Hurricane Season Tree Prep: A Houston Homeowner’s Checklist

Why Houston trees fail in storms

The Atlantic hurricane season runs from June 1 through November 30, and Houston does not need a hurricane to lose trees: the May 16, 2024 derecho knocked out power to more than 900,000 customers weeks before Beryl arrived. Between the two storms the region hauled away an estimated 4.5 million cubic yards of debris, most of it wood.

Trees fail for predictable reasons. Saturated clay soil loses its grip on root plates, so whole trees tip over. Decay hidden in trunks and major unions lets limbs tear out. Dense, unpruned crowns act as sails. And some species simply were not built for it: water oaks and laurel oaks are short-lived trees that are often hollow by 60 or 70 years old, which is roughly the age of the ones planted when many Houston neighborhoods were built.

Pre-season checklist (do this by late spring)

1. Walk the property and look for warning signs

• Dead limbs larger than two inches, especially over roofs, driveways and sidewalks.
• Cracks, splits or seams in the trunk or where large limbs meet it. Two trunks of similar size joined in a tight “V” (included bark) are a classic failure point.
• Cavities, soft spots, carpenter ants or mushrooms and shelf fungi at the base or on the trunk. Fungus on the outside means decay on the inside.
• A new lean, soil heaving or cracking on one side of the base, or exposed roots that were buried last year.
• Dieback at the top of the crown, thinning foliage, or a canopy that leafed out late this spring.
• Construction in the last few years within the drip line: trenching, grade changes, new driveways. Root damage shows up as storm failure two to five years later.

2. Prune for wind, not for looks

Good storm pruning removes deadwood, reduces over-extended limbs back to strong lateral branches, raises clearance over the roof, and thins crowded areas so wind can move through. It leaves the interior structure alone. Avoid anyone who proposes topping, stripping interior growth (lion-tailing) or taking off more than about a quarter of the live canopy, because all three make trees weaker.

Timing: pines, pecans, elms, magnolias, crape myrtles and most other species can be pruned in spring. Oaks should be done in December and January, or in July and August with wounds painted, to avoid oak wilt. See when to trim oak trees in Houston.

3. Decide on the trees you have been putting off

A dead or dying tree within falling distance of the house is the one item on this list that is not optional. The cost of a scheduled removal in April is a fraction of an emergency removal off a roof in August. If a large tree with structural problems is worth keeping, cabling and bracing can reinforce weak unions, but that is a decision for an on-site assessment.

4. Respect the power lines

CenterPoint Energy trims and removes trees that threaten its primary lines through its forestry program and asks residents not to trim within 10 feet of a line. If limbs are in the main lines along the street or alley, call CenterPoint’s forestry team at 713-207-2222. A tree crew can work around the smaller service drop to your house, but they will plan the job around it.

5. Document everything

Photograph every large tree from two angles with the house in frame, and date the photos. If a tree later damages the house, these pictures support the claim. Keep your tree company’s invoices; they show you maintained the trees, which matters if a neighbor’s property is damaged.

6. Know the plan before the storm

Save the numbers you will need: your insurer’s claims line, CenterPoint outages (800-332-7143), and a tree company that actually answers at night. Clear the yard of loose items that become projectiles. If a storm is forecast, do not start last-minute pruning the day before; half-finished work and stacked brush make things worse.

After the storm

1. Treat every downed line as live. Stay back, keep others back, and report it. Do not touch a tree, fence or puddle that is in contact with a line.
2. Do not cut anything under tension. A tree resting on a roof, fence or another tree stores enormous energy. This is where chainsaw injuries happen after every Houston storm. Leave it for a crew with rigging.
3. Photograph before cleanup. The tree, the damage, the yard. Then call your insurer and get a claim number.
4. Prioritize access and safety. Clear the driveway and the path to the door, then the roof, then the rest. Trees that are down in the yard and not touching anything can wait a week; prices are better after the first rush.
5. Vet the crew. After Beryl, Houston saw out-of-town crews knocking on doors. Ask for a certificate of insurance showing general liability and workers’ compensation, get the scope in writing, and pay when the job is finished and you have walked the yard. Never pay a large cash deposit.
6. Check the survivors. Trees that stayed up can still be damaged: cracked limbs that have not fallen yet, root plates lifted an inch, limbs hung up in the canopy. A post-storm assessment catches the second wave of failures.

Species notes for Houston yards

Frequently asked questions

When should I have my trees trimmed before hurricane season in Houston?

Late winter is ideal for most species, before the June 1 start of the Atlantic season. The exception is oaks: avoid pruning them from February through June because of oak wilt, so schedule oak work for December–January and, if needed, a light pass in July with every cut painted.

Which trees are most likely to fall in a Houston hurricane?

Water oaks and laurel oaks (short-lived, often hollow when mature), tall pines with thin canopies or beetle damage, Bradford pears, and any tree with a lean, a cavity, mushrooms at the base, or roots lifted on one side. Healthy, properly pruned live oaks generally hold up well.

Does trimming really reduce storm damage?

Yes, when it is done right. Removing deadwood, reducing over-extended limbs and thinning dense crowns lets wind pass through instead of pushing the whole tree over. Over-thinning, topping and lion-tailing do the opposite and make failures more likely.

Who removes a tree that falls on power lines?

Stay away from it and assume every line is live. Report it to CenterPoint Energy. The utility or its contractors clear trees on their lines; a tree crew handles the rest once the lines are de-energized or cleared.

Will insurance pay to remove a tree that fell in my yard?

Usually only if it damaged a covered structure, and often with a per-tree or per-storm limit for debris removal. Photograph the tree, the damage and the surrounding area before any cleanup, keep receipts, and ask your adjuster how the debris-removal benefit works.
