Potatoes and lettuce will have to be replaced in the UK by small, mustardy root vegetables and dandelion leaves as a warming climate means we cannot rely on traditional crops, Kew Gardens has said.

Horticulturalists and scientists at the gardens are working to see which food plants can be grown to resist increasing pests and diseases, sunnier summers and warmer, wetter winters.

Next week, a new TV show exploring the secrets of the gardens will launch on Channel 5, showing how gardeners and scientists worked together during lockdown.

Helena Dove, who runs the Kitchen Garden at the facility, grows crops selected by scientists to see how they fare in a British garden plot.

She said that potato blight, a disease which can wipe out the whole crop, is becoming more common because of a warmer climate in this country. At some point it may become unviable to grow them, she and other horticulturists and scientists at Kew believe.

“Traditional potatoes are becoming very hard to grow because of blight,” she said.

Two strange-looking, knobbly little roots are being trialed instead, as they fare better in a warm climate and are resistant to blight.

The gardener explained: “We have been trying to grow root vegetables that could be substituted in the future. One we grow is oculus tuberosa, and tropaeolum tuberosum – the former is a little lemony root, it does really well, we are breeding it in the UK to make it more suitable for our climate. We also have a mustardy root crop, and sweet potatoes are doing well as well. They could be a replacement. We won’t know for tens of years but we have to start somewhere.”

Many who tried to grow lettuces during last year’s heatwave will have noticed it was an uphill battle. These hot summers are becoming more common, so Ms Dove is working to find hardier alternatives to the salad crop.

She said: “Lettuces bolt when it gets hot so we may not be able to grow them in hot dry summers. We are growing tropical leaves, orache, tree spinach, they are traditionally grown for their grain but the leaves are edible so they sort of replace spinach. We are also growing dandelion which have really bitter but delicious leaves. They will keep growing through anything. We are trialling all this for salad in the kitchen garden.”

The idea that potatoes need a perfect climate is nonsensical. They are grown in a wide variety of climates around the world, hot and cold, dry and wet:

potato-production

Harvest can certainly be adversely affected by the weather. Dry summers can stunt growth, but equally wet summers are not good news either, as farmers found to their cost in 2012.

However potato yields in the UK have been stable since 1990, following a period of rapid increase:

And UK summers are neither getting wetter nor drier:

As for lettuces, the dear lady seems to have totally lost the plot. Again, lettuces are grown in many countries with warmer climates than ours, including India and Spain. However, temperatures above 24C are not optimal:

https://www.worldatlas.com/articles/world-leaders-in-lettuce-production.html

Hotter countries, such as Spain, get around this by growing at cooler times of year, typically November to April.

According to the British Leafy Salads Association, the lettuce season runs from May to October, but planting can commence earlier if it is a warm spring. And the warmer the weather, the faster the leaf growth:

In other words, lettuce production is likely to benefit from a warmer climate, as planting can start earlier and finish later.

As for days over 24C, the summer of 2018 notwithstanding, they are still a rarity in England:

In reality, whether British climate changes or not, the change will be so slow that nobody will even notice, never mind the lettuces!

Brits fearing warming is about as silly as Canadians doing the same. Both countries are rather cool to cold, and as a Texan, seeing British websites calling 25 C a “heat wave” draws some incredulity.

In Canada we do manage a fine crop of rocks each year as the frost pushes them up to the surface.

And Ice. Again a fine crop each year. And mosquitoes and blackflies regular as clockwork without any need for global warming.

Regular crops, the kind people eat. Well, without the US and Mexico the fresh produce sections in the grocery store would be totally empty.

Oh wait. We do have some fresh produce grown in fossil fueled hothouses, where the CO2 is recycled to enhance growth.

But these will be a thing of the past once the carbon tax kicks in. It will be cheaper to truck food up from Mexico than grow it in Canada. Until something goes wrong and the food becomes as rare as a N95 mask.

