How to get rid of:
Mulching, depending on the size and depth of the mulch, can prevent seedling establishment. Before seeds germinate, a 4-inch thick organic mulch (e.g., compost, wood chips, etc.) can prevent establishment. Organic mulch can also be applied after the seedlings have germinated but must be applied in a thicker layer (4 to 6 inches) and must cover the plants completely to block out all light.
The most common products for this application contain Glyphosate
or Glufosinate as active ingredients listed on the label. These herbicides work by translocating the
product through the leaves to the roots where they interfere with the growth process. The best
control is accomplished when applied to young plants. Both these products are non-selective,
meaning they will kill any growing vegetation, both grass and broadleaf plants.
