This can also work. Glyphosate is not as effective as triclopyr. As such, repeated applications are more likely to be needed.

Dead trees can remain standing for a long time - depending on the species and the climate. However, we do not recommend creating dead trees that are near something of value (a house, garage, pool, etc.) In that case, it would be best to hire a professional arborist to cut it down.

This will depend on what chemical you plan on using. You should always follow the instructions on the label of the specific chemical you are using.

I'm sorry for the delay in reply. Hack n Squirt can be effective with triclopyr amine (Garlon 3A is one of many of the brand names). Glyphosate (aka roundup) is also able to be applied by this method but should be done late summer or early fall for best efficacy.

thanks adam! what level of concentration for the late summer early fall of glyphosate?

Striping the bark alone, will not kill the tree's root system. Appropriate herbicides are needed to kill the root system to prevent resprouting.

your the best adam! thank you for following up years later!

Good question and an interesting one to debate. Most of these are relative new comers to North America. And as for me, I will do what I can to give native plants a better chance by discouraging non-native invasive plants.

Doesn't really matter. If they were here before humans, they'd probably be considered native (indigenous) --- because who'd know if they weren't, (they'd probably be troublesome if they didn't actually evolve here though). However, if the plants don't cause problems people generally don't worry much about them. If they are problematic, then eliminate them. Those troublesome species can be non native or native. My biggest problem is hickory.
