Best Slow Release Fertilizer For Bermuda Grass

#1 · Best Overall

1. Pennington Full Season Fertilizer

• Form: Granules
• Weight: 11.2 lb

Best for: Long-interval bermuda feeding.

Why it ranks #1: Its verified compatibility list names Bermudagrass, and polymer-coated urea supplies controlled-release nitrogen for up to four months.

Polymer-coated urea releases nitrogen for up to four months in Pennington Full Season Lawn Fertilizer, enabling a single application to feed for a season. Its verified use list specifically includes Bermudagrass, making this the clearest match here for buyers seeking extended-release feeding on that turf type.

The slow-release nitrogen supports growth and greening over an extended interval, while 5% iron promotes deep green color. Pennington also includes beneficial microorganisms intended to revitalize soil, adding a soil-care element to the fertilizer’s feeding role. Application is by spreader according to package directions. Coverage depends on bag size, with options for up to 4,000 or 12,000 square feet, so buyers can match the selected size to their lawn area.

Skip it if you live in Hawaii or South Dakota; the supplied product information says this fertilizer is unavailable in those states.

This suits bermuda owners who want one spreader application to carry feeding across a season, with iron for color. Check the bag’s coverage option against your lawn area, and note that it is unavailable in Hawaii and South Dakota.

#2 · Longest Listed Feed

2. GreenView Fairway Formula Lawn Fertilizer

• Form: Granules
• Weight: 33 lb

Best for: Extended feeding for larger lawns.

Why it ranks #2: The formula has 63% slow-release nitrogen, feeds for up to 12 weeks, and is verified for use on all grass types.

GreenView Fairway Formula’s 63% slow-release nitrogen feeds for up to 12 weeks, enabling extended nutrition with even growth rather than surge patterns. The 33-pound bag covers 10,000 square feet, making it a practical scale match for larger bermuda lawns needing sustained feeding.

The formula combines immediate-release and controlled-release nutrition, so it pairs an initial response with feeding that continues for up to 12 weeks. GreenView says it can be used on all grass types and any time turf is actively growing, giving bermuda owners flexibility beyond the commonly used spring application. Its coverage of up to 10,000 square feet can simplify treating a larger lawn with one bag. The supplied information says it is ideal when weed or crabgrass control is not needed.

Skip it if you need fertilizer that also addresses weeds or crabgrass; this product is specified for lawns without those control needs.

This is a fit for bermuda owners with larger lawns who want extended feeding during active growth. Its 10,000-square-foot coverage and lack of weed or crabgrass control are important considerations for matching it to your yard.

#3 · Highest Slow-Release Share

3. AgChimp Professional Lawn Fertilizer

• Form: Granules
• Weight: 16 lb

Best for: Controlled nitrogen for steady growth.

Why it ranks #3: Its formula contains 30% slow-release nitrogen with polymer-coated particles, plus quick-release nitrogen for an immediate green-up.

AgChimp’s dual-phase feeding combines quick-release nitrogen for rapid green-up with polymer-coated nitrogen for gradual nutrition. That approach enables both an early color response and more controlled ongoing growth, making this 24-0-11 granular fertilizer an option for bermuda owners seeking sustained feeding.

The product description identifies 30% slow-release nitrogen, and its coated particles are intended to provide gradual, consistent nutrition without growth spikes or excessive top growth. That pairing with quick-release nitrogen supports both quicker green-up and longer-term feeding in one application. The stated outcome is a denser, resilient lawn structure, while potassium is part of the 24-0-11 analysis. Its listed common residential grass use is the relevant scope for buyers evaluating it for bermuda.

Skip it if you need phosphorus in the fertilizer analysis; The Andersons PGF Complete 16-4-8 includes phosphorus in its listed formula.

This suits bermuda owners seeking quick green-up paired with controlled nitrogen release and gradual feeding. Its 24-0-11 analysis has no phosphorus, so consider that limitation when choosing a fertilizer for your lawn’s needs.

#4 · Humic-Enhanced Feed

4. Andersons PGF Complete

• Form: Granules
• Weight: 18 lb

Best for: Fine-particle growing-season feeding.

Why it ranks #4: It combines quick- and slow-release nitrogen for up to eight weeks with iron, micronutrients, and Humic DG; it is safe for all turf types.