Lettuce doesn’t like the heat? That’s strange… very strange. in 1954, heat wave in the summer in central Illinois (I was 8, okay?) not only made the garden vegs thrive, the chickens we raised for the table got fat on the peapods and greens that we threw to them. Lettuce not only grew, it GREW WELL. All it needed was watering, which isn’t really a big deal unless you’re a fake gardener (in name only). I’ve raised radishes in flower pots on my front steps. The cat loves the leaves to chew on and I get these hot-cha-cha radishes that spice up a salad like you wouldn’t believer.
These people really are afraid of everything in the natural world, aren’t they?

I just love how these alarmists talk about lettuce not growing in a hot summer. You don’t *plant* lettuce in the middle of a hot summer, you plant it before Mother’s Day if possible. By summer it has grown sufficiently to withstand the heat *if* (as you say) you keep it watered. It’s exactly the same with potatoes! And watermelon, And cucumbers. And cauliflower. And broccoli. And pretty much whatever!

OK, Tim, what else is on the menu for supper?

Yes, we put our garden in starting the first warm day in April, which was really the end of March in central Illinois. Up here near the WI-IL line, it’s cooler than usual, but the ground is thawed out, full of moisture and if my lawn is growing like Topsy and my neighbor’s apple tree is in full bloom, then it is NOT too cold to plant lettuces. Even the chives around the base of my mailbox have developed flower heads and are big enough now for me to harvest the stems, freeze them for future cooking episodes (like chicken soup) and the potted herbs on my front steps are thriving, DESPITE the temps in the mid-40s. Plenty of rain here.

And if you’re worried about tomato plants getting hurt by chill weather, then put quart-sized Mason jars over them at night.

In my humble opinion, this “gardener” is one In Name Only, and if she took up “gardening” as something she “always wanted to do”, she can’t hold a candle to people who have done it since they were kids.

There are people around here who have market gardens they started at the end of March. They are way ahead of this individual. But it is a hoot to watch when she puffs herself off.

But I like dandelion greens.

Back in the Pleistocene, when I was a kid, mom would have us go pick a mess of dandelion greens, which she’d wilt in bacon grease. If she included bacon pieces, it was almost a meal. YUM!

Today, I wouldn’t pick and eat dandelion greens on a bet. Too many people use herbicides on their lawns.

But when we were kids, no one used weed killers on their lawns and few bothered to fertilize, so the dandelions were… organic, I suppose.

(Sometimes a neighbor would offer a penny per dandelion – must get the root! – to us kids to dig them out of their lawn. So 4 or 5 of us rug rats would converge on the lawn and each of us would dig 8, 10, 12 dandelions each before getting bored. The neighbor got most all the dandelions removed for well under a dollar, maybe 40 or 50 of them, and we got pocket money for penny candy. Win-win.)

The wife and I are quite vocal about replacing manufactured food with species-appropriate edibles. We are also often “consulted” for things the doctors and vets just cannot treat effectively. Note, we do not pass ourselves off as herbalists, health care professionals or even just particularly knowledgeable, but we have helped animals and humans. Our friends and acquaintances consider us more knowledgeable than we claim, so, after hearing about our 100-plus different herbs in the garden, they are always disappointed on their first visit, not to see rolling fields of lavender, or strange, alien-looking trees hanging with anti-cancer fruits. As a matter of fact, they have one, almost universal reaction on seeing our wild, free-for-all, weedy and seemingly unkempt garden. They al walk in, and the first thing they say, goes along the lines of:
“Oh, shame, man, you got dandelions! My daddy used to get rid of them by chalking his lawn, you can get lime from the agricultural blah blah blah blah!”
Dude! You are dissing the most wonderful, the most powerful, the most versatile tool in my entire herbal toolbox! I steal them off other peoples’ lawns, I dig them out on sidewalks, I rip them up from waterways…. once you have learned the power of dandelions, you will never have enough!

So, yeah, all the other climastocrappic nonsense aside, ya’ll should eat a lot more dandelion!

We would dig up the dandelions, making sure we had the whole root. My mother would then wash the roots and roast in the oven. She ground them up as a coffee substitute. It wasn’t until I became an obsessive anti caffeine know -it -all teenager that I discovered that dandelion coffee is very nice.

A book well worth reading is “The Seeds of Change” by Henry or Harry Hobhouse
In it he said how the main reason for the Irish famine was that they didn’t rotate their potato crops. Planting them year in year out in the same fields. The English didn’t help much either though.

California’s Imperial valley is a whole lot hotter than the UK and grows most of the vegetables in the US.

And what about the Great Irish Potatoe Famine?. That was a result of a blight from cold, wet weather. When did anyone ever say Ireland was too hot and dry? I can see it now. People flocking to Ireland to avoid the harsh winters in Spain and Portugal. Not.

The research is a bunch of nonsense.

California’s Imperial Valley is in a geologic trough (the Cahuilla Basin) and is entirely below sea level, like Death Valley which is 240 miles north. Temperatures in the Imperial Valley during summer are in excess of 100°F with a record high of 121°F (49°C) in July, 1995. The Imperial Valley is one of the warmest (hottest) places in the U.S. It’s sweltering.

And yet — wait for it — the Imperial Valley has the most productive ag land in the U.S. Again, for all you who think warm is bad for agriculture, the warmest place in the nation is also the most productive, acre for acre, when it comes to farming.

Warmest = most productive farm land!

Yes, Virginia, the truth is sometimes stranger than fiction, especially when the fiction is perpetrated by alarmunists.

Here are some handy ag facts about the Imperial Valley. And yes, Virginia, they grow lettuce there. A lot of it.

Hat Tip to HR commenting above.

Back in colonial America, particularly in New England, dandelions were salad food. Important, actually. As we all know, dandelions are out early, even when gardens are just getting planted. They are rich in vitamin C, which was very important to the colonials. After a long, hard New England winter eating preserved foodstuffs, scurvy would often rear it’s ugly head. Just in time, fresh greens would appear. No need to comment on how welcome a sight that was.

Back to the Future:
She likes a nice fresh salad.
She:= {She Who Must Be Obeyed.}

Anyway, I examine my salad and find a bowl of weeds. She explains that this is a pre-made salad from the supermarket called “Spring Mix”. None the less, the plants are easily recognized as the same ones that I weed out from around the green beans and tomatoes.
I ask about Iceberg Lettuce for the salads.
Too crunchy, I do not like crunchy

I suggest Romaine Lettuce, it is more leafy.
It still has crunchy bits, I like Spring Mix

Yes Dear, spring Mix is fine, Dear.

Just in case you are wondering, yes, Spring Mix does have dandelions in it. *sigh*

Polk salad is a great suggestion. According to the Food and Agriculture Organization of the United Nations, “ Today, 75 percent of the world’s food is generated from only 12 plants and five animal species.” Yule Gibbons was about 150 plant species ahead of the UN in his knowledge of nutrition. Inspired by Mr. Gibbons (and Tony Joe White) I’d pick polk salad in the Tennessee woods in early spring, fry it up with eggs. Delicious. There are hundreds of tasty, nutritious plants humans could cultivate and thrive on, in any climate condition. The limited experimentation described in this article is cute, and very British, but when people really get hungry, there’s always going to be a Polk Salad Annie to point out where the good eating is.

Reminds me of my father’s definition of expert. X is an unknown quantity and a spurt is a drip under pressure. Potatoes will grow almost anywhere unless in Ireland in the 1850s during the potato blight which provides a strong argument against relying on a single crop.

How do I know this? No scientific basis but I can grow potatoes in my kitchen garden and I’m renowned for within my close family for being able to kill plastic plants.

There is zero evidence that the British weather, either summer or winter is getting ‘to have ‘sunnier summers and warmer, wetter winters’. It continues as changeable as ever. .If you can grow potatoes in hot and sweaty southern China, the ones in Britain are safe for a millenium.

