Spring in a Westchester yard: what to do and when to do it

A Westchester winter works on a yard three ways. Freeze-thaw moves things: stones heave, walk edges lift, wall faces open a joint. Plows and salt burn the lawn along the road and the driveway. And months of snow load flatten turf and snap the weak wood out of trees and shrubs.

So the first spring job is a slow walk, not a rake. Check the lawn edges along pavement for salt burn. Look for matted gray patches of snow mold where drifts sat. Look at every wall, step and walkway edge and ask whether it moved over the winter. A stone that lifted half an inch is a spring reset; the same stone ignored becomes a summer trip hazard and a fall repair.

The biggest March mistake in this county is working soil that is still saturated. Step on the lawn: if the footprint stays, every pass with a mower or wheelbarrow is compacting soil and tearing turf that cannot recover yet.

What March is actually for: cutting back the perennials left standing over winter, pruning out winter-killed wood, picking up branch drop, and planning. Summer-blooming shrubs can be pruned now; spring bloomers like forsythia and lilac get pruned after they flower or you are cutting the flowers off.

March is also when the season books. By the time the ground is workable, spring schedules across the county are largely spoken for.

Once the footprint test passes, the real cleanup runs: beds cleared, edges recut, the first mow. Take that first cut a notch lower than summer height to clear the winter mat, then bring the deck back up.

Timing pre-emergent weed control is a soil thermometer job, not a calendar job. Crabgrass germinates as soil holds the low 50s. The county's forsythia is the folk indicator, and it is roughly right: full bloom means the window is open and closing.

April is also the month to fix the lawn's winter damage. Salt-burned road edges and plow gouges get topsoil and seed while the soil is cool and wet. Where a whole area failed, this is the fork: seed now and protect it from crabgrass season with committed watering, or hold larger renovations for early fall when nothing fights the new grass. Sod escapes the timing argument, which is why our sod work runs hard in spring.

Frost risk in northern Westchester runs to about mid-May, and the nurseries know it. Trees, shrubs and hardy perennials can go in earlier; tender annuals and vegetables wait for the soil to warm regardless of one warm week in April.

Mulch goes down after the soil has warmed, not before. Two to three inches, pulled back off trunks and stems. The mulch volcano piled against a tree trunk is the county's most reliably repeated mistake and it rots bark, invites rodents and kills trees slowly.

Plant with the deer in mind. North of the parkways especially, unprotected hostas and arborvitae at the woods line are a browse buffet. There are plants that hold and plants that need protecting, and any honest planting plan says which is which.

Melt season is the one time of year you can watch where water actually goes on a property. The fixes live on our drainage page; the watching costs nothing.
