Keeping Your Jacksonville Lawn Thriving in Summer Heat
Jacksonville lawns are battling extreme summer heat and dry conditions. Learn how proper mowing, irrigation, and watering can help protect your lawn.
Jacksonville Lawn Care During Extreme Heat & Drought: What Homeowners Should Know
If your lawn around Jacksonville looks more stressed than usual this August, you’re not imagining it.
Northeast Florida has been dealing with prolonged dry conditions, water restrictions, and some seriously hot summer temperatures. Even the warm-season grasses we commonly see around Jacksonville can start showing signs of stress when high temperatures and limited rainfall continue week after week.
For Jacksonville homeowners, the goal right now isn’t necessarily to force the lawn to look perfect. It’s to help the grass make it through the heat without creating additional stress.
Why Jacksonville Lawns Are Struggling Right Now
Jacksonville lawns normally get plenty of help from our summer afternoon thunderstorms. When those storms become less consistent, lawns depend much more heavily on irrigation.
At the same time, Northeast Florida remains under water-use restrictions because of prolonged dry conditions and declining regional water levels.
That creates a difficult combination: your lawn needs moisture at exactly the time you’re being asked to conserve it.
The solution isn’t simply running the sprinklers longer. Proper mowing, efficient irrigation, and identifying problem areas become much more important.
Don’t Cut Your Grass Too Short
One of the easiest ways to make heat stress worse is cutting a lawn too low.
Grass with adequate leaf growth provides more shade to the soil and root zone. Scalping or aggressively lowering the mowing height during extremely hot, dry weather can expose the lawn to additional stress.
This is particularly important with St. Augustine grass, which is common throughout Jacksonville.
A lawn that’s already struggling doesn’t need another setback from an unnecessarily aggressive cut.
Make the Water You Can Use Count
During dry weather, irrigation coverage matters just as much as irrigation time.
A sprinkler system can run for an hour and still leave portions of a yard dry if you have:
Broken or clogged sprinkler heads
Heads that have sunk below the turf
Incorrect nozzles
Poor spray patterns
Zones with uneven coverage
Leaking irrigation lines
Look for unusually dry sections of the lawn while everything around them remains green. A defined brown or stressed area can sometimes indicate an irrigation coverage problem rather than simply a lack of water throughout the entire property.
Running each irrigation zone individually can help identify these problems.
Follow Current Jacksonville Watering Restrictions
Jacksonville and much of Northeast Florida remain under water-use restrictions, so don’t assume your normal irrigation schedule still applies.
The St. Johns River Water Management District periodically adjusts watering requirements based on drought and water-supply conditions.
Before changing your irrigation controller, check the current restrictions for your property and address.
And remember: more water isn’t automatically better.
Overwatering can create its own problems, including shallow root development, fungus and unnecessary runoff.
The goal should be getting the correct amount of water to the correct areas as efficiently as possible.
Watch Newly Installed Sod Closely
New sod deserves additional attention during periods of extreme heat.
Unlike an established lawn, freshly installed sod hasn’t developed a mature root system into the existing soil. That makes moisture management particularly important during establishment.
If you’re considering sod installation in Jacksonville during the hottest part of summer, irrigation coverage should be checked before installation whenever possible.
Installing new sod over an irrigation system with broken heads or poor coverage can quickly create problems.
This is one reason we frequently evaluate irrigation while planning sod projects.
Brown Grass Doesn’t Always Mean Dead Grass
A brown area isn’t automatically a dead lawn.
Heat stress, drought stress, poor irrigation coverage, insects, disease, compacted soil, shade and other conditions can create similar-looking symptoms.
Before replacing an entire section of turf, determine what’s actually causing the problem.
If the issue is irrigation coverage, installing new sod without correcting the irrigation problem can simply recreate the same dead area.
Keep an Eye on Your Irrigation System
August is a good time to actually watch your sprinkler system operate instead of assuming everything is working correctly.
Turn the system on manually and walk the property.
Look for heads spraying sidewalks, driveways or buildings. Check for unusually low pressure, water bubbling from underground, clogged nozzles and areas that aren’t receiving coverage.
Small irrigation problems become much more noticeable when Jacksonville goes through stretches of hot, dry weather.
Jacksonville Lawn Care Is About Adjusting to the Conditions
There isn’t one lawn-care schedule that works perfectly every week of the year in Northeast Florida.
Our weather changes.
Rainfall changes.
Grass growth changes.
And your lawn care should adjust with it.
During extremely hot and dry periods, protecting the health of the turf is more important than trying to force rapid growth.
