How to Protect Your Plants and Landscape From Freezes in North Texas

When the temperature dips below freezing in North Texas, your lawn, trees, and landscape plants are at risk — especially if they aren’t prepared. At GroProMan Horticulture, we specialize in mitigating freeze damage by combining horticultural expertise with proactive care. Here’s how you can protect your plants, preserve your landscape, and avoid costly damage when a cold snap hits.

Understand the Risk: What Freezes Do to Your Landscape

Freezes can damage plant cells, crack bark, and disrupt root function. Rapid temperature drops cause ice crystals to form inside plant tissues, which can rupture cell walls and kill leaf tissue. In worse cases, freeze damage weakens branch structure or kills young plants altogether. For landscapes that haven’t had winter prep, these problems can escalate fast.

Choose Freeze-Resilient Plants (When Planning)

One of the most effective defenses starts before the freeze even happens:

• Opt for hardy species. Native plants and drought-tolerant varieties often survive freezes better.

• Use proper spacing. Plants spaced too closely are more stressed and prone to freeze damage.

Prioritize mulch. Add a 2–3 inch layer of organic mulch around the base of plants to insulate soil and protect roots from extreme cold.

Pre-Freeze Irrigation: It Matters

Use Protective Coverings for Key Plants

Watering before a freeze may sound counterintuitive, but it’s a proven technique:

• Moist soil holds more heat than dry soil, which moderates temperature swings.
• Avoid watering too late — stop irrigation a day in advance to prevent wet foliage from freezing.
• Use deep, infrequent watering so roots are established, which helps greater freeze resilience.

Prune Strategically Before Freeze Season

For sensitive or newly established plants, temporary protective measures make a big difference:

• Use frost cloths, blankets, or breathable covers (not plastic, which traps moisture).
• Anchor the cloth to the ground to trap heat from the soil.
• Remove covers during the day if temperatures rise, to avoid overheating or disease issues.

Monitor Temperature and Act Quickly

Stay alert when freeze warnings are in effect:

• Use a weather app or local forecast to know when freezes are likely.
• If freezing is expected, cover vulnerable plants early in the evening.
• After a freeze, inspect plants for damage and remove any shattered or split wood promptly to prevent disease.

When to Call the Experts

Some plants and trees require professional care, especially after a damaging freeze. Contact GroProMan Horticulture if you:

• Have large or high-value trees with possible bark splits or root damage
• Need help choosing the right plants for freeze-prone areas
• Want a pre-winter consultation and service plan (fertilization, aeration, structural pruning)
