Marvellous and Ominous Blasts From the Past

They don’t call it Merveille des Quatre Saisons for nothing. The lettuce variety, a pre-1885 French heirloom, according to the seed catalogs, can handle just about anything the weather gods throw at it. This gorgeous head of “marvel of four seasons” lettuce, see above, is one of half a dozen that sprouted from lettuce stumps that I had left for dead in my garden last fall. I didn’t notice them until early this spring when they started sprouting and then formed characteristic rosettes of loosely folded ruby-tinged green leaves.

Meanwhile, my new spring crops-including some Merveille des Quatre Saisons, several spinach varieties, and other greens-which I started in the greenhouse and moved into garden in mid-March, are thriving outside, especially those that I kept under a row cover on hoops. They’ve dodge all of the hazards the cruel world could throw at it so far, including some light freezes and tree-toppling wind storms.

A groundhog, to be sure, could make short work of them all, and one recently showed up, happily grazing through my cilantro crop. I don’t think it’s the same one that slowly but surely ate its way through my garden last year. That groundhog (which I caught and released, though perhaps not far enough away-less than a mile from here) didn’t like cilantro. This groundhog clearly favored it over eight or ten other nearby choices. It’s going to be one of his last meals in my garden, if I can help it. I’m borrowing a trap and setting it ASAP.

Survivors of the Winter of 2019-20

I’m sometimes surprised to see what plants from my fall garden have managed to survive the winter and are surging back to life in spring, often with no help from me. This past winter, I didn’t bother to put a row cover over anything, as I have generally done in recent winters, and therefore wasn’t expecting any early harvest. But this March, in my Roxborough community garden plot, a half dozen long forgotten lettuce stumps sprouted beautiful red rosettes of lettuce leaves, and a patch of cilantro that produced little in the fall was flush with new growth.

Hakurei Turnips: Marvel of Almost All Seasons

I dug up some turnips and radishes from the thawed ground in my garden on a balmy 60-degree day in early February and roasted them for dinner. The radishes were firm and surprisingly tasty for midwinter. As for the turnips, though they look good (see photo), they had a mushy texture-nothing like they are in their crisp prime, and no wonder. They’ve frozen and thawed quite a few times in the last couple of months. But they were certainly edible, earning all the more respect from me.

Hakurei turnips are the one crop that never fails in my gardens. Almost all the seeds germinate, even the few I’ve spilled in the paths between rows, grow to maturity. Planted in succession from early spring into the fall, they yield a continuous harvest of tender little turnips and greens that are as good as the turnips themselves.

Survivors of the ‘Winter’ of 2016-17

Overwintered spinach that in mid-April is already starting to bolt

Note to self: next time you plant a crop of spinach in the fall intending to keep it going through the winter and into the next spring, jot down the name of the variety or varieties you plant.

I’ve attempted to grow spinach through the winter for three years in a row. The first of the three crops was a spectacular success, yielding a light harvest of baby spinach in the fall and bulging bags full of mature spinach from March into June. (And that was entirely inadvertent, as I explained in a post at the time.) In the fall of 2015, I planted hundreds of spinach seeds but just a few seedlings sprouted-and promptly keeled over and died long before winter set it.

collard green

This past fall, I planted two varieties, both of which got a healthy start. They survived the winter under a row cover in fine shape.But now that spring has arrived and I have uncovered them, they are already bolting after just one modest picking. What the heck? I was counting on a continuous harvest right up to the start of summer! I had alerted friends and neighbors to prepare to help me eat it all. Then this: my patch of spinach, lovingly tended all winter long, is going to yield a couple of servings.

cilantro

The weather is obviously one factor. And I probably kept the row cover on too long. We had a number of days during this past so-called winter when the temperature got into the 70s, which means it must have been in the 80s under the row cover. But the varieties of spinach I have planted these past three winters was surely also a factor in the wildly varying results. Trouble is, I have no clue what varieties I’ve planted. I’m going to try again this fall, but due to my lack of notes, I’ll be starting from scratch in my effort to get it right.

chives

Oh well. I’m getting at least some homegrown spinach this spring. And several other crops are coming back: one collard, a kale and chives (no surprise with any of them). Unexpectedly a couple of cilantro plants are also coming back from a crop that I had given up for lost last fall. Most surprisingly of all, some parsley that I started from seed about this time last year and yielded a continuous harvest last summer is now coming back strong this year. Hurray for the parsley! It is showing no signs of bolting. I’ve already made one batch of chimichurri with, I hope, many more to come.

Growing Spinach Under Snow

My Mt. Airy spinach house, Jan. 6, 2017, after a 1-inch snowfall

I didn’t want to toss off the blanket of snow and pull up the row cover to look, but the crops underneath are deep green and glowing in the sunlight filtering through after a 1-inch snowfall covered my backyard garden last night. The temperature will dip into the low teens tomorrow night. Most of my plants should survive-I’m not so sure about the radish sprouts and last little heads of lettuce-but the spinach, kales and one collard plant shouldn’t be fazed.

Nice place for spinach on a snowy day

I’m less confident about whether the tunnel covering them will make it through the winter. The hoops are too widely spaced and the cover is a mere light-weight Harvest-Guard frost blanket. So far it’s holding up under wind, rain, light ice and snow. I’m not going to press my luck too far, though. If there’s more than a few inches of snow in the forecast one of these days before winter is over, I’ll take steps to shore it up.

Meantime, here are the salad fixings that I picked on New Year’s Day. Yes, it was a very tiny salad. Keep in mind, folks, the main goal of my overwinter garden isn’t winter production as much as it is a really early spring flush of greens, from plants that will continue yielding cuttings right up to the edge of summer.

