I know, it makes me feel a bit premature too, since we’re probably about to break the record for the wettest February since records began – but if climate change means anything at all it’s the fact that our weather is becoming less and less predictable. The swings are wilder; feast and famine come together in the weather cycle and ironic though it might seem, we’re investing heavily in water storage at the moment at the Potwell Inn because it’s raining. Starting to wonder what to do after it’s been dry for six weeks and the government is planning a hosepipe ban will be too late. We’ve been storing 1000 litres for a year and I’ve been busy planning and building a new storage layout, connecting the butts and increasing our capacity to 1250 Litres immediately and later perhaps adding another 500 Litres to take the water running off the compost storage bins. It seems all wrong to use pure drinking water for the allotment, but for the most part we’re all very inexperienced when it comes to efficient watering. I’m quite sure we water too much – in my case because I actually enjoy it on a summer evening – but much of it will be wasted. So one of our climate change lessons for the next few years is to learn how to water just enough and not too much.
We’ll also need to be looking at the plants we grow; the varieties that work and a whole range of new horticultural skills. There will be things that can’t survive the new weather regime and I’m sure the seed catalogues will be offering lots of expensive new varieties. On the other hand, open pollinated varieties using the best seed gathered on our own allotment year on year might do even better. I’ve read that it’s surprising how quickly adaptations happen. There’s a good case for looking again at some of the trad varieties that could bring useful genes into play. I once had a micro-variety of cherry tomato that had been treasured since the war by a retired firefighter. It had no name – just ‘Tim’s tomatoes’ and the fruit was absolutely delicious. Sadly they died with him but whatever they were, they loved life exactly the way Tim grew them.
There are so many things we can do as growers to mitigate climate change. That’s not an excuse for not doing all the things we know about in our personal lives, the way we shop and travel and dress. But change, when it comes, will come slowly and we need to prepare for the extremes in the meantime. We’ve done some trials with windbreaks and frostbreaks (hardly needed this winter); I’ve written often about drainage and improving soil condition – all these things can add resilience to an allotment. Our allotment is sheltered from the prevailing southwesterly winds by a line of tall trees, but the northwesterlies, northerlies and northeasterlies can be incredibly cold and destructive and so we’ve put all our structures – greenhouse, shed and compost bins on the North side, and we’ve built a strong windbreak to the east. We’re not allowed to have fences or hedges but there’s nothing in the rules about training vines and growing vigorous soft fruit along wires.
The hotbed, although it’s quite small has also given us flexibility during the early months of the year. It’s surprising what you can grow on 12 square feet of fertile soil, kept at a steady 20C. Climate change is a real challenge, but it’s one we can rise to. I’ve just spent the happiest couple of days sourcing exactly the right kinds of pipes and connectors and one additional water butt that fell into my hands when I walked into a local garden centre and saw the very thing I was looking for next to the till waiting to be returned to the wholesaler. I did a deal with the boss on the spot and got it at a reduced price. So that’s in the back of the car along with a pile of connectors and pipes that I can’t wait to assemble. For the first time we’ll have a free (OK it cost a bit) but a sustainable source of rainwater that flows freely to a convenient tap at watering can height. It’s been a logistical challenge but by a bit of judicious juggling I’ll have preserved all bar a couple of gallons of the water that we’d already stored. I can’t tell you how much I’ve enjoyed it. That’s one bit of infrastructure to cross off the list, and then I’ll turn to putting a roof over the compost bins and harvesting the rain off another 60 square feet. Further down the line I want to try out an idea for solar heating using an old radiator that I saw at the Centre for Alternative Technology at Machynlleth years ago and I might even have a go at an irrigation scheme run off a 12V battery and a solar panel on the shed, used to operate a solenoid valve and ……….
Madame gets exhausted by my enthusiasms so I’d better shut up. The flat is full of seedlings. Greta Thunberg came to Bristol today. Bristol – for the benefit of the political commentariat who never leave London (the Great Wen as William Cobbett would have it) – Bristol is a large city near the confluence of the Wye, the Severn and the Bristol Avon where people speak with a funny accent and around which the electrification of the railway was diverted because too many people voted Labour. George Ferguson the previous Mayor was very involved in Green Politics and the present Labour Mayor has continued in the same vein. There were about 30,000 people there at the demonstration and the march passed off completely peacefully as everyone except the police and the media expected. The local evening news reported that ‘thousands’ of demonstrators turned up and probably by 10.00 pm the BBC will be reporting that ‘quite a few’ people came and ruined the grass on College Green. It’s a good job, then, that these wicked demonstrators have already started raising money to repair the damage to the grass caused by 30,000 pairs of feet. Meanwhile the police were busy filming these nascent terrorists – some of them at primary school – are we living in la la land?
