Sustainable, Earth-Friendly Gardening Tips from the Pros
BY THE CIVIL EATS EDITORS
One of the biggest challenges most home gardeners face is simply getting started. And even well-versed growers can find new ways to improve their gardens. We spoke to a number of experts to gather their best tips for growing food in a productive, sustainable, and climate-friendly way. In addition to Sally Morgan, we spoke with Karen Washington of Rise & Root Farm in upstate New York, Jenny Wechter of Eastie Farm in Boston, Jasmine Jefferson of Black Girls with Gardens and gathered some tips from Emily Murphy’s new book, Grow Now. Read on for suggestions and inspirations, and if you have any suggestions to share, we would love to hear from you—email us at members@civileats.com.
Take a no-dig approach. To protect your soil construction and avoid releasing the carbon the plants have stored in the ground, disrupt your soil as little as possible. When you plant your starts or seedlings, dig the smallest hole you can to fit what you’re planting. ~ Emily Murphy
Plant cover crops. After a year of growing and harvesting, the soil needs time to recover. Cover cropping with plants such as legumes like vetch and red clover improves soil health, prevents erosion, and helps with weed and pest management—among many other benefits. Look at it as putting the soil to sleep. Once planted and given time to grow, the cover crop gets reincorporated back into the soil, enriching it once again with nutrients. There are a number of different cover crops one can use, depending on your particular climate and temperature region. Usually, your local extension agent can help with the right selection. ~ Karen Washington
Amend your soil with compost. To sequester carbon and feed your soil ecosystem, put compost, or decomposed organic materials, around the plants you’re growing. In your compost pile or bin, layer one to two parts brown materials like dried leaves or twigs (which contain carbon) with one part green materials like vegetable scraps, coffee grounds, or crushed eggshells (which contain nitrogen). Wet the layers occasionally. Turn the mixture regularly. When the mixture is fluffy and chocolatey brown, it is ready to be applied to your beds. ~ Emily Murphy
Avoid peat-based potting soil. Peat-based soil is generally non-renewable, and harvesting peatlands releases carbon dioxide, contributing to climate change. Coconut coir, composed of the coconut husk to inner shell, which is often discarded as waste, is an alternative. ~ Jasmine Jefferson
I also have a big thing about peat. Here in England we have a big campaign to stop using peat in gardens, in potting compost, etc. In the States and in Canada, a lot of peat is dug up to make potting soil, and peat in the ground is our best weapon against climate change. It locks up so much carbon, and I get so frustrated when I see gardeners using peat because they think it's perfect, weed-free, and cheap. ~ Sally Morgan
Responsibly deal with weeds. Some consider weeds to be simply unwanted native plants. While people often want to remove weeds for aesthetic reasons, they are conditioned to the land, grow well with minimal intervention, and can be beneficial in terms of encouraging pollinators and supporting healthy soil. Consider carving out areas where weeds and other native plants can grow. If the weeds must go, simply uproot as much as possible and pour boiling water or vinegar onto the spot. Let it sit for a few days untouched before adding compost and replanting. ~ Jasmine Jefferson
Rotate your crops. Another good technique to use in the garden is crop rotation—never plant the same crop in the same spot each year. Rotating different plant species into each location helps with pest and weed management and offers diversity that helps with soil health management. ~ Karen Washington
Foster biodiversity. Landscapes and gardens planted with a diverse range of native perennials, edibles, and select ornamentals foster biodiversity and provide a plethora of ecosystem services from which we all benefit. A diversity of plantings creates a resilient, robust system that requires fewer inputs. ~ Emily Murphy
Manage your pests. Since nearly every pest has a predator, infestations are a sign that an ecosystem is out of balance. If a garden has too many aphids, for example, it doesn't have enough ladybugs and likely needs new types of plants that encourage the red-and-black lady beetles, which feast on aphids. Aim for the least amount of intervention possible to manage pests, such as planting flowers that attract predators or adding bird feeders. The next step would be to wash any infested plants with a hard stream of water before removing any remaining pests by hand. As a last resort, a plant-based solution such as neem oil may be used to treat infestations without harming other insects, pollinators, or birds. ~ Jasmine Jefferson
Avoid synthetic fertilizers, pesticides, and herbicides. Producing synthetic fertilizers creates significant greenhouse gas emissions, and after they are applied to the land, they run off and pollute waterways. Instead, make your own fertilizer by creating a tea-like substance out of compost or manure. Add a few handfuls of compost or manure to a bucket, then fill the bucket with water and let the mixture infuse like tea. After 24 hours, strain off the liquid. Apply the nutrient-rich tea to your garden beds once or twice a year, or when the plants look like they need it during the growing season. ~ Emily Murphy
Watch your watering (in dry places). Be mindful of water use, don't use more than you need, and reuse water whenever possible. Rain barrels are a great way to collect rainwater that can be used in the garden. Position hanging plants over other plants to capture and reuse excess water. Irrigation systems are also helpful to ensure that plants receive the water they need without overwatering. ~ Jasmine Jefferson
Grow companions for your plants. Plants are like people in many ways: Not only do they have needs, but they have preferences. When certain plants are planted together, they help each other thrive—these are called companion plants. Basil and tomato, for example, are a common companion pair. Rather than having one crop growing—which limits mutually beneficial relationships among different plants, and lends itself to disease and pest susceptibility—at Eastie Farm we intentionally grow different types of vegetables around particular herbs and flowers (such as marigold and borage) that support each other. Getting to know what each and every plant likes and needs is always the first step to taking good care of an edible garden. ~ Jenny Wechter
