How do I kill Knotgrass (Paspalum distichum)?
How do I eradicate this horrible weed, firstly in amongst plants in garden beds and then thoughout the lawn, to stop it coming back. Lucy.
A selective herbicide is needed to kill a grass weed within a grass lawn. Although we are unable to help you with this type of herbicide you may be able to locate a commercial product through a rural supplier.
