The Utah Yard Maintenance Calendar

A printable month-by-month rhythm for Wasatch Front yards — pruning, irrigation start-up, winterizing, and more.

9 min read · Updated June 25, 2026

A Utah yard runs on a rhythm: wake the irrigation up in spring, mow high and water deep through the heat, feed and plant in fall, then shut it all down before the freeze. Miss the beats — an early sprinkler start, a forgotten blow-out — and you pay for it in water bills or cracked fittings. Here's the whole year on one page, built for the Wasatch Front.

Late Apr–May

Spring irrigation start-up

~3 in

Mow lawns tall through summer

Fall

Best time to fertilize cool-season lawn

Mid–late Oct

Blow out before the first freeze

The Utah yard year

The calendar below groups the tasks that actually move the needle — irrigation, mowing, fertilizing, planting windows, pruning, and winterizing — by month. Treat it as a printable checklist and shift the edges a couple weeks later if you're on a bench or at higher elevation.

Valley-floor Wasatch Front timing; benches and higher elevations run a week or two behind in spring.
Month	Key tasks
January	Dormant season. Plan the year, sharpen and service mower blades, knock heavy snow off shrubs. No watering.
February	Begin dormant pruning of deciduous shade and ornamental trees while structure is visible and the tree isn't stressed.
March	Finish dormant pruning. Clean beds, edge, and refresh mulch to ~3 in. Apply pre-emergent if you target weeds. Soil often still too wet to work.
April	Cool-season planting and overseeding; light spring lawn feed after green-up. Hold irrigation start-up until plants actually need water.
May	Last frost passes early-to-mid month — set out warm-season plants after it. Start and inspect the irrigation system; fix winter-damaged heads and emitters.
June	Switch to deep, infrequent watering; raise mowing height to ~3 in. Mulch beds before peak heat to cut evaporation.
July	Peak heat: water deep and infrequent, early morning. Don't fertilize lawns heavily now. Deadhead and shear perennials for rebloom.
August	Maintain deep watering; watch for heat and chlorosis stress. Late August is a good window to start fall cool-season seed.
September	Prime planting month for trees and shrubs. Fall lawn fertilizing (the most valuable feeding). Overseed thin fescue/bluegrass lawns.
October	Plant trees until the ground freezes and spring bulbs. First frost mid-month. Blow out and winterize irrigation before the first hard freeze.
November	Final leaf cleanup, mow lawn a touch shorter for the last cut, deep-water evergreens before the ground freezes. Drain and store hoses.
December	Dormant season. Protect young/thin-bark trees from sunscald and rodents, brush snow off evergreens. Plan next year.

Watering and mowing through the heat

Don't miss the two irrigation dates

Two irrigation tasks bracket the season and cause the most expensive mistakes when skipped: the spring start-up walk (late April–May, to catch winter-damaged heads and emitters before plants stress) and the fall blow-out (mid-to-late October, before the first hard freeze, to keep ice from cracking lines). Our drip irrigation basics guide covers both in detail.

Keep planting on the same calendar

Maintenance and planting share the same seasons here — fall is both the best time to fertilize a cool-season lawn and the best window to plant trees. Run this maintenance rhythm alongside the Utah planting calendar so the two never work against each other.

Utah yard maintenance FAQ

When should I turn my sprinklers on in spring in Utah?

Hold off until the lawn and plants actually need it — usually not until late April or May, once the soil has dried and warmed and natural moisture tapers off. Turning irrigation on too early wastes water and encourages shallow roots. When you do start, walk every zone to check for emitters and heads that failed over winter before you rely on the schedule.

How high should I mow my lawn in Utah?

Mow cool-season lawns (Kentucky bluegrass, fescue) on the tall side — around 3 inches, never scalped. Taller grass shades the soil, cuts evaporation, and grows deeper roots, all of which matter a lot in our dry summers. Follow the one-third rule: never remove more than a third of the blade in a single mow, and leave the clippings to feed the lawn.

When do I fertilize my lawn in Utah?

For cool-season Utah lawns, the most valuable feeding is in fall, which builds roots for winter and an early green-up. A light spring feeding after green-up is fine, but avoid heavy nitrogen in the heat of summer, which stresses the lawn and pushes weak growth. Always water fertilizer in.

When should I blow out my sprinkler system in Utah?

Before the first hard freeze — typically mid-to-late October on the Wasatch Front. Water left in lines, valves, and drip emitters freezes, expands, and cracks them. Blow out the lines with compressed air at safe pressure and drain the backflow preventer. Don't gamble on a late warm fall; an early freeze is what does the damage.

When is the best time to prune trees in Utah?

For most deciduous shade and ornamental trees, prune in late winter while they're dormant (roughly February into early March) — the structure is visible, the tree isn't stressed, and there's no foliage in the way. Avoid heavy pruning in fall. Spring-flowering shrubs are the exception: prune them right after they bloom so you don't cut off next year's flowers.
