My backyard is surrounded in chain-link fence. Beyond my back yard is a small wooded area with tons of Mulberry trees. So, when birds eat the Mulberries and sit om my chain-link fence, I get trees which have grown to swallow my fence (and along my house).
I can't get to them with a saw to chop them down first due to all of the metal so I needed a good way to remove them without risk to the fence, saw, or anything else. This method does exactly that.

Step 1: Fill Your Floral Tubes
This is a pretty basic step.
One trick that I used was to poke two small holes (1/4") on opposite sides of the foil lid sort of like how you would do for a can of pineapple juice. This allows you to control the opening that the fluid is pouring out of and vents the bottle so that you don't pour it all over yourself.
Note: wear gloves just in case.
Step 2: Cut a Branch, Install Your Tube
Again, it's pretty simple.
Cut a branch that is about 1/4" in diameter and doesn't have a leaf or branch fork any more than an inch away from the cut. Gently install the tube. If you press too hard, the branch will jam up into the tube and force most of the brush killer out.
It's advisable to get as close to the main trunk/stump as possible. If you are too far away, it will only kill that branch and the ones near it. If you can't get close to the trunk, get as close as you can and just use two or three tubes.
Step 3: Two and Three Weeks Later:
Within a couple of days you will start to see results. These photos are taken two and three weeks after one tube was put on the tree (there is a second tree in the middle of it that I didn't notice because I wasn't looking). Some of the leaves are already dried up and have fallen and the rest of the tree is clearly sick.
I have used this technique to take down trees up to five inches in diameter by using multiple tubes. Once they are dead, you can either trim them so that they are less unsightly or leave them.
