This is our Doomsday Radish page. It gives instructions on how many radish plants are needed to feed one person for a year.
One cup of radishes is about 20 calories. On a 1200 calorie diet it would take about 60 cups of radishes to survive. It would take about ten radishes to make one cup. This would be 600 radishes a day or 219000 radishes a year.
It would probably not be feasible to plant radishes to survive on. But they can be grown almost year round where the ground does not freeze and are usually ready in about 25 to 30 days.
You cannot can radishes. You can slice them up to dry, but they probably would not taste very good. The best way to eat radishes is fresh. Once pulled from the ground you have about 24 hours to eat before they start to get soft.
We have gotten seeds for a rather large radish called the Sakurajima
Giant Radish (shown to the right). We are going to plant these for eating and seed
production. We will have video of this as we go along. We will start
these sometime in February of 2019. We do not have these for sale at this time.
All of the variety information on the David's Garden Seeds® website, including the days to
maturity, color and size are based on data from tests done at specific
locations. Many factors, including geographic location, daytime and
nighttime temperatures, the availability of plant nutrients, many unknown climate factors and insects/pest interact to determine a variety's
performance. For information on which varieties will perform best in
your area, we recommend that you contact your local county extension agent or a Master Gardener.
David’s Garden Seeds®, gardening is our passion. We provide top quality,
non-GMO seeds so families can learn about gardening and love it. In turn, we
hope they will pass this passion down to their children and
grandchildren, teaching them to grow delicious food, fresh herbs and
