After every major Houston storm, we end up with a similar mix of fallen trees. Twelve years of post-storm work shows clear patterns — some species fail repeatedly, others rarely. Knowing which is which can shape preventive choices.
1. Loblolly pine — the #1 storm faller
Pines are the most common windthrow species in Houston metro. They're tall (often 80–100+ ft), they have shallow root systems, and they don't bend much before they break or uproot.
Failure modes:
- Whole-tree uprooting in saturated soil during sustained high winds
- Trunk snap mid-tree, especially in trees with previous defects
- Lateral branch failure on imbalanced crowns
Prevention: Wind-sail reduction every 2–3 years on pines over 60 ft near structures.
2. Bradford pear (Callery pear)
The fastest-growing common Houston tree is also the weakest. Bradford pears have notoriously weak branch architecture — V-shaped crotches with bark inclusion that split on the most basic wind events. Trees over 15 years old often fail without any storm at all.
Recommendation: Remove and replace. Almost no Bradford pear is worth keeping past 15 years.
3. Sweet gum
Sweet gums grow fast and tall — often outpacing their structural strength. Heart rot is common in older sweet gums, and storms exploit any internal decay.
Failure modes:
- Trunk failure at decay sites
- Major branch breaks during sustained winds
Prevention: Annual crown cleaning to remove deadwood; consider removal of decline-stage trees before they fall.
4. Mulberry
Brittle wood, surface roots, and aggressive growth make mulberries common storm casualties. They're also rarely worth saving — invasive tendencies, messy fruit, and short lifespan.
5. Pecan
Surprising on the list, but pecans have brittle wood compared to oaks. Heavy nut crops in fall can stress branches that then fail in winter or spring storms. Major lateral branches are most prone to failure.
Prevention: Selective lateral pruning to balance the crown, especially after heavy nut years.
The trees that handle storms well
- Live oak — flexible branches, dense wood, strong root systems. Rare failures in healthy specimens.
- Bald cypress — flexible, deeply rooted, handles wet soil well
- Cedar elm — drought-adapted with strong wood
- Magnolia — slow-growing, dense wood, low to medium failure rate
Failure factors beyond species
- Saturated soil: Even strong-rooted species fail in waterlogged ground
- Previous defects: Cavities, decay, co-dominant trunks
- Untouched canopy: Trees with no recent pruning work catch more wind
- Construction nearby: Compaction or root damage that may not show until 3–5 years later
- Sudden exposure: Trees that grew up in a sheltered cluster suddenly exposed when neighbors removed adjacent trees
What we saw after Beryl (2024)
Hurricane Beryl was a Cat 1 — far from Houston's worst storm. But it took out a striking number of trees because of saturated soil leading up to landfall. Pines and Bradford pears fell in roughly the proportions you'd expect; live oaks held in surprisingly tough shape; sweet gums showed more failures than usual.
The common factor across Beryl failures: trees that hadn't been touched in 5+ years.
Action items for Houston homeowners
- Inventory your trees by species and approximate age
- Schedule wind-sail reduction for pines over 60 ft near structures
- Plan removal-and-replacement for any Bradford pears
- Get sweet gums and mulberries assessed before each hurricane season
- Don't ignore live oaks — even tough trees need maintenance
Pre-hurricane assessments are free and we can usually do them within a week. (281) 626-9111 or book online.
