I have large banana trees that are taking over a section of my yard. I tried spraying roundup and it didn't seem to affect them at all. I sliced off the tops and poured salt in the wound and it didn't affect them either. Has anyone tried slicing them and pouring roundup/Glyphosate 4 Plus Herbicide in the wound to kill them. Once I get rid of them, I plan to have some in pots only. Ben in Atlanta.

Bananas can be vigorous (as you have found out). They will continue to produce new shoots unless you dig out the whole clump.

You might try using Remedy instead of RoundUp, or cover the whole area with black plastic - or both...

Ben, you need to spray the Roundup on the leaves, not on the stumps. The plants absorb the stuff through the leaves.

Still with bananas, as Hetty said you need to dig the whole clump to really be rid of them for good. You can chip away at it, a hunk at a time but you're going to find there's a huge root mass under there, I fear.
