Louisiana Lawn Watering Guide

November 2025

Proper watering is essential for maintaining a healthy, green lawn in LaPlace and the River Parishes. With Louisiana's hot, humid summers and frequent rainfall, finding the right watering balance can be tricky. This guide will help you develop an effective watering strategy for your lawn.

The Golden Rule: Deep and Infrequent

The most important principle of lawn watering is deep watering 1-2 times per week rather than daily light watering. Deep watering encourages grass roots to grow deeper into the soil, creating a more drought-resistant lawn that can better handle Louisiana's variable weather.

💧 Pro Tip: The 1-Inch Rule

Your lawn needs about 1 to 1.5 inches of water per week (including rainfall). Place empty tuna cans around your lawn while watering to measure how much water your sprinklers deliver. When the can has 1 inch of water, you're done!

Best Time to Water

In the River Parishes, timing is crucial for effective watering:

Early Morning (4 AM - 10 AM) ✅ BEST

Late Evening (After 4 PM) ⚠️ OKAY

Midday (10 AM - 4 PM) ❌ AVOID

Seasonal Watering Schedule for LaPlace

🌸 Spring (March - May)

Frequency: 1-2 times per week
Amount: 1 inch total (including rain)
Spring brings frequent rain showers to LaPlace. Monitor rainfall and adjust accordingly. St. Augustine grass begins actively growing in late March.

☀️ Summer (June - August)

Frequency: 2-3 times per week
Amount: 1-1.5 inches total
Peak growing season with high heat and humidity. Watch for afternoon thunderstorms which can provide significant water. Increase frequency during dry spells.

🍂 Fall (September - November)

Frequency: 1 time per week
Amount: 0.75-1 inch
Cooler temperatures and occasional rain reduce water needs. Grass growth slows but remains active until first frost.

❄️ Winter (December - February)

Frequency: Every 2-3 weeks (if needed)
Amount: 0.5 inch
Warm-season grasses go dormant. Only water if ground is dry and no rain for 2+ weeks. Overwatering can promote disease.

Signs Your Lawn Needs Water

⚠️ Common Watering Mistakes in Louisiana

  • Watering too frequently: Shallow roots make grass vulnerable
  • Watering at night: Promotes fungus and disease in humid climate
  • Ignoring rainfall: Turn off sprinklers when it rains!
  • Uneven coverage: Some areas get too much, others too little
  • Running sprinklers too short: Water doesn't penetrate deep enough
