How to Tell if Winter Weather Is Damaging Your Grass

When cooler temperatures arrive, many homeowners assume their lawn can be ignored until spring. After all, grass growth slows, mowing becomes less frequent, and everything looks… dormant. But winter is not a “pause button” for your lawn. In fact, what happens to your turf during colder months plays a major role in how healthy and green it will be once warmer weather returns.

Winter weather can stress grass in subtle ways, from frost damage and root weakness to weed invasions that won’t show themselves until spring. The challenge is knowing the difference between normal seasonal dormancy and true winter injury. Brown grass doesn’t always mean dead grass—but sometimes it does.

Understanding the signs of winter damage, how lawns naturally respond to cold and what steps you should (or shouldn’t) take during this time can make the difference between a lawn that struggles in spring and one that thrives.

Why Winter Lawn Care Still Matters

Even though grass grows more slowly in winter, it remains biologically active beneath the surface. During cooler months, turfgrass shifts its focus away from leaf growth and concentrates on strengthening its root system. Those roots store energy, repair stress damage and prepare for vigorous growth once temperatures rise.

If your lawn lacks nutrients, protection or proper care during this period, it enters spring already at a disadvantage. Thin turf, weakened roots and winter weeds can quickly take over, making recovery more difficult and expensive.

That’s why winter lawn care isn’t about forcing growth—it’s about protection, preparation and patience.

Dormancy vs. Damage: Knowing the Difference

One of the most common winter lawn concerns is discoloration. Grass may turn brown, tan or dull green during cold weather, especially following frost or freezing temperatures. While alarming, this change in color is often part of the lawn’s natural dormancy process.

Dormant grass conserves energy by slowing growth and limiting nutrient use. This is especially common in warm-season grasses, which naturally lose color as temperatures drop.

However, winter damage looks different from dormancy—and the difference matters.

Signs of Normal Dormancy

• Grass blades turn uniformly brown or straw-colored
• Turf still feels firmly rooted when gently tugged
• Lawn greens up gradually as temperatures warm
• No bare soil or thinning patches appear

Signs of Possible Winter Damage

• Irregular brown or gray patches
• Grass pulls out easily from the soil
• Areas fail to green up by early spring
• Thinning turf or exposed soil
• Mushy, brittle or straw-like grass texture

The key takeaway? A brown lawn in winter isn’t automatically a dead lawn. Many lawns rebound naturally once conditions improve.

Frost and Freeze Damage: What to Look For

Freezing temperatures can injure grass, trees and shrubs—especially during sudden cold snaps or extended freezes. Frost damage often appears quickly, but the full extent may not be obvious until weeks or even months later.

How Frost Affects Grass

• Ice crystals form inside plant cells, causing rupture
• Grass blades may appear water-soaked or limp
• Repeated freeze-thaw cycles weaken turf structure

After a freeze, grass may look worse before it looks better. As temperatures rise, areas that survived will slowly recover. Sections that remain brown well into spring may indicate permanent damage.

It’s important to wait before acting. Rushing to prune, mow or fertilize too soon can make the damage worse.

When to Wait—and Why Patience Pays Off

After a frost or freeze, it’s natural to want to “fix” your lawn immediately. But timing matters.

Avoid These Common Mistakes

• Pruning too early: Cutting back damaged plants too soon can stimulate tender new growth that’s vulnerable to additional cold injury.
• Over-fertilizing: Applying fertilizer immediately after a freeze won’t revive damaged grass and can stress weakened roots.
• Mowing too low: Scalping cold-stressed grass makes recovery more difficult.

As temperatures warm in spring, healthy portions of your lawn will begin to grow out of any winter injury. Areas that don’t recover by late March or early April may need additional attention or replacement.

---

Winter Damage Isn’t Always Immediate

Some cold-related injuries take time to show up—especially in trees and shrubs around your lawn. In some cases, damage from freezing temperatures may not become visible until months later.

Signs of Delayed Cold Injury

• Dieback in branches during late spring or summer
• Cracked or splitting bark on trunks
• Stunted growth or leaf loss well after winter ends

Inspecting tree trunks is particularly important. If freezing temperatures have damaged the tissues responsible for transporting water and nutrients, the plant’s long-term health may be compromised.

Protecting Plants During Cold Weather

While grass is fairly resilient, some plants need extra protection during extreme cold events.

Cold Protection Tips

• Cover sensitive plants with blankets, sheets or boxes
• Avoid plastic coverings, which trap moisture and increase freeze damage
• Remove coverings as soon as temperatures rise to prevent overheating

These small steps can prevent significant injury and reduce recovery time in spring.

Winter Weeds: The Hidden Threat Beneath Your Lawn

One of the most overlooked forms of winter lawn damage isn’t damage at all—it’s competition.

Certain weeds thrive in cooler weather and take root during winter months, quietly establishing themselves while your grass is dormant. Without proper preventative care, these weeds explode in spring and crowd out healthy turf.

Why Pre-Emergent Treatments Matter

• Prevent winter weeds from germinating
• Reduce spring weed infestations
• Protect turf density and appearance

Without pre-emergent protection, weeds like annual bluegrass can dominate your lawn long before you realize there’s a problem.

---

Strengthening Roots Before Spring

A healthy lawn starts below the surface. Fertilizing during cooler months helps grass develop deeper, stronger roots that improve stress tolerance and spring performance.

Winterizing fertilizers are specially formulated to:

• Support root development
• Improve cold tolerance
• Store nutrients for spring green-up

This approach doesn’t force top growth—it prepares the lawn for what comes next.

There’s also no benefit to applying extra fertilizer immediately after a freeze. Grass needs time to recover naturally. Spring fertilizer applications are best timed for late winter or early spring, when growth resumes.

---

Mowing After Winter: Do It the Right Way

As your lawn begins to recover, mowing should resume gradually and carefully.

Best Practices for Post-Winter Mowing

• Wait until grass shows signs of active growth
• Set mower blades to the highest recommended height
• Avoid removing more than one-third of the blade at a time

Cutting grass too short after winter stress can weaken recovery and invite weeds.

---

When Replacement Is Necessary

Sometimes, despite your best efforts, certain areas of the lawn don’t recover. If patches remain bare or lifeless well into spring, partial replacement may be necessary.

Sod pieces can be used to:

• Repair damaged sections
• Restore lawn uniformity
• Prevent erosion and weed invasion

The good news? Most winter-damaged lawns only need spot repairs—not full replacement.

A professional program ensures your lawn receives:

• Seasonally appropriate fertilization
• Preventative weed control
• Expert monitoring for cold stress
• Customized treatments based on turf type and climate

With Massey Services’ GreenUP Landscape program, your lawn receives a winterizing fertilizer blend designed to strengthen plants against cold temperatures while encouraging quicker green-up in spring.
