5 Ways Home Gardeners Can Make More Robust Soil

As a child, Kristin Ohlson had easy access to gardens. Her grandparents maintained a small orchard and grew produce on their farm; her parents also planted huge plots of vegetables and flowers each year. While Ohlson didn’t develop a deeper agricultural interest until she grew up (all those hours harvesting vegetables cut into childhood playtime, after all), she eventually started researching how food is grown. And that research turned into a minor obsession.

In her 2014 book, The Soil Will Save Us, Ohlson documents how soil scientists are experimenting with cover crops, composting, no-till techniques, and other methods that help farmers reduce their reliance on fertilizer and rethink their relationships with soil. “Dirt First,” her more recent feature for Orion Magazine, and a Q&A with the Food & Environment Reporting Network (FERN) dive even deeper into the subject, exploring the role that microorganisms play in soil health, for both farm fields and backyard gardens.

“Plants pull carbon dioxide from the atmosphere through photosynthesis and create a carbon syrup,” she writes. “About 60 percent of this fuels the plant’s growth, with the remaining exuded through the roots to soil microorganisms, which trade mineral nutrients they’ve liberated from rocks, sand, silt, and clay—in other words, fertilizer—for their share of the carbon bounty.”

But before you chalk this all up as far too heady for the home gardener, check out her five easy steps for nurturing vegetables and flowers with natural methods based on that big-picture research—but applied to our own backyards.

1. DISTURB THE SOIL AS LITTLE AS POSSIBLE

Soil health starts with one basic principle: Don’t disturb the dirt. Sure, soil supports roots and helps hold up plants, but it also serves as a habitat for beneficial microorganisms.

“Underneath our feet is this incredible world teeming with billions of microorganisms that have been working in the soil for millions of years,” Ohlson says. “That ecosystem in the soil is what plants depend on for their nutrition, their water, and their defenses against chemicals, diseases, and insects.”

Rather than tilling garden rows and digging deep holes for new plants, she suggests leaving the soil structure as intact as possible. Poke small holes for seeds and dig slightly bigger spaces before planting seedlings.

2. MAKE PEACE WITH WEEDS

It may sound counter-intuitive—maybe even chaotic, in terms of landscaping—but weeds don’t need to be treated as an enemy. Even uninvited plants can help protect soil and feed the microorganisms at work below the surface.

“I used to dig up weeds or pull them out by the roots, but now I don’t want to disturb the soil. I go around with scissors and snip weeds off at the soil level instead,” says Ohlson. She then scatters clipped stems and leaves between the plants she wants to keep. This organic matter functions as mulch and acts as compost as it decomposes.

3. ENCOURAGE DIVERSITY

“In nature, there is this vast abundance of diversity—plants and insects and all kinds of life—in every square foot. This biodiversity helps feed and support the biodiversity in the soil,” she says. (Check out the incredible variety of plants in this enchanting Texas garden.)

Follow nature’s lead in your garden by growing a variety of vegetables, fruits, flowers, herbs, and other plants in close proximity. The variety promotes healthy, robust soil and might also attract a new mix of pollinators.

4. PLANT COVER CROPS


Every gardener has heard this one before, and Ohlson is a firm believer as well. She aims to keep her garden soil engaged, either by covering it in dead plant material or by nurturing live roots in the ground. Cover crops play a dual role. They interact with microorganisms by extending their roots as they grow, and they provide extra organic material to protect the soil once they’re harvested. In small gardens, simply clip cover crops with scissors and scatter over bare ground.

Not sure what kind of cover crop to plant? First, consider what might thrive in your location and climate. “Then, see what plants and flowers are native to your region,” Ohlson suggests. “But really, I think people can use almost anything, as long as it grows.” (These 5 cover crops will keep a small plot healthy.)

5. TRADE FERTILIZER FOR COMPOST

When plants rely on fertilizer, they get lazy. Their partnership with microorganisms in the soil changes, and that can impact the wider microbe community. By using compost instead, you’re enhancing the soil with a concentration of microorganisms and carbon that help plants thrive.

If making your own seems too messy or daunting, look into local sources. Some cities collect food waste and make the resulting compost available to the public. Elsewhere, garden and hardware stores sell organic compost by the bag. You might find regional farmers who can supply the materials you need, as well.

