Preventing Weeds in Your New Jersey Sod Lawn

Weeds can quickly take over a lawn if not managed properly, especially in newly installed sod. At New Jersey Sod Company, we help homeowners maintain a lush, weed-free lawn with expert sod care. Follow this guide to keep your sod in top condition.

Why Do Weeds Appear in New Sod?

  • Soil Disturbance – Tilling and preparing soil can bring dormant weed seeds to the surface.
  • Improper Watering – Overwatering or underwatering weakens sod, allowing weeds to take hold.
  • Lack of Fertilization – Poor soil nutrition makes sod less competitive against weeds.

Tips to Prevent Weeds in New Sod

1. Start with High-Quality Sod

✅ Choose fresh, farm-grown sod free of weeds.
✅ Install sod immediately after delivery to prevent weed seed contamination.

2. Prepare the Soil Properly

✅ Remove all weeds before laying sod.
✅ Apply a starter fertilizer to promote deep root growth.
✅ Level the soil to eliminate gaps where weeds may grow.

3. Water the Right Way

✅ Water 2-3 times per day for the first two weeks to establish deep roots.
✅ Avoid overwatering, which encourages weeds and fungus growth.
✅ Once established, transition to deep watering 2-3 times per week to promote a strong root system.

4. Mow at the Correct Height

✅ Allow sod to root before the first mow (2-3 weeks after installation).
✅ Follow these recommended mowing heights:

  • Kentucky Bluegrass: 2.5-3 inches
  • Tall Fescue: 3-4 inches
  • Zoysia Grass: 1.5-2.5 inches

✅ Taller grass shades the soil, preventing weed growth.

5. Avoid Herbicides Too Soon

🚫 Do not use weed killers within the first 6 weeks of sod installation.
✅ After 6 weeks, apply a pre-emergent herbicide to prevent weeds from sprouting.
✅ Hand-pull any weeds that appear instead of using chemicals too soon.

Year-Round Lawn Care to Prevent Weeds

  • Spring & Fall: Apply a balanced fertilizer to strengthen sod and prevent weed growth.
  • Summer: Water deeply and mow high to prevent heat stress and weed invasion.
  • Winter: Remove fallen leaves to prevent mold and hidden weed seeds.
