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
- Cooler temperatures mean less evaporation
- Grass blades dry before nightfall, reducing disease risk
- Lower wind speeds improve water distribution
- Typically lower water pressure demand in LaPlace
Late Evening (After 4 PM) ⚠️ OKAY
- Better than midday, but grass may stay wet overnight
- Can increase fungal disease in humid Louisiana climate
- Only use if morning watering isn't possible
Midday (10 AM - 4 PM) ❌ AVOID
- Up to 50% water loss from evaporation
- Wastes water and money
- Can scald grass blades in extreme heat
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
- Footprint test: Grass blades don't spring back after walking on them
- Color change: Grass turns blue-gray or dull green
- Blade folding: Grass blades fold or curl inward
- Dry soil: Top 6 inches of soil feels dry to the touch
⚠️ 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
Water Conservation Tips
- Install a rain sensor to automatically shut off sprinklers
- Use soaker hoses or drip irrigation for flower beds
- Raise mower height to 3-4 inches (taller grass retains moisture)
- Mulch around trees and plants to reduce evaporation
- Fix sprinkler leaks promptly
- Check LaPlace water restrictions during drought periods
Sprinkler System Recommendations
For LaPlace homeowners with irrigation systems:
- Run time: 30-45 minutes per zone
- Pressure: 30-50 PSI for optimal coverage
- Head spacing: Ensure overlapping coverage (no dry spots)
- Maintenance: Check and clean heads monthly
