Choosing the right fertilizer is key to transforming your Fresno lawn from struggling to lush. In our unique Central Valley climate, your turf needs specific nutrients to thrive. Here's a concise guide to help you select and apply the best fertilizers throughout the year.

Fertilizer Basics

Fertilizers supply three main nutrients, known as the NPK ratio:

• Nitrogen (N): Boosts leaf growth and enhances green color.
• Phosphorus (P): Promotes strong root development.
• Potassium (K): Improves disease resistance and drought tolerance.

Two common types of fertilizers:

Granular:

• Slow-release formulas ideal for hot climates.
• Even nutrient distribution with less frequent application.
• Lower risk of burning.

Liquid:

• Fast-acting for quick nutrient fixes.
• Even coverage but requires more frequent use.

Seasonal Fertilizer Recommendations

• Spring (March–May): Use a 20-5-10 blend. High nitrogen supports vigorous early growth; moderate phosphorus develops roots, and potassium helps resist summer stress.
• Summer (June–August): Opt for a 15-5-15 mix. A balanced formula with extra potassium combats heat stress; slow-release types help avoid burning.
• Fall (September–November): Choose a 13-25-12 ratio. Increased phosphorus strengthens roots for winter, while moderate nitrogen and extra potassium maintain color and winter hardiness.

Application Tips

Timing:

• Apply early morning or late evening to avoid peak heat.
• Water thoroughly after application.
• Space treatments 6–8 weeks apart.

Coverage:

• For standard lawns: about 1 pound of nitrogen per 1,000 square feet.
• For new seedings: roughly ½ pound per 1,000 square feet.
• Adjust based on soil test results.

Common Mistakes to Avoid

• Over-Application: Can burn your grass and harm the environment.
• Poor Timing: Avoid fertilizing during peak heat or on dormant grass.
• Uneven Distribution: Leads to patchy growth and wasted product.

Professional Fertilization

While DIY fertilization can work, professional services offer:

• Precise measurement and custom-blended fertilizers.
• Use of professional-grade products and consistent scheduling.
• Soil testing and ongoing monitoring for optimal nutrient balance.

Signs Your Lawn Needs Fertilizer

Look for these indicators:

• Yellowing or slow-growing grass.
• Thin or patchy areas.
• Increased weed growth signaling weakened turf.

Environmental Considerations

• Eco-Friendly Options: Consider organic or compost-based fertilizers and natural soil amendments.
• Water Conservation: Healthy roots require less water and make better use of available moisture, reducing overall irrigation needs.

Getting Started

To achieve the best results:

• Test Your Soil: Identify nutrient deficiencies.
• Select Seasonal Fertilizers: Choose products that match your lawn’s needs.
• Follow Application Guidelines: Apply at the right time and rate.
• Monitor and Adjust: Keep track of your lawn’s response and tweak your plan as needed.
