25 tips for urban gardening

  • 25 tips for urban gardening

    Ancient civilizations thrived in relation to their proximity to food sources thousands of years before the global food trade our world relies on today. Eridu (present-day Tell Abu Shahrain in Iraq), founded in Mesopotamia along the Fertile Crescent’s Euphrates River around 5400 B.C., was believed by the Sumerians to be the first city in the world, and integrated urban farming into the city’s design itself. Examples throughout history show the rise of new civilizations in direct proportion to food and water sources.

    As trade routes opened up around the world, farmers could specialize in raising specific foods to trade with other specialists in different regions. The Industrial Revolution in the 18th and 19th centuries further bifurcated cities and food sources by automating farming processes, dramatically increasing production, and making the international transportation of fresh foods a reality.

    Since then in American history, proximity to food sources has fluctuated. During World War II, private residents started Victory Gardens that by 1944 accounted for 40% of U.S. produce. The country’s community gardens—neighborhood plots where people work together to raise food—have spiked in the past decade, with a 44% jump in city garden plots between 2012 and 2018. Community gardens springing up in empty lots in cities across the country offer inspiration for fresh approaches to urban revitalization in places like Detroit, where 23,000 residents participate in urban gardens, 1,500 residents have private gardens, and 16.75% of the city’s land is considered vacant.

    Urban gardens can provide nutritious resources for residents who otherwise live in food deserts (areas without convenient access to fresh, whole foods, usually because of a lack of grocery stores and farmers markets, often in impoverished parts of cities or remote locations), provide children and adults with an education in self-sufficiency, and reduce food costs for individuals and families.

    For those interested in getting into urban gardening, Stacker used a variety of agriculture and gardening resources to compile a list of 25 tips to get you started—from plant selection and garden location to essential tools for the job.

  • Plan your plot

    An urban garden can occupy a shared, community plot of land, a section of a yard or rooftop, or a container on a fire escape or windowsill. Most edible plants are hungry for sunlight, so look for a south-facing area for your plants.

  • Get the right tools for the job

    The only major things one needs to start a garden are soil, a vessel or area to plant in, and seeds. Many gardeners further opt for terra-cotta pots, compost (more about that later), gardening gloves, a watering can, organic fertilizers, and lumber for raised beds. While there is no shortage of beautiful gardening products, it’s wise to start with a minimal investment—plants aren’t picky with appearances.

  • Grow appropriate plants

    The USDA Plant Hardiness Zone Map breaks down growing seasons for every part of the United States (last updated 2012). Zone numbers correspond to when different plants can grow in a region, and seed packets list their zone numbers to help gardeners determine what varietals will do best in specific climates.

    Once you’ve figured out your zone, it’s time to pick plants that thrive in urban landscapes. Non-edible varieties include zinnias, daylilies, and coneflowers; if you’re growing plants to eat, look for varieties that don’t need a huge amount of space (this is probably not the best time to put in a pumpkin patch). If you move a lot, don’t pick perennials that you must tend to year after year: When you sign a new lease next fall, you’ll mourn the loss of that asparagus bed.

  • Grow what you eat

    If you will grow edible plants, one of the biggest mistakes you can make is growing food you don’t normally like to eat. There’s no reason to grow 15 summer squash plants if you can’t stand ratatouille, or cucumbers if you never eat them. Focus on foods you naturally gravitate toward and start easy. Basil is great for sunny spots and makes a delicious pesto, while garlic can grow virtually anywhere and can be replanted each year. Other easy crops for first-timers are tomatoes, onions, peas, and carrots.

  • Raise your beds

    Raised beds are a great, no-till approach to gardening. They also circumvent the potential for harmful toxins to leach into your plants. If you plan to install raised beds, there are a lot of prefab beds that can be purchased online or from garden stores, or you can build your own. Beds should be at least half a foot tall for plants with deep roots or for root vegetables like carrots. To fill your raised beds, lay cardboard and newspaper over the ground then pile up leaves, sticks, compost, manure, mulch, and finally a thin layer of dirt. Seeds can go right in—but for raised beds that involve lots of decomposing layers, steer clear of root vegetables in the first year until you’ve got deeper layers of dirt to work with.

  • Test your soil

    Any soil you want to grow food in ought to first be tested first for pH and nutrient levels, as well as for contaminants. City dirt, in particular, is likely to have absorbed toxins that you don’t want ending up in your vegetables. Local extension offices, as well as national soil-test centers, can provide results on everything from pH and nutrient levels to potential toxins.

    If soil is uncontaminated but has low or high pH or insufficient nutrients, this can be easily remedied with fertilizers, compost, and other soil amendments. If soil tests positive for toxins, there are still plenty of options for urban gardening in containers.

  • Make dirt

    Making dirt is as easy as composting food scraps from your kitchen table. Other items that can be broken down include shredded paper, cardboard, and newspaper—and, depending on what household cleaners you use at home, dustpan refuse and whatever you suck up with your vacuum cleaner.

    City dwellers can keep a vermicompost bin under their kitchen sinks, a tumbler in the yard, or bring scraps to a community garden in exchange for a share of fresh soil in a few months (if you’re worried about smell, keep a lidded Mason jar or freezer bag in your freezer and add to it as you go—bring full containers to community gardens).

  • Grow up

    Small spaces don’t have to mean limited garden space. Vertical gardening offers flexibility for growing plants along the interior or outside walls, or up arbors in the yard or on rooftops. Tire towers for potatoes, felt wall hangings for herbs or loose leaf greens, and trellises for peas, beans, and squash can all offer big yields in tiny spaces.

    Shelves can be another great option for plants, allowing you to stack them along an outside garage or home wall, or up a wooden fence in your yard.

  • Embrace every season

    Four-season city dwellers can enjoy the respite of winter and scale back the foods being grown, or use colder seasons to grow herbs indoors on kitchen counters. In places like California, urban gardeners can study when to plant crops like artichokes and garlic for year-round plants.

    Late summer in most places is a perfect time to re-plant salad greens, carrots, and zucchini; while December is the best month to plant garlic sets for the following spring.

  • Rethink your fish tank

    Aquaponics is a method of gardening in which fish provide the nitrogen plants need so you can grow things indoors without a lick of soil or fertilizer. All it takes is a fish tank of any size, a tiny pond pump to pull water out of it, and a grow bed with pea gravel and seeds (as well as an indoor grow light to keep on between eight and 12 hours a day).
