Specifically, we’ve successfully treated large areas of poison ivy, which, depending on the species, grows in both shrub and vine form. Tordon eliminated some poison ivy vines nearly 30 feet long with a base stump diameter of almost 2 inches. To date, every stump we’ve treated with Tordon has died and hasn’t sent up any additional shoots. There may be a tree or shrub out there that Tordon won’t kill, but we haven’t run across it yet.

Since the active ingredients in the liquid speed up the decay of the wood, it can work on different tree species and of all sizes. All you need to do is dig four holes in the stump, pour the granules into the holes then add water. It usually takes between 4 to 6 weeks for the stump to decompose. If you’re in a hurry, just pour gasoline over the granules and set the stump on fire. It will turn into ash within a few hours. There are times when cutting down a tree is the only option, whether we like it or not. This is especially the case if the tree is diseased or posing a safety risk.

The Tordon label warns against using the product on stumps in or near water because it will carry in waterways and may kill other vegetation—and perhaps even aquatic life.Another feature we liked was the no-freeze compound that is added to the liquid.

The anti-freeze quality means that liquid will stay usable and the stump will absorb it even in cold temperatures.
