The Best Time to Trim Trees in Fresno & the Central Valley

"When should I trim my trees?" is the question we get more than any other in Fresno. The short answer: most trees in the Central Valley are best pruned in late winter to early spring, while they're dormant — but it genuinely depends on the species and your goal. Here's the local breakdown.

Why Timing Matters in the Central Valley

Our valley climate is hard on trees: blazing summers, mild wet winters, and the spring windstorms that snap weak limbs. Pruning at the right time keeps trees strong going into that wind and heat, helps them heal faster, and avoids inviting disease or sunburn on freshly exposed bark.

The General Rule: Prune in Dormancy

For most shade and ornamental trees, December through early March is the sweet spot. The tree is dormant, its structure is easy to see with the leaves off, cuts heal quickly as spring growth starts, and you're not stressing the tree during summer heat.

Timing by Tree Type

Fruit trees

Prune in winter dormancy (January–February) to shape and encourage fruit. Some stone fruits also get a light summer prune right after harvest — but the big structural cuts belong in winter.

Oaks

Prune California oaks in the dry dormant months and avoid the wet spring — pruning wounds in damp weather raise the risk of disease. Late fall through winter is ideal.

Ash, liquidambar & other shade trees

Classic dormant-season candidates. Late winter thinning improves airflow and removes deadwood before the spring winds test the canopy.

Crape myrtle

Late winter, before the spring flush. Prune for shape — and please, no "crape murder" (topping it to stubs); it ruins the form and the bloom.

Palms

Palms are the exception — trim them in late spring to early summer, after the fruit stalks emerge. Only remove fully dead, brown fronds; over-trimming green fronds ("hurricane cutting") weakens the palm.

When to Prune Regardless of Season

• Dead, broken, or hanging limbs — anytime, for safety.
• Limbs touching the roof, blocking a driveway, or growing into power lines.
• Storm damage — call us right away, day or night.
• Anything clearly diseased or hazardous.
