Re: Discussion: killing creeping charlie

I believe Paul is correct.  I live in apple growing country and apples need
slightly more boron than other plants.  The apple growers are very careful
to test the soils before application because too much boron can end up in
fruit and cause human toxicity.

Folks,

I posted a response concerning how to kill creeping Charlie that I received
from a local nursery owner (also an international speaker) who has a great
memory and knowledge of plants. Before you jump out there with your
20-Mule-Team Borax, read this whole note, which starts with my original and
then includes a strong statement against this idea plus a warning:

>From my expert:

Creeping Charlie...or Glechoma...the variegated one is great in
containers but I wouldn't let it out.  To kill the plain green one in a lawn
or flowers use Borax mixed with water and spray on the lawn.  About 1/4-1/2
cup per gallon of warm water.  Repeat weekly until it dies.  It works by
raising the boron level in the soil which is harmless to other plants but
will kill the creeping Charlie.

Contrary opinion:

Hate to be a party pooper- but boron is a very toxic poison to almost all
plants.  the Creeping Charlie is very sensitive and reacts sooner than other
plants.  The repeated use of it in the same soils or mixing more than what
is recommended will result in death of most plants for a few years in the
treated location.

I've sent Paul's response to my expert, and will post his reply.
