An irrigation system that is maintained on a seasonal schedule lasts longer, uses less water, and keeps your landscape healthier. In Orlando, the maintenance calendar follows the region’s distinct wet and dry seasons rather than the four-season cycle familiar in colder climates. Here is a practical checklist organized by season.
Spring (March–May): Preparing for the Dry Season
Spring is the tail end of Orlando’s dry season and the beginning of the transition to summer. This is the most important time to make sure your system is ready for the heat.
Inspect every zone. Run each zone manually and walk the property. Look for heads that are not popping up, geysers, misaligned nozzles, and dry spots. Replace broken or clogged heads as needed. Costs for a single head replacement typically run $25 to $75. Check the controller settings and update the schedule for longer spring days. Confirm that the rain sensor is functioning. Florida law requires it, and a failed sensor means the system may run during rain. Our article on rain sensors and smart controllers covers the details. Check the backflow assembly for visible damage and confirm that the annual test is current. Our guide on backflow prevention and testing explains the requirement. Inspect the soil moisture in turf areas and adjust run times if the lawn is showing drought stress.
Summer (June–September): Managing the Wet Season
Summer brings frequent afternoon thunderstorms and high humidity. Irrigation demand actually drops during this period, but system problems can be harder to spot because the lawn stays green.
Reduce run times on the controller to account for rainfall. If you have a smart controller, it will adjust automatically. If you have a standard controller, manually reduce the schedule. Check for fungus and disease in turf areas, which are more common when soil stays wet. Look for signs of over-watering, including soggy patches and mushroom growth. Inspect the system after major storms. Lightning is a common cause of controller and wiring failure in Central Florida. Our guide on storm prep covers post-storm inspection. Clear debris from around heads and valves. Keep an eye on the water bill. An unexplained increase may indicate a leak or a stuck valve. Our sprinkler repair guide covers diagnosis.
Fall (October–November): Transitioning to the Dry Season
Fall marks the beginning of Orlando’s dry season. Rainfall drops, temperatures moderate, and irrigation demand gradually increases. This is a good time for a thorough system evaluation.
Increase run times gradually as rainfall decreases. Have the system evaluated by a licensed contractor if it has been more than a year since the last full inspection. Check the backflow assembly and schedule the annual test if it is due. Clean filters on drip zones, especially if you use reclaimed water. Our article on reclaimed water for irrigation covers the filtration requirements. Inspect the controller for any signs of wear or water intrusion. Check the rain sensor and clean it if necessary.
Winter (December–February): Freeze Preparation and System Check
Winter in Orlando is mild, but hard freezes do occur. A freeze can damage backflow assemblies, above-ground piping, and pump systems.
Before a forecast freeze, shut off the irrigation system. Drain the backflow assembly if it is above ground, or insulate it. Protect exposed piping with insulation. Do not run the system during a freeze. After the freeze, inspect for cracked components before restarting. This is also a good time to review the year’s water bills and compare usage to previous years. A gradual increase may indicate a slow leak or declining system efficiency. If the system is more than fifteen years old, consider whether a full replacement or major upgrade is warranted. Our installation cost guide covers pricing. And for the design principles that make a system efficient, see our article on drip irrigation vs. spray heads.
Year-Round Habits
Some tasks apply regardless of season. Check the controller after power outages to confirm the schedule and time are correct. Walk the property after heavy rain to look for drainage problems. Keep mulch away from sprinkler heads so they operate freely. And keep a record of repairs and maintenance so you can track the system’s history. If you are considering a system upgrade or a major repair, our guide on sprinkler repair in Orlando covers common issues. For the soil and water conditions that shape every decision, see our article on Orlando’s sandy soil.
The Bottom Line
A seasonal maintenance routine takes a few hours per season and prevents most of the problems that lead to expensive repairs. In Orlando, where irrigation is essential for most of the year, that routine is one of the highest-return home maintenance tasks available. Follow the checklist, keep records, and address small problems before they become large ones.
