If you’ve ever wondered when to trim trees in Denver, you’re not alone. Timing matters more here
than almost anywhere else in the country. Denver’s semi-arid climate, with its dramatic temperature swings, late
spring freezes, scorching dry summers, and surprise early-fall snowstorms, creates conditions that can either
support healthy tree growth — or undo it — depending on when you pick up the pruning shears.
Trees in the Denver Metro area face unique stressors that don’t apply in more temperate regions. A mid-April
hard freeze can devastate freshly pruned trees. A July heat wave can turn an open pruning wound into an entry
point for insects and disease. Getting the timing right is one of the most important things a homeowner or
property manager can do for long-term tree health. This seasonal guide will walk you through exactly when — and
when not — to schedule tree trimming in Denver, broken down by season and by species.
