Best Weed and Feed for Bermuda and St. Augustine Lawns
The best weed and feed for a lawn containing Bermuda or St. Augustine is one whose label specifically permits use on that grass type. BioAdvanced and Jonathan Green list both grasses; Ferti-lome’s St. Augustine formula explicitly says not to use it on Bermuda. Scotts and Sunniland may suit some Southern-lawn needs, but check each product label for your exact grass before applying. The comparison below highlights the intended turf, weed-control details, and important cautions.
| Product | Best suited for | Key distinction |
|---|---|---|
| BioAdvanced 3-in-1 | Bermuda and St. Augustine | Lists weed prevention for up to six months |
| Jonathan Green Veri-Green | Bermuda and St. Augustine | 30-0-3 fertilizer and over 40 listed broadleaf weeds |
| Scotts Turf Builder Bonus S | Southern lawns; verify grass label | Feeds grass and targets listed weeds |
| Ferti-lome St. Augustine Weed & Feed | St. Augustine, not Bermuda | 15-0-4 fertilizer; pre- and post-emergent control |
| Sunniland St. Augustine Weed & Feed | St. Augustine lawns | Granules intended for St. Augustine grass |
BioAdvanced 3-in-1 Southern Lawn Granules
Best for: Homeowners who need one product that lists both Bermuda and St. Augustine among its intended Southern lawn grasses. It combines weed control, prevention, and lawn feeding, according to the product details.
The granules target listed broadleaf weeds such as dandelion, dollarweed, and clover. The product states that one application can prevent listed weeds for up to six months. Its directions specify applying when temperatures are between 50 and 90 degrees and weeds are actively growing.
Why it was selected: Its stated suitability for both grass types makes it a direct match for this search. Caution: Weed prevention applies to listed weeds, not necessarily every weed; check the label for the exact species and application directions.
Jonathan Green Veri-Green Southern Weed And Feed
Best for: Buyers seeking a Southern-lawn formula that names both Bermuda and St. Augustine, along with Zoysia and Centipede. Its listed 30-0-3 fertilizer blend is intended to promote greening and dense growth.
The product states that it controls over 40 broadleaf weeds, including dollarweed, dandelion, white clover, spotted spurge, and henbit. It is a post-emergent treatment, so the listed directions focus on actively growing weeds in spring or fall.
Why it was selected: It identifies both target grasses and provides a named weed list, making it useful for comparing turf compatibility and weed targets. Caution: Because this is a post-emergent product, it should not be treated as a substitute for pre-emergent weed prevention.
Scotts Turf Builder Bonus S Southern Weed & Feed
Best for: Shoppers comparing a Southern weed-and-feed product that targets dollarweed, clover, and other listed lawn weeds while feeding grass. The product details also say it helps build strong, deep roots to strengthen grass against heat and drought.
Why it was selected: Its combination of weed control and fertilizer addresses two common lawn-care tasks, and the stated root-strengthening benefit is relevant in hot Southern conditions.
Caution: The supplied product information does not identify Bermuda or St. Augustine as approved grasses. Check the current package label before using it on either grass; do not assume that “Southern” means suitable for every warm-season turf.
Ferti-lome St. Augustine Weed & Feed
Best for: St. Augustine lawns needing a product that combines pre-emergent and post-emergent weed control with a 15-0-4 fertilizer mix. The listed suitable grasses also include Centipede and Zoysia.
Why it was selected: It clearly describes its turf targets and offers both pre- and post-emergent weed control, which distinguishes it from products described only as post-emergent.
Important caution: The product information specifically says not to use it on Bermuda grass or Northern grasses. Choose it only for a lawn whose grass type is permitted by the label.
Sunniland St. Augustine Weed & Feed
Best for: Buyers with St. Augustine grass looking for easy-to-handle granules. The product information says it can be used on all types of St. Augustine grass and describes two applications, in spring and fall.
Why it was selected: Its stated turf-specific use makes it a relevant alternative for St. Augustine owners comparing seasonal application plans.
Caution: Bermuda grass is not listed as suitable in the supplied details. Do not apply it to Bermuda unless the product label explicitly permits that use; confirm timing and application directions on the package.
Buying Guide: How To Choose Weed And Feed
Is the product labeled for your grass?
Start with turf compatibility, not the weed list or fertilizer numbers. For a lawn containing both Bermuda and St. Augustine, select a product whose label permits both. If the yard has separate grass areas, use products only on the grass types specified by their labels. Ferti-lome’s provided information expressly rules out Bermuda.
Which weeds do you need to control?
Match the product’s listed weeds to the weeds growing in your lawn. BioAdvanced names dandelion, dollarweed, and clover; Jonathan Green lists more than 40 broadleaf weeds, including dollarweed, dandelion, clover, spurge, and henbit. A weed-and-feed product may not control every weed, so verify the label’s target list.
Do you need pre-emergent or post-emergent control?
Post-emergent products target weeds that are already growing. Pre-emergent control is intended to prevent listed weeds from establishing. Ferti-lome describes both types of control, while Jonathan Green is described as post-emergent. BioAdvanced states that it can prevent listed weeds for up to six months, subject to its label directions.
When should you apply it?
Follow the product label for temperature, lawn condition, watering, and application rate. BioAdvanced specifies temperatures between 50 and 90 degrees and actively growing weeds. Do not infer that timing applies to the other products. Avoid using a product outside its stated directions simply because weeds are present.
Frequently Asked Questions
Can I use the same weed and feed on Bermuda and St. Augustine?
Only if the product label permits both grass types. BioAdvanced and Jonathan Green list both in the supplied product details. Confirm current package directions before applying.
Is Ferti-lome St. Augustine Weed & Feed safe for Bermuda?
No. Its product information specifically says not to use it on Bermuda grass.
Does “Southern” mean a product is safe for St. Augustine?
Not necessarily. Check the label for St. Augustine by name and follow any restrictions. Regional wording alone does not establish grass compatibility.
Should I use weed and feed if I do not know my grass type?
Identify the grass first or ask a local lawn-care professional. Applying a product to an unlisted grass can risk damage, and the supplied products do not all share the same turf permissions.
