Spring has arrived in Northeast Florida. This means it’s time to get your irrigation system ready for work. Many homeowners put this task off. They face problems later when the dry season hits. Water bills skyrocket. Lawns turn brown. Plants wilt. But you can avoid these problems with proper preparation.
At Amelia Lawn & Landscaping Services, we help homeowners prepare their irrigation systems every year. We know what works and the common problems, and we want to share this knowledge with you.

When Should I Turn On My Sprinkler System in Northeast Florida?
Timing matters for irrigation startup. In Northeast Florida, late February to early March is the best time. You want to wait until frost danger passes. Your soil needs to reach at least 65°F for active grass growth.
Starting too early stresses your lawn. Starting too late gives weeds a head start. Watch for these signs that it’s time:
Several days of temperatures above 70°F
No frost in the forecast
Grass showing early growth
Soil feels warm to the touch
Proper timing is crucial for St. Augustine and Zoysia grass. These grass types thrive when irrigation systems work correctly from the start of their growth cycle.
Simple System Inspection Steps After Winter
Your irrigation system has been inactive all winter. It needs a thorough check before use. Follow these steps:
1. Look for Visible Damage
Walk your property. Check each sprinkler head. Look for:
Broken or cracked heads
Heads pushed below ground level
Heads blocked by new growth
Leaking pipes or connections
Problems are easier to fix now than mid-summer when water restrictions tighten.
2. Turn On the Water Slowly
Open your main water valve gradually. This prevents water hammer, which happens when water rushes into empty pipes and can break pipes and fittings.
Turn the valve one-quarter turn. Wait 30 seconds. Turn to another quarter. Continue until fully open.
3. Test Each Zone
Testing each zone helps you find issues before they damage your lawn. Here’s how:
Set your controller to manual mode
Run each zone for 3-5 minutes
Watch for proper head movement and spray patterns
Check coverage – look for dry spots or excessive overlap
Listen for unusual noises from the pump or pipes
4. Signs Your Sprinkler System Needs Repair After Winter
Some problems are not obvious until you test the system. Watch for these warning signs:
Low water pressure: Heads barely spray or don’t pop up fully
High water pressure: Misting or fogging instead of solid streams
Uneven coverage: Brown spots appear despite watering
Water pooling: Areas stay wet long after the system turns off
Sprinkler heads stuck: Heads don’t retract or rotate properly
Finding these issues early saves money and water. It also protects your lawn from stress.
How to Program Your Irrigation System for Florida Water Restrictions
Florida has strict water conservation rules. Your irrigation system must follow these guidelines:
Know Your Watering Days
In Northeast Florida, watering days depend on your address:
Even-numbered addresses: Thursday and Sunday
Odd-numbered addresses: Wednesday and Saturday
No watering between 10 AM and 4 PM
No watering on Monday, Tuesday, or Friday
Program these days into your controller. This keeps you compliant and avoids fines.
Adjust Run Times for Each Zone
Different areas need different amounts of water. Adjust each zone based on:
Sunny vs. shady areas (when it’s sunny, it needs more water)
Slope (sloped areas need shorter, more frequent cycles)
Soil type (sandy soil needs more frequent watering)
Plant types (established trees need less frequent watering than flowers)
Most lawns need about 3/4 inch of water per session. Measure output with a rain gauge or a tuna can.
Set the Right Start Time
Early morning is best for watering. Program your system to start between 4 AM and 9 AM. This timing:
Reduces evaporation
Allows water to soak in before the heat of the day
Prevents fungal growth that happens with evening watering
How to Check Sprinkler Coverage Patterns
Even coverage means a healthier lawn with fewer problems. Check your coverage with these steps:
Use the Catch Cup Test
A catch cup test measures how much water reaches different areas. You’ll need:
Several same-sized containers (tuna cans work well)
A ruler to measure water depth
Paper and pencil to record results
Place containers in a grid pattern across one zone. Run the zone for 15 minutes. Measure the water depth in each container. If some cups have much more or less water than others, your system needs adjustment.
Look for Signs of Poor Coverage
Water problems leave visible signs:
Dry spots in otherwise green areas
Extra green patches (too much water)
Water running onto sidewalks or driveways
Bare soil from excessive spray force
Fix Common Coverage Problems
After finding issues, make these adjustments:
Adjust the spray arc to cover only the lawn areas
Clean clogged nozzles with a small wire
Replace worn nozzles with matched precipitation rate models
Install pressure regulators if the pressure is too high
Add heads if coverage gaps exist
Are Rotating Sprinkler Heads Better Than Fixed Spray Heads?
Both head types have their place in a good irrigation system.
Fixed Spray Heads
Fixed spray heads work best for:
Small, flat areas
Uniform plant types
Areas under 15 feet in diameter
They provide:
Simple operation
Lower cost
Easy replacement
Rotating Heads
Rotating heads excel at:
Larger areas (15-35 feet)
Sloped terrain
Areas with trees or varied plants
Benefits include:
30% less water use than fixed heads
Better resistance to wind
Larger water droplets that soak in better
Less runoff on clay soils
The answer? Use the right head for each area. Many systems benefit from both types.
