Februa


Calendar illustration for February, from a circa 1500 Dutch manuscript.

With the turn of a calendar page, we find ourselves in our shortest month, one which derives its name from the Roman feast of purification, Februa.

In the vineyard, February remains a time of cleaning, of preparation.

February is the month when most of our vineyard pruning takes place, a brief midwinter lull to prepare the vines for the flush of luscious growth that will drive our labors from bud burst through harvest.

Crunching through snowy vineyard rows, cutting away last year's ripened canes, we take comfort knowing that we are following the rituals of an ancient calendar.

Medieval prayer books and calendars frequently had illustrations depicting appropriate seasonal agricultural tasks for each month.

For Februa's month, more often than not, the calendar scenes depict ruddy-faced laborers gathering wood, warming themselves by a fire, or, out in a vineyard, cutting vines.

The sturdy vinedressers in the Medieval calendar illustration above also provide an answer to perhaps the most common question those of us who work in a vineyard still get asked today: what do you do in the winter?

The rows of vines, the tools employed, the layers of clothing: immediately recognizable to anyone who's worked a vineyard in February, despite the passage of so much time.

If winter vineyard work remains remarkably consistent, February itself is ever changing.

Some winters, our February fields look remarkably similar to the Dutch scene above: grass a dull green, the soil soft and friable. (Although our vineyard rows are tilled with a restored 1953 Farmall tractor, not the sturdy Dutch ox depicted.)

This winter and last, cold has prevailed in Canton, Ohio.

February's earth remains frozen solid, the tracks of deer and muskrats etched into icy ruts of wintry perambulations.

A mantle of snow has cloaked the vineyard since mid January, doing exactly what we want it to do: regulating the ground temperature, insulating the vines.

A persistent blanket of snow warms the North Vineyard.
One of our vineyard thermometer probes fell from the trellis wire into a snowbank on January 17th: ever since, it has recorded a temperature range of between 32.043 and 32.093 degrees Fahrenheit, with no variation, for each of the days.

Going about the rhythm of our February pruning, at times the only sound is the stainless steel snip of our pruner blades, with occasional chirps and chortles from our (supposedly) mute swans.

Despite the silence, we are a little less anxious than we were last year at this time.

Our sturdy vines survived last winter's unprecedented cold exactly as we had hoped, with the nectar of last summer's bountiful harvest perfecting itself in the safety of our winery's stainless steel tanks.

Last February 2nd, Bucky our vineyard groundhog failed to rouse himself from the warmth of his den beneath a Petite Pearl vine.

This February, the snow above his warren is untrodden again, on the cusp of Valentines Day.

We'll take Bucky's slumber to mean we expect the gelid conditions to linger, although with each passing day, the sun, when it reveals itself, feels just a bit warmer on our cheeks, and the chatter of mute swans grows louder.

Cold temperatures linger, but there is a new warmth to February's sun.

Persephone

The ancients had a goddess for this day: Persephone.

Whisked away to the underworld after the harvest, Persephone was said to take with her all that was green and vital, leaving mortals behind to languish in a barren realm. 

And then, this joyous day, the vernal equinox. From a cleft in the earth, Persephone was said to return, and once more, the world would be awash in color and rampant with new growth.

Today, the first day of spring, found us out in the vineyard, continuing the work we began many cold months ago: pruning back last season's grape canes, leaving behind just those few choice buds we select to bear this season's fruit.

Was the vineyard suddenly different today? Were we awash in color? Did the earth's mantle cleave and release a new birth of life?

Well, all things are relative.

This first day of spring in Canton, Ohio, the sky was leaden.

Snow flurries fell.

A raw wind blew.

Although the blanket of white we tromped through for most of our winter was largely gone, it was not replaced by a verdant carpet, but rather by mud and a thatch of brown turf.

As we finished up the Marquette block and made steady progress through the Frontenac Gris, the rhythm of stainless steel blades snapping through last summer's now dormant growth competed with raucous avian rivalries from a rapidly thawing lake.

Each pruning cut revealed the familiar kiwi green that has fed our winter weary souls through a long frigid season: the response of our resilient grape vines to a season of brutal cold. Encased in dull brown cells of insulating tissue, the vital force of each plant remained visible, even in the dim light of a sun shrouded by flurries. 

