Types of Weed & Grass Killers at Do it Best
Weed and grass killers are designed to eliminate unwanted plants down to the root, making them great for use on driveways, sidewalks, patios, gravel areas, landscape borders, and other spaces where complete growth control is the goal. Choosing the right weed and grass killer requires an understanding how quickly you need results and whether you want to replant grass seed afterward.
Do it Best offers the following types of weed and grass killers:
Control Type | Best For | Typical Results |

Areas where future weed and grass growth is unwanted | Kills existing weeds and prevents new growth for months |
Consider Whether You Plan to Reseed or Plant
Not every weed and grass killer works the same when it comes to future seeding. Some products allow planting flowers, shrubs, trees, or grass seed within days after treatment. These formulas are best for preparing garden beds, renovating lawns, or clearing planting areas before new landscaping.
Other products include long-term preventers that create a barrier in the soil. While they’re excellent for preventing future weed growth, these products won’t allow for reseeding or planting because they continue affecting the soil for months after application. If you’re planning on reseeding or planting in the area, make sure you choose a grass and weed killer product that isn’t mixed with a preventer.
Selecting the Right Grass & Weed Killer for Your Application
Before choosing a grass and weed killer, you’ll want to think about where you’re applying it and what your future goals are for the space. Consider the following before making your decision:
- Concrete & Gravel: Driveways, sidewalks, pavers, and gravel surfaces typically benefit from products that include extended prevention. Since vegetation is generally unwanted in these locations, longer-lasting control reduces maintenance throughout the season. If one of these areas is what you’re treating, look for a weed and grass killer mixed with a preventer.
- Landscaping & Flower Beds: Landscape areas and flower beds require products that kill existing weeds but allow future planting. Several weed and grass killing products are designed to work around trees, shrubs, and flower beds when applied carefully according to label directions
- Large Properties: Large property maintenance projects often need concentrated formulas capable of controlling brush, vines, perennial weeds, and other difficult weeds. These products provide broader coverage and have better value for larger properties.
Getting the Best Results from Weed & Grass Killers
Consider the following before applying weed and grass killers:
- Apply products when weeds are actively growing and have enough foliage to absorb the treatment. Warm temperatures and dry weather generally improve effectiveness for many products
- Avoid mowing immediately before treatment, as more leaf surface allows better absorption.
- For products with rainfast guarantees, follow the label recommendations regarding rainfall and watering after application. Many formulas become rainproof within 10 to 30 minutes, but others may require longer drying periods.
- Always avoid contact with plants, lawn grasses, shrubs, and trees that you want to keep unless the product is specifically labeled for those uses.

Weed & Grass Killer FAQs
Grass and weed killers are not intended for use on lawns because they kill grass along with weeds. They are best used in areas where full growth control is wanted.
Many products show visible results within hours, but some options, like complete root kill, may take several days or weeks depending on the weed species and product used. Read the product label before purchasing to find specifics based on product.
It depends on the product. Some allow planting within days, but some include long-term preventers that require you to wait months before reseeding or replanting. If you plan on reseeding, avoid a product with a preventer, and always follow the label directions.
These products are commonly used on driveways, sidewalks, gravel areas, fence lines, patios, landscape borders, brushy areas, and sites being prepared for renovation or replanting. They’re rarely used directly on lawns because they kill grass and weeds at the same time.
