15 Best Weed Killers for Lawns
Scotts Turf Builder Weed and Feed
At an average price range of $20 to $50 for a large bag, Scotts Turf Builder Weed and Feed serves the dual purpose of nourishing your lawn while eliminating weeds. This product is granular, so you’ll need a broadcast spreader to apply it evenly across your yard. What makes it different is that it can both get rid of current weeds and stop new ones from growing, like a two-in-one solution for a weed-free lawn.
When applied in early spring or late fall, it effectively eradicates dandelions, clover, and other common lawn weeds while providing essential nutrients for robust grass growth. However, following the package instructions carefully ensures you’re not overdosing on your lawn, as excessive use can harm the grass and soil. In summary, Scotts Turf Builder Weed and Feed is an excellent commercial-grade option for weed control and lawn fertilization in one step.
Roundup Weed & Grass Killer Concentrate Plus
One of the most potent commercial concentrates on the market is Roundup Weed & Grass Killer Concentrate Plus, generally priced between $20 and $40 for a 32-ounce bottle. This weed killer is known for its fast-acting formula, often showing results within 12 hours of application. It targets the roots of the weeds, ensuring they don’t grow back.
The concentrate must be diluted before use, making it an ideal option for covering large areas. This formula is non-selective, meaning it will kill most plants it comes into contact with, so be cautious when applying it. Direct the spray or application solely on the weeds you wish to eliminate. Roundup Weed & Grass Killer Concentrate Plus works well, but be cautious to protect nearby plants.
Ortho Weed B Gon Weed Killer for Lawns
Another great choice is Ortho Weed B Gon Weed Killer for Lawns. It costs between $10 and $25 for a 32-ounce spray bottle. This weed killer works on more than 250 types of weeds and won’t harm your lawn if used correctly. It’s available as a ready-to-use spray, but you can also buy concentrate to mix your own solution.
Unlike the previous option, this weed killer is selective, targeting only the weeds, not the surrounding grass. Many users see results within hours, though the weeds could take up to 24 hours to fully wither away. This product is ideal for those with various weeds to tackle but want to keep their lawns lush and green.
Preen Garden Weed Preventer
Lastly, Preen Garden Weed Preventer is a pre-emergent solution that prevents weeds before they become a problem. The price range for this product is around $15 to $35 for a 5.6-pound bottle. This granular product can be applied directly to the soil in flower beds, vegetable gardens, and lawns to create a barrier that stops weed seeds from germinating.
Unlike other options, this is not meant for dealing with existing weeds. It offers a season-long protection, requiring reapplication every 9 to 12 weeks. For best results, it’s advisable to apply this weed preventer in early spring before the growing season starts. While it doesn’t offer a solution for existing weed problems, it is highly effective in preventing new weeds from sprouting, making it a perfect long-term weed management solution.
Southern Ag 2, 4-D Amine Weed Killer
