5 Reasons You MUST Turn Your Sprinklers Off During Winter From the Dirt Doctors at Brooks Landscaping
When winter settles into Paulding County, most homeowners assume their landscaping can simply “coast” until spring. But here’s the truth: your irrigation system and your yard still need the right kind of winter care—and one of the most important steps you can take is turning your sprinklers OFF during the wintertime.
At Brooks Landscaping — “We Make Dirt Look Good™”, we specialize in designing, maintaining, and protecting landscapes that are designed to drain and built to last. And every winter, we see the same costly mistakes… homeowners unknowingly damaging their lawns, irrigation systems, and soil structure simply because the sprinklers were left on.
Today, The Dirt Doctor breaks down the five major reasons why shutting down your sprinkler system is not optional—it’s necessary.
1. Prevent Root Rot and Winter Fungal Growth
During the winter months, your lawn naturally enters a dormant phase to conserve energy. Growth slows, grass blades tighten, and roots rest. When sprinklers are left running:
-
Soil becomes oversaturated
-
Roots are deprived of oxygen
-
Fungal diseases (like brown patch or gray leaf spot) spread
-
Turf health declines long before spring returns
This is especially important for Zeon Zoysia, Bermuda, and Fescue lawns common in Dallas, Hiram, Kennesaw, and Acworth. These grasses require significantly less moisture in cold weather.
Too much water + cold soil = root suffocation and long-term lawn damage.
Shutting off your sprinklers protects your turf from avoidable disease and costly spring restoration work.


2. Protect Your Irrigation System From Freeze Damage
When temperatures drop into the low 30s—even briefly—any remaining water inside your irrigation lines can:
-
Expand
-
Freeze
-
Crack PVC and poly pipes
-
Burst sprinkler heads
-
Damage backflow preventers
In Paulding County, nights can dip low enough to create pressure buildup inside lines, leading to expensive repairs.
Replacing cracked irrigation lines often costs far more than a simple winter shutoff.
A frozen backflow preventer alone can run hundreds of dollars to fix.
Turning sprinklers off during winter protects your investment and keeps your system ready for spring activation.


3. Avoid Water Runoff, Erosion, and Drainage Issues
At Brooks Landscaping, we are Paulding County’s drainage and erosion control experts, and we see wintertime irrigation mistakes cause:
-
Standing water
-
Muddy patches
-
Soil compaction
-
Washouts
-
Foundation drainage problems
-
Increased water flow toward patios, driveways, and crawlspaces
Winter rain already keeps the soil moist. Adding extra irrigation pushes water to areas where it doesn’t belong.
If your property already has marginal grading or slow-draining clay soil, running sprinklers in winter creates unnecessary drainage problems that can:
-
Kill grass
-
Damage landscape beds
-
Threaten home foundations
-
Require expensive drainage repairs (French drains, grading, dry creek beds, etc.)
Simply shutting off irrigation prevents oversaturation during Georgia’s rainiest months.


4. Your Lawn Doesn’t Need the Extra Water in Winter
This point surprises many homeowners:
Dormant lawns need almost zero supplemental water during winter months.
In Georgia, natural rainfall is more than enough to support:
-
Zeon Zoysia
-
Emerald Zoysia
-
Bermuda grass
-
Tall Fescue
Overwatering in winter interrupts natural dormancy cycles and weakens spring recovery.
By turning your sprinklers off, you help your lawn:
-
Preserve carbohydrate stores
-
Strengthen root systems
-
Wake up healthier in spring
-
Resist pests, weeds, and thatch buildup
A healthier spring lawn starts with smarter winter watering practices.

5. Lower Your Water Bill — And Protect the Environment
Why pay for water your lawn doesn’t need?
Keeping your irrigation system running in the winter leads to:
-
Unnecessary utility costs
-
Water waste
-
Stress on municipal water systems
-
Higher monthly bills
Many Georgia homeowners see their water bills drop instantly once they winterize their irrigation.
Turning sprinklers off is not just a smart financial move—it’s a responsible landscape practice for Paulding County homeowners.
How to Properly Turn Off Your Irrigation System
To protect your system fully, Brooks Landscaping recommends:
1. Shut off the irrigation water supply
Prevents freeze expansion in the main lines.
2. Turn off the controller (or put it in “rain mode”)
3. Drain or blow out lines if needed
4. Insulate above-ground components
Backflow preventers and exposed piping are the first to freeze.
5. Inspect valves and heads for spring readiness
If you want the Dirt Doctor team to handle your winter irrigation shutdown, we service homeowners across Dallas, Hiram, Acworth, Kennesaw, and the greater Paulding County area.
Why Winter Watering Mistakes Lead to Expensive Spring Problems
Leaving sprinklers on all winter often results in:
-
Patchy turf
-
Soil erosion
-
Oversaturated muddy zones
-
Fungus outbreaks
-
Weak spring green-up
-
Costly irrigation repairs
These issues lead many homeowners to call us for emergency repairs in March and April—problems that could have been avoided with a simple system shutoff.
