Gardeners, keep an eye on the jet stream

Rows of garlic, their protective, winter blanket of straw removed, will easily survive cool spring days

With the growing popularity of home gardening there must be a lot of people on a steep learning curve trying to come to grips with the apparent uncertainty of the weather.

After all, spring seemed to have arrived early in the Canada-U.S., Great Lakes area with temperatures in the first week of April that were seemingly warm enough to allow for the planting of early hardy, veggie crops like peas, beets, carrots, onion sets, and potatoes.

After years of gardening that should have made me know better, I again found it hard to resist the temptation of eagerness to get started. But I compromised, planting only a couple of rows of early edible pod peas; after all they are called ‘snow peas’ for a reason, I pseudo-rationalized. I also planted a row of onion sets, and two rows of Chieftain red potatoes. The date was April 6. I’ve never planted potatoes that early. Meanwhile, I held off on planting beets, swiss chard, carrots and radishes.

I should have held off entirely, especially the peas. That’s also considering I plant untreated seed; that is, seed not coated with fungicide to keep it from rotting in the ground if the soil temperature is not warm enough for germination. A few more days of warm weather, and the pea seeds and I might have got away with it. There was evidence of germination just getting started. But now, April 18, there’s no sign of little, green pea-plants emerging. I few might survive, but the rows will likely have to be replanted. With temperatures now forecast over the next few days to be below freezing at night here on Ontario’s Bruce Peninsula, the two rows of seed potatoes buried several inches in their rows should be okay; but just to be sure I’ve covered them with a generous layer of straw. The same goes for the onion sets.

Two rows of seed potatoes planted, covered with straw to help insulate them from the cold. After it warms up the straw can be raked aside and mulched around the plants to prevent potato beetles.

Meanwhile, in the back garden, the numerous fall-planted rows of garlic are looking good. They will be okay without the straw blanket I covered them with for the winter and raked away a couple of weeks ago to give them sun. Garlic, fast becoming a popular crop in southern Ontario, is hardy enough.

I’m not a newcomer on this planet, having lived my ‘three-score years and ten’ and more, but in memory it seems to me the advent of spring, once arrived, was much more reliable than now.

It’s well known that the location of the jet streams, the high altitude winds that circle the globe  in temperature regions, is a major determining factor in weather. In the northern hemisphere, the generally west-blowing jet stream keeps colder temperatures north of us, and warmer, south. As the seasons change with the sun, the jet stream used to move south and north in a fairly stable way. But recent years have seen a growing school of thought that climate change is weakening the jet stream, as the Arctic warms relatively faster than tropical regions. As a result, The jet stream’s pattern has become more erratic with deep dips to the south that sometimes appear to get stuck, or ‘blocked’ over certain areas. I keep a close watch on jet stream maps, and have observed, anecdotally, that often in recent years it has dipped down in large tongues or nodes and lingered for long periods of time south of the Great Lakes. Sometimes, it appears to even fragment and get scattered. Depending on the seasons, all that has resulted in long periods of extreme cold weather in winter, and prolonged cool weather in spring. The spring of 2020 at this time, was similar to what’s happening now: an unusual warm spell in early spring, followed by much colder weather, and then a serious snow event in April. I note snow is in the forecast for this week.

Now, snow in April is not unusual. I well remember driving to work one morning years ago in June with snow coming down. But it’s the sudden, dramatic changes and extremes that now seem new and unusual.

The experts admit evidence of the impact climate change is having on the Jet Stream, and therefore weather, is still inconclusive. They do, after all, have a duty to be precise in reaching their conclusions. Meanwhile, the skeptics can find all kinds of supposed reasons why it’s not happening. I choose to believe climate change is having a destabilizing effect on the jet stream that needs to be taken seriously.

From the point of view of gardening, and farming, I would say you are best advised to keep in mind there is a new norm happening: the weather is becoming more erratic. If it seems too good to be true that warm spring weather has come too early, it more than likely has. And you should take a wait-and-see attitude to planting until the weather warms up to stay. Late April, early May is still a good time to plant cool-weather crops. They won’t do much growing until then anyway.

Above all, keep your eye on the jet stream: where it is, and where it’s expected to go. I recommend a new, interactive ‘global’ jet stream map put online by U.K.-based netweather.tv.

Successful gardening in a time of climate change: soil temperature, not the date

There’s snow peas in there somewhere, under the snow.

What’s with the weather?

Here in southern Ontario, Canada, in The Great Lakes region of North America, as we approach mid-May, to say the weather in ‘unseasonable,’ is to put it mildly.

No sooner is that word out of my fingertips and on the cyber-page than it seems incongruous in the circumstances: it’s anything but mild outside. It’s cold, and wintry cold at that, with sub-zero, night temperatures in the seven-day Environment Canada forecast. Continue reading

Growing your own food: gardening and weather, the first learning experience

jetstreamapr22

I’m Canadian, eh. And a modest market gardener, living and working in a sparsely populated rural area. So, I guess I’m more culturally obsessed with the weather than a lot of people in Canada who now mostly live in big cities. It wasn’t always so; but more about that later.

I have been reminded yet again that keeping tabs on the now-frequent wanderings of the Jet Stream is key to understanding Canadian weather; and in particular, here on the Saugeen/Bruce Peninsula, and elsewhere in southern Ontario. This comes in the midst of winter’s virtual return, several days of freezing cold weather, a month into the spring season of the Northern Hemisphere. It’s supposed to be a lot warmer than this. Gardeners are supposed to be busy planting hardy, early crops like snow peas, even potatoes by now; and rejoicing that a healthy-looking crop of new garlic has emerged, not worrying about even it, surprisingly tough as it is, being damaged by one hard frost after another.

Don’t play political games with climate change

earthOn a Cosmic scale our beautiful little blue-green jewel of a planet is some kind of rare miracle – perhaps the only one – in a vast Universe of unimaginable extremes of blazing hot and deep-freezing cold.

But global warming and the resulting climate change is now in the process of showing the world – that part of the world that’s watching, at least – how delicately balanced and vulnerable that miracle is.

Market gardeners and other farmers know a few degrees of temperature either way during the growing season, and the lack of a certain amount of reliable rainfall – say, at least a weekly centimetre or two, about an inch – can make all the difference in the health and well-being of crops.

Seeds of hope, rural roots

Irish Cobbler potato plants looking good, June 7

Let’s look on the bright side again.

Let’s plant some seeds of hope.

Let’s do what we can, where we can, while we can.

Here at Cathedral Drive Farm, surrounded by Hope in reality and spirit, the garden is starting to look good. I can look out my second-floor office window and see multiple rows of sweet corn that a week ago emerged, including quite a bit of seed left over from last season. Continue reading

Empty words are the enemies of hope

This one’s a no-brainer, right? “Hope,” I mean as the Daily Prompt, and this blog, called Finding Hope Ness.

hope

How many times have I said I’m “surrounded by hope,” as in Hope Bay, the Hope Bay Nature Reserve, Hope Bay Forest, and Hope Ness itself? That’s a rhetorical question, of course. But, in case you’re a first-time reader, the answer is lots of times; too many, as if saying it often enough, taking advantage of the coincidence of location, makes it real.

There is nothing more precious and yet so hard to find than hope. And nothing more sentimentalized.
