Mowing your lawn means cutting the grass to a consistent, healthy height using a lawn mower. It is one of the most basic parts of Louisiana lawn care because it keeps grass looking neat, encourages thicker growth, and helps prevent weeds from taking over.
In South Louisiana, grass grows quickly because of the heat and humidity. That makes regular lawn maintenance especially important for keeping your yard healthy and attractive throughout the year.
Why Lawns Grow So Fast in South Louisiana
Tangipahoa Parish sits in USDA hardiness zones 8b to 9a, which creates the perfect conditions for fast, near-constant grass growth:
- Long, hot, humid summers and mild winters that barely slow grass down
- More than 60 inches of rain a year, feeding growth almost year-round
- St. Augustine grass, common across Ponchatoula, Hammond, Amite, and surrounding areas, thrives in this heat and humidity
- A growing season that stretches nearly the entire calendar instead of just a few months
The result is grass that grows faster here than in many other parts of the country. That is why following a local grass-cutting schedule is so important.
The Seasonal Mowing Schedule
Instead of sticking to one fixed number all year, adjust your lawn mowing schedule based on how fast your grass is actually growing.
1. Spring (March–April)
Growth accelerates once soil temperatures reach around 65°F. Start with how often to mow lawn visits around every 10 days, then shift to weekly as the weather warms.
2. Summer (May–September)
This is peak growing season in Louisiana. Mow every 5 to 7 days without exception. During the hottest and wettest stretches of July and August, some lawns may even need a cut every 5 days.
3. Fall (October–November)
As temperatures drop, grass growth starts to slow. Stretch your grass cutting schedule to every 10 to 14 days, and watch the grass rather than the calendar.
4. Winter (December–February)
St. Augustine rarely goes fully dormant in South Louisiana, but growth is minimal. Mow only as needed, usually every three to four weeks during warm spells. During cold snaps, you may not need to mow at all.
Don’t Cut More Than One-Third
A simple rule can make a big difference in your lawn’s health: never cut more than one-third of the grass height at one time. For example, if your grass is 6 inches tall, only cut about 2 inches. This leaves the grass at 4 inches and helps it stay healthy.
If your lawn has grown too tall, don’t cut it down to your normal height all at once. Cutting too much can stress the grass and leave it more exposed to Louisiana’s strong sun, heat, and weeds.
Instead, lower the grass gradually
- Cut no more than one-third of the grass height.
- Wait two to three days.
- Mow again until you reach your desired height.
It may take a little longer, but this simple approach helps keep your lawn strong, healthy, and better able to handle Louisiana’s weather.
The Right Mowing Height for Your Grass
Cutting at the correct height matters just as much as cutting on the right schedule. St. Augustine grass, the most common type in the area, does best at 3.5 to 4 inches. This is taller than many mower manufacturers set as the default, so it’s worth double-checking your deck height with a ruler. Taller grass shades the soil, holds in moisture, and crowds out weeds.
Centipede grass prefers a shorter cut, around 1.5 to 2 inches. Zoysia, if you have it, does well between 1.5 and 2.5 inches.
When to Mow (and When Not To)
Choosing the best time to mow the lawn can make the job easier and help your grass stay healthy. Louisiana’s heat, humidity, and frequent rain can all affect when you should cut.
1. Mow in the Morning or Evening
During Louisiana’s hot summer months, try to mow in the early morning or evening. These cooler parts of the day are easier on both you and your grass. Avoid mowing during the hottest part of the afternoon, when strong sunlight and high temperatures can put extra stress on the lawn.
2. Avoid Mowing Wet Grass
It is best to wait until your lawn is dry before mowing. Wet grass can stick to the mower and may tear instead of getting a clean cut. This can leave the grass with uneven, ragged edges and may increase the risk of lawn problems.
3. Make the Most of Dry Weather
Louisiana can get frequent afternoon storms, which can make mowing difficult. If rain is expected later in the day, a dry morning may be your best opportunity to mow. Even if the ground is slightly damp, wait until the grass itself is dry enough to cut cleanly.
The goal is simple: choose a cooler, dry time when your grass is ready to be mowed. This helps you get a cleaner cut while keeping your lawn in better condition.
Signs Your Lawn Needs a Different Schedule
A calendar is a helpful guide, but your lawn will tell you what it actually needs. Watch for these signs instead of mowing on a fixed date:
- Grass height exceeding your target by more than a third
- Visible seed heads or a stemmy texture, both signs it’s overdue
- Slower growth after a cool snap or dry spell, meaning you can wait a few extra days
Pay attention to these cues, and your lawn will practically schedule itself.
When Mowing Feels Like a Second Job
Keeping up with Louisiana lawn mowing during peak summer can feel like nonstop work. Between the heat, humidity, and near-weekly mowing, it is easy to fall behind. Once a lawn gets overgrown, bringing it back to a healthy, even cut can take real effort.

FAQs
1. Is mowing three times a week too much?
Yes. It doesn’t give the grass time to recover and can stress the roots, even in peak summer.
2. Is 10 minutes of watering the lawn enough?
Usually not. Louisiana lawns need about 1 to 1.5 inches of water per week, applied in fewer, longer sessions.
3. What is the 1/3 rule of mowing?
Never cut more than one-third of the grass blade’s height in a single mow. It protects the roots and keeps grass healthy.
4. Is it better to leave cut grass on the lawn or pick it up?
Short clippings can stay and break down naturally. Long or clumped clippings should be raked or bagged so they don’t smother the grass.
5. How do I know if I’m mowing my lawn too often?
Look for thin patches, exposed soil, or pale grass. These signs mean it’s time to stretch out your mowing schedule.
A Lawn That Stays on Schedule, All Year Long
A good grass cutting schedule in Louisiana is not a one-size-fits-all plan. It changes with the seasons, your grass type, and the weather each week. Following the one-third rule, choosing the right mowing height, and paying attention to how your lawn is growing can help keep it healthy through even the toughest summer stretch. Good lawn maintenance also means knowing when to mow and when to give your grass a little more time.
