re: Best spray to kill elephant ear and banana plants

I had both on my current property when I bought it in 92. I got rid of them simply by cutting them to the ground and every time they started to show any signs of sprouting, I'd take a shovel and cut it back down to the ground.

If photosynthesis can't take place, the roots eventually die. This didn't happen overnight, but just keep removing any growth whenever it shows and they will eventually die.

I've been here since 92 and after that first year or so, no banana or elephant ears have grown in my yard.