“I also put sticks, some food waste, and dead plant matter around my living plants. That keeps the benefits of compost happening on the most basic level,” Ohlson says.

FOR SMALL-SPACE GARDENERS

Ohlson’s overall advice is similar for gardeners who grow plants in pots or containers, where soil mindfulness is especially important.

“When water hits bare soil, it compacts that soil. Even the force of one raindrop can make an impact. So, the less that bare soil is exposed to water, the healthier that soil is,” she says. “Even in a small pot, I don’t want to be pouring water directly on the soil. I’d rather have it seeping through clipped plant material and reaching the soil in a gentler way.”

Ohlson has two raised beds in her own backyard and she packs them with a diverse selection of vegetables, flowers, and shrubs. “I plant things really close together and try to have a lot of live roots in the ground. It’s so rewarding to see the incredible production I get out of these two tiny raised beds,” she says.

How to Start an Organic Garden in 9 Easy Steps


The Benefits of Organic Gardening

You've been trying to eat more organic foods, both to decrease the amount of pesticides you and your family consume, and to help protect the environment from overloading with toxic chemicals. But organics can get a bit expensive, we know. Luckily, there's a way to grow your own delicious, fresh produce, while having fun and learning at the same time: organic gardening!

Don't know where to start? It is possible to hire someone to install and maintain a beautiful organic garden for you. But most of us can roll up our sleeves with a surprisingly small amount of effort. Remember, you can start small, even with just a single plant or two. Don't worry if things aren't perfect right away.

Organic gardening means you won't be using synthetic fertilizers or pesticides, but that doesn't mean your plants are left to fend for themselves. There are an array of tools you can use to bolster plant health and ward off pests. Organic gardening also isn't just about what you don't do, it's about trying to foster a more holistic, natural ecosystem. Read on for specific tips, taken from The Daily Green's expert garden blogger, Leslie Land, her New York Times book 1000 Gardening Questions & Answers and other sources.



Preparing the Soil

In order to get the best results with your new organic garden, you'll want to make sure the soil is properly conditioned. You have to eat, and so do plants, so make sure your veggies get lots of fresh nutrients. Good healthy soil helps build up strong, productive plants. Chemical soil treatments can not only seep into your food, but they can also harm the beneficial bacteria, worms and other microbes in the soil.

The best way to gauge the quality of your soil is to get it tested. You can get a home testing kit, or better, send a sample to your local agricultural extension office. For a modest fee you'll get a complete breakdown of pH and nutrient levels, as well as treatment recommendations (be sure to tell them you're going organic). That way you can tailor your gardening program. Typically, it's best to test in the fall, and apply any organic nutrients before winter.

Even if you don't have time for testing, you'll want to make sure your soil has plenty of humus -- the organic matter, not the similarly named Mediterranean spread. According to 1000 Gardening Questions & Answers, you'll want to mix in compost, leaf and grass clippings and manure. Manure should be composted, unless you aren't going to harvest or plant anything for two months after application. Preferably, get your manure from local livestock that have been organically and humanely raised -- and never use manure from animals that eat meat.





How to Make Good Compost

All gardens benefit from compost -- and preferably you can make your own on site. Hey, it's free! Compost feeds plants, helps conserve water, cuts down on weeds, and keeps food and yard waste out of landfills (where it produces methane), instead turning garbage into "black gold." Spread compost around plants, mix with potting soil, use to bolster struggling plants…it's hard to use too much!

The best compost forms from the right ratio of nitrogen- and carbon-rich organic waste, mixed with soil, water and air. It might sound like complicated chemistry, but don't worry too much if you don't have time to make perfect compost. Even a minimally tended pile will still yield decent results.
  1. To get started, measure out a space at least three feet square. Your compost heap can be a simple pile or contained within a custom pen or bin (some can be rotated, to improve results).
  2. Add alternating layers of carbon (or brown) material -- leaves and garden trimmings -- and nitrogen (or green) material -- such as kitchen scraps and manure, with a thin layer of soil in between.
  3. Top off the pile with four to six inches of soil. Turn the pile as new layers are added and water to keep (barely) moist, in order to foster microbe action. You should get good compost in as little as two months (longer if it's cold).
  4. A properly maintained compost pile shouldn't smell. But if it does add more dry carbon material (leaves, straw, or sawdust) and turn it more frequently.
  5. Even if you live in a city, you can do some composting under your counter with a tidy worm kit, or partner with a community garden.


