Eradicate Glechoma Hederacea

Asked September 22, 2013, 12:34 PM EDT

What is the best product or chemical for eradicating "Creeping Charlie"? This would be applied in a cemetery on burial lots...an area 12' x 20'. It's chocking out the turf grasses.

Delaware County Pennsylvania

The above link is to the University of Minnesota and how they have researched eradicating creeping Charlie with Borax. The research has found it most effective if done it the spring and summer -- warm weather plays a big part. Also, if your site is shady, it is recommended that you consider what will be replacing the creeping Charlie as a ground cover. If nothing will be replacing it, the weed will come back. Please keep in mind that the active ingredient in Borax, boron, will accumulate in the soil causing yellowing and dead patches, if used too much. It is recommended that this Borax solution be used only once a year.
If the creeping Charlie is in a garden bed, it is suggested not to use the Borax - the toxicity of the boron to other plants. If it is in lawn, you will see some yellowing of the lawn, but it should return to green.
The mix is 10 oz Borax dissolved in 4oz (1/2Cup) of warm water, then dilute with 2 1/2 gallons of water. This will cover 1000 square feet.
