With a sunny, happy winter day
tucked in for the night on Sunday, it seems it was the calm before the storm.
Sitting in my home office loft
writing and looking out at the clear, twinkling, movie-set New York skyline
just beyond, it seemed unholy to think that in a short time, we’d be bracing
for a whopper of a winter storm. It’s already been labeled
#Snowmaggedon2015. And then it wasn’t. Somewhat of a bust of a
storm but still a whopper.

I’ve just about completed the
Recommended Garden books review for Garden Glamour friends and fans. With
nearly a dozen garden and horticulture books featured in my list of
recommendations from 2014’s just-published or discovered/introduced to me at
events, symposiums, or lectures, this is a gardening, growing, and breeding
book list you won’t want to miss.

However, with the news’ escalating
drama for 2015’s first major winter snowstorm changing up, forecasters are now
calling for a major blizzard.

Yet judging by even my New York
Botanical Garden’s Landscape Design alumni group, concerns about the extreme
cold and its lasting effect on the plants is on high concern alert. One
member wrote to ask last week — before the blizzard warning — if there is
anything any of us could recommend so that her beloved hydrangeas would be in
good form to charm the expected visitors to her slice of Eden as part of a
larger garden tour.

Last year, as many of you know, the
growing season lost the charm and beauty of many of our most beloved summer
favorites – especially the flowering hydrangeas – specifically, the Hydrangea
macrophylla – the bigleaf or “mophead” hydrangea that gently whispers “summer.”

I adore them. I inherited the
‘Nikko Blue’ when we moved to our home and added the ‘Lady in Red’ as sassy,
summer accessories to the red roses that border the Coral Bark arbor design I
did some years ago.

In turn, I use these red and blue
beauties to great effect for our Independence Day Fireworks party when friends
and family gather to officially kick off the summer, celebrate Mother’s
birthday! and watch the fireworks set off in the marina right below us.
It’s grand ol’ flag kind of an affair.

So all can imagine the vast
disappointment when last year yielded no/zilch/nada hydrangea blossoms.
Not only the beloved hydrangeas were a no-show, many other woody
perennials such as caryopteris, and some evergreen shrubs, including Cherry
Laurel, Prunus laurocerasus suffered.

No. Those of us in the garden

hoping for that miracle that Mother Nature can provide. It was not meant
to be.

However, their “failure to launch”
was not due to the Polar Vortex or the bracing winter cold that strangled most
of the Northeast last winter. I don’t want to dismiss the plunge — It
didn’t help to have record-breaking cold. But that’s only a part of the story.

Woody Perennials, shrubs, and trees
go dormant. According to North Carolina State University Cooperative
Extension (NCSU), “As temperatures drop, growth slows and many
plants begin winter acclimation. Cool temperatures and shorter days
initiate the first phase of hardening, allowing plants to withstand a frost but
not a hard freeze.”

And that was the first punch.

Normally, one does not prune or cut
the woody stems of the hydrangea macrophylla
because they bloom on old wood. However, last spring’s circumstances
were extraordinary. So the cuts/pruning was made. It was the
sacrifice that was needed. And the hydrangea leaves came back full and
green. No blossoms, of course, but the plants came back healthy.
Gardening is a hopeful pursuit.

The cherry laurels surrounding our
water garden survived the winter with elegance and grace – I wrote about them
on Garden
Glamour: Splendor in the Snow last year, noting they looked for all
the world like ballerinas in repose after one heavy snow storm. Yet they
bounced back with equal amounts of grace and strength.

Then, a kind of pathogen seemed to
settle in. After I determined the shrubs needed to have the compromised
leaves removed, we – my husband and mother and me – raced to implement this
course of action. The curious result – if you can call it that – is that
the meticulous removal of the leaves on the cherry laurels on one half of the
water garden rebounded with dark green color and rich, robust foliage.
The other half? Not so much.

Why? You will ask, as a logical
garden question. The crazy, true answer is that were not meticulous
enough to remove all of the
compromised foliage — it was getting dark that late spring day, it was still
rather cold, it was a Sunday, and my husband and mother were getting tired and
cold. Me too. Plus, I wasn’t all that positive that my solution
strategy would work – so we had to call it quitting time.

As you can readily see, the
strategy worked on those cherry laurels where we remove the compromised leaves.
I fretted all summer that I didn’t stay out in the dark to complete
the work on the other shrubs. Oh, we took away a lot of their leaves but
not the ruthless, surgical work we did on the other half of the border… The contrast is striking.

Researching data for this article,
I see that my instincts were right:
Indirect Damage
The experts indicated the plants
may not be killed outright but can be stressed to the point that it is
predisposed to infection or infestation from pests that eventually kill it. In
fact, indirect effects of cold may occur more commonly than direct kills and
manifest themselves as cankers, collar rots, and dieback because of attack by
fungal and bacterial parasites. Sometimes disease damage is the only outward
sign of freezing damage.

Here, writer Lee Schmelzer cites
“Winter Damage” as a broad term that refers to damage in fall (!), winter, and
early spring (! – my exclamation point to note his “winter” is every season
except summer!)

He says fundamentally nearly all
winter damage is desiccation — freezing cellular water or indirectly by
freezing soil water making it unavailable for uptake. I refer to this as “sap-stop.

My experienced
nurseryman told me that the plants suffered because of a double punch.
The first, early frost occurred as
a surprise. The nurseries tried watering them to get the ice to protect/heat
the plants but the storm came too fast without much warning – thereby rendering
most of their efforts unsuccessful. The plants didn’t die – they just
rather seized up – as the “sap” was still flowing in these woody perennials’
stems.

The second tragedy occurred with a late spring
frost. Just as the cellular water was flowing – and we gardeners could see the
buds on the woody stems – the frost caused the “sap-stop.” We know how that turned out in the end. No blooms last summer.

Schmelzer explains cold kills by denaturing
proteins: “Plant proteins, among them enzymes, are temperature sensitive and
must remain intact and in the presence of liquid water to remain functional.
Cold inactivates proteins by making liquid water unavailable for their
function.”

A few years ago when the winter
snow storms started back with a vengeance, I wrapped our arborvitaes in sheets
after I swept the heavy snow off of them in order to prevent the snow from
getting inside and weighting them down. It worked.

And I probably should apologize to
the neighbors for making the garden look a little like a laundry room. Ha.
Plus, I used panty hose to help shake the snow off. Never a dull moment in the
world of gardens.
