This method works great for trees that a vehicle can't get to.
When there's vehicle access the A-Frame method of tree moving works great . Manual methods work okay for small trees. But I have ten biggish fruit trees to move with no vehicle access. New methods are needed.
This is big heavy stuff. It can fall and crush heads and bodies.
Ropes under tension can snap and fly a long way.
I've seen it happen. It can cause great damage to people and property.
I saw a broken rope fly through a car breaking back window and windshield. It sounded like a gun.
Don't hurt your back. Trees grow much faster than a back can heal.
Step 1: Or rather, Ancient ones...
This image is supposed to be from Samuel Hayes c.1794 but I can't find it in the book.
Exposing the roots and taking as many as you can with you can be a good thing, but don't let them dry out for very long.
Step 2: Get Welding
It's much better to move them when they're asleep. Like vampires.
The rainy season is coming to an end. We've had our two feet of rain for the year. It might not rain for another six months. When the East Bay flats dry out, that rich black clay soil turns to hard adobe. That makes the digging very difficult.
There's not much time left, and I've got ten trees to move. Pressure.
Pressure underground makes coal into diamonds.
Pressure in the human bloodstream makes caffeine into a shamanic drug. It allows the artist to unhinge the lower jaw of the imagination and swallow a design problem.
I listened to lectures from the London School of Economics on Jackhammer Headphones to distract my conscious mind. The hands and subconscious mind are much better designers.
I walked around the lot and grabbed what I needed. A couple of wheelbarrow wheels and a lot of scrap square tubing. I did most of the welding with my spoolgun welder powered by the solar golfcart. When it got too windy I moved indoors and finished with commercial MIG gear. Soon I had the frame in this photo. The headphone lecture made me well acquainted with "Agency Cost Control" as a guiding principle of corporate law ( Oversee and limit the power of managers. They inevitably have a conflict of interest.).
Unfortunately designing with the hands and subconscious does not result in good photography.
Step 3: The Finished Tree Dolly
The mast is douglas fir. 9cm square, 3.5 meters long.
It slides into rectangular brackets and is retained by a 15mm steel pin through the bottom bracket.
The shopping cart next to it contains some giant steel hooks I made to lift the tree's root ball.
Step 4: First Use!
Just as seen in that old engraving. But I carved a root ball instead of trying to do a bare root transplant.
Roll your mouse over the yellow rectangles in the photo to read about what's going on here.
Step 5: Tipped for Transport
It's amazing how little force it takes on the mast-head rope to lift and tip the tree.
Don't let the dolly fall and clobber anyone on the head.
More innertubes secure the rootball to the dolly.
Step 6: Anchor and Guy, Ready for Planting
I pounded the hook into the ground with a sledge hammer and some wiggling.
I tied the guy line to the hook. The curved hook is a lot easier to get out than a straight stake. Wiggling it enlarges the whole hole so it pulls right out.
When we untied the tree it swung to the right and the dolly started to tip. So we blocked up one end of the 2x4 under the dolly frame.
Step 7: Planting
We leaned the dolly over the hole so we could spin the tree as it hung suspended. That made it easy to get rotated just right.
The 2x4 under the frame keeps the dolly from falling into the hole. Also makes it easier to keep it from tipping over sideways on the irregular ground.
Dig a bigger hole than you need.
Spade and fork up the dirt in the hole so it's loose. If the destination dirt isn't the same as the root ball dirt, mix the two types so there's no abrupt change between the two. After the tree is in the hole and is standing upright, I remove the innertubes and carpet scraps around the root ball.
Plant the tree no deeper than the bulge at the bottom of the trunk.
Mulch all over the top of the roots, but not quite up the trunk.
Then water the tree thoroughly and regularly.
If high winds or college students are in the area, tie stakes and guy ropes to the trunk so it doesn't get knocked over.
Step 8: Next Tree
The soil is too dense for me to undercut the whole ball with my long sharp shovel. So first I trench around the tree.
I tried to move the biggest root ball I could manage with this tree. That meant a lot of extra digging as I figured out how big I could make it without it breaking apart.
There's a plastic water pipe there, but it ends right at the root ball.
Step 9: Rigged, Wrapped, Undercut, Lifted, and Tipped.
Volume and mass of a solid grows with the cube of linear dimension.
That is (length X width X height) = volume. Volume X Density = Mass.
In other words, it gets a whole lot heavier from small increases in size.
When you scale it up linearly, the mass grows exponentially.
