How to Prevent Weeds in Your New Sod Lawn
Weeds can be a nuisance in any lawn, but preventing them in newly installed sod is essential for maintaining a lush, green yard. At Long Island Sod Company, we help homeowners protect their sod from weeds with proper lawn care techniques. Follow this guide to keep your sod weed-free.
Why Do Weeds Appear in New Sod?
- Soil Disturbance – When preparing soil for sod, dormant weed seeds may be exposed to sunlight, triggering growth.
- Improper Watering – Overwatering or underwatering can weaken sod, allowing weeds to take over.
- Lack of Fertilization – Poor soil nutrition makes sod less competitive against invasive weeds.
Tips to Prevent Weeds in New Sod
- Start with Healthy, High-Quality Sod
✅ Choose farm-fresh sod that is free from weeds and pests.
✅ Install sod promptly to prevent weeds from taking hold.
- Prepare the Soil Properly
✅ Remove all weeds before laying sod.
✅ Apply a starter fertilizer to promote strong root growth.
✅ Level the soil to eliminate dips where weeds may take root.
- Water Correctly
✅ Water 2-3 times per day for the first two weeks to establish deep roots.
✅ Avoid overwatering, as excess moisture creates ideal conditions for weed growth.
✅ Once established, transition to deep watering 2-3 times per week to strengthen roots.
- Mow at the Right Height
✅ Allow sod to root before the first mow (2-3 weeks after installation).
✅ Mow at the recommended height for your sod type:
- Kentucky Bluegrass: 2.5-3 inches
- Tall Fescue: 3-4 inches
- Zoysia Grass: 1.5-2.5 inches
✅ Taller grass shades the soil, making it harder for weeds to sprout.
- Avoid Herbicides Too Soon
🚫 Do not use weed killers within the first 6 weeks of sod installation.
✅ After 6 weeks, use a pre-emergent herbicide to prevent weeds from germinating.
✅ Hand-pull any weeds that appear instead of using chemicals too soon.
Keep Your Lawn Weed-Free Year-Round
- Spring & Fall: Apply a balanced fertilizer to strengthen sod and outcompete weeds.
- Summer: Water deeply and mow high to prevent heat stress and weed invasion.
- Winter: Remove fallen leaves to prevent mold and hidden weed seeds.
