How to Prevent Sod from Drying Out During Summer

Keep Your Lawn Green and Healthy All Season in Vancouver, WA

Hot summer days in the Pacific Northwest can take a toll on even the healthiest lawns — especially newly installed sod. If you’ve recently invested in a fresh, green lawn, the last thing you want is for it to dry out, brown, or die in the heat.

At L&A Landscaping Specialists, we’ve helped hundreds of homeowners in Vancouver, WA protect their lawns from summer stress. In this post, we’ll show you exactly how to prevent your sod from drying out during summer, keeping it lush, vibrant, and thriving all season long.

🌡️ Why Summer is Tough on New Sod

Summer sod stress is caused by a combination of:

• High temperatures
• Increased evaporation
• Under-watering or inconsistent watering
• Improper mowing habits
• Poor soil contact or shallow root growth

New sod is especially vulnerable because it hasn’t fully rooted yet — meaning it can’t pull moisture from deeper soil like mature grass.

💧 Step 1: Water Deep and Consistently

✅ For new sod (first 30 days):

• Days 1–10: Water 2–3x per day for 10–15 minutes per zone
• Days 11–21: Water once per day deeply for 20–30 minutes
• After 3 weeks: Water 2–3x per week, deeply and early in the morning

💡 Water between 4am and 9am to minimize evaporation and reduce disease risk.

✅ For established sod:

• Water 2–3 times per week depending on temperature
• Focus on deep watering — the soil should be moist 3–4 inches deep

🌞 Step 2: Avoid Afternoon Watering

Don’t be fooled — watering at noon or in the afternoon wastes water due to evaporation and can cause grass to scorch. Morning watering allows moisture to soak in and helps prevent fungal growth overnight.

✂️ Step 3: Mow Smart (and High)

Keep your mower set to 3–4 inches during summer. Taller grass:

• Shades the soil
• Retains moisture better
• Develops deeper roots

Also, avoid mowing during peak heat or immediately after watering.

⚠️ Never remove more than 1/3 of the grass height at once — it shocks the sod and increases water stress.

🍃 Step 4: Add Mulch Around Edges and Hot Spots

For areas near sidewalks, driveways, or sunny slopes — use mulch or shade cloth to protect the edges. Sod near hardscapes tends to dry out first because of reflected heat.

🧪 Step 5: Use Soil Conditioner or Wetting Agents (Optional)

If your soil is hard or compacted, water may not penetrate properly. In these cases, we recommend:

• Soil conditioners to improve water absorption
• Wetting agents for hydrophobic soil (soil that repels water)
• Annual aeration to open up the soil and promote deeper root growth

🔍 Step 6: Monitor Your Lawn Daily

During hot spells (especially over 85°F), check for signs of dehydration:

• Grass turning blue-gray
• Footprints that don’t bounce back
• Edges browning before the center

If you notice these signs, increase your watering duration — not frequency.

🚿 Bonus: Consider a Smart Irrigation System

Want to automate everything? Install a smart irrigation controller that adjusts watering based on real-time weather. It’s the best way to prevent over- or under-watering during unpredictable summer heatwaves.

✅ Don’t Let Summer Destroy Your Investment
