How to Turn Your Patch of Earth From Barren to Bountiful
By Courtney Lindwall
Growing your own juicy tomatoes or crisp peppers sounds idyllic. But in practice, backyard farming can be daunting. Many gardeners dealing with pests, weeds and unpredictable weather quickly find themselves questioning whether they are working with nature or against it.
Just ask John and Molly Chester, who bought a sandy, barren plot of land in Southern California eight years ago in the hopes of starting the farm of their dreams. New to farming, the couple relied on holistic, regenerative practices (and a lot of trial and error) to revive Apricot Lane Farms. Through their hard work, the 214 acres are now a lush, largely regenerating ecosystem with fertile soil, diverse animal life and an abundant orchard with well over 75 varieties of fruit trees. Better yet: The farm never uses toxic, synthetically derived pesticides, which can kill soil microorganisms, harm pollinators and other wildlife, pollute waterways and make us sick.
John and Molly Chester
The Chesters' story, recounted in the documentary The Biggest Little Farm, is a testament to the wisdom of nature's own fine-tuned systems — and the remarkable rewards that gardeners will reap if they follow its lead. Here's how to cultivate a bit of Apricot Lane Farms' success in your own backyard.
Feed Your Soil
When the Chesters arrived at Apricot Lane Farms, the ground was dry, hard and mostly devoid of life. They knew they'd need to convert dead dirt back into soil before they could grow any crops. "When it's biologically diverse, soil is like this alchemizer of death into life, but you have to feed it," John said. Feeding the soil means building its biota — its below-the-surface ecosystem of microorganisms like bacteria and fungi, which break down decaying organic matter and infuse the soil with nutrients for the next cycle of plant life.
If you find yourself with similarly unhealthy soil, the Chesters recommend worm compost tea: worm waste steeped in water to make a liquid fertilizer teeming with beneficial microorganisms. At Apricot Lane Farms, the couple built an entire vermicomposting (worm composting) facility, but you can make do at home. Just put some worm castings, i.e. the black earthy-looking particles in your compost bin (you can also purchase a bag of castings) into a bag made from old panty hose, cheesecloth or a porous T-shirt. Add the tea bag to a pitcher or bucket of water. "Brew" your tea by adding a sugar supply like molasses for the bacteria (which will feed and multiply) and a small aerator (like a bubbler you'd add to a fish aquarium), which will concentrate the beneficial aerobic microorganisms. Let it bubble for one to two days, stirring occasionally, until a layer of foam develops — a good sign of active microorganisms. Apply to your soil within 48 hours. (If you'd like more information before brewing your own, step-by-step recipes and video tutorials on making worm tea abound.)
Plant Cover Crops
Cultivating native grasses, or simply refraining from ripping out last year's garden plants, will help you maximize the number of living roots in the ground, which offers many benefits to your soil. But by far the best means of nourishing and building up your soil is by planting cover crops. Farmers often plant them after the primary crop has been harvested or in areas that would otherwise be bare. And as John and Molly can attest, they're a critical component of any holistic farming practice. Not only do they protect exposed soil from the baking sun, which can kill critical fungal communities and other important microorganisms, but they also prevent erosion, naturally suppress weeds, improve soil quality, sequester carbon from the atmosphere and minimize flooding.
Cover crops can also enrich your backyard garden. Many gardeners plant them in the fall, in order to protect the soil through the winter and into the spring. Cover crops can also carry nitrogen from the air down into the soil, eventually making it available for the roots of other plants. Come spring, you can then turn these plants into "green manure" by mixing them into the soil and letting them decompose, which releases beneficial nutrients. "Cover crops are protecting this complex universe beneath the ground," John said. "They're also creating soil structure with their roots and increasing oxygen so that you get healthy, aerated soil that is filled with aerobic bacteria instead of anaerobic." At Apricot Lane Farms, cover crops include a "cocktail of grasses and legumes," though the best species for your backyard will depend on climate and your garden's specific needs, be it weed resistance or soil regeneration.
A few common cover crop varieties to investigate:
- Hairy vetch: This legume is hearty, resilient and a powerful nitrogen fixer. Its long roots also help break up soil.
