Killing an ornamental pomegranate
I've got an ornamental pomegranate I'm trying to kill off. Someone planted it in an area that is completely surrounded by other trees, so the pomegranate itself isn't happy, and it's got a LOT of runner shoots all over the place, where it trying to find sunlight.
There're a few other complications with the location, too. It's right in the middle of a row of plants:
These plants are all spaced about 1 foot apart (!!), and I'm trying to save the citrus trees, so I'm nervous about trying to kill anything with salt and vinegar or borax, not knowing what that will do to the trees.
Does anyone have any advice for clearing out the pomegranate? And if it kills off the roses, too, even better...
