Why Your Lawn Still Has Weeds After Fertilization (And What To Do)
Fertilizing your lawn but still seeing weeds? Learn why this happens, explore weed control methods, and implement our 6-step program for a healthier lawn.
Why Your Lawn Still Has Weeds After Fertilization (And What To Do)
If you recently fertilized your lawn but still see weeds, you are not alone. This is a common concern for homeowners, and it’s completely normal in the early stages.
Understanding Weed Control
There are two main types of weed control used in professional lawn care:
Pre-emergent prevents new weeds from growing by stopping seeds from germinating. However, it does not kill weeds that are already visible. Post-emergent treatments target and eliminate weeds that are currently growing in your lawn.
Why You’re Still Seeing Weeds
1. Weeds were already present before your first treatment, so pre-emergent won’t affect them.
2. It’s early in the program. The first round focuses on prevention, while later rounds target active weeds.
3. Weather and timing can impact effectiveness, especially with temperature changes or heavy rain.
4. Thin or weak grass allows weeds to fill in open spaces more easily.
Our Proven 6-Step Lawn Program
Round 1: Pre-emergent and fertilizer to prevent new weeds
Round 2: Fertilizer and weed control to eliminate visible weeds
Round 3: Slow-release fertilizer and grub prevention
Round 4: Summer lawn support and continued weed control
Round 5: Fall recovery fertilizer to rebuild strength
Round 6: Winterizer fertilizer for root development
What To Expect After
Round 1: You may still see weeds, which is normal.
After Rounds 2–3: Expect significant weed reduction.
By Fall: You should see a thicker, healthier, and more uniform lawn.
How to Maximize Results
• Mow consistently and avoid cutting too short
• Water deeply but not too often
• Aerate and overseed in the fall
• Stick to your treatment plan
Final Thoughts
Seeing weeds after your first treatment doesn’t mean the program isn’t working. It just means you are early in the process. A healthy, weed-free lawn takes time, consistency, and proper care.
