mollis Bear's breeches
How can we get rid of Acanthus mollis (Bear's breeches)?
We have dug, dug and sprayed with several weedkillers, but still
it comes up where we don't want it!
Breeches are great for dramatic foliage in a large garden, but they
can become a nuisance. They are very hard to kill off and continuous
spraying is required. You may find that you have to cut all the
foliage off and then spray the new tender growth that appears.
You could try Yates Amitrole
or Woody Weedkiller. Add these to Yates Sprayfix to help the chemicals
adhere to the leaves. If you are able to, try cutting the base of
the plant and pour Amitrole down the cuts into the base or roots
of the plant. Be very careful if you try this, as you don't want
any chemicals to get in to the soil water table. The chemical stays
in the soil for up to four weeks and you must be careful that other
desirable plants aren't affected. This may take you a couple of
seasons to get rid of, but I am sure that you will succeed.
