S'no Fun Getting Rid of the White Stuff

This has been a bitterly cold winter though, until now, not especially snowy.  That appears to be changing.  We had eight inches of snow over the weekend, an inch yesterday morning, and there is a prediction for a 'major storm' for Thursday and Friday.  The problem for us is, what do you do when there's too much snow?

Planning for snow removal is part of
planning for a New England garden
This weather report is part of a garden blog because snow is a reality in New England and where to put snow is a continuing problem for any serious gardener in this region. Our particular issues are twofold: first, where the town puts the snow from the street and, second, where we put the snow from our driveway.

We are at the end of a cul-de-sac with a broad turning circle as part of our streetscape. The upside is that this gives us a very dramatic arc around which to design a garden. The downside is that the town plows have to put the snow from the other end of the street somewhere, and that ‘somewhere’ includes the buffer zone between our sidewalk and the street. And, because the town lays down chemicals to keep the street passable prior to plowing, the snow that ends up on that buffer zone (variously called an ‘easement’ or a ‘hell strip’) is laden with salts that render the strip inhospitable to grass.

This xeric bed - shown in its
summer glory - was under
several feet of chemical-
laden snow today
We’ve adapted the strip – some 960 square feet – into a xeric garden that is planted with perennials that tolerate the chemical soup. That garden planting scheme was detailed in this blog entry. There is already a two-foot-high mound of snow on part of that xeric garden and the Valentine's Day Storm could add several feet to that total.

The second issue is where we put the snow from our own driveway. We are set back 220 feet from the street on a meandering driveway and, at the head of the driveway, the asphalt widens out to 35 feet to feed a three-car garage, plus provide an additional backing-out area for cars. The home’s architect was apparently from some southern clime because the driveway dead-ends into the garage.  As such, there is no ‘simple’ place to put snow.  The problem grows geometrically with the depth of the snow and new snowfalls follow ones already on the ground.  There is already a four-foot-high wall of snow on one wall of the backing-out area.  After this storm, it may be double that height.

Removing 18 inches of snow - carefully
We’ve adapted the gardens along the driveway to this reality. (Double-click on the plot plan at the top of this post to get a more detailed view of the descriptions that follow.)  Along the main stretch of access, there is a grass strip roughly eight to ten feet wide, the sole purpose of which is to provide a landing spot for the snow from the driveway.  The driveway is never treated, so the snow simply provides moisture for the spring growing season.

This burlap skirt for
Thuja occidentalis was
added in November
The gardens in front of the house adjacent to the wide part of the driveway are, with a few exceptions, spring and summer perennials. A thuja occidentalis has a protective burlap skirt to deflect snow and we carefully direct our snowblower away from a now-seven-year-old oxydendrum that occupies the center of that bed. The perennials in the bed are already under a blanket of up to three feet of snow.  Absent a prolonged thaw, this area may not be bare until mid-March.

The wisteria bed was planned to
support heavy snow cover
in winter
Three years ago, we created a new garden at a critical area for snow removal. The "wisteria" garden, about which I wrote in 2010, is roughly 200 square feet and is anchored by six woody shrubs – three ilex and three miniature kalmia. The balance of the bed is spring- and summer-blooming perennials that can take heavy snow cover. After the blizzard, the depth of snow thrown in this area is up to five feet and is heavily compacted. We made every effort to direct snow around the tender kalmias. We cross our fingers each season and, so far, the kalmias have bounced back without damage.

The back of the turnaround area has long been planted with Kirengeshoma (Japanese wax bells) and Hakonechola macra ‘Aureola’ (Golden Japanese forest grass), with miscellaneous rhododendron behind them. These perennials die back to the ground in late September; the several feet of snow that cover the area all winter seems to make the plants thrive in the growing season.
