The Q&A Archives: Eliminate wild garlic from yard

Question: What are methods of eliminating wild garlic from yards?

Answer: Killing wild garlic isn't easy, but if you are persistent, you'll eventually rid your landscape of this weed. It is a year long process. Kill wild garlic plants throughout fall, winter and early spring before plants can generate the next generation of bulbs (in March). Pull or cut down any that emerge in the summer.

Hoeing throughout winter or early spring will prevent development of new underground bulbs. If hoeing is not an option, 2,4-D applied before plants are 8 inches tall also provides effective control. Use caution when applying 2,4-D; it is a broadleaf weed killer which can also kill ornamental plants. Make sure all herbicides are labeled for the site at which they are being applied.

Wild garlic bulbs can persist dormant in soil for 6 years. Nothing sprayed above ground can kill dormant bulbs beneath the soil surface. Complete control of wild garlic cannot occur in a single year. Persistent management for at least 3 or 4 years is necessary to obtain complete control.

Good luck with your project!
