In San Antonio, when you do tree work matters almost as much as what you do. Prune an oak at the wrong time and you risk oak wilt; wait until May to think about storm-season pruning and you'll be at the back of a long line. Here's a season-by-season calendar to keep your trees healthy, safe, and on schedule.
Key Takeaways
- Winter (Dec–Feb): prime window for oak pruning, removals, and cedar clearing.
- Spring (Mar–May): storm season and the oak-wilt no-prune window — book early, avoid oak cuts.
- Summer (Jun–Aug): deep watering and light work only; assess drought and disease.
- Fall (Sep–Nov): fertilize, plant, resume oak work, and book winter clearing before the rush.
Winter (December–February): The Prime Window
Winter is the best time for most major tree work in San Antonio. Deciduous trees are dormant, structure is easy to see with the leaves down, and — most importantly — it's the safe window to prune oaks, when oak-wilt beetles are least active (always paint the wounds anyway). This is the season for structural pruning, removals, and cedar clearing across the Hill Country.
- Prune oaks: Safest oak-pruning window; always paint wounds.
- Cedar clearing: Peak season for Ashe juniper removal and lot clearing.
- Removals & big work: Bare canopies make major work easier and safer.
Spring (March–May): Growth, Storms & Restraint on Oaks
Spring is when trees leaf out — and when San Antonio's severe weather peaks with hail and wind. It's also the heart of the oak-wilt risk window (remember: no unnecessary oak pruning February 1–July 1). Focus spring on non-oak pruning, storm cleanup, and health care for stressed trees. And book early: May is our busiest month, and the calendar fills before the first big storm.
Summer (June–August): Survive the Heat
San Antonio summers are brutal on trees, especially the drought-stressed live oaks on shallow soil in areas like Stone Oak. Summer is about keeping trees alive: deep, occasional watering, proper mulching, and light pruning only. Avoid heavy pruning in extreme heat — it stresses trees further. This is a good time for health assessments to catch drought and disease decline before it becomes a hazard.
Fall (September–November): Recover & Prepare
As the heat breaks, trees recover and it's an excellent time to set them up for the year ahead. Fall is ideal for deep-root fertilization, planting new trees, and — once we're safely past the oak-wilt peak — resuming oak work. It's also the smart time to book winter cedar clearing and get on the schedule before the rush.
Why May Books Out First
Every year it's the same: homeowners wait until spring storms are rolling in to call about that limb over the roof, and by May every good crew is slammed. The trees that get handled calmly and affordably are the ones scheduled in fall and winter. If you know a tree needs work, the cheapest, least-stressful time to deal with it is months before storm season — not the week it fails.
