Bermuda grass is a nitrogen hog that demands precise feeding during its peak growing season. One wrong bag can push a flush of thin, weak blades or leave the turf hungry before summer ends. The difference between a carpet of deep green and a patchy yard is picking a formula built for aggressive warm-season growth.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. My research focuses on comparing NPK ratios, release technologies, and micronutrient profiles while sifting through aggregated owner feedback to find what actually delivers for Bermuda.
This guide breaks down the top granular and liquid options that match the unique physiology of Bermuda grass. Whether you’re looking for a single-season solution or a slow-release program, here’s everything you need to find the best bermuda fertilizer.
How To Choose The Best Bermuda Fertilizer
Bermuda grass has a unique metabolism — it feeds heavily from late spring through early fall, then goes dormant in winter. Picking a product means matching the release timing and nutrient profile to that active window. Here are the three most critical factors to judge.
Nitrogen Source and Release Speed
The first NPK number is everything. Bermuda needs a nitrogen-dominant formula — look for a first number of 16 or higher. Fast-release urea gives a quick green-up within days, but it also raises the risk of foliar burn if applied during a dry spell. Slow-release nitrogen such as polymer-coated sulfur-coated urea or methylene urea feeds the turf steadily over 8 to 12 weeks, avoiding surge growth and reducing how often you need to reapply. For most lawns, a blend of 60-70% slow-release and 30-40% quick-release strikes the right balance between immediate color and lasting feed.
Iron and Secondary Nutrients
Bermuda responds visibly to iron. A product with 2-5% iron deepens the green without forcing excessive leaf growth, which reduces mowing frequency. Look also for sulfur, which lowers soil pH and helps the grass uptake nitrogen more efficiently. Micronutrients like manganese and zinc support root density and disease resistance. A lean NPK with quality micronutrients often outperforms a straight high-nitrogen bag on overall turf health.
Granular vs. Liquid Formulation
Granular fertilizers are the traditional choice for larger lawns because they provide longer residual feeding and are easier to spread evenly with a broadcast spreader. Liquids, on the other hand, deliver fast foliar absorption and allow you to target specific nutrient deficiencies within a week. Liquids work especially well for “spoon-feeding” during the hot summer months when Bermuda needs frequent, low-rate nitrogen applications. The best overall program often combines a granular base feed in spring with liquid supplements through the summer.

In‑Depth Reviews
1. PetraMax Neighbor’s Envy
PetraMax combines 19% nitrogen, 2.5% iron, humic acid, sea kelp, potassium, and sulfur into a single liquid concentrate that covers up to 16,000 sq. ft. per gallon. The iron and humic acid work together to darken Bermuda blades without triggering the surge growth that leads to thatch buildup — a common issue with straight urea.
Users report visible greening within 7-14 days, and the blend’s sulfur content helps keep soil pH in the 6.0-6.5 sweet spot. The formula is safe for Bermuda even during peak summer heat because the nutrients are delivered in a foliar-absorbable liquid form that reduces the concentration stress on root systems. PetraMax backs this with a 100% satisfaction guarantee and USA-based customer support.
One factor to note: as a liquid, it requires a sprayer for even coverage — you cannot drop-spread it like granular products. It also ships as a 1-gallon jug, which is heavier than a granular bag of equivalent coverage, though the liquid formulation allows for more precise targeting of thin spots.
What works
- Rich green in 7-14 days with 2.5% iron
- Humic acid and sea kelp improve soil biology
- Safe for pets and children once dry
- Large coverage: 16,000 sq. ft. per gallon
What doesn’t
- Requires a hose-end or tank sprayer
- Lighter-weight jug is a physical challenge for large lawns
2. The Andersons Professional PGF 16-0-8
The Andersons uses ultra-fine DG (Dispersion Granule) technology that breaks down upon contact with moisture, releasing particles evenly across the turf. The 16-0-8 ratio includes quick and slow-release nitrogen sources for immediate feeding plus extended nutrition up to 8 weeks. This phosphorus-free formula is ideal for established Bermuda lawns where soil phosphorus is already sufficient — reducing runoff risk.