- Buckwheat: Known as a "smotherer," this cover crop will naturally help keep weeds at bay while attracting pollinators. It can then easily be tilled into the soil.
- Clover: The many species of this legume are known to be versatile and powerful nitrogen fixers.
- Alfalfa: This crop's long roots help aerate and bring up nutrients deep within the soil.
- Peas: These legumes taste good, yes, but they also fix nitrogen and crowd out weeds, too.
- Marigold: Well known for its vibrant flowers, this plant also naturally controls pests like insects, frogs, fungi and weeds.
Maintain Habitats for Pollinators and Other Native Wildlife
Biodiversity rules at Apricot Lane Farms. By planting hundreds of plant species with a wide variety of roles, the Chesters have invited in diverse animal life. "Think about an ecosystem as the planet's immune system," John said. "You're trying to imitate that biodiversity." In other words, a diverse ecosystem has better odds of being able to heal itself. Keeping as many pieces as possible of that ecosystem intact provides a natural check on any one plant, animal or disease running amok.
Here are some biodiversity boosters for your own backyard:
- Introduce native flowering species that provide food for visiting pollinators.
- Hang a bee nesting box somewhere it can get sunlight and warmth.
- Provide green, leafy plants for caterpillars to eat, such as milkweed for the monarch butterfly.
- Set up a small wood pile, using brush or old logs, as shelter for lizards, fungi and snakes (the latter can eat other pests, like slugs or rodents).
- Plant trees or shrubs that provide plenty of nesting and cover for birds, or set up a bird house.
- Add a barn owl box or just a simple roosting perch to a pole. Owls and hawks help with rabbits and gophers.
- If you have the space, create a reliable water source in the form of a pond or container garden, which will make your yard more attractive to birds, frogs and dragonflies. Stem the problem of mosquitoes by including goldfish or guppies, which eat the bugs.
- Plant a diversity of cover crops. Instead of just using clover, for instance, mix your clover seeds with some hairy vetch, legumes and more to help your soil reap a diversity of benefits.
To Manage Pests, Play Detective, Then Look to Nature to Help Crack the Case
Over the years, the Chesters have dealt with everything from snail infestations in the orchard to hungry coyotes picking off their chickens. But the challenges have only made them better problem solvers, says John. He suggests that every gardener facing an intrusion — whether by pest, predator or disease — ask a few questions before attempting to control it, especially through artificial means like pesticides or other harsh chemicals.
For starters, understand the source of the problem and what might be fueling it, he says. Then look at what its food is, and in turn what eats it. Finally, ask what conditions it does not like and what conditions benefit its predators.
With those answers, you may find a nature-friendly solution. Take slugs, the bane of many a gardener. If they're chomping down on too many of your leafy plants, think first of what could provide a natural check. Toads and beetles will snack on the slugs if given the proper habitat themselves, potentially ridding you of your problem without requiring use of chemical pesticides. You can also address what snails don't like — sharp, rough ground — and put a layer of crushed eggshell around your plants, which act as a natural deterrent.
"You start to frame the complexity and context of the things you're trying to coexist with," John said. "It's not harmony you want," he added, but a "comfortable level of disharmony."
Looking to take the next step? Consider connecting with a master gardener program in your home state. These programs will not only help you hone your own green thumb but also set you up to train others in your community who want to make a difference in their backyard or garden plot.

