Peak of the growing season!

Yesterday was a lovely day on the Farm.  Bumper harvest, everything looking great.  Some children to amuse us.

David Mitchell, the farmer, had left us about 150 spare straw bales, which we rolled into lines to act as windbreaks, like a walled garden. Heavy work though!

The Tao of grass cutting

I’ve been contemplating the most sustainable way to keep both my lawn and my longer grass under control. I’ve seen a new push mower advertised that claims that its ergonomic design makes it 60% easier to push than other mowers. But although it uses muscle power rather than petrol, it’s still a fairly complex piece of kit with parts that no doubt come from all over the globe and have a relatively high ecological footprint.

And there is an alternative. Hanging in the shed is an old fashioned English scythe. It’s rather a beautiful thing with a substantial steel blade attached to a long and gently curved wooden handle, referred to as the snath. I bought it several decades ago in Saffron Walden market, taking great care as I threaded my way back to the car park through the throng of busy shoppers! A kindly technician at Otley College set it up for me – the two handles can be positioned along the snath to suit the height of the user – but I never took time to learn to use it properly.

So last week I consulted local expert, Simon Lamb, who, like many modern-day scythe enthusiasts, uses an Austrian scythe. Sadly, the English scythe is less popular now because the Austrian blades are hand-forged and carefully shaped to increase their efficiency. They are also lighter, which means that the snath can be lighter. The Austrian factory that supplied the blade of my newly-purchased scythe has been operating for over 500 years.

Simon came and viewed my unkempt lawn and overgrown wildflower patch and showed me how a well-sharpened scythe wielded by an experienced hand can cut quickly and efficiently through grass and weeds. He made it look very easy, but then it was my turn. Surprisingly, I found it rather meditative. The gentle swinging action is not unlike a tai chi exercise and I felt disinclined to stop. The experience of guiding the blade through grass, adjusting to the vegetation as it changes across the site, builds a relationship with the garden that you don’t get from dominating it with a heavy petrol-driven piece of machinery. And there is great pleasure in developing the knowledge and skill needed to do a job well, especially when the alternative pollutes the atmosphere with noise and fumes.

Simon Fairlie, who imports and sells Austrian scythes, expresses it beautifully on his website when he says: “There is a magic in mowing which puts the rhythm of the body and the dynamics of a community in touch with the breathing of the earth”.

Summer twilight

At this time of year, with most of the summer before us, it seems paradoxical that the days are already shortening and the year progressing inexorably towards winter. But with last Saturday’s summer solstice, that is exactly what is happening. Once again the holly king and the oak king, rulers of the solar year, have fought their solstice battle, and the holly king now rules over these next six months of the declining sun.

Although considered to be the first day of summer, when the sun reaches its farthest point north of the equator, there is a seasonal temperature lag, which means that we have to wait for July and August for the hottest days. The cause of this lag is the role of the land and sea as natural storage heaters, absorbing the sun’s energy and gradually releasing it back into the atmosphere as heat. The oceans take longer to heat up compared to the land, and at this time of year are still relatively cool due to low spring temperatures.

But we can enjoy the long days and short nights while we wait for the dog days of summer. In fact, strictly speaking, there is no real night since twilight continues throughout the whole period from dawn until dusk. Twilight occurs when there is no direct sun but refracted sunlight still provides some light. Astronomically, morning twilight begins when the sun is 18° below the horizon, and ends in the evening when the sun drops back to 18° below the horizon. At the winter solstice, morning twilight lasts only from six until 8 am, and evening twilight from a quarter to four until 6 pm. But at the summer solstice evening twilight does not start until 9.20 pm and continues right through the night, ending at 4.30 in the morning.

Some animals are most active during twilight and these are referred to as crepuscular, the word derived from the Latin crepusculum, meaning twilight. Bats, for example, hunt during the twilight hours, thereby avoiding diurnal predators, although the species that emerge earliest from their daytime roosts are the fastest flyers and most able to avoid diurnal predators. The exceptional daytime vision of diurnal hunters such as kestrels diminishes rapidly as dusk light levels fall. By contrast, the large eyes of owls function well in poor light, and little owls in particular are crepuscular predators.

Ne’er cast a clout…

The mild weather last month saw me sally forth coatless on my early morning walks, ignoring the old adage to “ne’er cast a clout ‘til May be out”.

But does May refer here to the month or to the hawthorn blossom, which is also called May or Mayflower? There seems to be some dispute about this.

