Spring Yard Cleanup Checklist for Missoula & the Bitterroot Valley

When should you start spring cleanup in the Bitterroot Valley?

Start once the snow has fully melted and the soil is no longer soggy, usually late March into April in zone 4 to 5. Working frozen or waterlogged ground compacts the soil and damages dormant grass crowns. Wait until you can walk the lawn without leaving deep footprints, then begin with the lightest tasks first.

Because elevation varies across Ravalli County, properties up the canyons thaw later than those on the valley floor. Let your own yard set the pace rather than the calendar, and check that overnight lows have mostly stayed above hard freezes before pruning or planting.

How do you assess winter and snowmelt damage on trees?

Walk your property and look for broken, cracked, or hanging limbs left behind by snow load and wind. Ponderosa pine, Douglas fir, aspen, and cottonwood can all carry hidden cracks after a heavy Montana winter. Note any branches over the house, driveway, or power lines, and any leaning trunks or lifted root plates near the soil.

Remove small, clearly dead wood yourself, but leave large, high, or tension-loaded limbs to a professional. An ISA-certified arborist can spot internal decay and storm cracks that are easy to miss from the ground, and make proper cuts that help the tree seal and recover.

What should you do for your lawn and garden beds?

Rake out matted leaves, fallen needles, and dead thatch so air and light reach the crowns, which helps grass green up faster. Clear winter debris, gravel thrown by plows, and any snow mold patches, then lightly cultivate compacted areas. Hold off on heavy fertilizing until the lawn is actively growing.

In beds, cut back dead perennial stems, pull early weeds before they seed, and refresh mulch to two or three inches to hold moisture through the coming dry summer. Keep mulch pulled back a few inches from trunks and crowns to prevent rot and discourage voles.

When is the right time to prune in early spring?

Prune most shade and evergreen trees in late winter to early spring while they are still dormant, before bud break. Dormant pruning reduces stress, improves structure, and lowers disease risk. Remove dead, damaged, and crossing branches first, and avoid heavy cuts on spring-flowering shrubs until after they bloom.

Avoid topping trees or making large flush cuts, which create weak regrowth and decay. If a tree needs significant shaping or has storm wounds, a trained crew can prune for long-term health and safety rather than just appearance.

How do you safely start up your irrigation system?

Wait until the danger of a hard freeze has passed, then slowly recharge the system to avoid water-hammer damage to lines and valves. Open the main valve gradually, then walk each zone to check for leaks, broken heads, and lines damaged by frost heave or rodents over winter.

Adjust spray patterns so water lands on plants rather than pavement, and set early-season run times short while temperatures are still cool. Catching a cracked head or leaking valve now saves water and prevents bigger failures during the hot months ahead.

What spring tasks are best left to a professional?

Leave large-limb removal, tree-health assessments, and irrigation repairs to a licensed, insured crew with the right equipment. These jobs carry real risk near power lines, ladders, and pressurized water, and small mistakes can be costly. A professional visit early in the season also catches problems before summer stress sets in.