Choose the Right Plants

It really pays to select plants that will thrive in your specific micro-conditions. As a general guide don't forget to check the USDA's Hardiness Zones (which have recently been updated by the National Arbor Day Foundation due to climate change). Choose plants that will be well adjusted to each spot, in terms of light, moisture, drainage and soil quality. Most gardens have gradations in these variables. The happier your plants are, the more resistant they'll be to attackers.

If you're buying seedlings, look for plants raised without chemical fertilizers and pesticides. A great place to look is at your local farmers' market, which may also have native plants and varieties well suited to your area. It's better to buy stocky seedlings with few, if any blooms yet, and with roots that don't look overcrowded.

Many things are best grown from seed, including sunflowers, annual poppies, evening-scented stock (Matthiola bicornis), coriander, dill, annual phlox (Phlox drummondii), larkspur, annual lupine, morning glories, sweet peas, squash and cucumbers.





Plant Crops in Wide Beds

Plants that you will be harvesting, such as vegetables or cutting flowers, should be grouped tightly in beds that you don't walk on (raised beds work great). Grouping reduces weeding and water waste, and helps you target compost and nutrients. Easier path maintenance helps lead to healthy soil. Ample space between rows helps promote air circulation, which repels fungal attacks.

Remember that seedlings won't always stay diminutive, and you do want to try to limit over shadowing. It's a good idea to thin crops based on nursery suggestions.

According to Leslie Land, if you have limited space and time, and want the highest returns of fresh organic produce, these plants are typically winners:

1. Indeterminate Tomatoes. So named because the vines keep getting bigger and producing new fruit until they are felled by frost.

2. Non-Hybrid (Old-Fashioned) Pole Beans. They keep growing and producing 'til frost -- assuming you keep them picked.

3. Zucchini. Everything they say about avalanches of zucchini is true, especially of hybrid varieties.

4. Swiss Chard. You can keep breaking off outer leaves for months, and every picking will be tender as long as plants get enough water.

5. Tall Snow Peas and Sugarsnaps. They grow readily and produce delicious rewards.


Proper Watering

The best time to water plants is usually in the morning. Why? Mornings tend to be cool and without strong winds, so the amount of water lost to evaporation is reduced. If you water in the evening plants stay damp over night, making them more likely to be damaged by fungal and bacterial diseases.

Ideally, you want to water the roots, not the greenery, which is easily damaged. A drip or soak system can work great, or just carefully water the bases of plants by hand.

Most experts recommend substantial, infrequent watering for established plants, typically a total of about one inch of water per week (including rain). One or two applications a week encourages deeper rooting, which promotes stronger plants. To avoid shocking tender greenery, try to use water at or near air temperature (collected rainwater is best).

With population growth and climate change putting increasing pressure on our precious freshwater supplies, it is becoming more important than ever to save water.


Weeding

Ah weeding. Even if you live in the Biosphere, you'll still get weeds, since their tiny seeds are pervasive. Pulling weeds by hand may sound like hard work -- and it can be -- but it also can be good exercise, and gets you outside in the fresh air. You don't want to pour toxic chemicals on your food, or where your children and pets play, right?

Reduce the number of weeds you have to contend with by applying mulch (which also helps protect the soil). According to Leslie Land, organic mulch that will rot down into the soil is almost always preferable to landscape fabric, although burlap and other materials can work in a pinch. Straw is cheap but doesn't last long. Wood chips are nice, but can get pricey. Many people opt to use lawn clippings, although it should be noted that because they are high in nitrogen, clippings should only be used on plants that need a lot of the nutrient, such as squash and lettuce.

If you get tired of weeding or aren't able to bend over, consider hiring some neighborhood kids. It's a good way to get to know others in your community. Remember too that raised beds can be made wheelchair accessible, and others can take advantage of wheeled stools, arthritis-friendly gardening tools and other equipment.


Protect Plants Without Toxic Pesticides

If your plants are being assaulted by pests, it may be a sign of other problems, so the first thing you should do is make sure they are getting enough light, nutrients and moisture. Also remember that a diverse garden helps prevent pests, by limiting the amount of one type of plant offered up to enemies, and boosting biodiversity.

