Fertility. Plotlines series 2: sustainable gardening on your allotment

Seedling emerging from healthy soil

The difference between spindly pest ridden crops and strong vigorous productive ones lies in the quality of your soil, the micro-organisms and trace elements in it and the plants’ ability to take up nutrients. So as previous episodes of Plotlines have emphasised, tending your soil and making abundant compost on your plot are absolutely essential to good growing. That also, of course, means more nutrients available in your crops for your own good health; so much food grown with chemicals lacks essential minerals (not to mention so called food that is processed in a factory and not grown at all).

Some gardeners are happy to use manure believing it will ‘enrich’ their allotment land. (It’s worth remembering that by the time it has sat in a heap on your allotment site for a few weeks most of the nutrients will have washed down into the ground – old manure sites grow fab nettles as a result!) What manure offers is nitrogen, which is helpful for leafy crops, less so for fruiting ones like courgettes and beans and squash. And of course it comes from animals, which you may want to avoid in your food cycle; after all, what have they (usually cattle or horses) been fed? How have they been cared for? What antibiotics or other drugs have they been given? Are they farmed organically? Many farm animals are regularly dosed with vermicides, for instance, to kill off any worms in their guts. So if you spread contaminated manure on your land, bang go your precious worms! Or a herbicide, aminopyralid, may have been used on their feeds and be present still in the manure so when you apply it you are killing growing plants on your plot. The same is true of clopyralid which is in lawn weedkillers and may be present in municipal ‘green’ waste. Traces of such drugs can well linger – neither your allotment association nor the farmer is going to be testing to be able to reassure you there is no residue. A better bet might be to use bedding from pet animals that are vegetarian, like guinea pigs and rabbits bedded on straw; ask around……

You can get very scientific about your food growing and work out the nitrogen, potassium and phosphorus needs of different crops and their availability in your soil. But really all you need to do is practise good organic cultivation, by composting using readily available materials like household kitchen waste, fallen leaves, dilute urine, unprinted brown cardboard, wood ash, annual weeds, straw, grass cuttings, leafy prunings and hedge and tree shreddings. Seaweed is a wonderful addition, but we’re forty miles from the coast here and it’s not legal to remove seaweed from the Crown lands which are our foreshores. Composting is a biological process so heat is not vital unless you want to speed things up or kill weed seeds.

Other good allotment sources of fertility include using green manures, especially quick growing flowering crops which will also attract pollinators, making liquid feeds from comfrey (the wonder plant) and nettles, and mulching crops so nutrients aren’t washed away and the soil is protected. Biodynamic gardeners use a variety of preparations, which you can make rather than buy, using herbs you may already be cultivating. You can find out, too, which plants complement each other’s growing; the classic example is beans, squash and corn, although the success of that trio does depend on the weather and subsequent timings. But you can learn to plant in guilds, as companion plantings: groups of crops that favour each other and provide a miniature eco-system, providing nutrients, out competing weeds and keeping pests at bay. Good productive food growing is a holistic sympathetic process that you as the gardener gently coax into being and learn from.

Important – Avian flu update

Hens in an allotment

As of Monday 27th January, York is in the new Avian Influenza Prevention Zone (AIPZ).

This means that all allotment holders who keep birds must keep them housed to protect them from bird flu. Please follow the guidance here to make sure you are complying with the housing and biosecurity measures to keep your birds safe and prevent further outbreaks.

Permaculture. Plotlines series 2: sustainable gardening on your allotment

A permaculture garden

Permaculture

Wade Muggleton’s back garden, shown in the picture above, has been designed using permaculture principles. He collects rainwater, uses vertical space for growing food to get the most out of his garden and incorporates a wide range of plants and varieties.

