Fall Fertilization in Lafayette, Youngsville & Broussard: A Homeowner’s Guide
Fall fertilization is one of the most misunderstood parts of landscape maintenance in South Louisiana. When done correctly, it improves root health, reduces stress, and prepares lawns, trees, and shrubs for winter and spring growth.
Is September the Right Time to Fertilize in Louisiana?
Yes — if you fertilize lightly and correctly.
In Lafayette, Youngsville, and Broussard, September temperatures remain warm, but plants are shifting energy toward root development. Using a slow-release fertilizer helps strengthen roots without encouraging excessive top growth.
What Plants Benefit from Fall Fertilization?
- Lawns - Supports deeper roots and improves overall turf health heading into fall.
- Trees & Shrubs- Helps established plants prepare for cooler weather and improves spring performance.
- Perennials- Encourages nutrient storage in root systems for next season.
What Should Not Be Fertilized in Fall?
Avoid fertilizing:
-
Dormant plants
-
Declining annual flowers
-
Heat-stressed or unhealthy plants
Incorrect fertilization timing can increase fungus and insect problems in South Louisiana landscapes.
Why Fall Irrigation Adjustments Matter
Overwatering is one of the most common fall landscape mistakes. Cooler temperatures mean less evaporation, and excess water can lead to shallow roots and disease.
Best Fall Irrigation Practices:
-
Water lawns once or twice per week
-
Reduce run times by 20–30%
-
Water shrubs deeply but less often
Always monitor soil moisture instead of relying solely on timers.

Professional monitoring and early treatment can prevent long-term issues.
