Bermuda grass lawns demand a two-phase strategy: aggressive feeding during the growing season and precise weed suppression that won’t harm the turf’s spreading stolons. The wrong combination leaves you with bare patches or weeds that outcompete your grass for nitrogen.
I’m Rikta — the co-founder and writer behind Gadgets Feed. For years I’ve analyzed granular NPK ratios, pre-emergent timing windows, and iron-chelated formulas to separate effective lawn products from overpriced nitrogen bombs. (And Homer 🐱 supervised from the warm driveway concrete during every spreader calibration test).
This guide compares seven dedicated products so you can confidently choose the right bermuda grass fertilizer and weed killer for your yard size, weed pressure, and seasonal schedule.
How To Choose The Best Bermuda Grass Fertilizer And Weed Killer
Bermuda grass is a warm-season turf that thrives on high nitrogen and consistent mowing. A combined weed-and-feed product lets you address two tasks in one pass, but only if the herbicide is safe for Bermuda stolons and the fertilizer matches the season. Focus on three criteria before opening your spreader.
NPK Ratio and Nitrogen Source
Bermuda grass needs a nitrogen-heavy ratio — look for a first number between 20 and 30. Slow-release nitrogen (often listed as polymer-coated or sulfur-coated) provides steady feeding for 8 to 12 weeks without surge growth that stresses the lawn. Avoid high phosphorus unless a soil test confirms a deficiency; most Bermuda turf prefers a middle number of 0 or 1.
Weed Spectrum and Application Timing
A quality weed-and-feed product must list at least dandelion, clover, chickweed, and crabgrass on its label. Pre-emergent formulas stop weed seeds from germinating in early spring, while post-emergent formulas kill visible broadleaf weeds during active growth. Some granular products combine both, but the timing of your single application matters — apply too late and the pre-emergent window is gone.
Coverage Rate and Particle Size
Check the square-foot coverage on the bag to avoid under-dosing. Fine particle granules deliver more particles per square inch, which improves herbicide contact with weed leaves. Liquid hose-end sprays offer spot-treatment flexibility but require more frequent reapplication. Measure your lawn area before purchasing to match bag size to yard size without leftover waste.

In‑Depth Reviews
1. Sunday Weed & Green 32 oz
Sunday’s Weed & Green uses chelated iron (FeHEDTA) as its active weed-control mechanism rather than a traditional synthetic herbicide. This iron-based approach turns weeds yellow within days while simultaneously deepening the green color of your Bermuda grass — a dual action that saves you a separate iron treatment pass.
Coverage is limited to 1,250 square feet per 32-ounce bottle, making it best suited for small to medium lawns or targeted spot treatments. The included hose-end sprayer mixes the concentrate automatically, though the squeeze-bottle design required extra effort on some units to get the liquid flowing. Several users reported fast wilting of dandelion and oxalis but noted larger, established weeds needed a follow-up application.
The formula also suppresses common lawn diseases like dollar spot and rust without the harsh odor of synthetic herbicides. If you want a low-toxicity option that still delivers visible weed kill and iron green-up, this is the most balanced single-bottle solution for Bermuda grass in the current lineup.
Why it’s great
- Iron-based formula greens turf while killing weeds
- Suppresses dollar spot and snow mold
- No mixing required; attaches directly to hose
Good to know
- Coverage limited to 1,250 sq ft per bottle
- Large, established weeds may need multiple treatments
- Liquid can stain patios or siding if oversprayed
2. Jonathan Green Veri-Green Weed and Feed 21-0-3
Jonathan Green’s Veri-Green delivers a 21-0-3 NPK ratio that matches Bermuda grass’s nitrogen appetite while keeping phosphorus at zero — perfect for established lawns where phosphorus runoff is a concern. The fine particle size improves coverage uniformity, helping the post-emergent herbicide reach more weed surfaces per square foot.
The 15-pound bag covers 5,000 square feet and releases nutrients gradually for up to three months. Users consistently reported that dandelions and chickweed disappeared within two weeks, though some creeping Charlie and wild onion required a second application later in the season. The granular format works best with a rotary spreader set to a medium flow rate — avoid drop spreaders on steep slopes to prevent streaking.
This product cannot be applied at the same time as seeding, so plan a 4-week gap between overseeding and weed-and-feed application. For the price per square foot, Jonathan Green offers one of the most consistent weed kill rates on the market for Bermuda grass lawns under half an acre.
Why it’s great
- 21-0-3 ratio tailored for warm-season grasses
- Controls over 250 broadleaf weeds
- Fine particles for even distribution
Good to know
- Cannot be used during overseeding
- Not effective on all grassy weeds
- Requires a spreader for even application
3. GreenView Fairway Formula 27-0-5
GreenView’s Fairway Formula uses 63% slow-release nitrogen to feed Bermuda grass for up to 12 weeks without the surge-and-fade pattern common with fast-release fertilizers. The 27-0-5 analysis provides the highest nitrogen concentration in this lineup, making it ideal for the peak growing season when Bermuda grass demands frequent feeding.
The 33-pound bag covers a full 10,000 square feet, which suits medium-to-large lawns that need a single spring application to carry through summer. Users noted that the grass turned a deeper green within days and stayed thick without excessive clipping volume. The no-phosphate formula helps protect nearby waterways, an important consideration for lawns bordering ponds or drainage areas.
This product focuses on feeding rather than weed control — it contains no herbicide. If your lawn has significant weed pressure, pair the Fairway Formula with a separate post-emergent spray or use it during periods when weeds are already under control. For pure, sustained nitrogen delivery, this is the most efficient granular feed in the roundup.