The basic key principles of permaculture are probably the best place to begin to appreciate what it’s all about; it’s from those ethical principles that the twelve design practices are developed. It’s not just a way of gardening holistically with ecological sensibility, it’s a system of permanent cultures for sustainable living. There are just three principles, which are themselves common to so many philosophies and peoples over the world, but grounded in practicalities – and they seem to align quite closely with elements of allotment practice:

  • Earth care
  • People care
  • Fair shares

Earth care

Care for the earth means observing and reducing the impact of our activities; a third of our ecological footprint derives from food, so of course it makes sense to grow as much as we can ourselves, which is the fundamental basis of allotmenting. At the same time we look to nurture and encourage a rich biodiversity above ground and below, to recognise webs of life and what can grow around us. So many of our sites are hugely valuable habitat with extensive tree and hedge margins, within urban settings.

Permaculture design uses nature’s own principles, of diversity, zones, complexity, layers and relationships among plants, humans and other creatures. Many allotments reflect that diversity – even if individual plots are sometimes regimented and bare, others are richly abundant, so that the mosaic of sites, and then the bigger picture of all our city wide sites together, make a valuable contribution to caring for the earth. Time was, allotmenteers used chemical fertilisers and pesticides and regularly burned their prunings; happily most have recognised the appalling damage those practices cause and YACIO tenancy agreements reflect that better.

People care

People care is basically about the power of community, which is so vividly present across and within our allotment sites. We have to get on with our neighbours – even when we disagree with their choice of cultivation practices! Most sites have generous informal systems of sharing: produce, knowledge, tools, time, seeds…..a gift exchange that sustains and forms bonds.

Our allotment movement has got better in recent years at responding to the different needs of different people, which is another expression of people care, asserting equity in the right to the benefits of growing your own food. We could do better still to establish caring relationships with our wider community, like growing for neighbourhoods, teaching skills and donating produce to food banks.

Fair shares

The history of the allotment movement in Britain is closely aligned with the idea of common people having a share of the wealth of land, after the Enclosures of the seventeenth, eighteenth and nineteenth centuries took away access to local land for cultivation. The General Inclosure Act 1845 made rudimentary allotment provision for the ‘labouring poor’ mandatory – but it was not common land and remained part of the feudal hierarchy that still pertains in our county now. But a social movement gathered momentum and eventually (crazily concise summary this!) in 1922 the Allotment Act made provision available to all ‘where a need was shown to exist’. But there was never that sense of a right to ‘fair shares’ of access to land which characterises permaculture.

But we also need to recognise fair shares at the non local level. The industrial growth model is shaped to ensure some are winners and most are losers with no respect for the exploitation of people and the earth’s resources. So permaculture ethics invites us to look at our own consumption patterns in the broader context: what is the embodied energy involved in buying new tools, or new timber for some classy raised beds?

Our allotments can be a manifestation of these key ethical principles. A new year, a new resolution to live and grow more sustainably.

Plotlines series 2: sustainable gardening on your allotment – Tools

Old mattock and wooden handled garden tool

Do you love a gadget or a new bit of kit? Or are you using your parents’ old tools, or some you picked up second hand? There is a range of choices and decisions to be made between those options, but if you’re committed to low carbon, sustainable gardening on your plot then you need to think carefully about how and what you choose to use.

Of course, there are gardeners whose injuries or disabilities or age mean they need to use power tools for ease, efficiency and comfort. And if you have a long hedge and not much time you may need to use an electric hedge trimmer, once a year. But there are many occasions when plot holders are using expensive powered tools unnecessarily. Expensive not only because they cost a lot of money, but because they cost a lot of carbon. Your battery charged strimmer may claim to be ‘no emissions’ – but that is wholly disingenuous. The embodied carbon that is involved in mining the materials, transporting them to a factory, using high temperature high energy processes in their manufacture, then shipping them to where you probably drive to shop, is highly significant. And what of the labour conditions for the people involved in acquiring those raw materials or working in those factories?

A more sustainable option is for allotment sites to run tool libraries where you can borrow a power tool occasionally without having to own it. Or to borrow and share among your plot neighbours. The same is true of ladders that tend only to be used at harvest and pruning times of year. If you think you need a strimmer or a mower for the grass on your plot, then maybe you’ve got too much grass anyway and could convert some of that area for cultivation. And really, who needs a blower for leaves when you can meditatively rake and gather them to make your precious leaf mould?

