If you wonder what I mean when I say “we put a survival ring around a tree,” this might help explain the process.
First you need a tree with ivy on it. And here it is!
Before we pull the ivy off the tree, we build a platform to dry out the ivy and let it rot in place. In a few years, it becomes humus.
First we put down a layer of burlap, to prevent shoots reaching up into the platform. Then long, thick logs (in this case, more than six feet long, and a couple inches in diameter) to form a square. More thick logs are laid out between the square, then a grid is formed by placing thinner logs across the bottom layer. The more separation between ground and platform the better. Then you can put the ivy on the platform.
The ivy is cut at shoulder height. The ivy above the cut is left in place to die, and the ivy below the cut is pulled away from the tree. This sometimes takes a great deal of effort. Ivy roots can reach several inches in diameter, and roots growing close together will fuse into a solid mat. A crowbar is one of the most useful tools for this kind of work.
It was taken from pretty much the same position as the “before” picture. The ivy above the cut will die, but it might take awhile. Even so, it will stop growing up the tree.
This tree was more than 35″ in diameter, and was about 100′ tall. The complete circumference was covered by ivy to about 70′.
