20 Best Lawn Weed Killer Granules (2023 Updated)

Lawn weed killers come in many different formulations, but most contain some form of herbicide. The active ingredient in herbicides kills weeds by disrupting their growth cycle. Lawn weed killers are available in both granular and liquid form.

Granular weed killers are easier to apply and tend to be more effective at killing weeds.
