The Hiding Place

February 25, 2018 Isidore Gnome

For decades now, when gardeners needed a windbreak or a privacy screen they have resorted to planting hedgerow monocultures of a few relatively fast growing evergreen species, among them the Leyland cypress. For some who prefer a more formal, planned look, that plan has sufficed, but others might look at such a hedgerow as boring and as a lost opportunity to bring more wildlife into their gardens. Planting with wildlife in mind takes a generous spirit, particularly for the gardener who is also trying to raise fruits and vegetables for their own consumption. There are trade offs and compromises involved.

One of the problems with a hedgerow monoculture occurs when one or more of the plants dies, creating a gap that must then be filled with the same kind of plant, sometimes at considerable expense if the new plant is not to be too conspicuous by its smaller size. The gardener can feel trapped, and the trap can get more enveloping and add even more expense if the reason for a plant’s death is a disease or pest, engaging the gardener in an endless battle. Sometimes it can be a blessing when a disease or pest spreads quickly from one plant in the monoculture to the next, ending the battle with its consequent frustrations and expenses and presenting the gardener with a blank slate after a tree removal company has carted away the battlefield fallen.

Instead of persisting in folly and boring landscaping, a gardener might decide it is wiser and more interesting to plant rows or clumps of a diverse assortment of trees and shrubs, more closely imitating nature. The gardener might look for evergreen trees for year round screening for the gardener and cover for wildlife; deciduous trees which with their tall, rounded crowns fill visual gaps between the conical forms of the evergreens, and add nuts and acorns for wildlife food; shrubs and small trees both evergreen and deciduous which give fruits and berries in different seasons; and finally a water source, preferably running rather than stagnant. That’s a privacy screen for the gardener and a home for wildlife, and it isn’t only for large properties, since there are almost always dwarf or semi-dwarf forms of trees available.

Inviting wildlife into the garden this way means being willing to compromise on the amount of produce left for the gardener, and also means protecting vulnerable young plants from the very same wildlife. This is a microcosm and an imitation of nature, after all, and not truly nature. In nature the loss of a few sapling trees here and there to deer browsing is not necessarily a catastrophe since there may be as many more that will survive to maturity. But for the gardener who may have space to plant only a few trees, the loss of even one young tree is important. An example would be the gardener who joins in the effort to restore the American chestnut to the landscape and helps the cause by buying and planting a few saplings at home. Unless that gardener cages the chestnut saplings for the first two or three years of their growth, deer will come along and browse the foliage and rub velvet off their antlers using the trunks of the saplings, debarking them. Caging is the only truly effective way to get deer to leave the chestnut saplings alone until they are big and strong enough to withstand their attentions.

On a small lot in particular a gardener should not expect to get very many fruits and berries for their own consumption. Birds love eating the same things, and they are outside all day every day, watching for ripeness, and when it comes the birds get to the fruits and berries very soon. Netting is a nasty business that tangles up birds and other critters, killing them, and it has no place in a garden planted for wildlife. Either be content with gleaning a few fruits and berries here and there, or build a small greenhouse to grow a few protected plants. Gardeners with large plots of land have more options, both for the wildlife and for themselves. Plant native plants when possible, because they are better adapted to coexist with native wildlife. Once there are birds and frogs and other insect eaters living nearby, the gardener may actually find fewer pest and disease problems in the rest of the garden, and that alone makes it worth the trouble of devising a landscape scheme more varied and interesting than a soldier row of Leyland cypresses.

The Top Banana

November 5, 2017 Isidore Gnome

Since the loss of most of the Gros Michel, or Big Mike, banana plantations due to a destructive root rot by the middle of the twentieth century, the Cavendish has taken over as the most productive banana variety worldwide. By all accounts the Gros Michel was a more flavorful variety than the Cavendish, but growers who wanted to continue producing on a vast scale for the international market had no choice but to switch after fungus reduced the productivity of Gros Michel to an uneconomical level. Now the Cavendish faces similar destruction from another strain of the same fungus, and agronomists are scrambling to find a replacement for the Cavendish.

The Cavendish banana, like the Gros Michel, is a clone. One plant of Cavendish is exactly like the next plant of Cavendish. Such a monoculture is extremely susceptible to pest and disease problems because it cannot adapt through genetic accidents brought about by sexual reproduction. It’s a stationary target. Growers could turn to the extraordinary variety of other, sexually reproduced bananas, and they do just that locally in the tropical areas of the world where bananas grow. The problem for growers who sell internationally has always been finding disease and pest resistant varieties that would hold up under less than ideal shipping conditions and still be economically viable on a large scale.

