The damage shows at melt. The work happened under the snow.
We walk Silverthorne and Dillon foundations in April and find bark stripped in a neat line along the house. That is vole work under the snowpack, not a summer insect. The run is the warm, mulched strip against the foundation where snow sits for months and the soil never fully freezes the way the open lawn does.
If we wait until you see the girdle, the shrub is often already a stump with green on top. Plant health care after the fact is a removal and a replant, not a product that grows bark back. The time to change the habitat is this fall, before the snow bridges from the eave to the junipers.
A Silverthorne townhome with a north foundation and a Breckenridge cabin with a woodpile against the wall are both vole hotels. The woodpile is worse. We will say so.
Mulch, drip, and a tight shrub mass make the runway
Deep bark against siding holds cover. Drip that keeps that strip moist into October keeps the soil workable for tunnels. A solid mass of cotoneaster or juniper with no gap is a highway. We want a clean inspection strip along the foundation, not a planted-to-the-siding look.
Irrigation shut-down on that strip should happen when nights are cold, not when the rest of the lot still needs water. A wet foundation band in November is a vole gift. Lawn care that lets grass grow long against the wall does the same thing. We will edge that band as a winter prep item, not as a July aesthetic.
Maintenance can pull the woodpile off the wall, thin the shrub mass, and drop the mulch depth at the stem. Those are not extras. They are why two properties on the same street have different vole years.
Do not dump snow removal piles onto that same foundation band. A dirty pile against the shrubs is cover plus moisture. Stack on the drive edge or a sacrificial corner we agree on.
Traps, habitat, and a replant are three different scopes
Habitat first. If the runway stays, trapping is a winter hobby. If the shrubs are already girdled, we tag them now so spring is not a surprise. Replanting with the same species in the same mulch strip is how we repeat the bill.
Cats and “natural control” stories do not replace a gap at the siding. We still see runs on lots with dogs. The snow is the cover.
Design for a new bed along a Silverthorne foundation should leave a stone or gravel band the voles do not love and a crew can inspect. Construction of that band is cheaper than replacing a hedge of burned junipers.
The garden nursery can source replacements that are less of a buffet if we are already ripping dead plants. That is a spring decision with this fall’s photos in the file.
Photograph the foundation line before the snow bridges
Before winter, we want a dated photo of the foundation strip, mulch depth, and any existing chew. After melt, we photograph the same line. New girdles in the same frame are a habitat miss, not bad luck.
Call 970-468-0340 or contact us with town and a photo of the north wall planting. Related notes live on the blog. We would rather move mulch in September than write off a hedge in May.
