Late Winter Pluses and Minuses
Posted by piedmontgardener in Favorite Plants, Greenhouse growing, Native Wildlife, piedmont gardening, Vegetable Gardening on February 22, 2016
It’s been too long since I posted here. My apologies. Late winter in my corner of North Carolina has been a mostly soggy mess. And as I type this, yet more rain is pouring down upon my mushy landscape. I have been posting small items regularly on the Piedmont Gardener Facebook page; if you use that social media tool, you may want to check out the photos and announcements of relevant events that I post there.
As I’ve noted on the PG Facebook page, beavers have once again moved into the wetland adjacent to my creek. They have built a dam downstream and off my property, which has raised the water level in the creek so that every rain event involving more than a half-inch is causing the creek to overflow in numerous places along my property, even cutting channels into what has been a stable, flat floodplain for over 25 years. It’s a real mess, and we’re not sure what, if anything, we can do about it.
The beavers are actively foraging all up and down the creek. In addition to harvesting a few saplings, they even “tasted” two of the Leyland Cypresses still standing beside the creek. To discourage them from returning, I sprayed the entire lower trunks of all the Leylands with a deer repellant spray in the hopes that it would make them taste bad enough for the beavers to ignore. So far <knock wood>, it’s working, but all this rain probably means I need to reapply the repellant.
But not all my landscape surprises are less than wonderful. Case in point: a pair of Pileated Woodpeckers appear to have chosen a sycamore just across the creek to raise this year’s brood. Until the forest leafs out, I can see this spot from my living room window and back deck. That’s a good thing, because when I try to walk near this tree, the woodpeckers make it clear that I am not the least bit welcome.
Another pair of late-winter nesters has settled in, as usual, in the wetland forest — Red-shouldered Hawks. They often lurk in the trees near our backyard bird feeders, but I haven’t seen them catch any songbirds. Frogs, salamanders, and earthworms, on the other hand, seem to be dietary staples. Wonder Spouse took that spectacular hawk photo two days ago when it decided to hunt from a tree in our backyard. He actually took the shot from inside our house. He is a wizard with his camera — and his post-processing software.
When we’ve gotten a few back-to-back days of sunshine, we’ve been hard at work preparing the vegetable garden for another season. All my seeds have arrived, and last Wednesday (2-16), I sowed my first batch of greens in my germination chamber. The ones in the above photo germinated in two days! I’ll enumerate the spring garden veggie varieties I’m trying in a new post soon. All the lettuces germinated instantly, along with baby kale and radicchio. The spinaches and parsley are only just now showing signs of germinating, which is entirely normal. When they are all well up and moved out of the germination chamber, I’ll sow another batch of spring veggies.
The two varieties of onion plants I ordered arrived mid-week, and I managed to get them all planted in their garden bed yesterday. I know they don’t look like much now, but if the voles will leave them alone, we have big hopes for these.
It’s always amazing how these stubby little onion starts that arrive with shriveled roots plump up in just a few weeks. I was delighted to get them planted the same week they arrived. Usually I’m not this organized and they wait a week or more. I’m hoping my efficiency will pay off in bigger bulbs. Stay tuned.
We’ve had a few bouts of deep cold and some ice — mostly freezing rain — which damaged my Magnolia stellata ‘Royal Star’ flowers. They opened too early, thanks to the absurdly warm December we had here. Fortunately, not all the buds opened before the cold, so I’m able to enjoy a round of new blooms during our current milder spell of weather.
In addition to the witch hazel ‘Amethyst’ blooming well in the first photo of this post, my Cornus mas ‘Spring Glow’ trees are bursting with bright golden flowers. I’m hoping they will cross-pollinate each other this year and produce some of the red berries that give them their common name: Cornelian Cherry. I was thus heartened to see a pollinator on these flowers yesterday.