BLIGHT & CROP FAILURE ACROSS EUROPE
1. Notably cold weather July to September. The summer of 1845 (June, July & August) had a mean CET=14.2degC, around a degree below the all-series mean. Specifically, August 1845 was over 2 degC colder than average. This summer was part of a run of poor such seasons from 1843 to 1845, with significantly below average temperatures using the CET series.
2. Persistent / often heavy rains over Ireland accompanied by depressed temperatures during the second half of the summer, precipitated the start of a great famine. The failure was caused by rotting of the potato (a staple food for poor families in the island) in the ground – the weather conditions (cold / damp) being ideal for spread of the spores which caused the Blight. By October of 1845, there had been a total collapse of the Irish potato source.

Hmmm, seems colder wet weather is the driving force behind potato blight.

Does that mean total hours of sunshine from June 21 through September 21? If the sun was above the horizon 12 hours per day for 92 days, that would be a total of 1,104 hours, so the average of about 510 hours of sunshine would be only about 46% of daylight hours. In fact, the ratio of sunny hours to daylight hours is probably less than 46%, since there are more than 12 hours of daylight per day in June through August.

So even during a British summer, the sun is obscured by clouds more than half the daylight hours. Why are these people worried about too much sunshine for their potatoes?

I spent about three winters in England and If I were to live there permanently I would have to take at least one trip to Greece or similar to regain my sanity.
In NZ we can have the odd winters day that is clear and beautiful where the temperature will reach 18c whereas England is constantly gloomy.
When I came back to NZ I ended up having done two winters in a row and I wouldn’t recommend that to anyone.

They’re caught up in the ‘Publish or Perish’ system.
Every now and again they’re given a a ‘prod’ by someone on high.
Told to “Do something or you’ll be defunded” and Climate Change is just soooo good for creating ‘somethings’
Especially for virtue signalling – saying how much you care and how ‘somebody else‘ doesn’t care. ##
Somebody else being of course,#: skeptics, deniers or most deliciously of all, Mr Trump.

<tangent>
## Personally, me myself and I, assert that that is what is wrong in this world right now, Basically, everyone has become mistrustful of everyone else, it makes them anxious & nervous. They soon discover that the simplest way to defuse that angst, to self-medicate so-to-speak, is to ‘go on the attack’
Perfectly sums up Climate Change and surely Shirley, Can Not End Well if it continues.
<end tangent>

Quote (from the article) :”She said that potato blight, a disease which can wipe out the whole crop, is becoming more common because of a warmer climate in this country””

Quote (from a search)” Late blight, also called potato blight, disease of potato and tomato plants that is caused by the water mold Phytophthora infestans. The disease occurs in humid regions with temperatures ranging between 4 and 29 °C (40 and 80 °F). … Potato or tomato plants that are infected may rot within two weeks

“Humid” or “wet” perfectly describes the UK, also “temperatures ranging between 4 and 29 °C”

Thus, Blight and potatoes are a ‘match made in heaven’ in the UK.
If temps do go up (above 29 Celsius), so does the blight problem.
So at least she’s not completely doom & gloom roasting hot, she putting a limit on the thing.

Blight is to potatoes what Influenza is to humans.
No sooner do you imagine you’ve fixed it, vaccinated it, treated it or that it has simply gone away of its own volition, than it mutates into another version.

Except that where Influenza usually takes 12 months to create a new version, potato blight can do it in the timescale mentioned:
i.e. About a fortnight

A crop of spuds in the UK requires fungicidal treatment 4 or 5 times during its growing season – with a different fungicide every single time.
And when the spuds, still underground have reached the desired size or quality, no time is wasted in desiccating/destroying the still green growing tops – so as to try prevent the ingress of the blight.

How do these people, supposedly experts in their field, seem to know so little. About their own field.
Even worse, have no hesitation in displaying their ignorance.
You Know exactly what I’m gonna say next doncha.
I say “Its because they eat sugar = cooked starch – what you get from eating potatoes.

