It’s been a challenging spring for homeowners across the Midlands. While we’re used to April showers helping lawns thrive heading into summer, this year has been a different story. Extended dry periods, below-average rainfall, and rising temperatures have pushed much of our area into drought conditions. As a result, many homeowners are noticing brown patches, thinning turf, and areas of grass that seem to be declining almost overnight. If that sounds familiar, you’re probably asking the same question we’re hearing throughout Lexington, Columbia, Irmo, and surrounding communities:
“Is it fungus or drought stress?”
It’s a fair question. Both problems can make a lawn look unhealthy, discolored, and even dead in certain areas. The challenge is that many homeowners mistake one for the other—and treating the wrong problem can waste time, money, and potentially make the situation worse.
Recently, our team at Sprout Tech Turf Solutions was called out to a beautiful property in Lexington, South Carolina, by our referral partner Austin with Premier Lawnscapes. The homeowner was concerned that fungus was damaging the lawn.
After walking the property, evaluating the turf, and looking at current weather conditions, we quickly realized the issue wasn’t disease at all.
The lawn was showing classic signs of drought stress.
Before you reach for fungicides or assume your lawn has a serious disease problem, watch the video below and learn what we found.
Watch: Is It Fungus or Drought Stress?
Is It Fungus or Drought Stress? Here’s What We Found in Lexington
At first glance, the homeowner’s concerns made sense.
There were visible brown areas developing in sections of the lawn while other parts remained healthy and green. Many homeowners immediately associate brown turf with fungus because lawn diseases often become a concern during warm weather.
However, there were several clues pointing us in a different direction.
The biggest factor?
Heat.
When temperatures climb into the 90s and nighttime temperatures remain elevated, turfgrass requires significantly more water than it does during spring.
Earlier in the year, we often caution homeowners against overwatering. During cooler months, excessive irrigation can encourage disease pressure, shallow root development, and wasted water.
But once summer arrives, the rules change.
A watering schedule that worked perfectly in April may leave your lawn struggling in July.
Why Drought Stress Is Becoming More Common
Across Lexington, Columbia, Irmo, Chapin, West Columbia, and surrounding Midlands communities, we’ve seen a noticeable increase in drought stress symptoms during periods of extended heat.
Grass loses moisture through a process called evapotranspiration. As temperatures rise, the rate of water loss increases dramatically.
When turf cannot replace that moisture quickly enough, stress begins to develop.
The result is often a lawn that looks sick – even when no disease is present.
This is why the question, “Is it fungus or drought stress?” has become one of the most common concerns we have heard during our very dry and hot spring.
Signs Your Lawn May Be Experiencing Drought Stress
One of the easiest ways to determine whether you’re dealing with drought stress is to look for several common warning signs.
Footprints Stay Visible
Healthy turf springs back after being stepped on.
Drought-stressed grass often remains flattened, leaving footprints visible long after you’ve walked across the lawn.
Gray or Blue-Green Coloring
Before grass turns brown, it frequently develops a dull blue-gray appearance.
This subtle color change is often one of the earliest indicators that the lawn needs additional moisture.
Dry, Hard Soil
If the soil feels hard and compacted or is difficult to penetrate with a screwdriver, your lawn may not be receiving adequate water.
Irregular Brown Areas
Drought stress often follows irrigation patterns.
You’ll frequently notice brown patches developing in areas that receive less coverage while nearby sections remain green.
Why Irrigation Coverage Matters More Than Most Homeowners Realize
One of the biggest issues we discovered at the Lexington property wasn’t necessarily the amount of water being applied.
It was how the water was being distributed.
A properly designed irrigation system should provide what professionals call head-to-head coverage.
This means one sprinkler head should effectively reach the next sprinkler head.
Why is this important?
Because sprinkler systems don’t apply water evenly across their entire spray pattern.
Without proper overlap:
- Dry spots develop
- Turf stress increases
- Brown patches appear
- Homeowners mistake drought stress for fungus
- Lawn recovery becomes more difficult
In this case, adjustments to the irrigation system were necessary to improve coverage and eliminate the dry zones that were stressing the turf.
Water Deeply, Not Daily
When homeowners see brown grass, many respond by watering every day.
Unfortunately, this can create another problem.
Frequent, shallow watering encourages shallow root systems.
Shallow roots struggle during extreme heat because they cannot access moisture deeper in the soil profile.
Instead, healthy turf benefits from:
Deep Watering
Apply enough water during each irrigation cycle to soak the root zone thoroughly.
Infrequent Watering
Allow the soil to dry slightly between watering events.
This encourages roots to grow deeper, creating a stronger and more drought-tolerant lawn.
Think of it this way:
A lawn that receives a deep drink a few times per week will typically outperform a lawn receiving small daily sips.
Is It Fungus or Drought Stress? Why Proper Diagnosis Matters
One of the reasons homeowners struggle to answer the question, “Is it fungus or drought stress?” is because several lawn problems can produce similar symptoms.
Brown patches may be caused by:
- Drought stress
- Irrigation deficiencies
- Soil compaction
- Lawn fungus
- Insect damage
- Nutrient deficiencies
- Root problems
That’s why a professional inspection can save both money and frustration.
Applying fungicides to a drought-stressed lawn won’t fix the issue.
Likewise, increasing irrigation won’t solve a genuine fungal outbreak.
The key is identifying the true cause before investing in treatments.
