Re: Ponds-Elimiating Bullrushs
Jim Lemke wants to kill all the bullrush in his pond and is having
difficulty finding a way. I have not had this specific problem but have
dealt with other invasive, impossible to kill plants - wisteria (the
terrestrial kind!) and kudzu. In the southeast U.S., kudzu is considered a
pest plant which was imported from Japan. Wisteria is an ornamental vine
that will break almost any trellis due to stem expansion. If wisteria is
cut back, it only sprouts again from any piece of root left in the ground.
Kudzu is the same situation.
I assume you've tried digging the bullrush roots but they keep coming back.
The only effective chemical eradicant for wisteria and kudzu is Roundup, a
tradename plant killer. If memory serves, it can not be used directly in
the water, but perhaps the kill method for kudzu and wisteria will work.
Mix up the roundup per instructions and leave in a large bucket. Place
the vine growth (in your case bend the bullrush new growth) into the bucket
and weight it down with a large rock. Make sure not to spill any roundup
on the ground. The above ground growth will absorb the chemical and
transport it to the roots (which is what you want to kill). After a few
weeks, the plant will die and not come back.
This is a radical method and you'll have to be very careful using it near
water. Good luck
