Edible Garden Basics: How Much Food to Grow Per Person

By Catherine Winter

Let’s face it: a lot of people are freaking out right now over the possibility of coronavirus-related food shortages. With grocery stores being emptied at record speeds, many are buying vegetable seeds in the hope of growing food for their families this season. But that opens a new issue to deal with: how much food to grow to ensure that every family member is fed?

Several Factors to Consider

Many factors need to be taken into account here, including how many people are in your household, their ages, and what they’ll actually eat. As mentioned in previous articles, sure—your land might be ideal for growing acres of one particular species (like zucchini) but it’ll be a disappointing waste if nobody will eat it.

Additionally, you’ll need to consider whether you’re just growing food to eat fresh, or if you’ll be preserving some to eat over the winter.

Let’s take a look at how much food you’ll need to grow to feed an average family of four, consisting of two adults and two adolescent children. From this average, you can make adjustments to suit your own family’s individual needs.

How Much to Plant to Feed a Family of Four

Families come in many different shapes and sizes, so you can adjust the amount (and species) to grow based on your crew’s unique needs.

For example, if nightshade allergies are prevalent in your household, skip the tomatoes and peppers and add more green beans, root vegetables, and squashes. If y’all love spinach, grow double that amount, and skip the stuff you don’t like.

You’ll also need to work with the space you have available to you to determine which species will thrive there. If you have a big sunny backyard, you’ll be able to grow a lot, very easily. Others may have to adapt to smaller outdoor spaces, using fences for growing beans and peas, upside-down hanging bottle planters for tomatoes and herbs, etc.

Additional Inspiration from World War 2 Victory Gardens:

This pamphlet, Dig For Victory: Grow for Winter as well as Summer, was released by the UK Ministry of Agriculture in the early 1940s. People grew all manner of food in their back (or front) yard “Victory Gardens“, and there’s no reason why we can’t do that again!

The images, although blurry (sorry) offer helpful guidelines on garden layout, as well as number of plants per row. It also tells you when to sow which species, and when they’re ready to be harvested.

Remember that if you’re planning to can/preserve food for the winter, you’ll have to grow approximately double the amount suggested here, of the foods you’d like to keep around.

Tomatoes, and foods that can be pickled are the easiest to can. For low-acid foods such as peas, beans, potatoes, etc., you’ll need to invest in a pressure canner in order to preserve your food safely. As an alternative to pressure canning, you can freeze your harvest for up to 6 months.

In addition, remember that you leave green beans to mature on the vine in order to have large dry beans to add to soups and stews over the colder months.