Each bag contains Humic DG, a soil conditioner that improves nutrient uptake and microbial activity right in the root zone. Owners note that the fine particle size eliminates the stripe pattern that coarser granules sometimes leave on Bermuda. The iron and micronutrient package (including sulfur and manganese) supports deep green color without forcing the grass into a growth spurt that demands more blade mowing.
The 18-pound bag covers a relatively small area — about 5,000 to 6,000 sq. ft. depending on application rate — which makes it less practical for acreage-sized lawns. It is also not available for shipment to California or Oregon due to regulatory restrictions on certain slow-release compounds.
What works
- Ultra-fine particles eliminate striping on Bermuda
- Humic DG boosts root zone biology
- Phosphorus-free for established turf
- Sustained 8-week feeding with minimal surge
What doesn’t
- Coverage is limited per bag
- Not available in CA or OR
3. Yard Mastery 24-0-6 Flagship Granular
Yard Mastery’s 24-0-6 formulation delivers the highest nitrogen concentration on this list, with a full 24% coming from a mix of quick-release and slow-release sources. The 3% iron content pushes blade color to a deep blue-green that Bermuda enthusiasts prize. The bag also includes boron, copper, manganese, molybdenum, and zinc — a complete micronutrient package that supports metabolic functions beyond just leaf color.
The slow-release portion uses Bio-Nite technology, which relies on natural soil microbes to meter out nitrogen over time. This reduces the risk of nitrogen burn even with the high total nitrogen number. It covers 6,000 sq. ft. per 18-pound bag, which is a standard density for premium granular fertilizers. Many owners report that one application in late spring carries Bermuda through to mid-summer before a second feeding is needed.
One limitation is that the 24% nitrogen heavy formula can still cause foliar burn if applied during a drought period or if the spreader calibration is off. It also lacks potassium below 6%, so Bermuda lawns with high traffic or compaction may need a separate potassium boost later in the season.
What works
- Highest nitrogen count for aggressive Bermuda
- 3% iron for deep blue-green color
- Complete micronutrient blend with 5 trace minerals
- Bio-Nite slow-release reduces burn potential
What doesn’t
- Can burn if spread on dry, stressed turf
- Potassium level is low for high-traffic lawns
4. GreenView Fairway Formula 27-0-5
GreenView’s Fairway Formula packs 27% nitrogen with 63% of it in slow-release form, providing a consistent feed for up to 12 weeks. The 33-pound bag covers a remarkable 10,000 sq. ft., making it the most coverage-efficient granular option for larger Bermuda lawns. The phosphorus-free 27-0-5 ratio is tailored for established turf where phosphate runoff is a concern.
The slow-release nitrogen is polymer-coated, which resists washout during heavy summer thunderstorms — a practical advantage in the humid Southeast where Bermuda thrives. Owners frequently note steady, even greening without the excessive mowing load that fast-release fertilizers can trigger. The 5% potassium supports root depth and overall stress tolerance as Bermuda enters the heat of July.
One issue with a 33-pound bag is physical handling — it is heavy and requires a spreader with good capacity. The granules are also slightly coarser than premium products like The Andersons, so you may notice slight stripes if your spreader pattern is not well calibrated. It works well on all grass types but is optimized for warm-season grasses like Bermuda and Zoysia.
What works
- 12-week slow-release for long-lasting feed
- 10,000 sq. ft. coverage per bag
- Phosphorus-free reduces runoff risk
- Stable in rain after application
What doesn’t
- Heavy 33-pound bag is cumbersome
- Coarser granules may leave spreader stripes
5. Pennington Full Season 32-0-5 4M
Pennington’s Full Season formula uses polymer-coated urea to meter out nitrogen over four months — one application in early spring can feed Bermuda through most of its active growing period. The 32-0-5 ratio is the highest nitrogen number on this list, and the inclusion of 5% iron provides quick visual greening. The formula also contains 0.5% naturally beneficial microorganisms intended to revitalize soil biology.
The coverage is 4,000 sq. ft. per 11.2-pound bag, which is on the lower side per pound compared to larger bags, but the single-application convenience is a strong selling point for homeowners who want to set it and forget it. The polymer coating reduces the risk of nitrogen leaching, making it suitable for sandy soils typical of coastal Bermuda regions. The natural microorganisms in the bag may improve organic matter breakdown over several seasons.
