re: Best spray to kill elephant ear and banana plants

This is what worked for me when trying to get rid of both bananas and cannas after cutting them. When resprouting make a horizontal cut on the re-sprouts at near ground level and immediately “paint” the fresh cut with trichlopyr herbicide (8.8%). You can purchase that as “stump and vine killer”.

May have to repeat the process the rest of the summer to get them all, but I was really surprised at how well this worked.

I did dig out some of the bananas roots first but as you know you can’t get rid of them all. If you have a big area, might need to turn on the music and drink some cold ones while cutting and “painting” b/c it is a pain in the azz.

If you do have a bigger area and mega stumps to deal with you could try the more concentrated form of trichlopyr (61.6%) and spray it on freshly cut stumps and emerging leaves.
