Customer Reviews
I planted the Runder Schwarzer radish seed tape in my Delaware garden in mid September. Harvest time was late October. This was my first crop of this radish and it won't be my last. While I grow several varities of radishes I found the Runder's to be a well suited root crop to use in my venison stew. The Runder added a slightly spicy and earthy flavor to my stew. I can't wait until I can plant the spring crop!
I am growing this variety of radish side by side with the French Breakfast radish. This one has not developed a radish yet, but the green leaves are HUGE. I have been enjoying the French breakfast radish for weeks now and it is lovely to grow, harvest and eat. By the way, I planted these at the end of July...We are in zone 5b here in central new york. This is considered a fall planting....
Thank you for sharing your feedback. We’re glad to hear your French Breakfast radishes are doing well, though we’re sorry this one hasn’t developed roots as expected. Different radish varieties can sometimes respond differently depending on weather, soil conditions, planting depth, etc. Please feel free to email us with more details about your growing conditions and, if possible, include photos so our team can help you troubleshoot. As always, our products are backed by our full guarantee. We want you, our customers, to be 100% satisfied with the seed, plants and supplies that you purchase from us. If anything you buy from Territorial proves to be unsatisfactory, we will either replace the item (if available) or refund the purchase price, whichever you prefer (for up to 1 year from purchase).

None of the seeds I planted germinated. Other radishes in the same container (French Breakfast from 2023) germinated just fine. I have replanted in a different container but it is too soon to expect germination. For what it is worth, none of the Coventry carrot seeds I planted in three different containers germinated. My Burpee Short and Sweet carrot seeds from 2023 were fine.
So sorry to hear that! Runder is a variety that tends to do better in the fall, so you may want to try a late summer/early fall sowing for a fall harvest. We do germ test all of our seeds and to ensure we sell only top performing crops, we have established germination standards that are higher than prescribed by the Federal Seed Act. Our minimum germination standard for radishes is 80% and the most recent test for this variety passed at 80%. As always, our products are backed by our full guarantee. We want you, our customers, to be 100% satisfied with the seed, plants and supplies that you purchase from us. If anything you buy from Territorial proves to be unsatisfactory, we will either replace the item (if available) or refund the purchase price, whichever you prefer (for up to 1 year from purchase). You can also reach out to us for any additional troubleshooting. Contact our customer service (Monday-Friday 8AM-5PM Pacific Time) at either 800-626-0866 or info@territorialseed.com
My wife loves radishes so I grew these last fall - she was delighted and enjoyed the mildly spicy flavor

Raphanus sativus Radishes are best sown in spring or late summer, maturing when days are shorter, sunlight weaker, and temperatures milder; though some varieties are better able to handle summer conditions. The mildly spicy roots, low in calories and rich in fiber and cancer-fighting antioxidants, have good qualities as a digestive tonic or to clear the sinuses and ease sore throats. Anti-microbial properties made them a detoxifier in traditional medicine, and couple with high vitamin C for an immune boost. Don't discard the tops, as they are even denser with nutrients.
Days to maturity are calculated from date of direct seeding.
Culture
• Prepare the bed by working compost into the top 2-3 inches of soil
• Needs consistent soil moisture due to shallow root systems
• Dry or crowded conditions will slow growth and make roots hot or pithy
• The season may be extended from February through October by sowing in cold frames or using row covers
• For extended harvests plant every two weeks
Direct Sowing
• Direct sow spring through early summer
• Three grams will sow 7-8 row feet
• It is essential to thin promptly when they form 2 true leaves
• Sow mid-August—mid-September for a fall crop
Insects & Diseases
• Common insects: See Brassica Insect Information below
• Disease prevention: 5-7 year crop rotation
Harvest & Storage
• Harvest while still young (before splitting)
• Remove tops before storing
• Let a few plants bolt and make a seed pod — green pods have a crunchy, mild radish flavor
• Store at 36°F and 100% relative humidity
What is seed tape?
Seed tapes are perfectly straight rows of precisely spaced crops. No more having to thin seedlings! This biodegradable tape will plant a row 5 meters (16 feet, 5 inches) long. Simply lay it in a furrow and cover with a light layer of sifted compost or soil, water and wait. Save yourself a heap of planting time with these popular vegetable and herb staples.
Brassica Insect Information
Aphids: Control aphids with ladybugs or a hard spray of water or Pyrethrin. Also, select varieties that mature later in the season when aphid populations decline.
Cabbage worms, loopers, and root maggots: The first sign of cabbage worms will be off-white butterflies fluttering near the plants. They lay their yellowish-colored eggs on the undersides of leaves, which hatch into caterpillars that can cause severe root and head damage. To control light infestations, spray plants with Bacillus thuringiensis (B.t.). For heavy infestations, bait cabbage worms by mixing wheat bran into a B.t. solution. Add 1 tablespoon of molasses. Broadcast the bran mixture around the base of plants. Reapply as necessary. Using Reemay or Summer Insect Barrier can also provide control.
Flea beetles: Flea beetles chew tiny pinholes in leaves. Early control is essential to minimize the damage. Spray infected plants with Pyrethrin. Using floating row covers such as Summer Insect Barrier can also provide control.
Symphylans: In some areas of the US, symphylans (also known as garden centipede) can severely impede the plant growth of many crops. Only 1/4 inch long, white, and very active, they eat the root hairs of developing plants. Using larger transplants helps reduce damage. Contact your local county extension agent if you suspect you have a problem.
