Garden Calculator

Our garden calculator computes the per pound price or per bushel price depending on how the items are sold in general. Usually lettuces, greens, and radishes are sold per bushel where most others are sold per pound.

HOW TO USE? Select the vegetable of your choice and then click CALCULATE.


How did we calculate?

According to the National Gardening Association, the average cost of maintaining a vegetable garden is $70 per year (fertilizer, watering, basic supplies) and the average food garden is below 10 square feet. We decided to use 5 square feet as a safe estimate for urban gardeners. Five square feet could be a 2×2 box plus one square foot container or five containers.

Grocery store prices are based on actual per pound prices at local Los Angeles stores.

To Calculate:
We took $70 and divided it by 365 days (= $.19), multiplied it by the average number of days a crop grows in a garden and we then added the cost of the seeds. We divided this number by the average yield in pounds for this growing period to arrive at the per pound (or bushel) cost.

Calculations for blackberries and blueberries assume you have the plant. Since the cost of these plants vary so much, we did not include it in the per pound price.

If you have questions or comments, let us know – write below or email us. This calculator is to use for entertainment and cocktail party conversations. More than anything, we encourage you to grow your own organic food, it’s good for the earth and for you. Change the world one garden at a time. Say yes to fresh food, say no to chemicals and GMO’s in your food!

Happy Gardening!

The savings are even greater if you attend a seed swap event and have a watter butt to save rain water, blackberries grow wild with ease here in the UK, and if you compost in a wormery you getliquid fertilizer free from the worms.

I have a backyard garden that is about 40′ x 60′. Because I grow heirlooms almost exclusively and do seed saving on at least half of my plants, get free mulch from a tre trimmer and horse manure from a stable, and the water is paid by the landlord, I figure I save several hundred dollars a year by growing my own fruits and veggies. I have planted a 40′ x 20′ food forest with several fruit trees and grape vines. It is not bearing fruit as yet (except for the Satsuma Plum) but in 5 years, I expect to be able to harvest enough fruit for myself and my friends to eat and can each year. Funny, my mom grew up in the country and couldn’t wait to move to the city. All of her children have either gone back to the country or become urban farmers :).