Of course, spring bulbs are well up. My crocuses were eaten by deer before I remembered to spray them with repellent. Snow drops and myriad daffodils are all loaded with buds and will soon be glowing in the landscape as it wakens from its winter slumber. Meanwhile, the lushest, greenest parts of my yard are the lichens, soft and fluffy from abundant rains.

Is it just me, or has this already been the longest winter ever? Oh, sure, we get occasional very brief moments of temperatures in the upper 50s, but they’re usually accompanied by rain. And, yes, I know I’ve had it easy here in the southeastern Piedmont compared to those poor
fools folks in New England currently buried under three feet of snow and counting.
Even so, my winter-blooming plants are way behind their normal schedules. The only one currently blooming respectably is the pink flowering apricot in the above photo. My two other apricots — Peggy Clarke Senior and Junior — are only just starting to try to open a few flowers here and there. Often by this time of year, the apricots have been blooming since late December. Ditto for my January Jasmine. If I scrutinize the flower buds, I can see one or two showing peeks of bright yellow, but no open blooms. They didn’t make their namesake blooming month at all this year. The hellebores are also way behind. I can’t even find any flower buds showing yet. The snowdrops are just pushing up out of the soil, and so on and so forth with all my early bloomers. It’s enough to discourage any gardener.
But for the last two days, suddenly my Northern Cardinals are singing again. Since autumn, they’ve been cheeping among themselves at the feeders, but now the bright scarlet males are perching in the treetops bragging about their good looks for all to hear. Their surge in hormonal harmonizing defies winter’s tenacious grip, and reminds me of the sun’s lengthening daily presence. So I decided to take my cue from them and start some vegetable seeds in my greenhouse yesterday during a “warm” spell.
Personally, I am eager for salad season. An array of fresh-picked spring greens lightly dressed and perhaps mixed with a few other veggies, some nuts or berries or cheese — I’m salivating just writing about it. This excitement annually grips me as I survey my seed catalogs, which probably explains the assortment of seed packets I pulled out yesterday.
Yes, as usual, I’ve probably gone a bit overboard. But that’s why I’ve planted some of each of these in the greenhouse now. I want to prolong salad season as long as I can. You see, the problem with spring gardening in the southeastern Piedmont is that the optimal growing conditions for these veggies can be depressingly short. Sometimes the temperatures leap into the 80s in early April and never look back.
My plan is to grow the seedlings in the greenhouse until the nighttime temperatures stop regularly plunging into the teens. When that happens, I’ll transplant them into a garden bed, mulch them well, and cover them with a tent of the heaviest grade of spun garden fabric — the kind designed to protect plants from nighttime temperature drops. It’s a gamble, but the pay-off is totally worth it.
The lettuce seeds are tucked inside the germination chamber, where the propagation mat warms them from below to raise soil temperatures just enough to enhance germination rates. The spinaches, greens, and beets are sitting in flats on the greenhouse bench beside the germination chamber. They really prefer cooler soil temperatures, so that’s what they’re getting. I’ve never tried sowing beets indoors before, but the seed packet suggested it, and my germination rates from direct sowing have always been unpredictable, so I figured I’d try it this way. Of course, I’ll be sure to let you know the results of the experiment.
I use fresh potting soil for germination operations, and I fill all the cells and water them thoroughly before I start planting. By moistening the soil before sowing, I don’t risk dislodging tiny lettuce and spinach seeds by adding water later. Lettuce seeds especially need to be just barely covered. The only way to achieve the control I want is to slide the seeds in place one at a time into the pre-moistened soil. The green fabric beneath the flats is capillary cloth; this greenhouse staple holds excess water which can be pulled up by the seedlings as they need it. It allows me to maintain more consistent growing conditions inside my little greenhouse.
The top on the heated germination chamber ensures optimal humidity and warmth for encouraging seedlings to emerge. As soon as they do, I’ll move them to a bench. The enclosed chamber is too humid to keep growing plants happy. Plus, I’ll need the space for the next round of seeds I’ll be planting in a week or two.
