Spanish Black Radish Native Habits
Spanish black radishes (Raphanus sativus) are heirloom radishes that are significantly more peppery than the rosy red radish. They also take about two to three times longer to mature than the common red radish. There are two varieties: a round one that looks much like a black turnip and a long one, which is cylindrical and can get to about 8 inches (20 cm.) long. The long variety is more pungent than the round but both have flesh that is crisp, white and peppery. To quell some of the spiciness, remove the black peel from the radishes.
Spanish Black Radish Distribution
Native to China, where wild forms can still be found today, spanish black radish
was one of the first vegetables to be traded along the trade routes from Europe to Asia. Round Black Spanish is one of the oldest radishes in cultivation dating back to the 1400s in Europe and early 1800s in the US.

Spanish black radish Propagation with Seeds
Planting Spanish black radishes is easy and can be done directly in the ground all summer. Beautiful fresh turnips can be harvested quickly with just a little ground and/or soil mixture and regular watering. Spanish black radishes’ seeds are sown between May and September/October, depending on the climate.
Plant the seeds directly into the place where they will grow.
Leave a furrow ½ to 1 inch (2-3 cm) deep.
Sow regularly, planting about one seed every 1¼ to 1½ inches (3 to 4 cm).
Cover the furrows and do not press down the soil too much.
Regular watering, drizzle.
After the seeds germinate, thin them out. This means removing the weakest buds and keeping only the most vigorous ones, at intervals of six to eight inches (15 to 20 centimeters).
Remove weeds and make sure the ground is free of weeds.
Periodically break the surface gently with a small hoe to allow the water to reach the roots.
You can also choose to sow Spanish black radishes in Garden
boxes, mix the soil and water them regularly. This will allow you to nibble delicious Spanish black radishes straight from your terrace or balcony.

Temperature and Humidity Care
Optimal growing temperature for Spanish black radishes is between 18 and 24°C (65-75°F).

Spanish Black Radish Varieties
Here are some of the black radish varieties to look for:
Round Black Spanish. In French they are called Noir Gros Rond D’hiver. A large radish that has been grown at least since the 1500’s, the Round Black Spanish may grow to five inches across. The almost nutty flesh may be eaten raw or cooked. The thin skin makes for dramatically colored round slices. Days to maturity: about 55.
Long Black Spanish, or, in French, Noir Gros Long D’Hiver. Growing to an impressive nine inches long, this slender heirloom radish can be sown all the way into mid-autumn.The flesh packs some firepower.
Round Black. A close relative to the Spanish black radishes, this American heirloom matures in about 35 days, so can be sown in early fall for quick harvest and subsequent storage. Grows to about four inches in diameter.
Nero Tondo. Another black radish close to the Spanish black, this variation seems to resist hot-weather bolting better than any other. So if your weather heats up quickly in late spring, the Nero Tondo may be the best choice for consistent texture and flavor. Maturity in 50 days and can be considered a summer black radish.
Russian Black. Native to the some of the coldest growing conditions imaginable, the Russian heirloom black radish can germinate at close to freezing soil temperatures and forms round mature roots in quite cold soil. In warmer zones, try sowing in fall and harvesting in spring.
Spanish Black Radish Common Pests/Diseases
Though Spanish black radishes
are relatively trouble free, particularly when they’re grown in colder weather when pest activity is generally low, there are a few usual culprits to watch out for.
Flea beetles are common but damage is not usually fatal.
Flea beetles – Flea beetles feed on the leaves of all brassicas. Small holes in the leaves are the tell-tale sign. They tend to go for younger plants so transplanting from indoors is a good way to avoid them.
Slugs – Slugs can still be active even when it’s cold so keep an eye out for them.
Cutworms – Cutworms, which are the larvae of moths, are awful little blighters. Protect the base of the stem by surrounding it with a plastic plant pot with the bottom cut out.
Aphids – Aphids can also be a problem for radishes so keep an eye out for them. They’re very easy to spot on the undersides of leaves.
Harvesting Spanish Black Radish
Spanish black turnips take a little longer to mature than spring turnips, but they tend to grow taller and larger. Once you see the top sticking out of the soil, your Spanish black turnips are ready to harvest. Gently pull your Spanish black radishes out of the ground, or dig around them and pull. Be sure to harvest them when they are ripe, otherwise they will become woody or spongy.
Store Spanish Black RadishSpanish black radishes
can be refrigerated at 32 to 40 degrees Fahrenheit for up to 3 weeks. Make sure to cut off the tops before storing the Spanish black radishes, as the leaves can cause too much moisture. You can also fry them on a plate.
Spanish Black Radish Companion Plants
Plant Spanish black radishes near beans, beets, celeriac, chervil, cucumber, lettuce, mint, parsnip, peas, spinach, squash, and tomatoes. Avoid planting near Agastache or potatoes.
