Storm Damage Tree Care: What Austin Homeowners Should Do First

Storm Damage Tree Care: What Austin Homeowners Should Do First

‍

Austin’s spring storm season can be brutal — high winds, hail, and heavy rain that arrive fast and leave real damage behind. A tree that looked structurally sound yesterday can have major split limbs, uprooted sections, or hanging branches today. The decisions you make in the hours and days after storm damage are critical — both for your safety and for whether a damaged tree can be saved. Here’s the right sequence.

‍

Your First Priority: Safety

‍

Don’t Walk Under Damaged Trees

‍

After any significant storm, stay away from damaged trees until a professional can assess them. Hanging branches — what arborists call “widow makers” — can fall without warning, even hours or days after a storm. They often appear to be wedged in place but are balanced precariously. Stay well clear of any tree with visible hanging branches or split limbs until they’ve been cleared by a professional.

‍

Check for Utility Line Contact

‍

If a tree or large branch has fallen across a power line or appears to be in contact with utility lines, do not approach it. Call Austin Energy’s outage line immediately and stay at a safe distance. Energized lines can arc to damp wood and soil — the ground around a downed line can be lethal even without visible contact.

‍

Assessing What Can Be Saved

‍

The 50 Percent Rule

‍

If a tree has lost less than 50% of its canopy, it has a reasonable chance of recovery with proper care. Trees are remarkably resilient and can often regrow substantial canopy over two to three growing seasons after storm damage. The critical variables are the species, the tree’s overall health before the storm, the type of damage, and whether major scaffold branches remain intact.

‍

When Removal Is the Right Call

‍

Some storm damage is simply too severe to recover from. Trees with split trunks, major structural failure at the root zone, or loss of more than half the canopy are usually better removed than maintained as declining, increasingly hazardous specimens. A certified arborist can give you an honest assessment — and a good arborist will tell you when saving a tree doesn’t make sense, not just when it does.

‍

Immediate Care for Damaged Trees

‍

Remove Hanging Branches First

‍

The first priority for any salvageable damaged tree is removing all hanging and broken branches. These provide no benefit to the tree, create ongoing wound surfaces that invite decay and disease, and remain safety hazards. Once broken branches are removed, a certified arborist can evaluate remaining structure and recommend a pruning plan to rebalance the canopy.

‍

Do Not Apply Wound Sealants

‍

Contrary to old conventional wisdom, applying tar or wound sealant to storm damage cuts does not help trees heal and may trap moisture and pathogens against the wound. Modern arboricultural research shows that trees form their own protective callus tissue and seal wounds most effectively when left exposed to air. Make clean cuts where practical and let the tree handle the rest.

‍

Support with Follow-Up Care

‍

Structurally stressed trees benefit from deep root watering and fertilization after major storm events. Losing significant canopy is physiologically stressful, and supporting the root system helps fuel the recovery growth the tree needs. If the storm occurred during oak wilt transmission season (February through June), seal any fresh cuts on oaks immediately and consult an arborist before additional pruning. Agave Tree Services provides emergency storm response across Austin and the surrounding area — reach out after any significant event for a fast, honest assessment.