Today, the winds are howling again, and nighttime temperatures are predicted to be in the low 20s, which translates to the mid-teens at my house. I confess I feel a bit less frustrated with winter’s tenacity, now that I’ve started my own spring revolution in my greenhouse. I encourage all my fellow Piedmont gardeners to join me in this rebellion.

Fast forwarding into Spring

OK, there’s still a pile of snow in my back yard. Really. It was a huge pile from cleaning our back deck, and it’s still not quite gone. But don’t tell that to the Spring Peepers or the Red-shouldered Hawks nesting on the floodplain, or the Red Maples throughout my yard. They all seem to be persuaded that Spring has arrived. It hasn’t, of course — not quite yet. But it seems as if the plants and animals in my yard have been biding their time, waiting for the frigid air to exit so they could explode into Spring Mode.
Most of the early-flowering plants had impressed me with their patience, not showing a hint of bud break as the arctic air ruled my region. The flowering apricots were hit pretty hard, of course. Many just-opening buds were browned by freezing temperatures. But the unopened ones still tightly shut have now opened with enthusiasm. The air around my front yard is fragrant with their perfume. I am delighted, and so are the honeybees finally making their appearance during recent warm afternoons.
The Cornus mas trees burst into spectacular bloom, yellow spotlights in a mostly brown landscape.
The Magnolia stellata ‘Royal Star’ had been exhibiting unprecedented patience with the weather, but recent 70-degree days have caused its flowers to begin opening.
The snow drops survived being buried by six inches of snow and ice and are in full bloom.
And the Witch Hazel ‘Amethyst’ is scenting the breezes with the fragrance of gorgeous purple flowers.
The warmer temperatures have all the early-nesting birds displaying territorial behavior as they pair off and claim nesting sites. Woodpecker drumming punctuates the air from dawn to dusk.
And the salamanders somehow managed to complete their late winter mating activities despite the cold and ice, as evidenced by this glob of eggs in our tiny pond.
Of course, my gardening fingers got itchy the minute the weather warmed and the frogs began chorusing 24/7. I got out the seeds that I’d ordered and contemplated my strategy.
Because I can’t expect the spring-like temperatures to last just yet (They’re on their way out as I type this), I can only start as many containers as will fit at one time in the germination chamber in my greenhouse. I settled on starting a few of all of the greens I’m trying this year (4 lettuces, 2 spinaches, and an arugula) plus the four flower varieties that require the greatest amount of time to reach blooming size. I sowed the seeds last Thursday, and here’s what they looked like this morning:
The nonpelleted lettuce seeds are well up. The coated lettuce seeds are still meditating on the merits of germination. One Tyee spinach has emerged; spinach is always slower than lettuce. All the arugulas are up and growing. And the dahlia seeds I sowed have begun to emerge — the first of the flowers, and a bit of an early surprise.
Now that I’ve got seeds going, it was time during our first warm weekend in forever to return to the vegetable garden and begin to prepare the early spring garden beds. I’ve got one weeded and ready to go for the greens. I’ll do more as weather and my aging joints permit.
Greeting me with enthusiasm were the chives I grew from seed two years ago. I was a bit worried that our prolonged freezing winter temperatures might have killed them. I worried for naught. These beautiful, delicious herbs are well on their way to growing tall enough to once again season salads, eggs, and whatever else can use a light taste of oniony goodness.
This week’s return to winter temperatures will be harder on me than the plants and animals, I imagine. It felt so wonderful to be back in the dirt, pulling weeds, cleaning up old flower stalks, discovering sudden flowers tucked into various parts of the yard.
On the other hand, my creaky joints could use a day or two — OK, maybe three or four — to recover from my pent-up gardening enthusiasm. Perhaps I’ll even feel a bit nostalgic toward this latest round of wintry temperatures. Because now I’m sure — Spring really is almost here!
