Trade-offs
Some users have noted that it may not be as effective on particularly stubborn or mature weeds, suggesting that multiple applications or a more targeted approach might be needed for severe infestations. It's also important to note that this isn't a pre-emergent, so it focuses on existing weeds.

Scotts Turf Builder Triple Action1 offers a multi-faceted approach to lawn care, aiming to control weeds, prevent crabgrass, and fertilize your grass all in one application. This makes it a compelling option for St. Augustine lawns that are dealing with a variety of issues. Its ability to handle crabgrass pre-emergently is a significant advantage for many homeowners.

Trade-offs

3. Scotts Turf Builder Lawn Food
3. Scotts Turf Builder Lawn Food
For those looking for a straightforward fertilizer to boost their St. Augustine lawn's health without the added weed control chemicals, Scotts Turf Builder Lawn Food is an excellent choice. It focuses on providing essential nutrients to help grass grow thicker and greener naturally. A healthier, denser lawn is often less susceptible to weed invasion, making this a good proactive step.
Why I picked it
This option is a great budget-friendly choice because it focuses solely on fertilizing the lawn, leading to healthier, denser turf that can naturally outcompete many types of weeds. It’s ideal if you prefer to manage weeds separately or have minimal weed issues.
Key specs

Real-world experience

The large coverage area makes it economical for substantial lawns, and it's generally praised for its ease of application.
Trade-offs
As this product is purely a fertilizer, you won't find any weed-killing active ingredients. If your primary concern is actively eliminating broadleaf weeds, this product alone won't solve that problem and would need to be paired with a separate weed killer.

Trade-offs
This product is primarily for visible greening and fertilization; it does not contain herbicides to kill weeds. If your lawn has significant weed problems, you'll need to use a separate weed killer in conjunction with this product. Over-application could potentially lead to temporary staining on surfaces.

How I picked
When selecting the best weed and feed for St Augustine lawns, I focused on a few key criteria. First, I looked for products specifically formulated or known to be safe and effective for St. Augustine grass, as this type can be sensitive to certain chemicals. I evaluated the active ingredients in the weed control component, prioritizing those that target common broadleaf weeds without harming the turfgrass.
Beyond weed control, I considered the fertilizer component, ensuring it provides balanced nutrition for lawn health. Products that offer additional benefits, like crabgrass prevention or enhanced greening, were also noted. I then cross-referenced these with user reviews, looking at reported effectiveness, ease of application, and any noted drawbacks. My aim was to find solutions that offer a good balance of performance, value, and safety for your lawn.
Buying guide — what actually matters for Best Weed And Feed For St Augustine
When you're out shopping for a weed and feed product for your St. Augustine lawn, it's easy to get overwhelmed by all the options. To make the best choice, let's break down what truly matters.
Weed Control Efficacy for St. Augustine Grass
St. Augustine grass can be a bit particular, and not all weed killers are safe for it. You'll want to look for products that explicitly state they are safe for St. Augustine or that list the active ingredients and cross-reference their safety.
Common herbicides like 2,4-D, dicamba, and MCPP are often found in weed and feed products, and their concentration and combination are key to effective weed removal without harming your grass.
Fertilizer Benefits and Nutrient Ratios
A good weed and feed doesn't just kill weeds; it also nourishes your lawn. Look at the N-P-K ratio on the fertilizer bag. For St. Augustine grass, a balanced fertilizer is typically good, but depending on the season, you might want something with a bit more nitrogen for greening or a formulation that encourages root development.
Proper fertilization helps your St. Augustine grow thicker, which naturally crowds out new weeds.
Application Timing and Seasonality
The effectiveness of weed and feed products often depends heavily on when you apply them. For broadleaf weed control, applications are usually best when weeds are actively growing, which often means spring or fall. If the product also includes crabgrass preventer, timing is even more critical, typically needing to be applied before soil temperatures consistently reach 55°F (13°C) for five consecutive days. Always check the product label for specific timing recommendations for your region.
Coverage Area and Value
Consider the size of your lawn. Products are typically sold in bags that cover a specific square footage (e.g., 4,000 sq. ft. or 5,000 sq. ft.). Calculate your lawn's area to ensure you buy enough product without overspending or running short. Generally, larger bags offer better value per square foot, but make sure the product meets your specific needs.
Ease of Application
Most weed and feed products are granular and designed for application with a broadcast or rotary spreader. Ensure you have the right spreader and understand the settings recommended on the product label for even distribution. Over-application can damage your lawn, while under-application can lead to patchy results. Some products might require watering-in after application, so factor that into your process.
Frequently Asked Questions (FAQ)
Is weed and feed safe for St. Augustine grass?
Yes, many weed and feed products are safe for St. Augustine grass, but it's crucial to read the product label carefully. Some herbicides can harm St. Augustine, especially when applied at higher temperatures or incorrect dosages.
Look for products explicitly stating their safety for St. Augustine or that contain specific, safe active ingredients. Always follow application instructions precisely.
When is the best time to apply weed and feed to St. Augustine grass?
The ideal time for applying weed and feed to St. Augustine grass is typically when the weeds are actively growing and the grass has started its active growth cycle. This is often in the spring. For products containing pre-emergent herbicides like crabgrass preventer, application should occur before soil temperatures consistently reach 55°F (13°C) for five consecutive days, usually in late winter or early spring.
Fall applications can also be beneficial for controlling later-season weeds and preparing the lawn for dormancy.
How long does it take for weed and feed to work?
You can usually expect to see results from weed and feed products within about 7 to 14 days. The weed killer component needs time to be absorbed by the weeds and take effect, causing them to wilt and die. The fertilizer component begins to work immediately, providing nutrients to the grass. For best results, follow the application and watering instructions on the product label.
Can I use weed and feed if I have pets or children?
Pet and child safety is a major concern for many homeowners. After applying weed and feed, it's generally recommended to keep pets and children off the treated lawn until the product has been watered in or dried completely, according to the product's instructions. Some products may require a longer waiting period for re-entry, so always check the label for specific safety precautions and waiting times.
What's the difference between a weed and feed and just fertilizer?
A fertilizer, like Scotts Turf Builder Lawn Food, provides essential nutrients (nitrogen, phosphorus, potassium) to promote healthy grass growth, leading to thicker, greener turf. A weed and feed product does that too, but it also contains active ingredients (herbicides) specifically designed to kill unwanted weeds like dandelions, clover, and other broadleaf invaders. Think of fertilizer as food for your lawn, and weed and feed as food plus medicine for when weeds are present.
Final verdict
For St. Augustine lawns in need of both weed control and nourishment, Scotts Turf Builder Weed and Feed 3 stands out as our top choice, offering a reliable combination of active ingredients to tackle common weeds while feeding your grass to promote density and health. If you're looking for a multi-action product that also helps prevent crabgrass before it germinates, Scotts Turf Builder Triple Action1 is an excellent, albeit slightly more season-specific, alternative. For those prioritizing a simple, budget-friendly fertilization that encourages a healthier, naturally weed-resistant lawn, Scotts Turf Builder Lawn Food is a solid pick.
