The story... The Commander of my Base decided that he did not like grass between the Hangar and the main road on Base. So they decided to put in mulch beds with ground ivy. Well the ivy has not done what they thought which is cover the ground. So now they want me to kill them all. Well I have used roundup, hyvar and even some oust but it won't die. Doesn't seem like anything will cut through the waxy coating. Besides using diesel fuel what will work?
