How To Apply Liquid Lawn Fertilizers?
Applying liquid lawn fertilizers correctly is essential to ensure optimal results and prevent damage to your grass. Follow these steps for a successful application:
- Choose the right fertilizer: Select a liquid lawn fertilizer that meets your lawn’s specific nutrient requirements. Read the product label carefully to understand the correct application rates and guidelines.
- Prepare the equipment: Liquid lawn fertilizers can be applied using various methods, such as hose-end sprayers, backpack sprayers, or irrigation systems. Choose a suitable method and ensure that your equipment is clean and functioning correctly.
- Measure and mix: Accurately measure the required amount of liquid fertilizer based on the product’s recommendations and your lawn size. If necessary, dilute the concentrate with water according to the manufacturer’s instructions.
- Test the application: Before applying the fertilizer to your entire lawn, test the equipment on a small, inconspicuous area to ensure even coverage and avoid over-application.
- Apply evenly: Start at one corner of your lawn and work your way across, applying the liquid fertilizer in a consistent, overlapping pattern. Make sure to maintain a steady walking speed and consistent pressure on the sprayer to ensure even distribution.
- Water lightly (if needed): Some liquid fertilizers may require watering after application to help the nutrients penetrate the soil. Follow the product’s guidelines for post-application watering.
- Clean up: Thoroughly rinse your equipment after use to prevent buildup and ensure proper function for future applications.
- Monitor results: Keep an eye on your lawn’s health after applying the liquid fertilizer. If you notice any signs of over-fertilization, such as yellowing or wilting, adjust your application rate or frequency accordingly.
Following these steps can let you apply liquid lawn fertilizers effectively and safely, promoting a healthy, vibrant lawn. If you want to know even more about liquid fertilizers, check out my article “Liquid fertilizer 101”.
Understanding Granular Fertilizers
Granular fertilizers are solid pellets made from a mixture of nutrients. They can be applied using a broadcast spreader, drop spreader, or by hand. Here are some factors to keep in mind:
- Slow-release: Granular fertilizers release nutrients over time, providing a steady supply to your lawn.
- Long-lasting: They generally last longer than liquid fertilizers, reducing the need for frequent applications.
- Low runoff risk: Granular fertilizers are less likely to contribute to nutrient runoff, reducing environmental impact.
| Pros | Cons |
|---|---|
| Slow-release of nutrients | Slower absorption |
| Long-lasting effect | Less precise application |
| Lower risk of nutrient runoff | Limited customization of nutrient blend |
| Less frequent application | Potential for over-application |
| Easy to store and handle | May require proper spreader equipment |
How To Apply Granular Fertilizers?
Proper application of granular fertilizers is crucial for achieving the best results and preventing damage to your lawn. Follow these steps for a successful application:
- Choose the right fertilizer: Select a granular lawn fertilizer that meets your lawn’s specific nutrient needs. Carefully read the product label to understand the appropriate application rates and guidelines.
- Prepare the equipment: Granular fertilizers can be applied using a broadcast spreader, drop spreader, or by hand. Choose the most suitable method for your lawn and ensure that your equipment is clean and functioning correctly.
- Calibrate the spreader: To achieve even coverage, calibrate your spreader according to the manufacturer’s instructions and the recommended application rate for the fertilizer product.
- Fill the spreader: Pour the measured amount of granular fertilizer into the spreader’s hopper, taking care not to overfill it.
- Test the application: Before applying the fertilizer to your entire lawn, test the spreader on a small, inconspicuous area to ensure even coverage and avoid over-application.
- Apply evenly: Begin at one corner of your lawn and work your way across, applying the granular fertilizer in a consistent, overlapping pattern. Maintain a steady walking speed and adjust the spreader settings as needed to ensure even distribution.
- Water the lawn (if needed): Some granular fertilizers may require watering after application to help the nutrients penetrate the soil and reduce the risk of burning the grass. Follow the product’s guidelines for post-application watering. I’ve covered when to water your lawn after fertilizing in this article here as well.
- Clean up: Empty any remaining fertilizer from the spreader and thoroughly rinse your equipment after use to prevent buildup and ensure proper function for future applications.
- Monitor results: Keep an eye on your lawn’s health after applying the granular fertilizer. If you notice any signs of over-fertilization, such as yellowing or wilting, adjust your application rate or frequency accordingly.

Choosing the Right Fertilizer for Your Lawn
If you have access to both types of fertilizers and if you’re a beginner, it can be hard to make a quick decision. I have also experienced this situation when I was a beginner.
When deciding between liquid and granular fertilizers, consider the following factors:
- Lawn condition: If your lawn needs a quick boost, liquid fertilizer may be the better option. For long-term maintenance, granular fertilizers can be more effective.
- Soil type: Some soils have difficulty holding onto nutrients, making liquid fertilizers a better choice. In other cases, granular fertilizers may be more appropriate.
- Application frequency: If you prefer a low-maintenance approach, consider granular fertilizers. However, if you’re willing to apply fertilizer more frequently, liquid options might be preferable.
Tip:In some situations, using both liquid and granular fertilizers can provide the best results. For example, applying a liquid fertilizer in the spring for a quick green-up, followed by a slow-release granular fertilizer to maintain steady growth throughout the season.
