Content: 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. Dig a wide circle around the plant to ensure you pull up all of the root. Sort through the soil after removing the largest part of the root so you can remove any smaller, broken pieces of the rhizome. Once you've finished, Ohio State University recommends spraying the area with a weed killer to prevent any remaining root segments from sprouting. Use this as a last resort if you have previously tried to eradicate the yucca with herbicide and it grew back in the next year. Things You Will Need
Garden sprayer
Glyphosate or triclopyr herbicide
Diesel fuel or vegetable oil
Blue spray-marking dye (optional)
Shovel
Tip
A 1-gallon sprayer is not necessary if you only have a single, small yucca to kill.