It's a good thing to foster natural predators in your garden, such as frogs, toads, lizards, birds, and even bats. Beneficial insects can be your best friends, especially lady bugs (many nurseries even sell cans of them, though it's true there's a high probability they won't stick around). Leave a small source of water out to attract friendly predators. It's also a good idea to grow plants with small blossoms, such as sweet alyssum and dill, which attract predatory insects. Nets and row covers can also work.

It may sound surprising, but homeowners use more pesticides on their lawns and gardens than farmers do, acre for acre, according to EPA data. But there are organic alternatives that are much safer for you and our environment. Find out what problem you have (an agricultural extension service can help), then look for alternatives.

Organic weapons include Bacillus thuringiensis, a naturally occurring bacteria that disrupts the digestion of caterpillars and other leaf-eaters. You can also use horticultural oils, insecticidal soaps and garlic and/or hot pepper sprays.



Harvesting

Don't forget to harvest the fruits of your labor! Fresh organic produce also makes great gifts, educating your friends, neighbors and coworkers. Generally, the more you harvest, the more your plants will produce for you.

During peak harvest season, you'll likely find that it's best to check your garden every day. Got herbs? If you use them fresh pick them right before you need them. But if you'll be drying and storing them, it's best to wait until just before they flower, since they'll have the most flavor. Gather all herbs except basil in mid morning, shortly after dew has dried. Harvest basil in the late afternoon, since it will last longer after some time in the sun. It's best not to wash herbs before you dry or use them, since that can leach flaor (extra incentive for growing organic!).

When harvesting leafy greens pick sporadically from the entire crop, a little from each plant. For broccoli, wait until the central head is as large as it will get, before sending off buds for flowering. Cut it off right above the leaf node, and you'll likely get better production from the rest of the plant. In general, it's best to cut produce off with a sharp knife or scissors, versus ripping with your fingers, which can cause more damage to plant tissue.

If you get too much bounty, remember you can also freeze, store some types of produce in a root cellar, or take up canning. Enjoy!


Cleanup

If you have sick plants to remove, either during the season or at the end of the year, make sure you pull up the entire organism. Don't forget to rake up underneath, since diseased leaves can harbor problems for a long time. Put all infected material deep in the woods, in the ground at least a foot deep, or on the bonfire.

Most healthy or expired plants can actually be left in place over winter. You'll provide some food and habitat for birds and other wildlife, and plant cover can help protect your soil from eroding. It's better to chop off annuals then yank them out, because that way you'll leave soil intact, and help prevent weeds from gaining a foothold.

Organic Gardening: 10 Tips to Success

Organic gardening is the method of gardening that utilizes only materials derived from living things, ie. all natural plant foods and pesticides. Once you know the basic tenets of this practice, organic vegetable gardening is simple. And the payoff is enormous: no toxic chemicals, no waste, better for the environment as a whole, and not to mention a crop full of natural, delicious vegetables. Remember these 10 steps and you'll have a successful crop in no time!


Soil. It all begins here. Amending your soil with organic material such as composted manure or yard and kitchen scrap compost will get your dirt off to a good start. The inclusion of organic material provides a solid basis of nutrients for your plants which helps to cut down on the need for commercially made fertilizers and improves soil structure making it easier for your plant to absorb the important minerals they need. Sandy soil will not hold its moisture well. Heavy clay soil may prove too dense for healthy root development.

Fertilizer. In addition to compost, your plants will enjoy a healthy dose of other organic foodstuffs like worm poop and pee (we call this worm tea), eggshells, Epsom salts, bone meal, blood meal...the list goes on, but the key word is all-natural. Mother Nature knows what she's doing and these sources provide essential vitamins and minerals for your plants.

Beneficial insects. When planning your garden, educate yourself on which plants repel insects, which plants invite them, and what each bug eats. For instance, ladybugs eat aphids, which is a good thing because aphids will suck the life from just about any plant! By inviting ladybugs into your garden you are employing a natural form of pest control and not toxic chemicals.

Layout. When designing your garden, it's important to adhere to spacing guidelines for your plants. By keeping them close, their leaves will shade the ground beneath them. This not only cuts down on weed growth, but also helps the soil retain water, cutting down on water usage. Organic gardeners are excellent custodians of the environment. Too close, and you'll invite the growth of fungus and disease.

