Winter’s Effect on Lawns in Florida

Sod can be installed year-round in Florida, but winter conditions may affect how your lawn looks and grows.

Warm-season grasses naturally enter dormancy when soil temperatures drop below 50°F (note: this refers to soil temperature, not air temperature). In addition, shorter daylight hours slow growth. For example, December averages about 9 hours of daylight, compared to nearly 15 hours in July.

Your location within Florida also plays a role:

• North Florida (Orlando and above): Dormancy is very likely
  
• Central Florida (Orlando to St. Petersburg): Dormancy depends on seasonal temperatures
  
• South Florida (below St. Petersburg): Grass typically remains green unless there is a rare freeze
  

Winter Lawn Care

A common misconception is that lawns don’t need care during winter—they do, just with some adjustments:

• Continue watering, but reduce frequency due to slower evaporation
  
• Consider a light application of nitrogen-based fertilizer to maintain lawn health
  
• For weed control, products containing Atrazine can be used as both pre- and post-emergents
  
• Avoid applying liquid treatments right before a freeze—always check the forecast
  

Dormant Sod Guide

Why Does Sod Go Dormant?

• Warm-season grasses (such as Zoysia, Bermuda, and St. Augustine) go dormant in cooler temperatures
  
• Dormancy is a natural “resting” phase that protects the grass until warmer weather returns
  
• Growth slows or stops above ground, but roots remain alive and healthy
  
• A brown or golden color is normal—this does not mean the grass is dead
  

Benefits of Installing Dormant Sod

• Less stress compared to planting during Florida’s hot summer months
  
• Helps reduce mud, dust, weeds, and soil erosion
  
• Provides immediate curb appeal, even in dormancy
  

Caring for Dormant Sod

• Water is still essential, especially for newly installed sod
  
• Winter rainfall can help, but monitor for dry or windy conditions
  
• Ensure sod is installed on properly prepared soil with good root-to-soil contact
  

Spring Green-Up & Recovery

• Sod begins to “wake up” as soil temperatures rise above approximately 65°F
  
• Roots recover first, followed by new green growth
  
• Once active growth resumes, mow at your normal height to gradually remove any winter-damaged blades
  
• Wait until after the final frost before applying fertilizer
  
• Apply a pre-emergent herbicide in early spring (February–March) to prevent weed growth
  

Final Note

Dormant sod is a natural and healthy part of Florida lawns during cooler months. With proper winter care and spring maintenance, your lawn will return lush, green, and thriving.
