How to select the best site and improve soil for food gardening

Your Site

First thing first, you need some space to grow. Community gardens can be a great way to become more connected with your neighborhood and learn from gardeners of all walks of life. Land in urban areas can be hard to come by-currently Portland Parks and Recreation has a waiting list for community garden plots of around 1000 people-but, you don't need much land to grow a significant amount of food and there is always container gardening.

It's estimated that twenty square feet could feed a family of four and a twelve square foot plot of vegetable could feed one to two people. If you don't have time to grow yourself but have the space, there are several Portland-based businesses that will cultivate your yard for you.

Here are some ideas of where to scope out growing space:

Your Soil

"A nation that destroys its soils destroys itself." – Franklin D. Roosevelt

Soil holds the roots of life. Healthy soil is the key ingredient to a successful garden. Good soil supplies the minerals, microbes, water retention and drainage that your plants need to thrive. So, let's start from the ground up. Get ready to dig in, dirty your hands and expand your soil horizons.

Soil Testing

Since we are in an urban setting, it is important to test your soil before planting edibles. If your home was built before 1978, there is a high chance your soil contains lead from paint particles (the federal government banned the use of lead paint after 1978). Land next to busy roads and industrial areas should have soil tested as well. Soil tests indicate soil fertility and can help you figure out what you need to improve your soil's nutritional content.

Soil Testing Labs

You can do a home soil test, however, these are not as accurate and comprehensive as sending samples to a lab.

Result Interpretation

Soil tests results may be difficult to understand. Visit your local garden store or nursery to speak with an expert who will help you figure out what your soil test means.

Here are some resources on how to read your soil analysis:

Soil Amendments

Once you have an understanding of your soil makeup, supplement your soil with the nutrients your plants need.

Here are some easy approaches you can take to enrich your soil:


Compost! - Use your left over food and yard scraps to complete the nutrient cycle and grow more food.

Buy amendments - There are people all over town who specialize in strengthening soil composition. From fish emulsion to rabbit poop to organic fertilizer blends, there are many environmentally friendly options to choose from. Find a garden store or nursery near you, bring in your soil test, pick employees' brains, and experiment to find out which inputs work for you and your soil.

Cover crop

Especially over the winter or while not growing on a piece of land, use this time to cover crop with plants that will fix nutrients into your soil.

Resources for planting a home food garden

"Cultivators of the earth are the most valuable citizens. They are the most vigorous, the most independent, the most virtuous, and they are tied to their country and wedded to its liberty and interests by the most lasting bonds." – Thomas Jefferson

Planting a garden can be easy as peas. According to the National Gardening Association, 35 percent of American households had some kind of kitchen garden in 2009. Add to that number and help reclaim our food system by growing some vegetables in your backyard or in a container. Figure out the what, where, when and hows of your garden with the following resources:

Seeds

Scrolling through seed catalogues can be an enjoyable experience on its own: the plush colors of a royal burgundy bush bean, the eccentric patterns on a tigerella tomato, the bulbous shape of a lemon cucumber; who knew our staple vegetables could come in so many different shapes, sizes and colors?

Part of the fun of planting a garden is planning what to grow. During a rainy Portland winter day, curl up with a seed catalogue and let your imagination run wild.

Timing is everything. Your ground is ready and beds are made, but before starting your seeds, it's important to know what's best to plant and when in the Pacific Northwest.

Keep Your Plants Healthy: Pest, Weed and Disease Management

Part of gardening is not being in control. Whether you're growing inside or outside, your plants are fair game for sliming slugs, foul fungi and intrepid invasives. Not all unintended garden guests are bad - some insects and plants can complement the health of your crops. If you do see a budding problem in your bed, for the health of your soil, the critters living in it and you, the consumer of homegrown vegetables, it is important to use environmentally sound methods pest, weed and disease management.

Here are some resources for natural or organically approved weed/pest/disease management:

Composting at home

Metro provides extensive online educational tools for composting at home, as well as a downloadable "Make your own compost" booklet and a composting demonstration site showing a variety of different composting set-up options.

The OSU Extension Service website offers an informative page on how to compost at home.

Many of the organizations that offer gardening instruction also offer educational resources for composting. See the "I want to…grow my own food" section for resource links.

Commercial composting

With the Portland Composts! program, businesses in the City of Portland can now contract with waste haulers to collect food waste and food-soiled paper for composting.

Better Together Garden at City Hall

The Portland Multnomah Food Policy Council asked Portland City Council to create a garden at City Hall to inspire Portland residents to plant their own gardens and an extra row for the hungry. The Commissioners passed the Better Together Garden resolution on Earth Day, April 22, 2009.

Elm Court Loaves and Fishes, five blocks from garden, will receive the harvested produce and fruit. The senior meal site serves 150 on-site and delivers an additional 250 meals every day.

The Better Together Garden includes 700 square feet of vegetables and is surrounded by columnar apples, a fig tree, blueberries, lingonberries, currants, and strawberries. The garden was installed over four days by community volunteers and all labor and materials were donated. The project was made possible by the generosity of the following businesses:
