How to Tell if a Tree Survived Winter: Signs of Storm & Cold Damage in Charleston

Charleston winters can harm trees more than they seem. Even with mild temperatures, sudden freezes, ice storms, and high winds can cause hidden damage that takes months to show. To check if your tree survived, look for these key signs:

• Leaves: Freeze damage appears as brown, wilted, or scorched edges on evergreen leaves or needle tips.
• Bark: Cracks or peeling bark, especially near the trunk’s base or crown, signal cold stress.
• Branches: Dead branches snap easily, while live ones bend. Test by scratching bark to reveal green, moist tissue underneath.
• Roots: Uprooted soil or leaning trees may indicate root damage from storms.

If you notice damage, prune carefully in late winter or early spring. Remove dead branches but avoid cutting too early, as some issues take time to appear. For large or hazardous trees, hire a certified arborist to ensure safety and proper care.

Are My Trees Dead?! Or Just Winter Burn? (Simple Test to Know for Sure)

Signs of Freeze and Cold Damage

Freeze damage doesn’t always show up immediately – it can take hours, days, or even months for the full effects to appear. According to Clemson University Cooperative Extension, “the signs of cold damage can be confusing, since some damage may not be evident until months later”. This delayed onset makes early spring inspections crucial for homeowners in Charleston. When checking for damage, focus on leaves, branches, and bark for telltale signs.

Damaged Leaves and Foliage

Leaves and shoots are often the first to reveal freeze damage. Shortly after a freeze, foliage may appear water-soaked and wilted, only to turn black or brown within hours. Broadleaf evergreens, such as hollies, azaleas, and camellias, often develop “marginal leaf burn” – brown, scorched edges along the leaves. In contrast, narrow-leaved evergreens like junipers typically show browning at the needle tips.

Another common issue is “evergreen burn,” caused by winter winds. When frozen soil blocks water absorption, needles dry out and become crispy.

Tony Bertauski, a horticulture instructor at Trident Technical College, shared an example from March 2025: a mandarin tree in Charleston lost all its leaves after a cold snap but eventually recovered. Meanwhile, a Meyer lemon tree exposed to the same conditions did not survive. This highlights how different tree species can respond very differently to Charleston’s winter weather.

But the damage doesn’t stop at the leaves – freezing temperatures can also impact bark and trunk health.

Bark and Trunk Damage

Cold temperatures can wreak havoc on a tree’s bark, leading to structural problems. Frost cracks, also called “southwest injury”, are deep vertical splits that usually form on the south or southwest side of a tree’s trunk. These occur when the afternoon sun warms the bark, causing it to expand, followed by rapid contraction as temperatures drop at sunset.

In Charleston, bark splitting is often seen near the base or crown of trees due to sudden temperature swings. Splits at the crown are particularly concerning, as they can jeopardize the tree’s survival. Peeling or separated bark is another red flag. Press on the trunk to check for soft spots, which could indicate internal damage.

In early 2025, Spartanburg Tree Care dealt with a large maple tree in Landrum, SC, that had developed a significant frost crack. Mike Hall, the company’s owner, noted, “frost cracks are more than just a cosmetic issue; they can lead to increased susceptibility to pests and disease… and structural instability”. Because the crack compromised the tree’s structure, arborists removed it ahead of a forecasted ice storm to prevent a potential collapse.

Storm Damage Indicators

Winter storms bring more than just freezing temperatures – they bring winds and ice that can wreak havoc on trees. While winter freezes primarily damage leaves and bark, storms often cause immediate structural issues that demand urgent attention.

Ice and Wind Damage

Ice buildup is one of the most destructive forces trees face during winter storms. Freezing rain can coat branches, increasing their weight by as much as 30 times and causing them to snap under the strain. Trees like Southern magnolias, with their broad and heavy branches, are especially prone to breakage when ice accumulates.

High winds add another layer of danger. Sudden leaning or soil heaving near the base of a tree often signals that the root system has been compromised. If you notice soil lifting around the tree, it could mean the roots have lost their hold, increasing the likelihood of the tree toppling.

Crown damage is also a critical issue. When a significant portion of a tree’s crown breaks off, its ability to generate energy through photosynthesis is greatly reduced, which can severely impact its health.

Structural Problems

Storm winds don’t just break branches; they can twist and torque trees, leading to deep vertical cracks in the trunk. These cracks, caused by the intense mechanical stress of bending and twisting, are different from the splits caused by frost.

Pay close attention to branch unions, particularly those with narrow crotches. If you spot bark growing inside these joints – known as “included bark” – the union is more likely to fail during future storms.

Avoid trying to remove ice manually from trees. Frozen wood is brittle and may snap under pressure. Let the ice melt naturally; in many cases, branches bent under the weight will gradually return to their original position as the ice thaws.