Spinach Unfazed by Winter’s First Big Punch

Winter arrived in Philadelphia this past week. For a couple of days, the temperature didn’t get out of the 20s. The low dipped into the teens on two nights. The bout of winter ended with half an inch of snow capped by freezing rain.

The flimsy row cover that I stretched over half hoops to shelter my fall crops miraculously survived the winter. I was certain it would either be flattened by ice and snow, or ripped to shreds by the winter winds, or both. We had perhaps a dozen snow falls this past winter, most just an inch or two, but they were icy and wet. The fabric withstood it all, and was barely worse for the wear at winter’s end.

The crops underneath the row cover didn’t fare as well. A solitary spinach plant, a single frilly mustard and four kale plants survived. The Brussels sprout that I planted in September, and that never did anything in the fall, grew into a beat-up bonsai, but there were little buds in the leaf joints. I painstakingly harvested about a bite of what I am calling overwintered micro Brussels sprouts.

I also planted some Merveille de Quatre Saisons lettuce seeds in September, and got a fine but small fall crop. I harvested most of the plants on Dec. 11, since I was about to leave town for nearly a month. But I left some in the ground just to see whether the cultivar would live up to its name. The plants were still alive, albeit barely. They had survived several spells of single digit temperatures. But they had rotted away by March. I’ll give the variety half a credit for yielding a nice harvest in December, even after several hard frosts, and for lasting into the new year. It’ll be Marvel of Three-and-a-Half Seasons to me from now on.

A few of the kale plants, from seedlings I planted in September, survived under the row cover but look quite sickly at the moment. I’ve now liberated them from the row cover and will hope for a resurgence of growth in the coming weeks.

Several arugula plants also survived. The leek seedlings I planted in the fall are very well established and look ready to plump up.

All told, it’s nothing like the bumper crop of overwintered spinach that I had last year. But the survivors are a start for the growing season of 2015 now getting underway.

Lettuce in Philly in the Snow

My crop of September-planted lettuce, mustard and kale, which has been draped with a light floating rove cover since October, yielded a very nice harvest on Dec. 10.

I picked fairly heavily in light of the prediction of a chance of a bit of snow. I’m determined to keep some plants going for as long as possible this winter. I have no hope of duplicating last year’s bumper crop of overwintered spinach and lettuce, but I’d like to try to keep something alive until spring. But I don’t want to sacrifice all of my crop to that experiment.

Who knows how long the light covering will keep my crops alive this winter. So far, they have done far better than expected, having survived several freezes into the mid-20s already.

On Dec. 11, sure enough, we got a light skim of slushy snow. I dropped by the garden, found the snow-dusted row cover intact, and the plants underneath just as happy as clams.

Last Avalanche of Overwintered Spinach

It’s now June and I’m still getting bulging plastic grocery bags full of last fall’s spinach — and big freezer baggies of red leaf lettuce — out of my little plot. The spinach and lettuce survived the frigid winter, as well as the shock of getting pulled up and transplanted to my new plot in the Garden RUN Community Garden. They have 06-02-14 overwintered gardenyielded a continuous harvest of spinach clippings since March. The plants have been taking turns bolting for the last month or so. A few of the spinach plants have still barely begun to bolt. I clip them as soon as they start to shoot up, before they turn woody, when they’re still tender and sweet. Guess I’m going to have to make an extra-spinachy batch of my favorite curry, and use my other old favorite spinach recipes that I’ve posted on my Seasonal Chef web site.

Hardy Survivors of the Polar Vortex

Who knew? Spinach, radicchio and even lettuce can survive a bone chilling winter in Philadelphia under nothing but a thin floating row cover and a heavy blanket of snow.

I’m still quite new to gardening in this part of the country, after 25

My garden plot in January

years of gardening in relentlessly warm and sunny L.A. So I was impressed that said row cover kept my crop of fall-planted salad mix going into December, through several dips of the thermometer into the high 20s. I had intended to retrieve the row cover before I left town for a Christmas visit to Southern California, figuring it would do nothing over the winter other than getting battered by bitter weather. But I never got around to that chore before my departure. By the time I returned in January, the row cover was buried under snow — and stayed that way for the next two months.

Philadelphia got hit with several blasts of the polar vortex this past winter. The temperature briefly dipped below zero degrees Fahrenheit on a couple of occasions and stayed in the teens and single digits for days at a time. On top of that, we had more than a dozen significant snow storms in what turned out to be one of the snowiest winters on record in Philadelphia.

Weeds and spinach in April

Weeds and spinach in April

I didn’t return to my plot at the Garden R.U.N. community garden in Roxborough until April. The row cover was still there, snuggly tucked in place. Since I have been upgraded to a sunnier plot this year — my second at Garden R.U.N. — I pulled it up so that I could reuse it to cover my early spring plantings in my new plot. Behold! A thicket of weeds that had clearly appreciated the extra warmth, and amidst the weeds, a profusion of thriving, succulent spinach plants, a dozen or so radicchios, and a few red lettuces. I couldn’t believe my eyes. I figured the radicchio roots might survive and sprout new growth. But the spinach and lettuce!?! As I said, who knew? Everybody but me? Should I have been surprised, dear readers with more experience than I have growing in this part of the world? Was the insulating snow my garden’s saving grace?

transplanted survivors in my new plot

I transplanted quite a few of the survivors of the polar vortex to my new plot, knowing they wouldn’t appreciate getting uprooted and moved, as mature as they were. But they have continued to do quite well, yielding as much spinach as I have needed in recent weeks. And I like lots of spinach.

Next fall, I’ll plant a crop and cover it up, with the expectation that I’ll have an early spring harvest.
