How Often Should You Water Your Florida Lawn in Winter?
Winter in Florida may not bring snow, but cooler temperatures still change how your lawn needs to be watered. One of the most common mistakes homeowners make is continuing their summer watering schedule through winter. In reality, Florida lawns need far less water during the winter months.
How Often Should You Water in Winter?
Most Florida lawns only need watering once every 10–14 days during winter. In some cases, you may not need to water at all if rainfall is sufficient.
Grass grows more slowly in cooler weather, evaporation is reduced, and soil stays moist longer. Overwatering during this time can actually harm your lawn more than help it.
Why Overwatering Is a Problem in Winter
Excess water in winter can lead to:
Fungal diseases
Root rot
Weak, shallow root systems
Thinning or yellowing grass
Allowing the soil to dry slightly between waterings keeps roots healthy and reduces disease pressure.
How Much Water Is Enough?
When you do water, apply ½ to ¾ inch of water in a single session. This allows moisture to reach the root zone without saturating the soil.
A simple way to measure this is by placing a few small containers around your yard while watering. Once they reach ½ to ¾ inch, you’ve applied enough water.
Signs Your Lawn Needs Water
Instead of watering on a set schedule, watch for signs of stress:
Grass blades folding lengthwise
A bluish-gray or dull color
Footprints that remain visible after walking on the lawn
If you don’t see these signs, your lawn likely doesn’t need water.
Best Time of Day to Water
The best time to water your Florida lawn in winter is early in the morning, after sunrise. This gives the grass time to dry during the day and reduces the risk of fungal diseases that thrive in cool, damp conditions.
Avoid watering in the evening or at night.
Winter Watering by Grass Type
St. Augustine: Very sensitive to winter overwatering; water sparingly
Bermuda: Often goes dormant; requires minimal watering
Zoysia: Low water needs in winter
Bahia: Extremely drought-tolerant; water only if stressed
Don’t Forget Rainfall & Local Restrictions
Cold fronts often bring rain during Florida winters, which can replace scheduled irrigation. Many Florida communities also enforce year-round watering restrictions, so be sure to follow local guidelines.
Final Thoughts
When it comes to winter lawn care in Florida, less is more. Water only when your lawn shows signs of stress, usually every 10–14 days or less, and always water deeply.
Adjusting your winter watering routine now will help your lawn stay healthier, greener, and more resilient when spring arrives.
