So after the philosophical tone of the last couple of posts, I thought I’d share an anxiety free photo of a wheelbarrow. There’s not much going on at the allotments at the moment – mostly the site is like the Marie Celeste; full of signs of occupation but devoid – apart from the diehards – of human company; no gossip to be had.
There are two especially dangerous moments for new allotmenteers – six months apart but equally fatal to the morale. In July the early optimism of cleared ground and early sown crops gives way to an explosion of weeds – especially on newly won ground. In December, once the pruning is done and any bare earth covered or mulched, the cold and often grey, greasy weather is a powerful disincentive to gardening. These days, knowing what we do about air pollution, it’s even difficult to justify the bonfire – the old friend of bored allotmenteers on winter days.
But composting goes on whatever the month, and with time on our hands it’s the perfect opportunity for clearing up, leaving lots of habitat for overwintering insects; any bits of civil engineering that have been on the “to do” list for several seasons and, if you’re lucky like us, starting next season’s leaf mould. I remember many years ago buying one of Christopher Lloyd’s books – I think it was The Well Tempered Garden – and becoming increasingly dismayed that his idea of a small garden was about the size of three football fields, complete with mature trees and an abundance of compostable materials. For the vast majority of us, the materials available for composting are extremely limited.
However, our local authority, in a bid to save money, has now built a number of gigantic bunkers on various allotment sites around Bath in order to save the cost (I can hardly believe this!) of dumping leaves. Obviously we’re delighted but slightly overwhelmed with this generosity. Added to regular supplies of free wood chip they’re a blessing and in the past they disappeared almost as fast as they arrived. Possibly not so any more.
Leaves are a threefold blessing, as well as being – for different reasons and in different phases – biochemical miracles. As green leaves attached to their trees they convert sunlight and water into sugar and, with the aid of countless fungal networks and bacteria, swap sugar for micronutrients in ways we’re only just beginning to understand; storing carbon in the soil at the same time. As fallen leaves they make a perfect mulch for soft fruit bushes and empty plots. We once covered a patch of cleared ground with six inches of leaves and threw a cover over them. When winter was over we removed the cover to find that they’d all but disappeared due to the actions of worms..
But stacked in one of our compost bins – ours will accommodate ten bags similar to the one in the photo (just big enough to be able to lift and empty when full)- and through the action of moulds, fungi, bacteria and the whole gamut of leaf eating insects they slowly decompose. By March the heap will have shrunk by around a third and we’ll cap it with six inches of compost to grow a prolific crop of ridge cucumbers whose roots reach deep into the moisture holding leaf mould.
Then in a final act of beneficence the finished leaf mould will be mixed 50:50 with our own compost which will be spread on our plot in the autumn when the whole cycle starts again. I suppose in a perfect world the leaves would be left to rot where they fall, but we try to accomplish the same thing whilst growing food – which brings me to an excellent article in today’s Guardian which reports on a new piece of research that supports the idea that allotments can make a substantial contribution to food security and local (ie low carbon footprint) sustainable food networks. If only forward thinking local authorities would take up the challenge and secure leases on plots of suitable land surrounding villages, towns and cities, the waiting lists (thousands in some cases) could be reduced and a secure supply of wholesome, mainly organic food could be in place within a couple of seasons.
