Tip

Content: This is especially helpful when treating large stands of yucca so you know which plants have already been sprayed. Alternatively, you can keep a bright-colored spray paint on hand and spray the leaves of each plant after applying the herbicide. Apply the Herbicide
Hold the spray nozzle over the center of each yucca whorl – the round cluster of yucca leaves – and spray for about two seconds. Repeat with each whorl within a yucca cluster. A yucca plant might only have one whorl of leaves, but can have several separate whorls. If the yucca plant has a fleshy trunk, spray the trunk with the solution as well, in a process known as basal bark application. Recheck the Plant After a Week Has Passed
Allow about one week for the herbicide to take effect; the leaves will slowly turn brown to indicate the plant is dead. Treat the yucca a second time if no change is noticed after seven to 10 days. Remove the Yucca Root
Dig up the yucca root to ensure that the plant cannot grow back.