A Cute But Threatened Species<p><a href="https://www.worldwildlife.org/stories/what-is-a-pangolin" target="_blank">Pangolins</a> are the only mammals wholly-covered in scales, which they use to protect themselves from predators. They can also curl up into a tight ball.</p><p>They eat mainly ants, termites and larvae which they pick up with their sticky tongue. They can grow up to 1m in length from nose to tail and are sometimes referred to as scaly anteaters.</p><p>But <a href="https://www.sciencedirect.com/science/article/pii/B9780128155073000332" title="Chapter 33 - Conservation strategies and priority actions for pangolins" target="_blank">all eight</a> pangolin species are classified as "<a href="https://www.pangolins.org/tag/endangered-species/" target="_blank">threatened</a>" under International Union for Conservation of Nature <a href="https://www.iucnredlist.org/search?query=pangolin&searchType=species" target="_blank">criteria</a>.</p><p>There is an unprecedented demand for their scales, primarily from countries in Asia and <a href="https://conbio.onlinelibrary.wiley.com/doi/10.1111/conl.12389" title="Assessing Africa‐Wide Pangolin Exploitation by Scaling Local Data" target="_blank">Africa</a> where they are used in food, cultural remedies and <a href="https://www.nature.com/articles/141072b0" title="Chinese Medicine and the Pangolin" target="_blank">medicine</a>.</p><p>Between 2017 and 2019, seizures of pangolin scales <a href="https://www.nationalgeographic.com/animals/2020/02/pangolin-scale-trade-shipments-growing/" target="_blank">tripled in volume</a>. In 2019 alone, 97 tons of pangolin scales, equivalent to about 150,000 animals, were <a href="https://oxpeckers.org/2020/03/nigeria-steps-up-for-pangolins/" target="_blank">reportedly</a> intercepted leaving Africa.</p>
Reintroduction of an Extinct Species<p>Each year in South Africa the African Pangolin Working Group (<a href="https://africanpangolin.org/" target="_blank">APWG</a>) retrieves between 20 and 40 pangolins through intelligence operations with security forces.</p><p>These pangolins are often-traumatised and injured and are admitted to the <a href="http://www.johannesburgwildlifevet.com/our-hospital" target="_blank">Johannesburg Wildlife Veterinary Hospital</a> for extensive medical treatment and rehabilitation before they can be considered for release.</p><p>In 2019, seven rescued Temminck's pangolins were reintroduced into South Africa's <a href="https://www.andbeyond.com/destinations/africa/south-africa/kwazulu-natal/phinda-private-game-reserve/" target="_blank">Phinda Private Game Reserve</a> in the KwaZulu Natal Province.</p><p>Nine months on, five have survived. This reintroduction is a world first for a region that last saw a viable population of this species in the 1980s.</p><p>During the release, every individual pangolin followed a strict regime. They needed to become familiar with their new surroundings and be able to forage efficiently.</p>
A ‘Soft Release’ in to the Wild<p>The process on Phinda game reserve involved a more gentle ease into re-wilding a population in a region that had not seen pangolins for many decades.</p><p>The soft release had two phases:</p><ol><li>a pre-release observational period</li><li>an intensive monitoring period post release employing GPS satellite as well as VHF tracking tags.</li></ol>
Why Pangolin Reintroduction is Important<p>We know so little about this group of mammals that are vastly understudied and hold many secrets yet to be discovered by science but are on the verge of collapse.</p><p>The South African and Phinda story is one of hope for the Temminck's pangolin where they once again roam the savanna hills and plains of Zululand.</p><p>The process of relocating these trade animals back into the wild has taken many turns, failures and tribulations but, the recipe of the "soft release" is working.</p>

In a move that environmentalists warned could further imperil hundreds of endangered species and a protected habitat for the sake of profit, President Donald Trump on Friday signed a proclamation rolling back an Obama-era order and opening nearly 5,000 square miles off the coast of New England to commercial fishing.
