For HOAs and commercial properties in Southwest Florida, winter irrigation is not a “set it and forget it” task. Even in mild climates like Naples, Fort Myers, Bonita Springs, Estero, and Port Charlotte, cooler temperatures and shorter days significantly reduce plant water needs. Without proper winter irrigation adjustments, properties often overspend on water while stressing turf and ornamentals. When we use the term “winter” in Southwest Florida, we are talking about the months of December, January and February. 

Evapotranspiration (ET)–based scheduling is a proven strategy to align irrigation runtimes with actual plant demand, leading to healthier landscapes and more predictable budgets.

Why Winter Irrigation Adjustments Matter in Southwest Florida

Many irrigation controllers in Southwest Florida are set for peak summer conditions and never adjusted again. In winter, this can result in:

  • Overwatering and turf diseases
  • Shallow root systems and weaker turf
  • Runoff and standing water around sidewalks and curbs
  • Higher water bills for communities and commercial centers

In cities like Naples and Fort Myers, winter brings:

  • Reduced ET rates
  • Lower soil evaporation
  • Slower turf and plant growth

Adjusting irrigation schedules to match these conditions is one of the most cost-effective ways to improve landscape performance across your Southwest Florida property.

What Is ET Scheduling and Why Should HOAs Care?

Evapotranspiration (ET) is the combined loss of water from soil evaporation and plant transpiration. When ET is high in summer, landscapes need more water. When ET is lower in winter (December, January and February), landscapes require significantly less.

ET-based irrigation scheduling uses this information to:

  • Adjust total water applied per week
  • Modify runtimes for different plant types
  • Fine-tune irrigation by microclimate (sun, shade, wind exposure)

For HOAs and commercial properties in Bonita Springs, Estero, and Port Charlotte, ET scheduling helps standardize irrigation decisions across multiple buildings, neighborhoods, or parcels.

Key Winter Irrigation Adjustments for Naples–Fort Myers Area Properties

A professional irrigation contractor serving Southwest Florida should review and adjust the following each winter:

1. Turf Zone Runtimes

Winter turf in our region grows more slowly and needs less water. Your contractor should:

  • Reduce total weekly runtime for turf zones
  • Monitor turf color and density after changes
  • Adjust by exposure: full-sun areas require more water than heavily shaded turf

2. Shrub and Bed Zone Frequencies

Shrub beds and ornamental plantings in Naples and surrounding markets often benefit from:

  • Fewer watering days per week
  • Carefully set runtimes to avoid soggy soil
  • Zone-specific adjustments for mulched, shaded, or protected beds

3. Irrigation Start Times and Cycles

In Southwest Florida winter conditions, best practice usually includes:

  • Early-morning irrigation cycles to reduce disease pressure
  • Shorter cycle times that minimize standing water
  • Cycle-and-soak programming in areas with slope or compacted soil

4. Smart Controllers and ET Data

If your property uses smart irrigation controllers, they can automatically adjust schedules based on ET data. Even with conventional controllers, a quarterly schedule review guided by ET trends can deliver substantial water savings and improved plant health.

Monitoring Performance After Winter Adjustments

Adjustments should be followed by on-site verification. A responsible irrigation partner will:

  • Inspect turf color and density across all major common areas
  • Check beds, entry features, medians, and amenity spaces for stress
  • Look for runoff, standing water, or dry hot spots
  • Document changes for HOA boards and property managers

This documentation is especially valuable for boards in Naples, Fort Myers, Bonita Springs, Estero, and Port Charlotte who must explain water use and landscape conditions to residents and owners.
