How To Care for Sod and Plants During a Drought
Drought conditions can quickly put stress on lawns, plants, shrubs, and trees — especially throughout the Southeast, where high temperatures, sandy soils, and long periods of heat can dry landscapes out rapidly.
For homeowners and commercial property owners alike, drought stress doesn’t just affect appearance. It can lead to long-term plant damage, weakened root systems, increased pest problems, and expensive landscape replacement costs if not managed properly.
The good news is that healthy sod and plants can often survive drought conditions with the right care and watering strategies. The key is focusing on efficient watering, reducing stress, and protecting root systems rather than simply applying more water.
Understanding Drought Stress in Landscapes
During drought conditions, plants begin conserving water by slowing growth and redirecting energy toward survival.
Common signs of drought stress include:
Wilting leaves
Browning grass
Curling turf blades
Leaf drop
Slow growth
Dry or compacted soil
Footprints remaining visible in turf
Premature dormancy
According to the University of Florida IFAS Extension, drought stress is especially common in sandy Southeast soils because water drains quickly and nutrients leach away faster than in heavier soils. Understanding these stress signs early can help prevent permanent damage.
Water Deeply and Infrequently
One of the most common mistakes during drought is frequent shallow watering. Shallow watering encourages weak root systems that dry out faster and become more vulnerable to heat stress.
Instead, experts recommend watering deeply and less often to encourage roots to grow deeper into the soil.
Deep Watering Benefits:
Promotes stronger root growth
Improves drought tolerance
Reduces evaporation loss
Encourages healthier turf and plants
The University of Georgia Extension recommends applying enough water to moisten the root zone rather than simply wetting the soil surface.
For most lawns, this generally means about 1 to 1.5 inches of water per week, including rainfall, though requirements vary based on grass type, soil conditions, and local restrictions.
Water Early in the Morning
Timing matters just as much as the amount of water applied.
Early morning irrigation is typically the most effective because:
Temperatures are cooler
Winds are lighter
Evaporation is reduced
Plants can absorb moisture before peak heat
Watering during midday often leads to significant evaporation loss, while nighttime watering may increase fungal disease risk due to prolonged moisture on leaves and turf.
The Environmental Protection Agency (EPA) WaterSense Program recommends watering during early morning hours whenever possible to improve efficiency.
Raise Your Mowing Height
During drought conditions, mowing grass too short can severely stress turf.
Taller grass blades:
Shade the soil
Reduce evaporation
Protect roots
Improve moisture retention
Most university turf programs recommend increasing mowing height slightly during hot, dry periods.
Avoid:
Scalping lawns
Removing too much grass at once
Mowing during extreme heat
The North Carolina State Extension notes that maintaining proper mowing height is one of the simplest ways to improve drought tolerance in warm-season grasses.
Reduce Foot Traffic on Drought-Stressed Turf
Dry turf becomes more vulnerable to physical damage during drought.
Heavy foot traffic can:
Crush weakened grass blades
Compact dry soil
Damage root systems
Slow recovery
For commercial properties, apartment communities, HOAs, and sports areas, reducing unnecessary traffic on stressed turf can significantly improve recovery once rainfall returns.
Mulch Around Plants and Trees
Mulch is one of the most effective tools for protecting plants during drought.
Proper mulch helps:
Retain soil moisture
Regulate soil temperature
Reduce evaporation
Suppress weeds
Improve soil health over time
The Clemson Cooperative Extension recommends maintaining approximately 2–3 inches of mulch around landscape plants while keeping mulch away from direct contact with trunks and stems.
Good mulch options include:
Pine bark
Pine straw
Hardwood mulch
Eucalyptus mulch
Avoid excessive mulch buildup, often called “volcano mulching,” which can trap moisture against trunks and encourage disease.
Prioritize Newly Installed Sod and Plants
New sod, shrubs, and trees are especially vulnerable during drought because their root systems have not fully established.
Recently installed landscapes often require:
More frequent watering
Closer monitoring
Temporary irrigation adjustments
New sod may need daily watering during establishment depending on temperatures and local conditions.
According to university extension programs, the first several weeks after installation are critical for root establishment and long-term survival.
If water restrictions exist, prioritize:
Newly planted trees
New shrubs and plants
Newly installed sod
Mature established turf
Established landscapes can often survive temporary drought better than newly planted material.
Avoid Excessive Fertilization During Drought
Many homeowners assume fertilizer will “green up” stressed landscapes during drought, but fertilizing drought-stressed plants can sometimes make conditions worse.
Excess fertilizer may:
Increase plant stress
Burn roots
Stimulate weak growth
Increase water demand
The Texas A&M AgriLife Extension advises avoiding heavy fertilization during severe drought conditions unless recommended based on soil testing. Focus first on moisture management and plant health rather than rapid growth.
Check Irrigation Systems Regularly
Irrigation inefficiency becomes much more costly during drought conditions.
Common problems include:
Broken sprinkler heads
Leaking lines
Overspray onto pavement
Uneven coverage
Incorrect timer settings
The Environmental Protection Agency (EPA) estimates that a significant percentage of residential irrigation water is wasted due to system inefficiencies and overwatering. Regular irrigation inspections can improve water conservation while helping landscapes survive drought more effectively.
Understand Dormancy vs. Death
Not all brown grass is dead. Many warm-season grasses common throughout Florida, Georgia, South Carolina, and North Carolina naturally enter dormancy during prolonged drought to conserve energy.
Dormant grass often:
Turns brown temporarily
Stops active growth
Recovers after rainfall or proper irrigation
However, prolonged severe drought without adequate moisture can eventually kill turf and plants. A landscape professional or local extension office can help determine whether turf is dormant or permanently damaged.
Consider Drought-Tolerant Landscaping
Long-term drought management often involves selecting plants better adapted to local climate conditions.
Drought-tolerant landscapes may include:
Native plants
Deep-rooted shrubs
Warm-season turf varieties
Efficient irrigation systems
Mulched planting beds
The American Society of Landscape Architects (ASLA) encourages sustainable landscape planning that reduces water demand while improving long-term landscape resilience.
For Southeast coastal regions, selecting plants adapted to heat, humidity, and periodic drought can significantly reduce maintenance requirements.
Final Thoughts
Drought conditions can be stressful for both landscapes and property owners, but proper care can help sod and plants survive and recover successfully.
The most effective drought-care strategies include:
Deep, efficient watering
Proper mowing practices
Mulching
Irrigation management
Reducing plant stress
Prioritizing newly installed landscapes
For homeowners and commercial property owners alike, proactive drought management can help protect landscape investments, reduce replacement costs, and maintain healthier outdoor spaces during periods of extreme heat and limited rainfall.