Why You Should Wash Fresh Produce<p>Global pandemic or not, properly washing fresh fruits and vegetables is a good habit to practice to minimize the ingestion of potentially harmful residues and germs.</p><p>Fresh produce is handled by numerous people before you purchase it from the grocery store or the farmers market. It's best to assume that not every hand that has touched fresh produce has been clean.</p><p>With all of the people constantly bustling through these environments, it's also safe to assume that much of the <a href="https://www.healthline.com/nutrition/fresh-vs-frozen-fruit-and-vegetables" target="_blank">fresh produce</a> you purchase has been coughed on, sneezed on, and breathed on as well.</p><p>Adequately washing fresh fruits and vegetables before you eat them can significantly reduce residues that may be left on them during their journey to your kitchen.</p><p><strong>Summary</strong></p><p><strong></strong>Washing fresh fruits and vegetables is a proven way to remove germs and unwanted residues from their surfaces before eating them.</p>
Best Produce Cleaning Methods<p>While rinsing fresh produce with water has long been the traditional method of preparing fruits and veggies before consumption, the current pandemic has many people wondering whether that's enough to really clean them.</p><p>Some people have advocated the use of soap, <a href="https://www.healthline.com/nutrition/white-vinegar" target="_blank">vinegar</a>, lemon juice, or even commercial cleaners like bleach as an added measure.</p><p>However, health and food safety experts, including the Food and Drug Administration (FDA) and Centers for Disease Control (CDC), strongly urge consumers not to take this advice and stick with plain water.</p><p>Using such substances may pose further health dangers, and they're unnecessary to remove the most harmful residues from produce. <a href="https://www.healthline.com/health/chlorine-poisoning" target="_blank">Ingesting commercial cleaning chemicals</a> like bleach can be lethal and should never be used to clean food.</p><p>Furthermore, substances like lemon juice, vinegar, and produce washes have not been shown to be any more effective at cleaning produce than plain water — and may even leave additional deposits on food.</p><p>While some research has suggested that using neutral electrolyzed water or a baking soda bath can be even more effective at removing certain substances, the consensus continues to be that cool tap water is sufficient in most cases.</p><p><strong>Summary</strong></p><p><strong></strong>The best way to wash fresh produce before eating it is with cool water. Using other substances is largely unnecessary. Plus they're often not as effective as water and gentle friction. Commercial cleaners should never be used on food.</p>
How to Wash Fruits and Vegetables With Water<p>Washing fresh fruits and vegetables in cool water before eating them is a good practice when it comes to health hygiene and food safety.</p><p>Note that fresh produce should not be washed until right before you're ready to eat it. Washing fruits and vegetables before storing them may create an environment in which bacterial growth is more likely.</p><p>Before you begin washing fresh produce, <a href="https://www.healthline.com/health/how-long-should-you-wash-your-hands" target="_blank">wash your hands well</a> with soap and water. Be sure that any utensils, sinks, and surfaces you're using to prepare your produce are also thoroughly cleaned first.</p><p>Begin by cutting away any bruised or visibly rotten areas of fresh produce. If you're handling a fruit or vegetable that'll be peeled, such as an orange, wash it before peeling it to prevent any surface bacteria from entering the flesh.</p><p>The general methods to wash produce are as follows:</p><ul><li><strong>Firm produce.</strong> Fruits with firmer skins like apples, lemons, and pears, as well as <a href="https://www.healthline.com/nutrition/root-vegetables" target="_blank">root vegetables</a> like potatoes, carrots, and turnips, can benefit from being brushed with a clean, soft bristle to better remove residues from their pores.</li><li><strong>Leafy greens.</strong> Spinach, lettuce, Swiss chard, leeks, and cruciferous vegetables like Brussels sprouts and bok choy should have their outermost layer removed, then be submerged in a bowl of cool water, swished, drained, and rinsed with fresh water.</li><li><strong>Delicate produce.</strong> Berries, mushrooms, and other types of produce that are more likely to fall apart can be cleaned with a steady stream of water and gentle friction using your fingers to remove grit.</li></ul><p>Once you have thoroughly rinsed your produce, dry it using a clean paper or cloth towel. More fragile produce can be laid out on the towel and gently patted or rolled around to dry them without damaging them.</p><p>Before consuming your fruits and veggies, follow the simple steps above to minimize the amount of germs and substances that may be on them.</p><p><strong>Summary</strong></p><p><strong></strong>Most fresh fruits and veggies can gently be scrubbed under cold running water (using a clean soft brush for those with firmer skins) and then dried. It can help to soak, drain, and rinse produce that has more dirt-trapping layers.</p>
The Bottom Line<p>Practicing good food hygiene is an important health habit. Washing fresh produce helps minimize surface germs and residues that could make you sick.</p><p>Recent fears during the <a href="https://www.healthline.com/coronavirus" target="_blank">COVID-19 pandemic</a> have caused many people to wonder whether more aggressive washing methods, such as using soap or commercial cleaners on fresh produce, are better.</p><p>Health professionals agree that this isn't recommended or necessary — and could even be dangerous. Most fruits and vegetables can be sufficiently cleaned with cool water and light friction right before eating them.</p><p>Produce that has more layers and surface area can be more thoroughly washed by swishing it in a bowl of cool water to remove dirt particles.</p><p>Fresh fruits and vegetables offer a number of healthy nutrients and should continue to be eaten, as long as safe cleaning methods are practiced.</p>

From the mythical minotaur to the mule, creatures created from merging two or more distinct organisms – hybrids – have played defining roles in human history and culture. However, not all hybrids are as fantastic as the minotaur or as dependable as the mule; in fact, some of them cause human diseases.
When Looking Through a Microscope Isn’t Close Enough.<p>For the last few years, <a href="http://www.rokaslab.org/" target="_blank">our team at Vanderbilt University</a>, <a href="https://www.researchgate.net/lab/Gustavo-Goldman-Lab" target="_blank">Gustavo Goldman's team at São Paulo University in Brazil</a> and many other collaborators around the world have been collecting samples of fungi from patients infected with different species of <em>Aspergillus</em> molds. One of the species we are particularly interested in is <a href="https://doi.org/10.1006/rwgn.2001.0082" target="_blank"><em>Aspergillus nidulans</em>, a relatively common and generally harmless fungus</a>. Clinical laboratories typically identify the species of <em>Aspergillus</em> causing the infection by examining cultures of the fungi under the microscope. The problem with this approach is that very closely related species of <em>Aspergillus</em> tend to look very similar in their broad morphology or physical appearance when viewing them through a microscope.</p><p>Interested in examining the varying abilities of different <em>A. nidulans</em> strains to cause disease, we decided to analyze their total genetic content, or genomes. What we saw came as a total surprise. We had not collected <em>A. nidulans</em> but <em>Aspergillus latus</em>, a close relative of <em>A. nidulans</em> and, as we were to soon find out, <a href="https://doi.org/10.1016/j.cub.2020.04.071" target="_blank">a hybrid species that evolved through the fusion of the genomes</a> of two other <em>Aspergillus</em> species: <em>Aspergillus spinulosporus</em> and an unknown close relative of <em>Aspergillus quadrilineatus</em>. Thus, we realized not only that these patients harbored infections from an entirely different species than we thought they were, but also that this species was the first ever <em>Aspergillus</em> hybrid known to cause human infections.</p>
Several Different Fungal Hybrids Cause Human Disease.<p>Hybrid fungi that can cause infections in humans are well known to occur in several different lineages of single-celled fungi known as yeasts. Notable examples include multiple different species of <a href="https://doi.org/10.1002/yea.3242" target="_blank">yeast hybrids</a> that cause the human diseases <a href="https://rarediseases.info.nih.gov/diseases/6218/cryptococcosis" target="_blank">cryptococcosis</a> and <a href="https://www.cdc.gov/fungal/diseases/candidiasis/index.html" target="_blank">candidiasis</a>. Although pathogenic yeast hybrids are well known, our discovery that the <em>A. latus</em> pathogen is a hybrid is a first for molds that cause disease in humans.</p>
(Left) Candida yeasts live on parts of the human body. Imbalance of microbes on the body can allow these yeasts, some of which are hybrids, to grow and cause infection. (Right) Cryptococcus yeasts, including ones that are hybrids, can cause life-threatening infections in primarily immunocompromised people. Centers for Disease Control and Prevention<p><a href="https://doi.org/10.1371/journal.ppat.1008315" target="_blank">Why certain <em>Aspergillus</em> species are so deadly</a> while others are harmless remains unknown. This may in part be because <a href="https://doi.org/10.1016/j.fbr.2007.02.007" target="_blank">combinations of traits, rather than individual traits</a>, underlie organisms' ability to cause disease. So why then are hybrids frequently associated with human disease? Hybrids inherit genetic material from both parents, which may result in new combinations of traits. This may make them more similar to one parent in some of their characteristics, reflect both parents in others or may differ from both in the rest. It is precisely this mix and match of traits that hybrids have inherited from their parental species that <a href="https://www.nytimes.com/2010/09/14/science/14creatures.html" target="_blank">facilitates their evolutionary success</a>, including their ability to cause disease.</p>
