Tasty Radishes

Radishes (Raphanus sativus), with their zingy flavor and firm texture, are a vegetable I have grown to love. This member of the Brassicaceae or Cruciferae (Mustard) family, which also includes garden favorites such as Romanesco and Cauliflower, come in many varieties. The varieties of radishes are classified by their planting times (early, mid, or late), their root shape (flat, oblong, round, half-long and long), and their color.

There are some specific varieties to make note of in the radish world. Easter egg radishes are easy to spot as they don’t just come in the traditional reddish color of a radish, but in whites, pinks, and purples. There are also other varieties of radishes that come in black, green, and some that even resemble a watermelon.

Another notable radish is the Japanese Daikon. This radish is white in color and very long, with some even reaching over a foot. The Daikon is known as an oilseed radish. These are becoming progressively popular as a cover crop and can improve soil conditions, as well as create a nice place for early planted vegetables the following spring. Plus, Daikons go great in a batch of kimchi!

History

Radishes are thought to have originated in Southeast Asia due to the fact that this the only area that has wild varieties growing in it. The cultivation of different varieties is thought to have occurred in India, central China, and Central Asia. Radishes were historically recorded by the 3rd century BCE and show up in Chinese and Egyptian culture. As the millennium rolled around the Greeks and Romans were growing several varieties of the radish. Later the crop spread through Europe and was one of the earliest crops introduced into the Americas.

Raising Radishes

This cool season vegetable is easy to grow but prefers to steer clear of the summer heat. It’s best to plant them 4 weeks prior to the last expected frost date in your area if you are doing a spring planting. If you decide to do a fall planting, sow radishes in late summer or early fall. The nice thing about radishes is that they can be planted later than other root vegetables and you can plant every 2-3 weeks in the cool months to allow for a continuous harvest.

As you plant your radishes sow the seeds approximately 1” deep and 1” apart. Then thin your radishes to 2” apart if they seem crowded, as crowded radishes don’t grow well. Another thing that creates a poor crop is too much shade. Make sure you plant radishes in full sun, otherwise you will get large leaves and little root development. Water your crop consistently to keep the soil moist, but don’t allow your radishes to become waterlogged. Lack of water, just as excessive heat does, will cause your radishes to bolt prematurely.

Just like most garden produce, radishes are susceptible to pests and disease. One pest that can afflict your radishes is the cabbage root maggot. These pesky pests live in and under the soil and are difficult to spot. Your best bet at combating them is prevention. Rotating your radishes, tilling your garden between seasons, keeping your garden neat and tidy, and even practicing later season planting techniques can help prevent an infestation. Some nurseries offer nematode control. Check with a local one in your area to see if you can incorporate them into your soil foodweb. Nurseries may also offer sticky traps to place in your garden to trap the adults before they lay eggs. Just make sure nothing in the traps is toxic.

Harvesting and Storing

As soon as your radishes are mature, which can be 3-4 weeks after planting, pull up your root vegetables, otherwise leaving them in the ground can cause deterioration. Once harvested, cut off the tops and wash and dry the tops thoroughly if you plan to use them. Both the root and the greens can be used and stored in the refrigerator. However, greens usually only last 2-3 days, but the root can last up to one week. I find it best to either leave the root portion unwashed and stored in the refrigerator in a plastic bag until ready to use or to wash them and keep them in a glass container filled with water.

Nutrition

After harvest is the time to enjoy this wonderful root vegetable. If you’re wondering if radishes have any health benefits, they indeed do. In one cup (116 grams) serving of radishes, you will be provided 19 calories, 0 grams of fat, 1 gram of protein, and 4 grams of carbohydrates (of which 2 grams is dietary fiber). Radishes are an excellent source of Vitamin C and they also provide Vitamins K-1 and all the B’s (except B-12) and the minerals calcium, copper, non-heme iron, magnesium, manganese, phosphorus, potassium, selenium, and zinc.

Radishes are also a good source of phytochemical compounds. These compounds include sulforaphane from the isothiocyanate group of organosulfur compounds. Found in other mustard family vegetables, sulforaphane has cancer prevention and anti-inflammatory properties. Radishes also possess additional phytochemicals including indole-3-carbinol which also works to prevent cancer, along with zeaxanthin and lutein. These phytochemicals can reduce inflammation and help detoxify the body.

To enjoy all this nutrition, you can fashion some amazing radish recipes that range all the way from the super simple to the fantastically creative. While radishes are quite delicious with just a bit of warmed butter drizzled over them and a dash of salt, or sliced and added to your favorite fresh garden salad, there are other ways to prepare radishes for your next meal. This recipe is one I typically use when I have Daikon radishes. You can substitute any radish in the recipe, it will just take a whole lot more of them.

Radish Cakes

Ingredients:
2 cups grated Daikon radish
2 teaspoons salt
1 clove garlic, smashed and minced
1 small red onion, finely chopped
2 eggs, beaten
1 cup almond flour
1 teaspoon freshly ground black pepper
1 teaspoon paprika
1 teaspoon hot sauce
Enough butter or ghee to fry your cakes

Form mix into small patties (you will get about 8-12 depending on patty size)
In a large skillet heat oil over medium high heat

These radish cakes are amazingly flavorful and can be served with any meal or all on their own. A small dollop of sour cream goes well with them, as does some fresh sliced avocado.

Another quick and easy recipe you can whip up using radishes is a flavorful butter. Check out the following recipe.

  1. I just wanted to say, since I started following Charles Dowdings ”No Dig” videos and bought a book or two, I am able to grow and gain a larger yield of Annuals since following his methods togehter with our typical Permaculture practices.

    For Radishes, you do not need to follow typical spacing guidelines, you can sow 5 seeds in one module, thin to four plants and plant out when you want to – you can make spacing between these modules a little bigger than typical spacing since there will be Four plants growing in the space of One.

    What would one rather have? Four medium sized radishes in the space or One large one?

    This is how simple it is; Near harvesting time, you merely find the bigger bulb and twist it out, do this in the whole row per planted module and get one radish per module for that day and follow on weekly until all four plants in each row are finished.

    Therefore Six plantings in one row yielded 24 Medium radishes as opposed to 6 Large radishes.

    Charles has spent the last 34 years growing Organically in no dig systems around the world and has a whole list of plants that you can use with this method, try check him out, you will also have to learn how he crates the beds to grow this way.

  2. Hi Jeff-

    This is great info! I really appreciate you sharing this. I will check it out. And this gives me something new and fun to try with my next plantings! Thanks so much for reading and posting! -Bobbi

  3. Is it OK to prop up my daikon radishes in tomato cages? They over wintered from last year but they took gradually took over half of my 4′ by 8′ raised vegetable bed. So I propped/tied them in tomato cages but they don’t look too happy. They are not wiltng but they are quite confined from whereto what they used to be. However, I found several different plants that had been taken over by the daikons.