There is actually Good Sense in what they suggest, check out Dandelions and see:

Quote (from a random search query): “They are rich in potassium, magnesium, calcium, iron & copper and also contain vitamins A,B,C & D. … Dandelions also contain more vitamin A and C than most other vegetables and fruit.”

Anyone recall my previous rants and about Soil erosion and micro-nutrient deficiencies?
Look at the list of goodness in Dandelions
There is all the medication you need to help avert:

  • Heart disease
  • Dementia
  • Autism
  • Covid
  • Anaemia

Just add a little bit of Zinc and Vitamin B from somewhere and you have, maybe not a ‘fountain of youth’, more like some Roots of Youth.

There still is a genetic instinct within us,telling us what is and is not good to eat.
Trouble is: ‘scientists’ always know better – via the Publish or Perish doctrine.
Except, every now and again, a little diamond appears from within the mountainous avalanche of rocks, in the shape of a plateful of dandelion leaves.

funny old world innit

Switch off the TV and interweb now and again, have the self confidence & GSOH to experiment with, and trust that instinct.
Be/keep skeptical. It WILL save your life. and that of your children.

Dandelion leaves are quite tasty. I allow them to grow in the garden as a hidden crop for when the SHTF. A couple of the plants are particularly fine specimens that do find themselves added to dinner. Mind you, the rocket is even better (goes well with smoked salmon and a poached egg on butter drenched toast.)Not everyone knows that every part of the dandelion plant is edible. “Climate change” , whatever it actually means caused by increased CO2 gives a better crop for almost all things edible.
Find it hard to believe that potatoes and lettuce will be replaced. If anything, higher atmospheric CO2 will increase the crop, so thin sliced potato with salt and pepper can be added to the breakfast above.

There are varieties of potatoes that will grow in lime sand at 10,000 feet… it is probably the single most universal crop on Earth.

What utter nonsense. Potatoes are grown commercially on near sea level farms in Bundaberg in Queensland (home of the famous Bundaberg Rum) next to sugar cane and pineapple farms, just outside the tropics at 24.8 degrees south. No plausible global warming would cause Britain to experience a Bundaberg climate in the next century.

No rush to grow “small, mustardy root vegetables”

The reason I live where I do is because my ancestors had to flee Ireland because of cold, wet weather, not because of a warming climate…”In 1845 a strain of Phytophthora arrived accidentally from North America, and that same year Ireland had unusually cool moist weather, in which the blight thrived”.

Perhaps I could claim my ancestors were climate refugees.

Talking to UK potato farmers it has been wet winters that have been the problem, not warming climates as for that all they need to do is change the variety of potato they grow.

Nutrient density, anyone?

Beans, peas & potatoes are fairly nutrient dense, as plants go (a potato has more Vit C than a tomato. Whoda thunk it?)…All other veggies are used only for color & texture for the meal. Their content of protein, mins & vt is so scant that you’d need 10-20 servings /d to provide RDA of most nutrients (That’s why USDA recommends 9 servings/d).

Combining 6cu corn + 4cu rice + 1.5cu beans will give you 2000cal and 60gm protein (and a belly ache) for your daily needs…. Six oz of beef will give you 500 cal , 60gm protein and more vits & mins than the rice/corn beans.

Lettuce (or dandelion leaves) ?… You may as well eat paper for the nutritional content.

There was a very clever TV advert for beef in NZ where they had a meat carving dish full of spinach or silverbeet and behind that was a piece of steak on a plate, promoting the iron content, but when the steak was brought forward to match the other it was minscule in comparison.
It really showed how deceptive things can be.

Dandelion is an excellent plant related to lettuce. It is a treat for earthworms and is perfect for salads. It also makes a great natural fertilizer.

I lived in the Middle East for 20 years. Our potatoes were either local or imported from Egypt, Lebanon or India. Last time I looked, these places were somewhat hotter than UK.

Justin Moat (no joke) works in Kew’s Biodiversity Informatics and Spatial Analysis department with the Spatial Analysis and Data Science team – according to their blurb.

