Wild Garlic: A Common Winter Weed in Lawns | Winter Weed Control

If you’ve noticed thin, glossy green shoots popping up in your lawn during the colder months along with a strong onion-like smell when you mow, you’re likely dealing with wild garlic. This cool-season perennial weed is one of the most common winter invaders in Southern lawns and can be surprisingly stubborn if left untreated.

Wild garlic thrives in fall and winter when turfgrass is dormant or growing slowly. It spreads through underground bulbs, which makes it tougher than many annual weeds. Simply mowing or pulling the tops won’t solve the problem. The bulb remains underground and will send up new growth again and again.

Beyond being unsightly, wild garlic can crowd out desirable turf and leave bare or thin spots once it dies back in late spring. Those weakened areas are prime real estate for summer weeds to move in later.

The good news? Timing matters. Winter is actually one of the best times to control wild garlic. Targeted herbicide applications during active growth are far more effective than spring or summer treatments, when the plant is already winding down.

If wild garlic is showing up in your lawn now, it’s a sign that proactive winter weed control should be part of your turf care plan. Catching it early helps protect your lawn’s health and keeps those pungent surprises out of your next mow.
