How Lawns and Shrubs Handle Cold Weather in Florida
Florida is known for its warm, sunny climate and lush greenery that flourishes year-round. However, when winter approaches and temperatures drop, even Florida’s lawns and shrubs can be affected. While the state does not experience the harsh freezes seen in more northern climates, cold snaps can still stress plants, especially those not adapted to lower temperatures. In this blog, we will explore how Florida lawns and shrubs respond to cold weather and share tips for protecting and maintaining your landscape during the cooler months. For all your lawn and shrub care needs, Hannan Environmental Services is here to help.
How Cold Weather Affects Florida Lawns
Even in Florida, winter can bring temperatures that dip into the 30s or 40s. These cooler temperatures can lead to dormancy or damage to lawns and shrubs.
1. Dormancy in Warm-Season Grasses
Most Florida lawns consist of warm-season grasses such as St. Augustine, Bermuda, or Zoysia. These grass types are well-suited to the hot and humid Florida climate but can enter a state of dormancy when temperatures fall below 55°F. Dormant grass will appear brown and lack growth but is not dead. Dormancy is a natural survival mechanism that allows the grass to conserve energy during cooler weather.
What to Expect: Your lawn may not need as much mowing or watering during this period. While the brownish hue might be aesthetically disappointing, it is temporary and expected during colder weather.
2. Cold Damage and Frost
A sudden drop in temperature can cause frost to form on lawns, potentially leading to leaf burn or damage. Frost occurs when moisture in the air condenses and freezes on contact with grass blades. This can disrupt the cell structure of the grass, leading to patches of damage.
Prevention Tip: Watering your lawn lightly before a forecasted frost can help reduce damage. Moist soil holds more heat than dry soil, which can protect grass blades from freezing.
How Cold Weather Affects Shrubs in Florida
Shrubs in Florida are often more sensitive to cold than lawns. The impact on shrubs varies based on their type and origin—native Florida plants are generally more cold-hardy compared to non-native tropical varieties.
1. Cold-Hardy vs. Non-Hardy Shrubs
Native shrubs such as saw palmetto, yaupon holly, and wax myrtle are adapted to Florida’s winter weather and typically handle cooler temperatures well. However, tropical shrubs like hibiscus, croton, and bougainvillea are more vulnerable to cold and can sustain damage if temperatures dip too low.
Signs of Cold Damage: Cold-sensitive shrubs may exhibit wilting, leaf discoloration, or leaf drop. In severe cases, branches or stems may become blackened or brittle.
2. Frost Protection for Shrubs
If frost is expected, covering your shrubs with lightweight fabric such as burlap or frost cloth can protect them from cold damage. Ensure that the covering extends to the ground to trap heat rising from the soil. Avoid using plastic, as it can trap moisture and lead to further damage.
Pro Tip: Watering shrubs in the morning before a cold snap can help them retain heat and reduce the risk of frost damage.
Maintenance Tips for Lawns and Shrubs During Winter
Maintaining the health of your lawn and shrubs during winter requires proactive care. Here are some tips to ensure your landscape stays resilient:
- Adjust Watering and Fertilizing: Overwatering during colder months can do more harm than good. Reduce watering to once every week or two, depending on rainfall. Avoid heavy fertilization during winter, as this can encourage growth that is vulnerable to frost.
- Mow Less Frequently: As grass growth slows during winter, there is less need for mowing. Keeping grass at a slightly taller height can also help protect the roots from cold weather.
- Prune Carefully: Avoid heavy pruning right before winter, as new growth can be more susceptible to cold damage. Instead, wait until the risk of frost has passed before trimming shrubs.
- Use Mulch: Applying a layer of mulch around the base of shrubs can help insulate the roots and retain warmth in the soil. This is especially beneficial for cold-sensitive plants.
- Monitor Weather Forecasts: Stay informed about potential cold snaps or frost warnings so you can take protective measures when needed.
