Prepare your Landscape for Freezing Temps
Preparing Your Landscape for a Freeze
Harsh winter weather can be tough on your plants, but with the right preparation, your landscape can thrive all season. In this post, we cover the essentials of freeze protection—like watering thoroughly before the cold hits, insulating roots with mulch, and using the proper covers for different temperature ranges. We also highlight which plants are most vulnerable and offer tips on how to keep them safe. Whether you’re worried about light frosts or severe freezes, these key takeaways will help you protect your yard and ensure a healthier, more resilient outdoor space.
Water Thoroughly
Moist soil stays warmer longer. Always water in-ground and potted plants before a freeze.
Freeze Duration & Timing
Longer freezes cause more damage.
Early or late-season cold snaps are tougher on plants not fully dormant.
Plant Age & Growth Stage
Young or newly planted trees/shrubs are more vulnerable.
Fresh new growth is more susceptible to cold damage.
Location & Surroundings
Isolated, standalone plants face colder conditions than those under tree canopies.
Potted or raised-bed plants are at higher risk due to exposed roots.
Mulch for Insulation
Apply a 2" mulch layer around roots (but not against trunks).
Conserves soil heat and helps moderate temperatures.
Covering Plants
Use blankets, frost fabric, or sheets anchored to the ground—this traps ground warmth.
If using plastic, place it over cloth layers, never directly on foliage.
Temperature “Rules of Thumb”
Around 40°F (possible frost): Protect tender growth or blooming perennials if you want to save flowers.
32°F for a few hours: Plants rated Zone 8b or lower are usually fine. Cover tender Zone 9–10.
Below 28°F (4+ hours): Protect “marginally tender” plants; the colder/longer it is, the more need covering.
Below 20°F (severe cold): Even hardy plants can suffer, depending on health, age, and exposure.
Common Vulnerable Species
Examples: Sago Palm, Agave, Bottlebrush, Camellia, Oleander, Texas Sage, and other subtropicals.
Herbaceous perennials (e.g., Esperanza, Pride of Barbados) may die back but often regrow if well-mulched.
Conclusion
A little planning and proactive care go a long way in safeguarding your landscape from winter’s challenges. By keeping your soil well-hydrated, adding protective mulch, and following smart covering techniques, you’ll help your plants weather the cold and bounce back stronger when temperatures rise. Pay special attention to the most vulnerable species, and when in doubt, consult hardiness zones or reach out to a professional for guidance. With these steps in place, you can maintain a healthy, vibrant outdoor space—even in the face of unpredictable Central Texas freezes.