Storm-damaged trees can collapse without warning, posing risks to both property and personal safety. If you observe any of these structural issues, keep people and vehicles at a safe distance and contact a professional for an assessment. Early detection and action are key to managing storm damage effectively.

How to Check if Your Tree is Still Alive

After assessing for visible frost or storm damage, it’s time to test whether your tree is still alive or just dormant. Winter can leave trees looking lifeless, but two simple methods can help you figure out if your tree is still kicking.

The Scratch Test

The scratch test is a quick way to see what’s happening beneath the surface. Grab a clean tool – like a fingernail, pocketknife, or pruners – and sterilize it with 70% isopropyl alcohol. Then, gently scrape away a small bit of bark on a young twig to expose the cambium layer underneath.

Take a close look at the cambium layer:

“The layer immediately under the bark should be moist and green”, explains Davey Tree.

If it’s bright, moist, and green, your tree is alive and growing. But if it’s brown, dry, or brittle, that branch is likely dead.

Don’t stop at just one branch – check several around the tree. Some limbs may have suffered winter dieback while the rest of the tree is fine. If you find green tissue further down a branch with a dead tip, prune back to a healthy node to help the tree recover. And remember, some trees – like certain oak species – are late bloomers and might not show signs of life until spring is well underway.

Checking Buds and Branch Movement

Dormant but healthy trees often have firm, well-attached buds that reveal a hint of green when gently pried open. On the other hand, dead buds are usually shriveled, dry, or fall off with a light touch.

You can also test small branches by bending them. Living branches are flexible and will spring back, while dead ones snap or crack easily, much like dry twigs. If you notice new shoots growing from the base of the tree, it’s a good sign the roots are still active. However, if the upper branches remain lifeless by late spring, take a closer look at the roots. Healthy roots are white or light-colored, while rotting ones appear brown and mushy. Keep in mind that Charleston’s humid climate and frequent storms can sometimes hide signs of internal decay.

What to Do About Winter Tree Damage

Once you’ve identified which branches are salvageable, it’s time to tackle the damage left behind by winter. Acting promptly and with care is key.

Pruning and Removing Damaged Branches

Hold off on pruning until late winter or early spring. This timing is important because it may take months for the full extent of the damage to become visible. New growth will help pinpoint where the dead wood ends. However, you should immediately remove “widow makers” – those precarious, hanging branches that pose a safety risk.

When pruning larger branches (over one inch in diameter), use the three-cut method. Start with an undercut 8–12 inches from the trunk, followed by a top cut to remove the branch’s weight. Finish with a clean cut just outside the branch collar – the slightly swollen area where the branch meets the trunk. This technique prevents bark from tearing and minimizes damage. Avoid cutting flush against the trunk or leaving long stubs, as both can lead to decay. Skip the wound paint or sealant; current arborist research shows these products trap moisture and slow the healing process.

For smaller twigs, sharp and disinfected bypass pruners work best, while loppers or a saw are better suited for larger branches. Always disinfect your tools between cuts using a 10% bleach solution or 70% isopropyl alcohol to prevent the spread of disease. Garden expert Carmen Johnston offers this advice:

“Wait until ice has melted and branches are no longer slick before inspecting plants… Prune with purpose, not emotion”.

Proper pruning not only ensures the health of your trees but also aids in their recovery. If the damage seems extensive or access is difficult, it’s wise to leave the job to professionals.

When to Call a Professional

If the damage is beyond what you can safely handle, it’s time to bring in a certified arborist. For trees taller than 20–25 feet or with trunk diameters over 8–10 inches, professional assistance is highly recommended. The same goes for trees with deep trunk splits, branches hanging precariously over your home, or those that have lost more than half their crown. Professional storm pruning typically costs between $200 and $800 per tree, depending on the size and complexity of the job. Trees that lose up to 50% of their crown often recover well with expert restorative pruning.

Conclusion: Protecting Your Trees After Winter

Taking the right steps to care for your trees after winter can make a big difference in their health and longevity. Start by inspecting your Charleston trees with a simple scratch test: gently scrape the bark to see if the tissue underneath is green and moist, which indicates the branch is still alive. If it’s brown or dry, that branch is likely dead. Also, look out for visible signs of damage like cracked bark, broken limbs, or missing buds – these are clear indicators that your trees may need attention. Waiting until late winter or early spring to prune is wise, as some damage might not show up immediately.

Quick action is key. Addressing issues early can save you money and help prevent pests or diseases from spreading, which could lead to expensive emergency tree removals later on.

As the seasons change, get your trees ready for hurricane season by scheduling structural pruning between May and early June. During dry spells, keep them hydrated, add 2–4 inches of mulch to retain moisture, and hold off on fertilizing until you see fresh spring growth.

If you notice significant trunk damage or other major issues, it’s time to bring in a certified arborist. Hernandez Trees & Lawn Care can help with trimming, removal, or stump grinding. Taking these steps now not only protects your trees but also ensures your property stays safe and visually appealing all year long.