One limitation: the 4-month release window assumes you apply early enough in the season. If you apply later than late spring, the nitrogen may still be releasing when Bermuda is entering dormancy, which can lead to winter kill in colder zones. Also, the inclusion of live microorganisms means the bag should be stored in a cool, dry place to maintain viability.
What works
- Single application feeds for 4 months
- Polymer-coated urea reduces leaching
- 5% iron for rapid greening
- Includes soil microorganisms
What doesn’t
- Late-application risks winter burn
- Limited 4,000 sq. ft. coverage per bag
6. Petra Liquid Nitrogen 28-0-0
Petra’s 28-0-0 liquid nitrogen uses a 2-in-1 release system: 70% quick-release for an instant color boost and 30% slow-release for continued feeding between applications. Each 32-ounce bottle concentrates to treat up to 12,800 sq. ft. at a maintenance rate, or 6,400 sq. ft. for deficiency correction. The high nitrogen concentration works quickly on Bermuda that has yellowed from early-season deficiency.
The liquid formulation allows you to spot-treat thin areas or to tank-mix with other liquid products such as humic acid or seaweed. Users appreciate the ease of application — just mix 5 ounces per gallon of water and spray. The fast action means you can see results within 3-5 days, making it a reliable rescue fertilizer for Bermuda that needs a mid-summer pick-me-up.
Because it is 70% quick-release, applications should be spaced at least 3-4 weeks apart to avoid a growth flush that needs extra mowing. It also requires a sprayer that can handle liquid concentrate without clogging. The 28-0-0 lacks iron and micronutrients, so you may need to supplement with an iron product separately for the deepest color.
What works
- Very fast green-up in 3-5 days
- Treats up to 12,800 sq. ft. per bottle
- Easy spray-on application
- Combination quick/slow release reduces burn
What doesn’t
- No iron or secondary micronutrients
- Requires frequent reapplication for sustained feed
7. Supply Solutions Urea 46-0-0
Supply Solutions delivers straight urea at 46% nitrogen — the most concentrated single-nutrient source here. It is designed as a soil amendment for rapid correction of nitrogen deficiency in turf, trees, and vegetables. Application rates for Bermuda are very low: about 0.2 pounds per 1,000 sq. ft. for turf maintenance, making the 5-pound bag go a long way if you use careful measurements.
Pure urea is highly water-soluble and converts to ammonium quickly in warm soil, so Bermuda absorbs it almost immediately. This makes it effective for post-dormancy green-up in early spring or for spot-feeding after heavy rain leaches existing nitrogen. The minimal ingredient list means no filler, no iron, no potassium, and no slow-release coating — it’s straight nitrogen for those who want total control over their fertilizer mix.
The downside is that 46% nitrogen carries a high burn risk. Even slight overapplication can scorch Bermuda, especially in hot weather. It also offers zero slow-release protection, so you will need to reapply every 3-4 weeks during the growing season. The 5-pound bag is small and suitable for small lawns or for supplementing a broader fertility program, but not for feeding a 10,000 sq. ft. Bermuda lawn alone.
What works
- Highest nitrogen concentration available
- Very cost-effective per pound of N
- Fast-acting for deficiency correction
- Versatile for turf, trees, and veg
What doesn’t
- High risk of burn if misapplied
- No slow-release, needs frequent reapplication
- Lacks iron, potassium, and micronutrients
Hardware & Specs Guide
NPK Ratio Decoded
The three numbers — nitrogen, phosphorus, potassium — are the backbone of any fertilizer. For Bermuda, the first number should be the highest because the grass’s rapid growth cycle demands continuous nitrogen. The second number (phosphate) is often zeroed out to prevent runoff in established lawns. The third number (potassium) supports root strength and stress tolerance; 5-8% is a solid target for northern Bermuda transition zones.
Slow-Release Technology
Polymer-coated urea and sulfur-coated urea are the two main slow-release systems. Polymer coatings release through osmosis, making them more predictable across soil temperatures. Sulfur coatings rely on microbial breakdown and can stall in cool spring soils. Products labeled “4M” or “12-week” use these technologies to extend feeding beyond a single month, reducing the total number of applications needed per season.
