Seasonal Lawn Care Calendar for South Louisiana: What to Do Each Month

2/18/2025

2 Comments

 
Keeping a lush, green lawn in South Louisiana is a year-round commitment. With high humidity, heavy rainfall, scorching summers, and occasional cold snaps, maintaining a healthy lawn in Baton Rouge and New Orleans requires a strategic approach.

To help homeowners manage their lawn throughout the year, we’ve created a month-by-month lawn care calendar that ensures your yard stays green, weed-free, and resilient in Louisiana’s unique climate.
​
Whether you’re battling summer droughts, fall pests, or springtime weeds, this guide will keep your lawn looking its best every season!

​Understanding Louisiana’s Lawn Care Challenges
Before diving into the seasonal schedule, it’s important to understand the key challenges South Louisiana homeowners face:
​
🌧️ High Humidity & Rainfall – Creates the perfect conditions for fungal diseases, weeds, and poor drainage.
🔥 Extreme Heat in Summer – Can stress the lawn, causing brown patches and pest infestations.
❄️ Occasional Cold Snaps in Winter – Although rare, cold temperatures can damage warm-season grasses.
🌱 Year-Round Weed Growth – The mild climate allows weeds to thrive, requiring constant prevention.
​
Now, let’s break down what you should be doing each season to keep your lawn healthy and beautiful!
​Month-by-Month Lawn Care Guide

Winter (December - February): Preparing for Spring
Although your lawn grows slowly during winter, proper preparation will set the stage for a strong comeback in spring.
​
✅ Lawn Care Tasks:
  • Minimal mowing – Only mow if necessary, and keep grass at 2.5 to 3 inches.
  • Lawn cleanup – Remove leaves, sticks, and debris to prevent mold and fungus growth.
  • Apply pre-emergent herbicide – Prevent spring weeds like crabgrass and clover before they emerge.
  • Fertilization (if needed) – Apply a winterizing fertilizer to strengthen roots.
  • Monitor for fungal diseases – With damp conditions, brown patch can develop, especially in St. Augustine grass.
​
💡 Pro Tip: If you have warm-season grass (like Bermuda or Centipede), avoid over-fertilizing in winter, as it can lead to fungal problems.
​Spring (March - May): Growth & Weed Prevention
Spring is one of the most crucial seasons for lawn care. This is when grass starts growing again, and weeds try to take over.

​✅ Lawn Care Tasks:
  • Begin regular mowing – Keep grass at 3-4 inches to shade out weeds.
  • Apply pre-emergent herbicides – Prevent broadleaf weeds and crabgrass from sprouting.
  • Fertilization – Apply a balanced fertilizer to promote healthy green growth.
  • Aeration (if needed) – Helps break up compacted soil and improves water absorption.
  • Check irrigation system – Ensure sprinklers are working properly before summer heat arrives.
​
💡 Pro Tip: If you spot dandelions or clover, apply a post-emergent herbicide early before they spread!
​Summer (June - August): Heat & Drought Management
Louisiana summers can be brutally hot and humid, putting stress on your lawn. Watering, mowing, and pest control become top priorities.
​
✅ Lawn Care Tasks:
  • Raise mowing height – Keep grass at 4 inches or higher to protect the soil from extreme heat.
  • Deep watering – Water 1-1.5 inches per week, preferably early in the morning.
  • Slow-release fertilizer – Helps maintain color and health without burning the grass.
  • Watch for pests – Chinch bugs, armyworms, and grubs can cause brown patches.
  • Manage fungal diseases – With high humidity, keep an eye out for brown patch and dollar spot fungus.
💡 Pro Tip: If your lawn develops yellow or brown spots, check for pest infestations or drainage issues before applying more fertilizer.
Fall (September - November): Recovery & Prep for Dormancy
As temperatures cool down, fall is the best time for lawn recovery and preparation before winter.
​
✅ Lawn Care Tasks:
  • Aeration – Loosen compacted soil and increase root growth.
  • Overseeding (if needed) – Apply cool-season grass seed (like Ryegrass) if you want green grass in winter.
  • Final fertilization – Apply a fall fertilizer with potassium to strengthen roots.
  • Leaf removal – Leaves left on the lawn trap moisture and lead to disease.
  • Apply pre-emergent herbicide – Stop winter weeds like chickweed and henbit before they spread.
💡 Pro Tip: If you plan to dethatch your lawn, fall is the best time before winter dormancy kicks in!

​

Best Grass Types for South Louisiana
The best grass types for Baton Rouge and New Orleans are:
✅ St. Augustine – Best for shade but requires fungus prevention.
✅ Bermuda – Great for high-traffic areas and full sun.
✅ Centipede – Low-maintenance and thrives in acidic Louisiana soil.
✅ Zoysia – Thick, drought-tolerant, and great for weed prevention.

Common Lawn Diseases & Pests in Louisiana
👀 Look out for:
  • Brown Patch Fungus – Common in humid conditions (Spring & Fall)
  • Chinch Bugs – Cause dry, brown patches in Summer
  • Armyworms – Can wipe out entire lawns in weeks (Summer & Fall)
  • Grubs – Damage grass roots in late Summer
If you notice these issues, professional lawn treatment may be necessary.
Keeping a healthy lawn in Louisiana requires consistent care throughout the year. By following this seasonal lawn care calendar, you’ll be able to:
✅ Prevent weeds & lawn diseases
✅ Keep grass lush, green, and pest-free
✅ Prepare your yard for extreme weather conditions

This is a thorough and practical guide—while our climate here in Saskatchewan is certainly different from Louisiana’s, the structured, month-by-month approach is still really helpful. Lawn care in the Prairies comes with its own set of seasonal challenges (hello, long winters and dry spells), but the emphasis on timing, weed prevention, and soil health translates well across regions. Always great to see region-specific advice like this—it inspires us to adapt and apply best practices to our own unique growing conditions up north. Thanks for sharing!