Maybe you’re paying for an expensive gym membership as well! How about being active on your plot, using hand tools that work out your arm and leg and core muscles? Cutting a hedge, or even small areas of grass, with a pair of shears is not such hard work and encourages careful management of the hedge for wildlife rather than reckless speedy demolition; learning to scythe or using a Chillington ‘slasher’ to keep down the nettles once the butterflies have pupated is easy and pleasing when you find the rhythm of the action.

This is a good time of year to spend some time looking after your precious tools: cleaning and sharpening blades and cutting edges prolongs their life and enhances their effectiveness. Putting tools away dirty is never a good idea anyway! Clean wooden handles and lightly oil them so they don’t crack or split. If a handle breaks, you can usually replace it without having to replace the whole tool. Ash wood is lovely to use and grows smoother as it ages (although if you struggle with sore shoulders you might want to choose lighter aluminium handled tools.) Learning to use a sharpening stone is very satisfying and improves the ease of tool use considerably. Good quality secateurs will have the option to replace worn or damaged blades without chucking the whole thing out and buying new.

So what is your favourite tool to use? The mattock pictured above has so many varied uses, as a hoe, for trenching and earthing up potatoes, for cutting through wild edges when seeds have set, for loosening the surface of soil before planting.

Plotlines series 2: sustainable gardening on your allotment – Seeds

Packets of seeds

Does it seem an odd time of year to be thinking about seeds? Isn’t that a spring thing? In fact, now is a great time of year to do two seed related activities: save seeds from your harvested crops, and make a realistic list of seeds you will need for the next season, while this season with all its flaws and glories is still fresh in your mind.

So, what grew well, what didn’t (and was that because of your neglect or error of timing, or the weather and the slugs?), what did you enjoy and what wasn’t so popular? What crops did you covet that your plot neighbours were growing? What didn’t you have enough of, or annoyingly forgot about altogether?

There are some important considerations that you might like to dwell on now you have a bit more time. When it comes to buying seed, if you go for a F1 hybrid with allegedly enhanced qualities (straightness, uniformity, easy to pick) you’re spending extra money on summat the big, international seed companies and commercial growers get the profit on. And you can’t save seed from those varieties – it may well be sterile and if it’s not, it won’t come true. Basically, using those seeds takes control out of the small growers’ hands and favours industrial scale production. Not allotmenteers.  And of course it’s in the big international seed companies’ interest to get you buying so called ‘fresh’ seed every year. Local strains have been lost in the last fifty years or so, but we can choose reputable open pollinated seeds from small ethical companies trading in ‘real’ seeds, save and swap our own seeds to perpetuate varieties that have done well on local sites, and be part of millennia of caring for plants and the land.

So how do we save seed? There is still time this season to harvest and dry and keep seeds from many of your favourite crops. It’s a good idea to tie a bit of twine around plants that have done well or given you a tasty crop, so you can identify them as to be saved for seed rather than eaten. Peas and beans are really easy ones to start with: let them mature and dry on the plant, turning dark drown, dry & wrinkled. Then pick and shell them out and make sure they are completely dry before storing somewhere cool and dry. If it’s a wet season, pick them and dry them on a window sill or on your greenhouse staging. On an allotment scale you don’t really need to do much more than that. Except remember to label them!

It’s also easy to save seeds from the brassica family: salad crops, kales, cabbages, radishes etc will all make seed pods after they have flowered – so you have to be patient to wait for that stage of development. The pods can then be dried and shelled out, and you can even take a short cut by just shaking a few dry plants out over a hoed and raked bed, where they will likely germinate readily. Lazy/patient growers may even find plants self sowing – which is to say they drop their seed near the parent crop, giving you a little forest of seedlings to plant out, share and give away, or eat as trendy ‘microgreens’ in salad.

One other plant is worth specifically mentioning in relation to seed saving: parsnips. Notoriously tricky to get to germinate, using fresh seed saved from a plant you let flower and go to seed is far more successful. Many seeds can be stored for years, but not parsnips. Parsnip flowers are tall and elegant (a member of the Apiacae family) and as their family name suggests, hugely attractive to pollinating insects. Let the seeds dry on the plant and then harvest them into dry brown paper bags, label and store. The same system works well for many flowers on your plot too: calendula, hollyhock, foxglove, feverfew and others.

Happy harvesting……

Plotlines series 2: sustainable gardening on your allotment – Soil

a gardener holding a handful of soil

The showy time on the allotment is over; it may have been a good season for you, or it may have been a disappointment, with slugageddon and drought stressing you and your crops. There’s still top fruit to pick, still some beans and corn and squash, and hopefully you’ve got plenty of winter crops growing steadily to see you through the dark months. But it’s time to get on with the real work and what really matters – and what will make a huge difference to your showy tasty crops next season. The soil. Are you taking it for granted? Disrespectfully calling it ‘dirt’?  The web of soil life underpins all life on earth and our responsibility as plot holders is to nurture that soil life in every way we can.

In a teaspoonful of healthy soil there are up to 5 billion anaerobic archaea and aerobic bacteria, over 1 million protozoans, thousands of nematodes, hundreds of microarthopods and around a kilometre of fungal hyphae. So what? Here’s why: together they create plant growth substances, they fix carbon and nitrogen cycles and make nutrients available to plants. And you thought you were doing all the hard work! Actually, it’s this world under your feet that sustains growth and life on earth. And every time the soil is disturbed, or artificial fertilisers and pesticides are applied, soil life is killed and soil structure compromised. Then we get soil erosion, water and nutrients are leached out, and pests and diseases follow.

If your plants look stressed – wilted, yellowing leaves, infection or insects eating away at them – then it’s likely that your soil life is depleted. In other words, you’re not providing enough nutrition for the bacteria and fungi. That soil food comes, in part, as you no doubt already know, from regular addition of home-made compost as a mulch, which provides the carbon sugars that are needed.

So the key activity at this time of year is to make sure your soil is not bare. There are various ways we can do that. Now we’ve had some rain, and the soil is still warm, sow some fast green manures. Don’t choose ones that are deep rooted (tares, alfalfa, rye grass, field beans) as you’ll have to dig them in next spring, which disturbs your soil structure; phacelia, clovers and mustards are all ideal over the next month. Spread your compost over the surface of other beds as you clear them. Or just cut down beans and peas and leave the roots in the ground to help fix nitrogen for brassica crops next spring, and cover the cut down foliage with big sheets of brown cardboard. And make compost. Gather as much material as you can: annual weeds, nettle and comfrey tops, soft prunings, torn up cardboard, your neighbours’ lawn mowings, food waste, rotten apples and pears….as much as you can get hold of.

And let’s not forget this: the parallels between soil and human health are too obvious to ignore. In the same way that those bacteria and fungi and archaea promote and protect soil health, so the beneficial microbial flora in our guts (our microbiome) are essential for promoting and protecting our digestive health, and our immune system. Soil is the source of life and health so use the autumn months to look after the earth on your plot.

Plotlines series 2: sustainable gardening on your allotment – Harvest

Plums on tree ready to harvest

The beginning of August marks the festival of Lammas (or Lughnasadh in Celtic), the time of harvest. You will likely already have harvested some crops: have lifted the early potatoes, and maybe the main crop too if the endless damp weeks brought blight to your plot; be regularly picking courgettes and peas, while the broad beans are over and the French and runner beans just starting. And salads should be something you can crop any day of the year with some careful planning. You’ll be making sure winter crops of brassicas and leeks and roots are well protected from their various pests, anticipating harvest still to come. Top fruits like apples and pears are still to come too, while plums and blackberries are just starting to be ripe and ready. It’s also time to prune plums, gages, damsons and cherries – the prunus family; if you delay after September and the equinox (Mabon), then you risk getting silver leaf fungal disease which will eventually destroy the whole tree. So for everything, prune in a timely manner at all times!

This is also traditionally one of the turning points of the year: there’s no denying the shortening days and lengthening nights. Growth is slowing down but we are at a time of abundance, hoping to gather and store and preserve what we can for the coming winter. That abundance may also mean you’re able to share what you can’t use yourself, giving harvest gifts to local neighbours or food banks, and perhaps receiving gifts of crops you don’t grow from fellow allotmenteers. We can be self sufficient and generous, cooperative sharers at the same time.

Lammas is traditionally the time of grain harvest, which is the foundation of our diet: the wheat, oats and barley. While you’re unlikely to be growing those on your plot, nonetheless you’ll be aware of them growing on the industrial-agricultural outskirts of York. Significantly, grains are also the seeds of future crops. But every fruit also contains the seed of new life, so part of our harvest celebrations can be to save seed from successful crops for the next season. As your sweet peas, nasturtiums, beans and peas ripen, gather the seed pods, dry them carefully somewhere warm and dry, and label packets of them to be stored ready for spring. You can also easily save seeds from courgettes, squashes and pumpkins, and if you leave a few favourite lettuces, cresses, rockets and kales to go to seed, you can save them too – or they may even sow themselves on any bare ground around the plant. So the cycle of life and cycle of growing continue through the narrative of our gardening.

You might also want to reflect on harvest more broadly: how did plans earlier in the year come to fruition or get pushed off course? What seeds do you want to sow for next year, literally or metaphorically? Celebrate whatever your harvest and keep your intentions viable for another year.

Sustainable gardening on your allotment – fruit on your plot

Redcurrants

Gorgeous jewels of deliciousness are coming ripe and ready now – red and black and white currants, raspberries, blueberries, dessert and culinary gooseberries, strawberries, hybrid josta and Worcester berries – but if you want to enjoy your soft fruit you’ll need to deprive the birds of that delight. Red fruits are more attractive to birds, but that doesn’t mean your blackcurrants, blueberries and gooseberries are safe at all (though the yellow raspberries do seem to be fairly immune); gooseberries tend to ripen first of the soft fruits and are a real favourite of the pigeons – and they’ve got big bellies! Netting fruit is a tedious job, but a very necessary one, and a real art. You need to make sure it’s weighted down at ground level, that you sew up any holes (nets can be used for decades if you look after them – just as well as the majority are still plastic based), and that there are no gaps where you overlap net on net. Try to have the nets like a cage around your bushes; if the net is just draped over them, birds will happily perch on top and have a feast through the holes. And while keeping the birds out is the main aim, you need to be careful that a bird can’t get in and get stuck and tangled in the net; however vindictive you may feel about pigeons, it’s very distressing for them, and for you, to have a struggle and possible death on your plot. 

Netting cherries is a harder job as the mature trees are quite large; a good tip is to use net bags that your seed potatoes might have come in, or onions and carrots bought in bulk; you can slip these onto a branch like a sleeve and tie it on. Blackbirds adore cherries: if you don’t net them, you won’t get them.

Soft fruit are a really worthwhile part of your plot patchwork of crops. There’s no need to water them unless in a very dry year; if you have weeded and mulched effectively around them earlier in the year, there should be plenty of moisture deep down where the roots can find it, especially after the very wet start to the year we have had. Currants and berries are expensive to buy in shops and inevitably not as fresh as those you grow yourself and pick regularly and frequently. When fruit ages, even a matter of a day, it loses its valuable vitamin C and the antioxidant polyphenol constituents diminish. You can easily pick and freeze your produce to give winter meals a bright nourishing glow. Simply put them into bags of an appropriate size for your eating habits, and stack them on the freezer shelves. There’s no need at all to lay them on trays so each is separate; when they thaw they will be soft and juicy and run together anyway, so save yourself some time at this busy period of the year – use it to crop your beans and thin your carrots (if you’re lucky enough to have had any germinate this terrible year!) and pick off slugs.

Once you have picked all the fruit, take the nets off promptly so the bushes don’t grow through the nets. Although some folk like to prune blackcurrants at this time of year, by cutting out a quarter or so of the older wood with fruit on it, which makes for easy picking, the main time to prune soft fruits is after their leaves have fallen in late autumn, early winter. Make sure you know the different pruning requirements of the different fruits; there’s an earlier Plotlines on this subject.

Enjoy the fruit feast and boost your health while they last…….