Why it’s great
- 63% slow-release nitrogen for 12 weeks of feeding
- Phosphate-free to protect waterways
- High 27-0-5 ratio matches Bermuda grass needs
Good to know
- No herbicide — requires separate weed control
- 33 lb bag is heavy for hand-spreading
- Not ideal for fall application on Bermuda
4. Scotts Turf Builder WinterGuard Fall Weed & Feed3
Scotts formulated WinterGuard specifically for fall application, aiming to strengthen Bermuda grass root systems before dormancy while clearing out late-season broadleaf weeds. The granular mix kills over 50 listed weeds, including clover, dandelion, plantain, and morningglory, and works best when temperatures are between 60°F and 90°F.
The 11.43-pound bag covers 4,000 square feet, making it a compact option for smaller Bermuda lawns. User feedback consistently praised its clover elimination — multiple reviewers saw clover wilt within two weeks. One caution: applying with an inconsistent spreader caused dead streaks where the granule concentration was too high, so walk at a steady pace and overlap wheel tracks by half.
WinterGuard is compatible with Bermuda, Bahia, centipede, fescue, and zoysia, but avoid using it on Floratam St. Augustine. For a targeted fall cleanup that preps your Bermuda lawn for a strong spring comeback, this Scotts product delivers reliable weed kill in a single seasonal pass.
Why it’s great
- Designed for fall root strengthening
- Kills over 50 broadleaf weed species
- Compatible with multiple warm-season grass types
Good to know
- Not intended for spring or summer use
- Spread streaks may occur with uneven distribution
- Covers only 4,000 sq ft per bag
5. Sunday Weed & Green + Liquid Lawn Kickstart Kit
Sunday’s spring kit separates weed control and feeding into two sequential steps, which is smarter than combining both in one pass. The Weed & Green bottle (32 oz, chelated iron formula) kills visible broadleaf weeds and greens the grass. The Lawn Kickstart bottle (22-0-2 liquid fertilizer with iron) delivers nitrogen and potassium for deeper root growth — applied one week after the weed treatment.
Coverage reaches up to 4,000 square feet total, and the included hose-end sprayers make each step a 15-minute job. Users reported that dandelions and clover wilted within 24 to 48 hours, while the fertilizer produced visible green-up in three to four days. The separation means you reduce total pesticide use — you only treat weeds where they exist rather than blanketing herbicide across the entire lawn.
Some reviewers with large, weed-infested lawns needed more product to achieve full control, and the iron content can stain concrete if overspray isn’t rinsed immediately. For a thoughtful spring rebuild that prioritizes weed removal before feeding, this kit earns its premium status for Bermuda grass owners who want precision rather than guesswork.
Why it’s great
- Separates weed kill from fertilization for better results
- 22-0-2 fertilizer with iron for fast green-up
- Reduces overall pesticide use on your lawn
Good to know
- Larger lawns may require multiple kits
- Iron can stain patios and siding
- Tough weeds need a follow-up application
6. Scotts Liquid Turf Builder with Plus 2 Weed Control (2-pack)
Scotts Liquid Turf Builder with Plus 2 delivers a quick nitrogen boost and broadleaf weed control in a single hose-end bottle. The two-pack covers up to 6,000 square feet for warm-season lawns like Bermuda, making it one of the most economical liquid options for mid-sized yards. Each 32-ounce bottle attaches directly to your garden hose with no mixing or measuring.
The formula targets buckhorn, chickweed, ground ivy, henbit, oxalis, pigweed, plantain, poison ivy, ragweed, and spurge — plus dandelions and clover. Users saw weeds wilting within 4 to 5 days, with full control lasting several months. The quick-release nitrogen delivers an immediate green-up, but the feeding effect is shorter-lived than slow-release granular options, so plan a follow-up application in 4 to 6 weeks during peak growing season.
Some weeds like nutsedge are not controlled by this formula, and the hose-end connection took a few tries to get a proper seal on some garden hoses. If you prefer the speed of liquid application and have moderate weed pressure, this two-pack offers the best cost-per-square-foot among the liquid options.
Why it’s great
- Covers 6,000 sq ft per two-pack — great value
- Fast visible weed kill within 4-5 days
- No mixing; hose-end applicator included
Good to know
- No control over nutsedge or grassy weeds
- Nitrogen effect is shorter than slow-release granules
- Hose connection may require careful attachment
7. The Andersons Professional Surge 16-0-9
The Andersons Professional Surge is a 40-pound granular bag that covers 16,000 square feet — the largest coverage area in this comparison. The 16-0-9 ratio provides moderate nitrogen with a 4-way herbicide blend that eliminates over 250 common broadleaf weeds including dandelions, clover, chickweed, and plantain. It is designed for entire growing season use and performs well even in the cooler temperatures of spring and fall.
Users reported excellent creeping Charlie control, a weed that many other products struggle to suppress. The fine particle size ensures more particles per square inch for improved herbicide contact. One reviewer noted that zoysia grass thickened nicely after application, though control of some broadleaf weeds was not as complete as expected — a second application may be needed for heavy infestations.
This product is not for use on Floratam St. Augustine, dichondra, carpetgrass, or creeping bentgrass, and it is not sold in New Hampshire or Washington. For large Bermuda lawns with persistent broadleaf pressure, the Professional Surge delivers the most square footage per bag and a herbicide list that covers nearly every common lawn weed.
Why it’s great
- Massive 16,000 sq ft coverage per bag
- Kills over 250 broadleaf weed species
- Fine particles improve herbicide contact
Good to know
- Not compatible with Floratam St. Augustine
- 40 lb bag is heavy to carry and load
- Some weed species may need a second application