Super-fine particles provide twice the number of particles per square foot in The Andersons PGF Complete 16-4-8, enabling even distribution. Its quick- and slow-release nitrogen then combines immediate feeding with extended nutrition for up to eight weeks, making it a growing-season option for bermuda lawns.

The 16-4-8 formula supplies a 4-1-2 ratio alongside iron, micronutrients, and Humic DG, so its stated nutrition extends beyond nitrogen alone. Quick- and slow-release nitrogen supports both immediate feeding and nutrition for up to eight weeks; the product guidance recommends reapplication every six to eight weeks for best results. It is listed as safe for all turf types and usable any time during the growing season, making it applicable to bermuda within those stated boundaries.

Skip it if you are in California; The Andersons Premium Fall Lawn Food 24-0-14 is another listed turf fertilizer option.

This is a fit for bermuda owners seeking an all-season growing-period formula with fine particles and mixed-release nitrogen. Its feeding interval calls for attention to reapplication, and it is not for sale in California.

#5 · Natural Formula

5. O.M. Scott Natural Grass Food

• Weight: 12.7 lb

Best for: Natural feeding with watering routine.

Why it ranks #5: This natural grass food feeds for up to 10 weeks when watered immediately after application, though the supplied facts do not name Bermuda grass.

O.M. Scott & Sons Natural Grass Food begins feeding immediately when watered after application and continues for up to 10 weeks. That combination enables a natural lawn-food routine with an extended interval, suited to bermuda owners willing to finish spreading with a light watering.

The product is described as made with nutrient sources found in nature and as containing no added artificial ingredients or pesticides. Its listed routine uses a Scotts spreader set according to the bag, followed by immediate watering; that step activates the stated immediate feeding. Continued feeding can last up to 10 weeks, and directions say to feed every eight to 10 weeks, up to four times a year. The product information also states that people and pets can reenter immediately after application.

Skip it if you do not want to water after spreading; Scotts WinterGuard can be applied to a wet or dry lawn in fall.

Choose this for bermuda owners who want a natural lawn-food option and can water immediately after spreading. Its feeding interval is up to 10 weeks, with directions calling for repeat feeding every eight to 10 weeks.

#6

6. Milorganite 6-4-0 Fertilizer

• Form: Pelletized
• Weight: 32 lb

Best for: Low-salt feeding for hot conditions.

Why it ranks #6: Its low-salt formula is described as helping avoid streaks and fertilizer burn in hot or dry conditions, and it includes iron for greening.

Milorganite’s low-salt formula is intended to help avoid streaks, stripes, and fertilizer burn, including in hot or dry conditions. Paired with organically complex iron for deep green color, it offers bermuda owners a pelletized feeding option whose stated benefits address application appearance and heat-related concerns.

The 32-pound bundle includes Milorganite 6-4-0 fertilizer and a printed brochure with seasonal application and spreader guidance, giving buyers both product and reference material. Its low-salt formula is described as helping avoid streaking and burn, while organically complex iron greens the lawn without staining concrete like iron salts in some synthetic fertilizers. The product contains heat-dried microbes. Its earthy aroma after application should dissipate within a few days; rain or watering can help reduce it.

Skip it if you want a product explicitly listing polymer-coated nitrogen release for months; Pennington Full Season 32-0-5 feeds for up to four months.

This fits bermuda owners who value low-salt feeding and iron for lawn color, particularly in hot or dry conditions. Be prepared for an earthy aroma after application, and use the included brochure for seasonal and spreader guidance.

#7

7. Spectracide Lawn Fertilizer

• Form: Liquid

Best for: Hose-end liquid lawn feeding.

Why it ranks #7: The liquid 30-0-0 formula combines quick- and slow-release nitrogen and uses a hose-end sprayer, but the data do not specify Bermuda compatibility.

The QuickFlip hose-end sprayer applies Spectracide Lawn Fertilizer without mixing, enabling a direct connect-and-spray routine. Its 2-in-1 formula pairs quick-release nitrogen for fast greening with slow-release nitrogen for longer-lasting color, offering bermuda owners a liquid alternative to granular spreading.