And yet, today, something WAS different:

Pruning cut, March 20, 2014
At a certain point in the afternoon, as the sun burned through gray, the brown turf warmed just a few more degrees. 

Not enough warmth to feel a discernible difference on wind chaffed skin, but enough to trigger the movement of vital fluids from grape roots drenched within a thawing terrain. 

Up through craggy six-year old trunks, through cordons stretched horizontally across galvanized trellis wire, and eventually, out, out into the sunshine, the vital fluids of each plant flowed.

The difference we experienced today: those kiwi green pruning cuts glistened.

Sap is rising. The grape vines bled, which is a good and beautiful thing.

Nutrients and vitality pulsed from the ground below, priming each vine's vascular system, cleansing each pruning wound.

As our clay soil thaws and spring rains fall, our terrain will likely persist for some time in its sodden state. (Which is hardly surprising in our region of the world, where a massive clay bed fed the nation's leading paving brick industry, centered right here in Canton, Ohio.)

Canton paving bricks in autumn, a legacy of our terrain.
Days will arrive (soon, we hope) when bright sun will shine, and the temperature will rise above fifty.

On those days, our pruning cuts will gush, and we will delight, sure of Persephone's return.

Perhaps the earth did not cleave in our vineyard soil today.

But nonetheless, something new and vital rose from the earth below.

Perhaps it was not as dramatic as classical depictions of Persephone's return from exile in the underworld.

But for those of us who toil  routinely through seemingly changeless seasons, our reward is being present for subtle shifts in the status quo.

Today's pruning cuts were no different from thousands we made all winter.

Except that they WERE. 

They glowed, saturated with nectar arising from a wakening earth.

Balance

Petite Pearl grapes in the South Vineyard, August 2013

These deep days of winter, with the vineyard blanketed in snow, we think ahead to the warmest days of summer.

We contemplate the fruit these now bare twigs will bear.

The foliage is long gone. A few shriveled grape clusters cling through wintry gusts. Sometimes it is hard to remember the verdant abundance of a few months ago.

But summon those summery scenes we must, for decisions we make now will affect the yield of September.

In winter we prune.

We cut the prolific growth of last summer back to a few stubby spurs, short woody stubs sprouting from (increasingly) gnarled trunks below.

We place last summer’s canes—brittle tawny twigs, still kiwi-green in the center—in yellow plastic harvest totes that in the fall held sweet fruit. We weigh them.

Pruned Marquette canes in a harvest tote, to be weighed.
There is a formula for balanced pruning.

The weight of the canes removed from each vine gives us a sense of that plant’s vigor. The vigor of last year’s growth lets us know how much energy is stored in those bare trunks and hidden roots to feed next year’s crop. The formula lets us know how long to leave the spurs on top of the permanent trunk.

Two, three, or four buds per spur? The weight of the prunings and the grape varietal they come from will help us to know.

The goal is balance: curbing the vine’s prolific tendencies. Producing the best yield, without stressing the plant’s permanent health with too much fruit.

Balance: just enough vigor, but not too much.

Balance: visualizing prolific growth that will emerge from the buds that remain, projecting how many buds might be lost to late season frost.

Contemplating autumn’s sunny abundance, on a frigid January afternoon in a snow capped vineyard: its own form of balance, I suppose.

The Vineyard Sleeps

For several months we have had occasional hoarfrost in the morning, crystalline frost on dying foliage, a smattering of flurries and squalls.


But one day the first heavy snow of the season arrives, and stays, and the vineyard finally slumbers.

There is something remarkably peaceful about the first snowy vineyard sunrise of the season. The snow muffles all sound, the ground is covered, the lake partially frozen.

That is our signal that the post-harvest work of the vineyard is mostly finished. What did not get accomplished will wait until another season, for these are the days when we start to look ahead.

In a few short weeks the crucial work of pruning begins, when last season's growth is removed and we choose how many buds to leave on woody spurs. Latent in each bud, is next years's life: rampant shoots, lush foliage, delectable fruit, for these few months slumbering in a quiet, snowy vineyard.
