique for moving ...
trees, called the bare root tree planting method, makes it possible to move trees without damaging their roots. Dave talked to some experts about this new technique for moving trees at the 2010 New England Grows trade show; take a look.

Dave Epstein: Hi I'm Dave Epstein here at New England grows and I've got an air spade in my hand. And you know people come here, the horticultural professionally come here to learn about the latest techniques going on in the industry. One of them is moving large trees.
So you at home you might have a big tree that you want to move and you think we can’t move that with an air spade they actually blow the dirt from around the tree, it exposes the bare roots and they are able to move trees that are really big 20, 30, 40 feet high in the middle of summer fully leaved out.
We’ve never really seen that in the industry before. This is the way to move those large trees without having any of the problems that we have if we slice the roots. Let’s go take a look at somewhere else in the tradeshow floor to see what one of those trees looks like.
So here we are 30-foot Zelkova, the air spades has been used and blown all the dirt the away and look at the roots they’re bare. They're keeping this a little moist so that the tree doesn’t die, this will be put back in the ground no problem at all. All of the roots are saved. And when you move the trees, you don’t have the same problems with wilting or tree die-back or any of those other issues.
So I run in to Mike Santoro, he actually works on this air spade technique. So Mike, tell me why this is so much better than sort of traditional big tree moving.
Mike Santoro: Well traditional big tree moving utilizes a tree spade which cuts the roots. I can explore the root system then preserve almost 100% of the root system. Most of the nutrient absorbing roots are at the end of the root system and when you use a tree spade they’re cutting off those fine roots that absorb most of the nutrients. In that sense you are limiting the amount of nutrients that the tree can take up.
And when I excavate the soil around the root flare I can discover any problems I might have with girdling roots and any root malformations that have formed and take those away from the roots. It also decompacts the soil around that root system.
Dave Epstein: What do you find is the result later on after the tree has been planted, what’s the health, how does that change?
Mike Santoro: Typically when you transfer that tree the next year’s growth is stunted a little bit, we’re not having that when we have transplanted bare root. It continued its normal functions as if it was in its natural environment.
Dave Epstein: So if you're going to move a tree, talk to your certified arborist and ask them, are they using air spades. It’s a fairly new technique, not all arborist are going to use it but you definitely want to find someone that is because that means they're on the cutting edge.