Kew went loony with Justin some time ago.

a November 2012 study by Kew Gardens’ researchers revealed that the world’s best coffee strand, Arabica, is likely to disappear by 2080. This is because 99.7% of the growing areas will become unsuitable for the crop

Will coffee disappear from Earth due to global warming & climate change? (coffees.mobi)

I have no problem with jet designers using models because a lot of the variables are known and they eliminate the obvious but the same can’t be said about climate modellers. There are just too many unknown variables. So I think that climate modellers are insane thinking that they have any validity.

@Charles Rotter,
regards the CET temperatures:

https://www.metoffice.gov.uk/hadobs/hadcet/cetml1659on.dat
Last 132 months gliding average minus the previous 132 months gliding average will give you a lag but will also reveal that the gliding 11 year cycle bottomed in 1987, rose 1.1 degrees towards 1999, wiggled sideways until 2008 after which the the gliding average difference has collapsed 1.1 degrees (from a lower top than 1999 to a lower bottom than 1987).

The AMO shows the same thing:
From the anomaly average last 11 year cycle minus previous 11 year cycle bottoming in 1975 at -0.285 increasing to 2006 at 0.283 and falling from there to to -0.00, currently with the normal blip residing at 0.05.

AMO cycle seems to be 67 +/- 1 year and we should bottom out 2043 +/- 2 years. CET cycle seems to be 33 years.

Disregarding the faster reaction on land temperatures than ocean temperatures, they could actually be said to be in sync.

(Average Solar output last 11 years have collapsed to 1905 levels).

All that said, General Winter which got the better of the Germans in 1941-1942, is nowhere to be found in CET data. Hence there must be an overwhelming consensus that the newspapers at the time writing about the terrible cold, were catering to delusionals, climate deniers and ultra-rightwing conspiracy theorists.

Hmmm…. Regarding potato blight, I’m hearing both cold and wet as well as warm and wet being a big factor, so I’m guessing it isn’t temperature, but rather the dampness as the significant factor. There are plenty of other factors as well, and it looks like the Great Irish Potato Famine was somewhat of a ‘perfect storm’ of factors. Among these include that potatoes need “breathing room”, i.e. don’t plant them too close together. Now imagine that you are a poor Irish potato farmer then, with a limited parcel of land. Naturally, you want to squeeze as much production out of that land as possible, so perhaps you plant closer together than you know you should, because usually, it isn’t a problem. Unless blight is around. Rotate your crops. Oops. Don’t leave any potatoes in the ground, and don’t recycle any plants infected with blight. Oops. And so on.

Seeing as you can easily grow all types of lettuce, herbs and even onions in window boxes these people are clearly full of shyt. Though that helps grow things, too! Oh, and the idea that potatoes and yams, which mainly came out of South America, don’t like heat is comical. Insects are the main enemy of potatoes, which, sadly, do increase with warmer temps. So, kill the many varieties of insects that harm them and we are good to go.

Potatoes can’t take the heat? Tell that to all the potato growers in Idaho, which has hot, dry summers!

But if Helena Horton wants to eat dandelion leaves, she can come to my front yard and harvest them for free.

Dandelion leaves? Nothing against them (I’ve tried) and they have a unique flavour but nothing I’ve seen out produces kale. Higher in nutrition and grows way better than lettuce in my climate zone (3 but in reality 2.5). Wind, hail, torrential downpours don’t seem to bother it much. It recovers and keeps producing.

More delusional fantasies by a dip-feces ignoramus who invents absurdities in order to push their personal delusions.

Potatoes are a large varied family.
The historical potato blight was aided by monoculture growing of a very limited highly related subset of potatoes.
Meaning the nimrod in the above article did not bother to read about why the alleged potato blight only harmed Europe.
Nor does she wonder why South America, the original source home to potatoes did not suffer from the blight at all.

So, she invents unnecessary solutions to nonexistent problems because “climate change” temperature changes she cannot detect personally.
