BioAdvanced 3-in-1 Weed And Feed For Southern Lawns, Granules
This granule-based product targets Southern lawn types, including Bermudagrass and St. Augustinegrass (Floratam). It combines weed control with fertilization, offering up to six months of weed prevention. It kills common lawn weeds such as dandelion, dollarweed, and clover while feeding the lawn to promote healthy growth. Suitable for active weed-prone southern climates, it supports a green, dense turf when applied according to label directions.
Spectracide Weed & Feed 20-0-0 Ready-To-Spray
Spectracide’s ready-to-spray formula provides a dual-action approach: it both feeds the lawn with a 20 percent nitrogen formulation and kills broadleaf weeds. This option is convenient for spot treatments or larger areas, delivering broadweed control like dandelion, chickweed, knotweed, plantain, and clover while supporting turf health. It is designed for common turfgrass varieties and can be used where lawn grasses are present, following label directions for safe application.
BioAdvanced 3-in-1 Weed And Feed For Southern Lawns, Granules, 20 lb
This larger granule bag extends the same 6-month weed prevention and broadweed killing features as the 10 lb variant, but with more product for bigger lawns. It targets Southern lawn species such as Bermudagrass and Floratam St. Augustine, offering a balanced approach to weed management and fertilization. Follow label directions for application rates based on lawn size to maximize effectiveness and minimize potential runoff.
Fertilome (13917) St. Augustine Weed & Feed 15-0-4
Fertilome’s St. Augustine Weed & Feed is formulated for Centipede, Zoysia, and St. Augustine lawns, with a 15-0-4 fertilizer blend. It provides pre-emergent and post-emergent weed control, helping to suppress intrusive annual weeds while delivering essential nutrients. It is not suitable for Bermuda grasses, so users should confirm their lawn type before applying and follow application timing recommendations to optimize weed control and turf health.
BioAdvanced 5 In 1 Weed And Feed, Granules, 9.6LB
This five-in-one formulation targets tough weeds while feeding the lawn and preventing new growth. It is designed to address crabgrass and other common weeds, providing visible results in a relatively short timeframe. As with any weed-and-feed product, lawn type compatibility and timing are important to maximize effectiveness and minimize potential damage to desirable grasses. Always follow label directions for best results.
Buying Guide: Key Purchase Considerations
When selecting a weed and feed product, consider the following factors to match your lawn’s needs:
- Lawn Type Compatibility: Confirm whether the product is formulated for Southern grasses (like Bermudagrass or St. Augustine) or general turf varieties. Some blends are species-specific and may harm certain grasses.
- Weed Spectrum: Review which weeds are labeled as controlled, including broadleaf weeds (dandelion, clover) or grassy weeds (crabgrass). Some formulas emphasize pre-emergent protection, others focus on post-emergent control.
- Feeding Schedule: Look for products with prolonged weed prevention (up to six months) or immediate nutrient delivery. Longer protection reduces maintenance frequency but requires precise timing.
- Application Form: Granules are useful for slow-release feeding, while ready-to-spray options offer quick, uniform coverage. Choose based on lawn size and ease of use.
- Environmental Considerations: Avoid applying during extreme heat, drought, or right before heavy rainfall to minimize runoff and turf stress. Follow label directions for safe handling and storage.
- Safety and Re-entry: Check re-entry intervals for treated areas, especially in homes with children or pets. Adhere to recommended mowing schedules after application.
- Lawn Health Goals: If your priority is broad weed suppression with fertilizer, pick a product labeled for weed prevention. If rapid growth is desired, prioritize higher nitrogen content and fast-acting weed control.
- Geographic Relevance: Southern lawn formulations often address Floratam St. Augustine and Bermudagrass, while others are suitable for mixed lawns across regions. Ensure the product aligns with your climate zone.
How to Apply Effectively
Proper application maximizes weed control and turf health. Read the label for correct application rates, watering needs, and timing related to seasonal growth. For granular products, apply evenly and water lightly after spreading to activate the granules. For spray formulations, calibrate equipment to avoid over-application and protect non-target plants. In all cases, avoid mowing immediately before or after treatment unless specified by the label, and store products away from children and pets.