The liquid fertilizer’s 30-0-0 analysis and dual-release nitrogen are intended to boost lawn strength, support deep roots, and provide both fast color and lasting color. Application uses the included QuickFlip hose-end sprayer: connect it to a hose and spray, with no mixing required. Each 32-ounce bottle feeds up to 5,000 square feet according to the product information. Application timing is subject to local restrictions, including stated winter limits in parts of Florida and New York.

Skip it if you cannot apply during local restricted periods; check the listed north Florida winter and New York State dates before using this formula.

This suits bermuda owners who prefer a hose-end liquid application and want quick color with continued release. Account for the stated regional seasonal restrictions, and match the up-to-5,000-square-foot bottle coverage to your lawn.

#8

8. Andersons Premium Fall Lawn Food

• Form: Granules
• Weight: 18 lb

Best for: Fall feeding with iron and potash.

Why it ranks #8: It is safe for all turf types and combines quick-, intermediate-, and slow-release nitrogen, but its stated purpose is fall lawn preparation.

Three nitrogen release speeds—quick, intermediate, and slow—give The Andersons Premium Fall Lawn Food a fast green-up alongside extended feeding. Its 24-0-14 formula also includes iron and potash, connecting fall lawn nutrition with color and preparation for winter on bermuda turf.

This product is Application 4 in The Andersons Lawn Program and is intended to feed and prepare a lawn for winter. Its quick, intermediate, and slow-release nitrogen supports both faster greening and continued feeding, while iron aids chlorophyll development and helps prevent yellowing for deep green color. Potash is described as helping thicken grass wall structure and promote hardiness. The product is listed as safe for all turf types, which includes bermuda within its stated scope.

Skip it if you need a growing-season formula rather than fall preparation; The Andersons PGF Complete 16-4-8 can be used during the growing season.

This fits bermuda owners seeking a fall application that combines multiple nitrogen release speeds with iron and potash. It is Application 4 in a lawn program, so its seasonal role is the key fit consideration.

#9

9. GreenView Fairway Formula Fall Fertilizer

• Form: Granules

Best for: Even fall greening without surge.

Why it ranks #9: This fall formula supports deep roots and steady greening on any grass type, but its seasonal focus makes it less versatile for active-season feeding.

Steady, even greening without surge growth is GreenView Fairway Formula Fall Lawn Fertilizer’s clearest distinction. Its fall-focused formula is intended to repair summer damage, prepare lawns for winter, and encourage deep roots, making it a seasonal option for bermuda owners prioritizing controlled-looking growth over a rapid flush.

GreenView says the granular fertilizer works on any grass type, so bermuda is included in its stated use. Its fall lawn-care role connects summer-damage repair with winter preparation and better spring growth, giving the application a seasonal purpose beyond color alone. The product also emphasizes deep roots and thick, lush growth while avoiding surge growth. Safety directions say not to hand spread, so application requires a suitable spreader rather than broadcasting it by hand.

Skip it if you want a single spring application feeding for months; GreenView Fairway Formula 2129188 feeds for up to 12 weeks.

Choose this for a bermuda lawn needing fall recovery and pre-winter preparation, especially if avoiding surge growth matters. It is a seasonal product, and its directions rule out hand spreading, so plan on using a spreader.

#10

10. Scotts Turf Builder WinterGuard

• Form: Granules
• Weight: 8 oz

Best for: Fall root-prep for small lawns.

Why it ranks #10: It can be used on any grass, but its stated purpose is fall feeding for root development and winter preparation rather than routine slow-release feeding.

Fall feeding is the focus of Scotts Turf Builder WinterGuard: it builds strong, deep grass roots while helping lawns recover from summer heat, drought, and activity. That seasonal role makes it useful for preparing a lawn for winter and supporting better growth the following spring.

The granules can be applied to a wet or dry lawn in fall, giving homeowners flexibility around watering conditions on application day. Scotts identifies use on any grass, so bermuda grass is within its stated scope. The product is also intended for smaller yards and can be applied with a Scotts spreader, with listed settings for broadcast/rotary and drop spreaders. Light watering can speed results, but watering in is not required.

Skip it if you need feeding during active summer growth; Pennington Full Season 32-0-5 releases nitrogen for up to four months.

This is a fit for bermuda owners doing fall lawn preparation who want root-focused feeding after summer stress. Keep its seasonal role in mind: the supplied directions call for fall application, not a recurring warm-season schedule.
