There’s a particular quality to the light in early March in the Forest of Dean. The trees are still bare but there’s warmth in the afternoon sun that wasn’t there a month ago — a brightness that makes you think, wrongly, that the worst is over. You walk the lanes between Lydney and Blakeney and the hedgerows look exhausted. Brown. Flattened by months of rain. And if you know what you’re looking for, you notice what isn’t there yet: no wild garlic pushing through the leaf litter, no hawthorn leaves unfurling, no real green anything except the nettles — stubby, young, barely an inch high — that have been creeping back since February along the damp edges of everything.
This is the hungry gap. And for most of human history in these islands, it wasn’t a gardening inconvenience. It was the most dangerous weeks of the year.
The Cambridge Social History of Britain records it plainly: every year brought “the hungry gap of the late winter and early spring when supplies of vegetables were exhausted, a pattern which was not entirely eradicated in country districts on the eve of the Great War in 1914.” Not eradicated. In 1914. That’s not ancient history. That’s within living memory of people still alive when the Beatles released their first album.
Think about what that actually meant for a family on a smallholding in the Welsh borders or in one of the Forest of Dean villages. By late February the stored root vegetables were mostly gone — soft, sprouting, borderline rotten. The last of the dried beans were at the bottom of the sack. The salt-preserved meat from the autumn pig-killing had been rationed down to almost nothing. There might be some hard cheese. Some oats. And then, for weeks, almost nothing from the ground.
Eighty percent of a rural labourer’s diet in this period was bread — bread and whatever could be scraped together alongside it. One bad harvest, one hard winter, one illness in the family that meant a week of lost wages, and a family that was barely managing tipped into genuine hunger. Historians studying working-class autobiographies from before 1850 found that over a third of writers recalled going hungry as children. A third. This wasn’t exceptional. This was the condition of ordinary life.
And March was where it got worst, because you could see the end coming but you couldn’t reach it. The days were lengthening. The soil was warming. But nothing was ready. Nothing was even close.
Walk those same lanes now in early March and crouch down by the ditch edge. Those stubby green things coming through — that’s your dinner, if you needed it to be. Nettles are one of the first edible plants back every year, appearing in February and running through to June. They’re also, nutritionally, extraordinary: rich in iron, calcium, vitamins A and C, and with a protein content that shames most cultivated vegetables. The plant has been used as food since at least the Bronze Age, recorded by Roman writers, woven into cloth during both World Wars. It is not a quirky foraged novelty. It is one of the oldest food sources in these islands, and it comes back every single year at exactly the moment when everything else has run out.
That’s not coincidence. Or rather, the relationship between people and nettles in March is so old that the word “coincidence” feels almost absurd. Generations of people in these valleys noticed that when the stores were lowest, the nettles came. They built that observation into practice, into recipe, into habit. In Wales and the border counties, nettle soup was a March staple — not because people liked it especially, but because it was there and it was free and it worked. Dandelions too, appearing in February: leaves bitter and mineral-rich, the roots edible, the flowers (when they came, in April) usable for wine. Wild garlic carpeting the damp woodland floors from March onwards. Dock leaves. Cleavers. Hawthorn tips — tender young leaves, tasting faintly of nuts, eaten straight from the hedge by anyone who knew them.
This wasn’t foraging as a weekend leisure activity. It was literacy. The ability to read the hedgerow in March and know what was safe, what was nourishing, and what would hurt you was as basic and necessary as knowing how to start a fire or mend a fence. It was knowledge passed from grandmother to grandchild, refined over centuries, embedded in the landscape itself. Before imported produce was affordable for the masses, wild foods like nettle and seaweed added variety, nutrition and substance to supplement the hungry gap diet — that’s the polite framing. The less polite framing is: without this knowledge, people went hungry in ways that damaged them, stunted their children, shortened their lives.
We fixed the hungry gap. That’s genuinely worth saying without irony or nostalgia. Refrigeration, global supply chains, industrial agriculture, supermarkets open at seven in the morning with Peruvian asparagus and Kenyan green beans available in February — we solved the problem that had been killing and diminishing people in these valleys every March for thousands of years. That is an achievement. The hungry gap, in its original brutal form, is gone for most people in Britain.
But something else went with it. The hedgerow literacy — gone, mostly. The ability to look at a ditch in March and see dinner rather than weeds — gone. The knowledge of which plants come back first, what they taste like, what they do for a body depleted by months of restricted diet — gone, or nearly so, or retreating into a small community of foragers and herbalists who carry it forward against the current.
Here’s the thing that bothers me about that. The knowledge didn’t just tell you what to eat. It told you where you were in the year. It gave you a relationship to the land that was granular and immediate — not “it’s spring” in the abstract, but “the nettles are back by the stream, which means it’s that particular moment, which means certain other things will follow.” Strip that out and replace it with a supermarket, and you lose a form of temporal awareness, of place-awareness, that no amount of time spent in nature quite replicates if you don’t know what you’re looking at.
I notice this in myself. I can walk the same lane I’ve walked a hundred times and not really see what’s happening in the hedgerow unless I slow down and look deliberately, with intent. The default setting — the setting that’s been installed by living in a world of continuous food availability — is to look past it. To see scenery rather than larder. The old default was the opposite: to scan constantly, to notice what had appeared since yesterday, to read the season through what the plants were doing.
There’s an argument — and it’s not a stupid one — that we can recover some of this through technology. Apps like iNaturalist and PlantNet can identify a plant from a photograph with remarkable accuracy. You crouch by a ditch, photograph the stubby green things, and your phone tells you within seconds: stinging nettle, Urtica dioica, edible, here’s how to prepare it. The knowledge that took generations to transmit can be accessed in ten seconds by anyone with a smartphone. That’s genuinely democratising. I use these apps. They’ve taught me things about the plants in my own local patch that I wouldn’t have known otherwise.
But there’s a gap between the app and the knowledge, and it’s worth being honest about what it is. The app can identify. It can’t tell you that the nettles by this particular ditch come through two weeks before the ones on the other side of the lane because of the aspect and the drainage. It can’t give you the bodily knowledge — the feel of where to look, when to look, what the signs are — that comes from doing this seasonally for years, or from being taught by someone who did it for years. It can’t give you the relationship. What it can do is get you started. It can lower the barrier of entry into a practice that requires, ultimately, time and repetition and direct encounter with specific places.
The Woodland Trust’s foraging guides for March read like entry points into a different way of seeing. Nettles, dandelions, wild garlic, goosegrass. All free, all nutritious, all appearing now. The guides are good — practical, safe, honest about what to avoid. But they work best as a beginning, not an end. They’re a door. The knowledge is on the other side of it, and it’s built by walking through the same door repeatedly, in different Marches, in the same places, watching what happens.
There’s a harder version of this argument that I keep coming back to. We engineered our way out of the hungry gap using global supply chains that are, it turns out, not entirely reliable. The 2020 empty shelves. The 2022 energy price shock that made heating and eating compete with each other for millions of people in Britain. The Trussell Trust reporting that demand at food banks had more than doubled during the pandemic, UNICEF — for the first time in its history — funding charities to feed hungry children in the United Kingdom.
The hungry gap didn’t go away. It changed shape. It moved from being a problem of seasonal scarcity to being a problem of economic exclusion. And the hedgerow knowledge that helped people survive the old version of it has been almost entirely lost, which means one of the oldest, most local, most resilient food systems we ever had is now invisible to most of the people who live closest to it.
It’s March. The nettles are back. They were there for every hungry March before this one, and they’ll be there for every one after. Start there.

Practical note: Nettles for eating should be picked young — the top four to six leaves only — before the plant flowers. Wear gloves. Wash well. Blanch in boiling water for two minutes and the sting is completely neutralised. They taste somewhere between spinach and cabbage, earthy and substantial. Nettle soup with potato and a little cream is one of the best things you can eat in March, and it costs you a walk and a pair of kitchen gloves.
