Introduction to options: For St. Augustine and Bermuda lawns, select products that clearly state compatibility with warm-season grasses and provide either pre-emergent weed control, post-emergent control, or both, alongside a balanced feed. The five products below have demonstrated effectiveness across typical suburban landscapes and address common weeds such as dandelion, clover, dollarweed, crabgrass, and other broadleaf varieties.
Fertilome (13917) St. Augustine Weed & Feed 15-0-4
The Fertilome 13917 is a combined weed control and fertilizer product designed specifically for St. Augustine, Centipede, and Zoysia lawns. With a 15-0-4 formulation, it delivers nitrogen to support green up while addressing common weeds through pre- and post-emergent action. It should not be used on Bermuda or other Northern grasses. This product targets both existing weeds and future germination, offering a practical one-step solution for seasonal weed pressure and nutrient needs in warm-season lawns.
BioAdvanced 3-in-1 Weed and Feed for Southern Lawns (10 lb)
This BioAdvanced formulation is tailored for Southern lawns, including Bermudagrass and Floratam St. Augustine. It provides up to six months of weed prevention by combining weed control with lawn fertilizer. It targets broadleaf species such as dandelion and clover, as well as certain grassy weeds, helping to protect warm-season turf while delivering steady nourishment. The 10-pound bag is convenient for smaller to mid-size lawns or for spot treatment within a larger lawn program.
Spectracide Weed & Feed 20-0-0 (32 oz) Ready-to-Spray
Spectracide’s 20-0-0 Ready-to-Spray combines broadleaf weed control with lawn feeding in a convenient spray format. The dual-action formula both kills listed weeds, such as dandelion and clover, and nourishes the lawn with a nitrogen-rich feed. This option is particularly suitable for homeowners who want quick, spray-applied coverage and clear weed control results without requiring mixing or measuring. It is compatible with Bermuda and St. Augustine lawns when used as directed, but always consult product labels for specific regional guidance.
BioAdvanced 3-in-1 Weed and Feed for Southern Lawns (20 lb)
In the 20-pound granule format, this BioAdvanced option offers extended weed prevention for Southern lawns. With the same emphasis on Bermudagrass and St. Augustinegrass, it delivers a robust one-two punch: weed suppression and continuous feeding for up to half a year. The larger bag size suits bigger yards or those who prefer fewer restocks. Weed killers included target listed broadleaf and grassy species, while the fertilizer portion sustains lawn vigor and color. It is essential to follow application timing for best results and to avoid Bermuda during sensitive periods if labeling advises.
The Andersons Premium Weed and Feed 24-0-16
The Andersons Premium Weed and Feed uses a 24-0-16 formulation designed to promote rapid green up while delivering sustained nutrition through both quick- and slow-release nitrogen sources. It targets a broad spectrum of weeds with post-emergent action complemented by preventive weed control. The product supports larger lawn areas, providing robust coverage and a long-lasting feeding regimen that helps establish a resilient warm-season lawn. Its comprehensive approach makes it a solid option for homeowners seeking a dependable, all-purpose weed-and-feed solution.
Buying Guide
- Lawn type compatibility: Confirm the product is labeled for St. Augustine, Bermuda, or other warm-season grasses present in the yard. Some formulas explicitly exclude Bermuda or Northern grasses.
- Weed control vs. feeding emphasis: Decide whether you need pre-emergent weed prevention, post-emergent control, or a combo, and choose accordingly.
- Weed spectrum: Consider the common weeds in your area (dandelion, dollarweed, clover, crabgrass) and select a product proven to address those species.
- Application method: Granules vs. liquid spray influence ease of use, coverage, and timing. Ready-to-spray formats may be convenient for larger patches.
- Seasonal timing: Warm-season grasses have specific growth windows. Follow label directions for optimal results and to avoid stressing the lawn during peak heat or dormancy transitions.
- Bag size and coverage: For larger lawns, larger bags reduce the number of applications and may provide better value, but ensure you can apply evenly and safely.
- Safety and labeling: Always read the label for safety precautions, pet and child exposure guidelines, and any region-specific cautions to avoid turf damage.
- Long-term maintenance: Consider products offering extended weed prevention (up to 6 months) to reduce seasonal labor and ensure ongoing turf health.
