If I had to nominate the most frustrating and dangerous time of year for the unwary gardener it would be right now. I’m too embarrassed to photograph the overwintering broad beans which, after a week of interminable sub zero temperatures and scything east winds look more dead than alive. When a freeze lasts so long, no amount of protection seems enough to prevent the slow destruction of cell walls. Even the garlic looks a bit sad. To think we were praying for a good cold spell to spur it into growth a few weeks ago! It would be all too easy to welcome this weather as a return to a traditional winter season – but it’s not. Everything about the weather has been excessive these past twelve months; wettest, dryest, hottest, coldest, stormiest. It rather reminds me of my community work days when we dreaded the autumn magic mushroom season because mixed with cheap cider the effect on our young people was to make them completely and sometimes violently unpredictable. Anyway, that’s enough about the government let’s get back to gardening.
Climate change is happening fast and so, exactly like covid, there’s no point in sitting around waiting for things to get back to normal because whatever normal might turn out to be it won’t be our normal. I suppose if you drive to work in an office or live in the centre of a city you might not notice these things unless you garden ; but we live bang in the centre of a city; a jewel of the West Country tourist trade that just happens to be at the same latitude as – let’s say Newfoundland, parts of Russia and Norway and Canada; thank you so much Gulfstream. However when the jetstream takes it upon itself to holiday 1000 miles south of where it normally does, the weather comes with it, and if the North Atlantic Subtropical Gyre decided to follow suit we would all be in deep doodoos – probably penguin doodoos!
Even under the old dispensation February could throw up several gloriously balmy days followed by a freeze, and we’ve moved our last frost date into the second week of May after some bad experiences with the grapevines. “Cast not a clout ’till may be out” refers to the (Crataegus) blossom not the month; and for the ultra cautious gardener it’s still good advice. But – as it seems as if we’re going to have to get used to these extreme and unexpected outliers in the weather. Last year many of our neighbours lost their potatoes in a late frost on May 12th, when we also lost some borlotti and runner beans when their fleece blew off. We must think seriously about plant protection for extreme wind and cold; and increasing water storage for drought.
However that won’t be enough, and we’ll also need to expend some serious thought towards changing the plant varieties we grow and breeding some better ones if we can. Here at the Potwell Inn we’ve taken on all three challenges by building a polytunnel, which will be finished tomorrow if the forecast holds up. We’ll increase our water storage by building a sloping roof on the compost bins and harvesting rainwater from it ; but it turns out that one source of excellent advice on new varieties and techniques for a more extreme climate comes from across the Atlantic in the USA, because it’s a country with an enormous range of climates.
The US is some way ahead of us, not just in organic and permaculture techniques but also in publishing books about it – hats off to Chelsea Green – and I’ve been feasting on some really compelling ideas. Winston Churchill once described our relationship with the US as “two nations divided by a common language” – and it’s absolutely true to say that I’ve needed to be really careful about making assumptions while I’m reading. Cultural differences matter and today I realised that our only experience of corn is of growing sweetcorn. I don’t think I’ve ever given a moment’s thought to growing corn to store for the winter as a source of carbohydrate. This is the time of year, as winter comes to an end, when we realize how small our stored food supply has become. Lunch today was a fabulous bean soup which has become an indispensable staple; but our only home grown contribution was the herbs and some tomato passata. We have just 200 square metres of growing space – which is far too little to be self sufficient in vegetables. John Jeavons suggests it would take around 8000 square feet to feed two people and that’s eight standard British allotments worth. We’ve got just the one, so our ambitions need to match our land. That’s not to say we shouldn’t garden our space as efficiently as possible, but it would be silly to beat ourselves up because we still have to buy some veg. Our take on this is to grow the things we love that are most expensive to buy.
Suddenly food preservation and storage has come on to the agenda as we begin to realize the sheer fragility of the food supply. In the past, our experiences of food shortages have been very temporary, but in the UK some shortages have been ‘baked into’ our disrupted supply chains. This isn’t entirely down to trade deals, it’s also about industrial farming and food production. When it takes ten calories of fuel to produce one calorie of nutritional value, at a time when oil production is trapped between the twin pressures of ever higher extraction costs and anti pollution legislation; something is going to break and it will boil down to a choice between changing our ways or breaking something we really can’t repair. As civilizations and epochs go, the anthropocene is more like a dragonfly – a long time developing and then very quickly spent.
Anyway, to get back to practicalities we’ve washed and sterilised all our pots and modules and started the propagators. Early sowings – replacement broad beans for instance! – are underway, and with the polytunnel on the brink of being finished, we think we can gamble against even the most inclement weather and get the chillies, aubergines, peppers and tomatoes started. I also think now, in the light of my recent reading, that the three sisters planting needs to be understood and honoured within its cultural context and not treated as a horticultural novelty; and that will need to happen in the kitchen as well as on the allotment. I’ve always wondered what on earth ‘grits’ are and how you might eat them! We have no idea whether borlotti will grow up the corn stalks, and we’ve also tried to dry and prepare the seeds from our winter squashes, and it’s clear that we have a great deal to learn.
It’d been the most tremendous week. We defied the weather and worked on the polytunnel every day until our fingers froze. It was always going to be a challenge because it fitted the available space – let’s say – snugly; or more honestly, down to the millimeter. I’ve learned a whole lot of things about building these structures including the fact that angle grinders don’t like aluminium, and filling up your metal measuring tape with mud is a bad idea because all the markings fall off. But in the unlikely event that we ever build another one, we’ll do it in half the time! The next challenge is to recalculate all our sowing times to make the best ue of the new tunnel. I foresee several frank exchanges of views as my Tiggerish instincts collide with Madame’s Eeyore. In matters of germination temperature settings in the propagators, (in Flan O’Brien’s terms), I’m definitely a full throttle man. Madame thinks only of the fireman