The first in a series of animated commercials produced by the United Fruit Company in the 1940s for display in movie theaters. The singer was Monica Lewis.
Bananas naturally contain numerous large, hard seeds, making eating them a challenge. It is easier to comprehend the relationship of bananas to berries when confronted with all those seeds. Besides being unavoidable to banana eaters, the seeds were also viable. Modern commercial varieties like the Cavendish have been bred to have seeds that are barely noticeable, turning those varieties into convenience foods. Peel, eat, and don’t worry about the seeds. In the process of hybridizing banana varieties for less inconvenient seeds, agronomists also rendered the seeds unviable. The Cavendish, like the Gros Michel before it, reproduces only exact replicas of itself from parts of an existing plant, without benefit of differing input from any close relatives.

Reliably predictable results are great news for economic giants in any sphere, and agriculture is no exception. The American agribusinesses United Fruit and Standard Fruit, which eventually morphed into Chiquita and Dole, respectively, built themselves into indomitable international forces largely on the predictability of first the Gros Michel and then the Cavendish. They became enormously powerful, vertically integrated corporations that controlled the internal politics of many Latin American countries – the so-called banana republics – and pulled the strings of the United States’ foreign policy. All so that people in wealthy, temperate zone countries could enjoy a fruit that grew only in the tropics.

Unlike the spice trade, which also dealt in commodities that mostly grew in the tropics, bananas were and are a superfluous item in the diets of people outside the tropics. Spices were valued in the days before refrigeration on account of their utility in preserving other foods or making them more palatable. Bananas are high in potassium, an essential mineral, but so are potatoes and beans, both of which grow well in temperate zones, as well as being available for winter eating due to their good storage qualities. Bananas sold in temperate zone countries are luxury items available at affordable prices due to the ability of powerful international corporations to exploit cheap labor in tropical countries for growing a dependable crop capable of surviving shipment halfway around the world and arriving in salable condition.

The economic model developed by United Fruit and Standard Fruit in the early twentieth century has been copied and adapted ever since by growers and shippers of other produce, from grapes to mangoes, available now in temperate zone countries even in the middle of winter. As nice as it would be for large international banana producers to abandon monoculture with its reliance on pesticides and fungicides, only to have to abandon that one variety when its production is no longer economically sustainable, they may have no other choice if they want to continue with business as usual. It’s in the nature of their economic model. Locally sustainable small scale agricultural production would of course apply to bananas consumed in the tropics, as it always has, but not in colder countries, where they do not grow.

For all the convenience in the past century and more of being able to pick up a bunch of bananas at the grocer’s in countries where the average person would be more likely to see sub-tropical citrus fruit orchards than tropical banana plantations, not everyone enjoys bananas, or at least not the texture of actual bananas. They may like banana flavor, but they don’t care for the texture, which can be mushy and sticky, activating their gag reflex. For those people, the absence of bananas from the grocer’s would not be a painful loss. Certainly they would still like to have overripe bananas to use in banana bread and other delicious recipes. But unlike the supposedly fresh bananas for eating out of hand, bananas for cooking don’t have to look perfect. In that case, imperfect is just fine.

Too Much of a Good Thing

August 22, 2017 Isidore Gnome

Sugar can be derived from numerous plants, including beets, corn, and the fruit of trees, but it has come into its own since the Middle Ages in Europe as the refined product of the sugarcane plant, a perennial grass. The plant originated in New Guinea, and from there traders introduced to Asia, where it eventually found its way to southern Europe by way of Arab merchants. As noted from its origin, the plant grows in tropical or sub tropical climates. Europeans quickly developed a taste for refined sugar, but since the plant would not grow well in Europe or northern Africa, they needed to find either another source or another place to grow, or forever be at the mercy of Arab merchants, who kept the price high.

When European explorers stumbled upon the New World in their search for a trade route to the Far East that bypassed Arab middlemen, they were interested in exploiting sugar resources as much as spices. The tropical and sub tropical bands of the New World – the Caribbean, much of eastern South America, Central America, and the far southeastern portion of North America – turned out to be well suited for raising sugarcane. The problem was finding a suitably cheap labor source for the backbreaking and dangerous labor involved in sugarcane cultivation as well as refinement. The Europeans, after exhausting the Native Americans as a labor source, turned to Africa as a source of slave labor.