The Woodland Trust claims that the saying refers to the hawthorn, which flowers in May and early June, although first blossom is frequently recorded in April. There is an advantage to this assumption because the time of flowering of wild plants is affected by temperature and therefore provides a more reliable guide than a fixed date such as the first of June, when temperature may vary considerably. For example, since 1910, average May temperatures across England have ranged from 8.5°C in 1941 to 13°C in 1992 and 2008.

Indeed, it is thought that, due to climate change, spring in the UK is advancing, with plants such as the hawthorn flowering earlier. A 2002 study of 385 British plants found that the dates that they first flowered were, on average, 4½ days earlier than they had been in the previous 40 years.

On the other hand, the Oxford Dictionary of English Proverbs gives the first known record of this saying as the 1627 Spanish version, ‘Hasta Mayo no te quites el sayo’, meaning ‘Don’t leave off your coat until May’, referring to the month rather than the flower. But it is not unlikely that the saying originated in England before crossing the channel, so it is just possible that a translation error switched the meaning from the flower to the month.

Certainly hawthorn is a conveniently ubiquitous guide to your wardrobe choices. It is native to the UK and very common everywhere apart from northern Scotland. It is one of the most widespread hedgerow species, its dense thorn-bearing branches producing a very effective stock-proof hedge, but it will grow into a small tree with a height of around 30 feet when left uncut. It can be long-lived, and the Hethel Old Thorn in Hethel churchyard is reputed to be over 700 years old.

Skills, knowledge and consumerism

Three or four hours spent tying knots in the garden this weekend gave me time to reflect on the relationship between skills, knowledge and consumerism.

The knots in question are known as square lashing. You start with a clove hitch, then three lashing turns followed by three frapping turns, finishing up with a second clove hitch. The cause of all this activity was my decision to try out ‘square foot gardening’, an engineer-designed method of vegetable gardening that involves dividing raised beds into a grid of squares with sides one foot long, and planting different crops in each square. Having a surplus of bamboo canes, these seemed a good solution for constructing a grid to divide each of my five-foot square beds. I just needed something to hold the canes firmly in place where they crossed. My first thought was to look for something in the garden centre that would hold the canes securely, but then, in a book on knots, I discovered ‘square lashing’, a knot that is used to hold two poles at right angles to each other, and is ideal for trellises and similar structures.

Reflecting as I tied my knots (48 in total), I remembered when I first set up house and went to the supermarket for carpet cleaner, sink cleaner, furniture polish, floor cleaner, oven cleaner, window cleaner, and so on. The conveniently labelled bottles made it clear which product to use for which task, so no knowledge was required on my part. Since then I have learned more about the properties of basic materials and now do all my household tasks with lemon, vinegar, salt, bicarbonate of soda, linseed oil and beeswax.

Our grandparents had an inherited knowledge of simple household products, but with the advent of commercially-produced, tailored cleaning solutions, we were able to neglect this traditional expertise. But relying on these ‘scientifically proven’ formulations with their clearly printed instructions, we gradually lose the skills and wisdom accumulated over generations, creating an ever-increasing dependence on commercial products.

Yes, tying those 48 knots was time-consuming. But at the end of the task I not only had the grids I needed for my square foot garden; I had also gained a skill, together with the knowledge that a wide variety of knots are available to assist with many tasks in the garden and in the home. I wouldn’t have got that from the garden centre!

Early spring rhubarb

At a time of year when there’s not much fruit to harvest in the garden, rhubarb that has been forced for an early crop is a rare treat. Of course, rhubarb is not technically a fruit but a vegetable, and the part that is eaten is the long fleshy petiole or leafstalk. It is rich in vitamin C and fibre, and it contains reasonable amounts of vitamins A and K, potassium and calcium.

During January, rhubarb is forced by covering the crowns with a forcing pot, large bucket, or anything that will exclude the light. The dormant buds inside the pot are then insulated with straw or dry leaves. Champagne is an early variety that forces well, while Victoria is also good for forcing and is a heavy cropper.

In Yorkshire, rhubarb is forced commercially by growing in forcing sheds, where it is harvested in mid-winter by candlelight.

From late winter onwards, harvest rhubarb stems by pulling them outwards with a slight twist. Pick only the young pink stems, before they become green and thick, coarser and more acidic. Allow plenty of leaves to remain on the plant to continue to photosynthesise and encourage further growth. During a glut, freeze surplus rhubarb by cutting into chunks, open-freezing and then storing in bags. Rhubarb will continue to crop until midsummer, but forced crowns should be left for 2-3 years to recover before they are forced again.

