I agree with you!

In fact, two years ago, I cleared an acre of the Scotch Broom
and Spanish Broom with a chain saw (the Spanish Broom was up
to 6 inches thick or so and 15 feet tall or so).

The Spanish Broom came back with a vengeance, especially as
it sprouted around the cut stumps.

Then I learned you must paint with glyphosate (e.g., Roundup)
within five minutes of cutting.

That stopped the recidivists.

Then I learned that the seeds can remain viable for 100 years!

Wow. No wonder the invasive broom species took over the land!

I'd like to strangle the guy who brought them into this country!

Many years ago ODOT, Oregon Dept of Transportation planted Scotch broom
in newly constructed highway embankments to control soil erosion. Years
later, when they became aware of allergies and how invasive they are,
they tried to eradicate the Scotch Broom. Of course that never worked.

Crown Vetch is used in the East, with a similar outcome. I don't
think it's quite as bad, allergenically as you say, though.

Now they deny any responsibility! I recall driving by a planting of
Spanish Broom and being unable to breathe for almost a minute. Then I
learned to hold my breath when I passed the spot.

When was the last time you saw a politician (or regulator) accept
responsibility for *anything*. Remember, it's GWB's fault.