There were other plantation crops that Europeans raised in the New World exploiting slave labor, such as tobacco (a plant native to the western hemisphere) and cotton, but sugar was the big money maker for them, the linchpin of Atlantic trade from the 1500s well into the 1800s. Sugar grown on plantations in the New World traveled, some in the form of rum, to northeastern ports of North America and then on to Europe, where it was traded for manufactured goods; some of the manufactured goods then were traded in Africa for slaves, who were loaded onto ships destined for plantations in the New World, their voyage across the Atlantic being known as the Middle Passage of this triangle of trade. Some didn’t survive the voyage, and of the ones who did, many suffered abominably under harsh conditions in the sugar growing regions and elsewhere.

Hundreds of years later, sugar is still exacting a toll from poor black people, as well as poor and working class people generally. The European quest for cheap sugar succeeded all too well. Now it’s found in far too many supermarket foods and beverages, where in the case of processed foods it masks the loss of wholesome flavors. Sugary beverages like soda and many fruit drinks are especially egregious sources of the endocrine disrupting carbohydrates present in refined sugar that can lead to obesity and type 2 diabetes. These processed foods are easy to prepare and are relatively cheap and, because of the sugar in them, to some people they taste good enough.

“Big Rock Candy Mountain”, first recorded by Harry McClintock in 1928, is about a hobo’s idea of paradise. McClintock claimed to have written the song in 1895, based on tales from his youth hoboing through the United States. McClintock’s 1928 recording was used by Ethan and Joel Coen at the beginning of their 2000 film, O Brother, Where Art Thou?.

People could cut back their consumption of processed foods, and certainly they could drop sugary sodas and fruit drinks out of their diet and not lose any essential nutrients. People can use will power and self control, even though there is evidence that sugar’s effects on their health are more insidious than industry mouthpieces would have everyone believe. People can do all those things. But they don’t. Why not?

What if crack cocaine were as cheap as sugar? How about cigarettes? Opioids? What levels of consumption would we encounter then among the general population, and among the poor and working classes specifically? All those substances stimulate pleasure centers in the human brain, just like a good hit of sugar does in a smaller way, and all are ultimately destructive in high enough doses. Is sugar as destructive as those other addictive substances? No, not in the short term, and it would be ridiculous to equate a cookie with a hit of cocaine. In the long run, however, over the course of ten, twenty, or thirty years, sugar consumption at modern American levels of a hundred pounds or more per person per year is proving destructive enough. Time to turn some of that exhausted soil in the tropics over from growing monocultures of sugarcane for export to growing fruits and vegetables the locals could consume for themselves. We could easily cut back from two or three lumps of sugar to just one.

Where Have All the Bees Gone?

October 9, 2016 Isidore Gnome

Imagine going to the grocery store as usual and discovering after ingesting some of the food you brought home that it made you ill, weakened the immune system of some of your family, and killed others. You had no way of knowing what was about to happen, and if you want to eat you have no choice but to return to the same grocery store next week, taking your chances. There is no alternative. This is the situation for bees and other pollinators, whose grocery store consists of the flowers they have visited for thousands or millions of years. Massive die-offs of bees and butterflies have been in the news for many years now, and recently the U.S. Fish and Wildlife Service placed the yellow-faced bees of Hawaii on the Endangered Species List, the first bees to be included.

Use of broad spectrum pesticides in agriculture is partly responsible for the decline in bee populations, but an often overlooked contributing factor is the part homeowners play when they distribute similar pesticides on their lawns and gardens. Unlike the use of pesticides in agriculture which is done in the name of food production, homeowner use of pesticides is solely in the interest of aesthetics. Individuals can change this behavior more readily than they can the practices of large agricultural concerns.

Change starts in our own yards, and it starts with a change in perspective about what is acceptable and beautiful. Instead of insisting on a monoculture of grass in the lawn, change the definition of the lawn to include some flowering plants. Look on dandelions and clover as beneficial for the bees, rather than as weedy pests to be exterminated at whatever cost in time, money, energy, and collateral damage. An important aspect of Integrated Pest Management is tolerance of a certain amount of pest damage, however “pest” is defined, and the realization that perfection is neither attainable nor even desirable. Nature is messy. The bees prefer it that way, and will thank you for your part in letting it be. The hard part will be in convincing your neighbors of it while fluff from your dandelions drifts into their yards.
