If my Mom looks at them they are going to die. snort Plastic plants turn
black when she gets her hands on them. It's really embarrassing. I always
think "poor plants" when ever she heads to the garden center.

What would work? No water, no nutrients. Black thick plastic weighted down
by bricks. Leave through the summer over the area that you want decimated.

You'll have an empty place to 'start over' on. Till in good compost,
aerate, plant it.