Companion planting.
Including a wide variety of plants in your garden and planting them according to their relationship with others helps in many ways. For instance, bean plants fix nitrogen into the soil, which corn plants use to produce healthy cobs. Corn provides support for the climbing vines of the bean family. Add squash to the base and you have instant weed control!

Crop rotation. This is the practice of rotating a plant's location from season to season. Relocating your plants cuts down on soil depletion and disease infestation. In addition, plants like beans will actually put nutrients into the soil that can be used by the next crop, ie. corn. Disease will be reduced because the organisms that infect one plant pose no harm to the next, so rotating eliminates the likelihood a disease will spread.

Water.
Conserving water is a key component of organic gardening. Good watering practices include the capturing and storing of rain, the use of drips hoses, and plenty of mulch. With a sprinkler system, a large amount of water can be lost to evaporation. If sprinklers must be used, it's best to water in the early morning or early evening hours. Using mulch around your plants is another way to conserve water because it keeps the soil moist longer, requiring less water to be used.

Weeds. Weed removal is best done by hand, without the use of chemicals. While tedious, this duty can be cut down tremendously by the use of smart planting. Remember, keeping plants close helps prevent weed growth. Natural mulch is another great method. Not only does it help prevent weeds, it has the added benefit of providing nutrients into the soil as it breaks down.

Cover crops. These are the plants you grow in between seasons. They help to replenish the soil with vital nutrients and prevent soil erosion. They can also be used to feed the beneficial insects in the absence of your vegetable crop and keep weeds at bay.

Seeds. Organic gardening is all about using sustainable methods and what better way to be self-sustaining than to use your own seeds! The practice of saving seeds has been around for centuries and ensures you "know what you grow." But to ensure purity and avoid cross-pollination, you must keep some distance between the same plants of different varieties. You don't want to be disappointed when you plant those tomato seeds next year and discover the result is a hybrid--and not the decadent beefsteak tomato you were looking forward to. Only heirlooms can produce the original fruit, not hybrids.

Organic vegetable gardening is all about sustainable practices. It's conservation at its best, because you are using what you have and what you can find in nature. From fall leaves to leftover food, you waste nothing in an organic garden. Plants help each other, insects play a role...why even Mother Nature helps by delivering an extra shot of nitrogen in every rain drop!

But more than being a good steward of the environment, organic gardening makes for a healthier you.

Composting 101


Understanding composting can be a bit intimidating. but fear not!...One of our favorite resources, Earth911 has compiled tons of great information to make the process of conjuring up your first compost pile a not-so-complicated challenge, hopefully increasing your knowledge and not stress! 
According to the EPA, 24 percent of the U.S. municipal solid waste stream is composed of food remnants and yard trimmings. If these materials were diverted to another use that kept them out of the trash, a significant portion of the country's everyday waste could be recovered for reuse.
Enter: composting. Grass clippings, food scraps and yard waste are all ideal materials to add to a compost pile. This means that starting one is about more than just creating a great soil booster for your garden or farm - it can cut down on your waste output as well.
For those who have been thinking about starting a pile for some time now, but are still unsure about taking on the challenge, understanding the basics of composting can make it a less intimidating process.

First Thing's First: What is Composting?

For households, composting is a way to recycle certain materials and kitchen scraps and turn them into a beneficial soil amendment for home gardens and reduce waste output.
For small-scale farms, composting is a way to utilize the residual plant and animal material generated and put it to good use as a fertilizer and soil-builder for future crop production.
In both cases, composting is the natural process of decomposition, sped up by a deliberate strategy in a concentrated environment to transform materials such as grass clippings, vegetable scraps, newspaper and more into a new material (known as "humus") that can then be incorporated back into the soil. Also, composting with worms, or vermicomposting, is another option over traditional composting using outdoor bins.