At the end of the season, around mid-autumn, when the leaves start to die back, remove the old foliage and expose the crowns to frost. Divide the crowns every 4-5 years in mid-spring, just as the soil is warming up. Don’t pick any stems from these plants until the second year so that they have time to develop.

Forced rhubarb is mild, sweet and tender and needs less cooking than the main crop. Stew or roast with orange or ginger for an easy dessert.

Rhubarb leaves contain oxalic acid and, in consequence, are poisonous. Exploiting this characteristic, the leaves have traditionally been used to make an insecticide to control aphids on non-edible plants such as roses, and planting rhubarb near aquilegias is said to keep red spider mite away. Rhubarb also deters blackspot from roses, while small pieces of rhubarb included in the planting hole are said to protect brassicas from clubroot.

Northern lights

Last month Norfolk was treated to a rare sight, the Aurora Borealis. The spectacular show was due to a coronal mass ejection from the sun. This is a fast moving cloud of charged particles emitted when a sunspot erupts, producing a solar flare. The charged particles interact with atoms of the Earth’s atmospheric gases near the magnetic poles, and the burning gases create a display of ethereal coloured lights – oxygen produces green and yellow lights, nitrogen produces blue, and red and violet can also be seen. The aurora is usually only visible above the north and south magnetic poles, but under the right conditions can be seen at other latitudes. The display in Norfolk is said to have started around 8 pm in the evening and to have lasted for several hours.

The Aurora Borealis is also known as the Northern Lights, and the equivalent in the southern hemisphere, the Aurora Australis, is known as the Southern Lights. Other names for the Northern Lights include Merry Dancers and Lord Derwentwater’s Lights. This last name refers to James Radclyffe, the third Earl of Derwentwater, who was an English Jacobite beheaded for rebellion on 24 February 1716, when the lights were said to be unusually brilliant.

There are many myths associated with the Northern Lights. They take the name Aurora from the Roman goddess of the dawn who flies across the sky every morning to announce the arrival of her brother, Sol, the sun. Her sister is Luna, the moon, and the morning dew is referred to as Aurora’s tears. According to Brewer’s 1870 Dictionary of Phrase and Fable, the lights were ascribed by “northern savages” to the merriment of ghosts, while Finnish legend suggests that the lights are caused by magical fire-foxes whose tails brush the sky, creating sparks. The Saami people of Lapland believed that the lights were the energies of the souls of the departed, or the fire of torches lighting their way to heaven. In Norway they were thought to be the spirits of old maids dancing in the sky, the Vikings called them the bridge to Valhalla, and the Australian aborigines interpreted them as the gods dancing. The lights may also have been the origin of early dragon legends from China and Europe, where they were interpreted as the dragons’ firey breath.

Connections with the land

February 6 was Waitangi Day in New Zealand, commemorating the signing of the Treaty of Waitangi in 1840. The treaty sought to formalise the relationship between the colonising British and the native Maori people, making New Zealand part of the British Empire, establishing a British Governor there, and guaranteeing Maoris rights to their land. However, Maori beliefs about the ownership and use of land are very different from those that were prevalent in Britain in the nineteenth century. Their spirituality is strongly associated with the land, and they believe there is a deep kinship between humans and the natural world. They appoint individuals or groups as guardians to protect the land, while customary practices maintain a balance between the human communities and nature.

This relationship with the land and nature is found in many indigenous cultures. Humans, nature and spirits have a place in an ordered universe, and the environment is protected by religion and ritual as well as by traditional management practices. Together with an intimate knowledge of the environment, this enables indigenous cultures to co-exist with, rather than exploit, nature. The land also gives indigenous people a sense of belonging to a place, and connects them with their past, present and future – their past because it is the home of their ancestors, the present because it provides all of their material needs, and the future because it is a legacy that they hold in trust for their children and grandchildren.

The importance of the land is reflected in the statement by the World Council of Indigenous Peoples that “next to shooting indigenous peoples, the surest way to kill us is to separate us from our part of the Earth”.

Many of us in the Western world do not have such an intimate connection with the land. We may not live in the same place as our forebears, and our children may not remain where we are living now. We do not rely on the area where we live for our material needs since much of our food and other provisions are produced in, and imported from, faraway places. We do not feel a sense of kinship with the natural world but, instead, see it as a source of material assets with economic value.

However, the Western world is increasingly recognising the value of traditional land management practices, and is seeking to protect them through “community protocols” that formalise in written form the customary laws that have sustained biodiversity for generations.
