Spring Yard Cleanup Checklist for Wisconsin Yards

Start spring cleanup when the ground is firm and dry, then work in this order: clear debris, rake matted grass lightly, check for plow and salt damage, cut back beds, prune, edge, mulch, and mow last. RAH Solutions LLC, a family-owned landscaper in Edgerton, recommends this sequence for every yard.

The order matters because each step sets up the next one. Debris has to come off before you can see winter damage, beds have to be cut back and edged before mulch goes down, and the lawn has to be growing before a mower belongs on it. Rushing the early steps on wet ground does more harm than a late start.

When is it safe to start spring cleanup in Wisconsin?

It is safe once the soil has thawed and dried enough to walk on without leaving footprints. RAH Solutions advises going by ground conditions, not by a date on the calendar.

UW–Madison Extension puts it plainly: lawns need to thaw out and dry out, and it is best to stay off them until they do. Many yards in Rock and Dane counties sit on silt loam over a heavier subsoil that drains slowly, so they stay soft well after the snow is gone. Foot traffic, wheelbarrows and equipment on saturated ground press the soil tight and leave ruts that last all season. Driveways, walks and raised beds can be cleaned up first while the lawn dries.

What is the right order for a spring yard cleanup?

Work from the ground up and from cleanup to finish: debris, lawn, damage check, beds, shrubs, edges, mulch, mowing. RAH Solutions recommends this ten-step sequence for southern Wisconsin yards.

1. Wait for firm ground. No footprints, no standing water.
2. Pick up sticks and debris. Branches, leftover leaves, litter and gravel thrown by plows.
3. Rake matted turf gently. Lift flattened, straw-colored patches so air reaches the crowns.
4. Inspect for plow and salt damage along drives, walks and the street.
5. Cut back perennials and ornamental grasses left standing over winter.
6. Prune summer-flowering shrubs. Leave spring bloomers alone until after they flower.
7. Edge and clean the beds. Pull early weeds and re-cut the bed line.
8. Hold the mulch until the soil has warmed and perennials are up.
9. Mow at normal height once the grass is actively growing.
10. Save seeding for late summer unless you have bare soil.

How do you fix snow mold, plow damage and salt damage on a lawn?

Most winter lawn damage needs a light raking, some patience and a little seed on the worst spots. RAH Solutions suggests checking four things once the debris is off.

• Snow mold. UW–Madison Extension describes it as roughly circular patches of bleached or straw-colored, matted grass. Lightly rake the patches to help them recover. Reseed only the ones that do not green up.
• Vole trails. Winding paths and small piles of grass show up where snow sat for a long time. Rake them out and the surrounding turf usually fills in.
• Plow damage. Sod peeled back along a driveway can be pressed back down if it is caught early. Gouged edges need topsoil and seed.
• Salt damage. Brown strips along walks and the street are often salt injury. UW–Madison Extension advises watering the soil heavily in early spring to flush salt out of the root zone.

Use a leaf rake, not a metal garden rake or a power rake. University of Illinois Extension gives the same advice for early spring, because grass loosened by freeze–thaw cycles pulls out easily. A thick mat of leaves left on the lawn since autumn smothers turf and encourages snow mold, which is one reason a fall yard cleanup pays off in April.

What should you cut back and prune in spring?

Cut back last year’s perennial stems and ornamental grasses before new growth gets tall, and prune only the shrubs that bloom in summer. RAH Solutions suggests doing beds after the lawn is cleared so debris is only hauled once.

Ornamental grasses are easiest to cut when they are bundled first and trimmed before growth resumes. Work by hand around hostas and other perennials whose new buds sit just under the surface.

For shrubs, timing follows bloom. UW–Madison Extension’s pruning guide says summer-flowering shrubs such as hydrangea, Japanese spirea and potentilla are pruned while dormant or in early spring before the buds break. Spring-flowering shrubs such as lilac, forsythia and viburnum are pruned after they flower, because their buds formed last year. Prune a lilac in April and you cut off this year’s flowers. Dead and broken branches can come off any shrub at any time. Shrub trimming covers the shaping that follows.

What spring jobs should wait?

Mulch, the first mow and most seeding should wait for warmer soil and growing grass. RAH Solutions advises holding these three back even when the rest of the cleanup is finished.

Mulch. Mulch laid on cold soil keeps it cold. Iowa State University Extension advises waiting until the ground warms and perennials emerge. In this area that usually means mid to late spring. The guide to how much mulch you need has the math for ordering.

Mowing. Mow when the grass is growing, at the normal height of about 3 inches. UW–Madison Extension warns against making the first cut excessively short, and the one-third rule applies from the first mow. Regular lawn maintenance starts here.

Seeding. Bare soil should be seeded in spring, in late April to early May, before weeds move in. A lawn that is only thin is better left for late summer, as the aeration and overseeding guide explains.
