Calculating the Savings in Growing Your Own Food

October 1st, 2011 at 08:03 am


Most will agree, a garden is not complete without tomatoes.

We all know that growing our own food offers multiple benefitsófor our health, our taste buds, and our pocketbook. But how many of us know how much weíre actually saving?

For the past few summers, Iíve conducted a little experiment to see just how much I would save by growing veggies myself versus buying their supermarket counterparts. You may be surprised at the results!

Why Grow Your Own?

Before getting to the numbers, letís review the many benefits of growing your own food. They include:

Personal satisfaction: When it comes to self-sufficiency, there is nothing more elemental than being able to feed oneself. I love the early-evening ritual of wandering down to the vegetable garden, colander in hand, to pick whatever has ripened and prepare it for my dinner that same evening.

Lessening your environmental footprint: By reducing your reliance on foods grown far away and trucked hundreds or thousands of miles to your local grocery store, your food consumption contributes less to smog and global warming. By growing your vegetables, youíre also doing your part to reverse the globalization of the food supply.

Superior taste and freshness: Homegrown fruits and vegetables simply taste better than produce thatís been allowed to ripen in trucks during transport and sit on store shelves before youíre ready to eat it. Even if youíre not a verifiable foodie, the taste, flavor, and freshness of homegrown produce is reason enough for many gardeners to devote a portion of their yard, patio, or terrace to growing vegetables.

Better nutritional value: Because less time elapses between harvest and consumption (say, about an hour when I harvest my own produce compared to days or weeks when I buy it in the supermarket), homegrown vegetables deliver higher nutritional value. And if you choose to grow your produce pesticide-free like I do, youíll get the added health benefits of consuming organic produce at little-to-no extra cost.

But for the budget-minded among us, a fifth important benefit of growing your own food isÖ

The ability to reduce your grocery expenses: In todayís challenging economy, nearly every consumer is looking to save a few dollars wherever they can. Growing your own vegetables can substantially reduce your grocery bill throughout the summer. If you freeze or can your surplus, you can extend your savings into the winter months.

The Economics of Homegrown

This was the third season I tracked my gardenís output, not only by the pound, but by its monetary value.

My garden plot is modest in size, about 120 square feet. It was not intended to feed a large family, although the inevitable surplus is freely given to friends and neighbors. In its current form, itís L-shaped (to detour around a small juneberry tree) and located in my front yard, to take maximum advantage of sunlight.

Die-hard gardeners can spend lots of time experimenting with heirloom varieties, growing plants from seed, and researching the best soil amendments, fertilizers, compost, and mulch covers. Yet you can fumble along, make mistakes, and still wind up with a respectable harvest, provided thereís ample sunlight and adequate watering.

Due to my own laissez-faire attitude about plant diseases, my garden is succumbing a few weeks early to blight and powdery mildew. With the harvest about 95 percent in, Iíve tallied up my pickings for the season.

To determine their monetary value, I checked the prices of comparable produce at Shop Rite, my grocery store of choice. Whenever possible, I used prices of Shop Riteís organic produce. But for about half of what I harvested, I couldnít find organic equivalents and was forced to use the non-organic price in my comparison. Because produce prices fluctuate regularly, I used an average of Shop Rite prices I found throughout July and August, at the height of my gardenís production.

Hereís what I grew and harvested this year, ranked by its dollar value:




2011 total monetary value: $330.08
2011 total expenses: $21.78
Net savings: $308.30

How do these numbers compare to previous years? In 2009, I grossed $148 in produce from a somewhat smaller-sized garden, but ended up with -$222 after factoring in my Ďstart-upí expenses which included a pricey, six-foot-high roll of wire fencing and metal posts (essential to exclude deer).

In 2010, I enlarged the garden (since I had leftover fencing) and harvested more, growing $515 worth of food ($429 after expenses). I attribute some of the increase to a more concerted effort to harvest wineberries daily during the month of July, as they ripened. The wineberries, which grow naturally in my backyard, are an invasive Asian bramble that produces berries that look similar to a raspberry. Since youíll never find them in a store, Iíve used raspberry prices for comparison when calculating their monetary value. (And you know how expensive raspberries are in the store!)


Acorn squash on the vine

Last summer, I hand-picked 39 cups of wineberries, which really boosted my Ďgardení productivity. I planned to do the same this summer, but lost my enthusiasm after finding a tiny tick embedded in the skin between my fingers. I don hip boots sprayed with DEET for wading into the brambles as protection against ticks (Iíve had Lyme disease twice) but hadnít counted on picking one up on my hand. So I settled for about nine cups of berries picked from the relative safety of the periphery of the thickets.

This yearís garden is pretty much spent, but I take comfort knowing Iíll be enjoying my tomatoes, wineberries, kale, basil, and zucchini (in the form of soups, stews and quick breads, and on my breakfast cereal) in the cold winter months to come. I canít wait until next spring, when Iíll be planting soybeans for the first time.

    Thanks for the chart! Did your values surprise you? I am surprised that kale and broccoli came out so low...doesn't seem worth the effort. But tomatoes, on the other hand.... You are inspiring me to get back to my tomato growing next year (which I skipped the last two summers, as I was away half of each summer visiting my mother in Los Angeles).

    You only got 6 zucchini from 2 plants? I didn't have a garden this year because I was pregnant, but the previous two years, I would get 3 zucchini from each plant every other day or so. Wonder what the difference is?

    I think the difference is pollination. Although I was hand-pollinating. You always get a lot more male flowers than female, and if, when the female flower blooms, there are no male flowers in bloom, that = no fruit. The bloom only lasts a day. Iknow, Iknow, these things are complicated.

    The kale and broccoli were low becus i only had 2 of each, and the kale really got zonked my slugs.

    We have always grown a big garden. Tomatoes are my favorite. I eat tomato sandwiches, with Miracle Whip. I have been unemployed, and I can say that it was not fun. I wish you the best to find employment.

    Thanks for sharing your garden info with us. I'm contemplating a container garden next year in the condo courtyard. Start-up costs being the hurdle one must jump. I was wondering about watering issues. Did you factor in watering costs?

    No, my outdoor water is free. It comes from my well.

    I love your garden photos, and I truly believe that home-grown food leads to the best insurance of safer and healthier options for all of us. Thanks for sharing!