Break It Down: The Process

So, how does composting work? According to Nance Trautmann and Elaina Olynciw of Cornell University, microorganisms break down organic matter, producing heat, carbon dioxide, water and humus in the process.
When composting is done correctly, a pile undergoes three optimal phases:
  1. The mesophilic, or moderate temperature phase, lasts 2-3 days
  2. The thermophilic, or high temperature phase, lasts anywhere from 3 days to several months, depending on what is in the pile
  3. The cooling and maturation phase lasts several months
In the first stage, what are referred to as mesophilic microorganisms quickly break down the easily degradable materials in the pile. The microorganisms’ output of this breakdown is heat, so the temperature in the pile rise. High temperatures in a compost pile are necessary to ensure that the next phase—where thermophilic (meaning "heat loving") microbes replace the mesophilic ones—ensues.
Thermophilic microbes then kill any pathogens that may exist, as well accelerate the breakdown of complex carbohydrates, fats and proteins that exist in the pile. Important to note is that if temperatures in the pile go above 149 degrees Fahrenheit, even the heat loving microbes can be killed, slowing the rate of decomposition.
Because piles can get too hot, aerating, or turning the pile, is essential if the cooling phase is to be reached. The cooling phase is where the high microbial activity of the other two phases is reduced, allowing for the compost to mature and become ready for application.

The Do's and Don’ts: What to Add, What to Leave Out

Besides the process itself, knowing what ingredients should go into a backyard composting operation is essential for a successful outcome.
“Green” (nitrogen rich) and “brown” (carbon rich) materials are required to be in proper balance to ensure that the pile does not become anaerobic. Anaerobic decomposition occurs as a result of an improper chemical balance, mainly a lack of oxygen.
This lack of oxygen necessitates aeration (turning the pile). If the pile is not properly aerated or has too much nitrogen and not enough carbon, rotting and stinking can occur. A compost pile should never smell, according to the EPA.
So, how to achieve this proper chemical balance? Let’s start with the greens. Green materials refer to those that are rich in nitrogen. Some examples of green materials include:
  • Food scraps - Vegetable peelings are a common material produced by households and make a great compost amendment. However, never add animal-based leftovers (fat trimmings, meat, cheese, milk, etc) as the oils and fats are not conducive to a backyard composting operation.
  • Fresh grass clippings
  • Manure - If you have access to manure from horses, cows, sheep, goats or chickens, it is a great compost ingredient because it speeds up the decomposition process. It is not a requisite for a successful compost pile, however. Never use manure from carnivores.
  • Plants and plant cuttings - Just-picked weeds from around the backyard (as long as there are no developed seeds or seed heads) are permissible, as are flower tops. Green leaves from a freshly cut branch work as well (just make sure to shred them).
Brown materials, on the other hand, are rich in another crucial ingredient, carbon. Carbon gives the microbes the energy they need to work. It is useful to shred most brown ingredients so as to lessen the workload for microbes, enabling decomposition to happen faster.
Some examples of brown materials include:
  • Dead, dry leaves
  • Hay and straw
  • Simple paper products - Newspaper, paper and cardboard
  • Crushed egg shells
  • Coffee grounds - tea bags and loose-leaf tea work as well
  • Wood ashes and sawdust - Use sparingly. Wood ashes can make the pile very alkaline, which limits microbial activity, and sawdust can take a long time to break down.

Some Final Tips: Water

According to the EPA, another important factor to keep in mind is the moisture content of the pile, since the hard-at-work microorganisms need an adequate amount to survive. Water also transports nutrients and organic matter throughout a compost pile, which keeps the pile from becoming stagnant.
But how do you tell if water should be added? According to the New York City Compost Project, if you have just loaded the pile with  autumn leaves from the backyard, make sure to add sufficient water to them so that they glisten. Doing so kick starts the decomposition process of the carbon-rich leaves.
Additionally, the NYC Compost Project recommends that "Optimal moisture levels for composting occur when materials are about as moist as a wrung-out sponge—obviously moist to the touch, but yielding no liquid when squeezed."
For advanced-level composting, moisture content instruments are available and can help you to be more precise, although rainfall will often do the trick, as it provides a slow soak that is optimal for a infiltrating a compost pile. For those in a drier climate, however, intentional watering will probably be necessary. Make sure to add water slowly and to turn the pile to incorporate the water so it reaches all sections.

Make It Easy!

To avoid countless trips out to the backyard to dispose of kitchen scraps, put them in an airtight bag and freeze them. This also helps to avoid the smell of old food.
Additionally, freezing will assist in achieving chemical balance in your compost pile. For example, if you have an overload of “green” food scraps from that get-together you had the other night and you do not have the necessary “brown” materials to balance out the pile, freeze the scraps for a while until you have enough "brown" to add to the pile.
Where you live and your particular climate will have a significant effect on your pile, some it occasionally may come down to some experimentation. For more guidance as well as some more advanced composting methods, check out the video below to get started:
