Georgia Lawn Fertilization Guide

Liquid vs. Granular Lawn Fertilizer

Both liquid and granular fertilizers can support a healthy lawn. The better choice depends on the nutrient source, grass type, season, application method, and condition of the turf.

Start With the Lawn's Needs

Which Type of Fertilizer Is Better?

Liquid fertilizer is not automatically better for quick results, and granular fertilizer is not always a slow- release product. Either form may contain fast- release or controlled- release nutrients depending on how it is formulated.

The physical form mainly affects how the product is mixed, distributed, watered, and absorbed. What matters most is whether the fertilizer supplies the right nutrients at the correct rate and time for the grass.

Before choosing a fertilizer, consider:

Whether the lawn is Bermuda, Zoysia, or Fescue
Whether the grass is actively growing
Current soil fertility and pH
Nutrient deficiencies identified by a soil test
Weather and soil moisture
Recent seeding or sod installation
Application equipment and calibration
The percentage of quick- and slow- release nitrogen

Applying the wrong product, or the right product at the wrong time, can waste nutrients, injure turf, or increase disease pressure.

Uniform Spray Applications

What Is Liquid Lawn Fertilizer?

Liquid fertilizer is dissolved or suspended in water and applied with spray equipment. Nutrients may be absorbed through the grass blades, soil, or both, depending on the product and application method.

Potential advantages

Can be distributed evenly with calibrated equipment
Allows accurate application across measured areas
May provide nutrients in a readily available form
Can be combined with compatible lawn treatments
Works well for targeted professional applications
Leaves no visible granules on the lawn

Points to consider

Coverage depends on sprayer calibration and technique
Some formulations require watering after application
Fast-release nutrients can increase burn risk if misapplied
Wind may affect spray placement
Product concentration and application rate must be measured carefully

Liquid fertilizer is useful when the formulation, timing, and application method match the lawn’s needs. It should not be selected simply because it is expected to produce instant color.

Measured Nutrients in Solid Form

What Is Granular Lawn Fertilizer?

Granular fertilizer consists of dry particles distributed across the lawn with a broadcast or drop spreader. The granules dissolve after irrigation or rainfall and release nutrients into the soil.

Potential advantages

Easy to see during application
Can contain controlled- or slow-release nutrients
May provide nutrients over an extended period
Can be effective across large lawn areas
Requires less mixing than many liquid products
May reduce the need for frequent applications when properly formulated

Points to consider

Uneven spreading can create stripes or missed areas
Overlapping passes can apply too much product
Granules may need to be watered into the soil
Products should be removed from pavement to prevent runoff or staining
A calibrated spreader is needed for accurate coverage

Not every granular fertilizer is slow-release. The fertilizer label identifies the nutrient sources and how much nitrogen is immediately available or released over time.

Liquid and Granular Fertilizer at a Glance

Factor	Liquid fertilizer	Granular fertilizer
Application	Applied with calibrated spray equipment	Applied with a calibrated spreader
Coverage	Even when mixed and sprayed correctly	Even when passes are properly spaced
Nutrient release	Can be quick- or controlled-release	Can be quick- or slow-release
Watering	Depends on the product label	Often watered in to dissolve granules
Convenience	Requires accurate mixing and spraying	Requires correct spreader settings
Frequency	Depends on formulation and lawn needs	Depends on formulation and release rate
Cost	Varies by product, rate, and equipment	Varies by product, coverage, and frequency
Main risks	Drift, incorrect mixing, and overlap	Spills, overlap, and uneven spreading
Best choice	Based on the lawn, season, and treatment goal	Based on the lawn, season, and treatment goal

Neither option is automatically faster, cheaper, or better for lawn health. The right choice depends on the fertilizer formulation, grass type, soil conditions, season, and application plan.

Fertilize During Active Growth

When Should Georgia Lawns Be Fertilized?

Fertilizer timing should follow the grass’s growth cycle.

Bermuda and Zoysia

These warm-season grasses grow actively from late spring through summer. Fertilization should generally begin after the lawn has greened up and entered active growth, not while the turf is still dormant.

Late or excessive nitrogen can interfere with winter preparation and increase the risk of certain lawn diseases.

Tall Fescue

Fescue is a cool-season grass that grows most actively from fall through spring. Its primary fertilization period differs from Bermuda and Zoysia. Heavy nitrogen applications during Metro Atlanta’s summer heat can place additional stress on Fescue and contribute to disease pressure.

The calendar alone should not determine an application. Weather, soil temperature, turf condition, and the current lawn program also matter.

Know What You Are Applying

What Do the Fertilizer Numbers Mean?

Fertilizer labels display three numbers representing the percentage by weight of:

Nitrogen (N): Supports blade growth and green color.
Phosphate (P₂O₅): Supports root development and other plant functions.
Potash (K₂O): Supports stress tolerance and overall plant function.

A 16-4-8 fertilizer contains 16% nitrogen, 4% phosphate, and 8% potash by weight.

The label also provides:

Recommended application rate
Lawn area covered
Watering instructions
Nutrient sources
Percentage of slow-release nitrogen
Suitable grass or plant types
Safety and storage directions

More fertilizer does not produce proportionally better results. Exceeding the labeled rate can burn turf, increase disease pressure, and allow nutrients to move away from the target area.

Fertilize With Better Information

Does Your Lawn Need More Nutrients?

Color alone does not reveal what a lawn needs. Yellowing or thin turf may result from compacted soil, poor irrigation, shade, disease, insects, incorrect mowing, or unsuitable pH.

A soil test can provide information about:

Soil pH
Phosphorus and potassium levels
Lime requirements
Nutrient imbalances
Recommended amendments

Soil tests do not typically provide a permanent nitrogen reading because nitrogen levels change quickly. Nitrogen recommendations are usually based on the grass type, season, and management program.

Apply lime only when soil- test results indicate it is needed. Lime is not fertilizer and will not correct every lawn problem.

Protect the Lawn and Landscape

What Should You Avoid?

Fertilizing dormant warm- season grass
Applying excessive nitrogen to summer- stressed Fescue
Treating drought- stressed or severely damaged turf
Assuming every yellow lawn needs fertilizer
Using an uncalibrated sprayer or spreader
Leaving fertilizer on sidewalks or driveways
Applying before heavy rain
Ignoring irrigation and drainage problems
Using a product unsuitable for the grass type
Combining fertilizer and weed control when the timing does not suit both
Applying lime without a soil test
Disregarding the product label

If fertilizer lands on a hard surface, sweep or blow it back onto the lawn. Do not wash it into a street or storm drain.

Programs for Different Property Needs

Professional Fertilization From Simply Green

Simply Green uses liquid and granular fertilizer as appropriate for the grass, season, and program. Fertilization is paired with weed control and property-specific observations rather than treated as an isolated application.
