Roxanne Hybrid Radish Seeds

27 days from direct-sowing.

To quote the song, Roxanne has really "put on the red dress" when it comes to this award-winning radish! Perfectly round, crisp globes up to 1½ inches in diameter grow in just about any climate and finish in under a month. And even if they don't get harvested promptly or receive a bit too much heat and sun, they refuse to sacrifice their flavor, texture, or color!

Roxanne won a 2015 All-America Selection for its garden performance, so you know that gardeners across the country, in a wide range of climates and conditions, have grown it successfully. The AAS judges noted that this radish stayed firm and solid even when it grew oversized, and that it had no "bleeding" (loss of bright red outer color), streaking (red streaks in the white flesh), or pithiness (mealy texture) even when held for a long time past its harvest. This means less waste and worry for you!

This spicy, flavorful radish has pure white flesh, a crispy crunchy bite, and a diameter of between 1 and 1½ inches on plants with about 8 to 10 inches of aboveground growth. In the garden, the plants should be spaced about 6 inches apart. But Roxanne is also compact enough to grow in any container with a depth of about 4 inches or greater! Fun kitchen windowsill project!

Radishes are a cool-season crop, thriving in spring, fall, and in mild climates, even winter. They are the quickest to finish of all the garden veggies, making them a good choice for children's gardens.

Roxanne is easy to grow and quick to harvest. Before planting, fertilize the soil and make sure that it is as loose, moist, and rich as possible, since the root needs space to develop and has little time to push its way through heavy soils. If you're planting to successively sow radish seed all season (recommended for a steady diet of delicious eating!), fertilize the soil again about 2 weeks after planting. Direct-sow successively every week from earliest spring until late spring or early summer, then again in late summer and fall for autumn and early-winter crops. Pkt is 200 seeds.

Root crops are popular with both commercial growers and home gardeners because they're versatile, delicious, and in many cases, perfect for canning or over-winter storage. Beets, Radishes, Turnips, and Carrots contain numerous vitamins and nutrients, offer a wide range of flavors and textures, can be enjoyed raw or cooked, and are wonderfully easy to grow!

Choosing a Variety

When choosing which Beets or Radishes to grow there are several factors you will want to take into consideration. First of all, both come in a variety of interesting shapes and beautiful colors, so pick whatever appeals to your eye! Also, Radishes offer varying degrees of heat and Beets have flavors that range from earthy to sweet. Smaller Beets are usually the best for canning and pickling, and many people enjoy the nutritious Beet greens as well as the root itself. As far as choosing a type of Carrot to plant, you will be deciding mostly by color and shape.

When to Start

Direct sow your root crops in early spring or late summer. They're cool-weather crops, most preferring temperatures of around 70 degrees F in order to germinate. All but Carrots will germinate in a week to ten days. Carrots can take up to 3 weeks.

How to Start

Direct sowing is preferable to transplanting because there is less root disturbance. Before sowing, cultivate deeply.

Beets: Soak the seeds in warm water for 24 hours before sowing -- this will aid in germination. Early spring is the typical time to sow your Beets, but in zones 9 to 10 you can sow outdoors in the fall. Sow at a depth of 4 times the size of the seeds, planting successively at 3-week intervals for crops throughout the season. Site in full sun in a loose, rich, well-drained soil. Expect germination in 10 to 15 days and harvests within 50 to 60.

Radishes: Early spring is the typical time to sow your Radishes, but in zones 8 and warmer you can sow outdoors in the fall for a winter crop. Sow at a depth of 4 times the size of the seeds, planting successively at 2-week intervals until mid-spring and then again in late summer. Site in full sun in a loose, rich, sandy, moist, well-drained soil. Expect germination in 6 to 10 days.

Carrots: Early spring is the typical time to sow your Carrots, but in warm climates you can sow outdoors in the fall for a fall crop. Sow at a ¼-inch depth, planting successively at 3-week intervals until early summer. Site in full sun in rich, loose, deeply worked and well-drained soil. Expect germination in 14 to 21 days.

Turnips: Sow in early spring after all danger of frost is past but while the ground is still cool. You can make successive sowings up to 5 weeks before temperatures are above 80 degrees F, then again in late summer if you want a fall harvest. In zones 8 and warmer you can also sow from early fall through spring for continuous crops over the winter. Sow at a depth of 4 times the size of the seeds. Site in full sun in fertile, moist, well-drained soil. Expect germination in 8 to 10 days.

Special Considerations

• Apply mulch or soil around the tops of the roots to eliminate green shoulders.
  
• Thinning out seedlings is particularly important when dealing with Beets, as each Beet“seed ”is actually a fruit that harbors several seeds. Remove the smaller, weaker seedlings and allow the stronger ones to grow. The ones that have been removed can then be used as greens.
  
• Crowding and insufficient water can cause Radishes to bolt or fail to form a bulb.
  
• Carrots -- Young seedlings are weak and slow growing, so if a heavy rain occurs after your seeds have been sown and the surface of the soil becomes packed, you may not have any seedlings emerge.
  
• Keeping weeds under control is especially important during the first few weeks after planting. Be careful to only do shallow cultivation, however, as digging too deeply can injure tender roots.

Growing Tips

• Most root crops prefer loose soils and cool temperatures.

Beets:

• Fertilize prior to planting your Beets and again when the plants are 3 to 4 inches tall. Keep the plants well watered.
• You can harvest your Beets at any time during their growth cycle, but they are typically most tender after 40 to 50 days, when they're between 1½ to 2 inches in diameter. The greens are best if picked when they're about 4 to 6 inches tall.
• Leave at least an inch of foliage on the Beet root when you harvest. This will prevent bleeding during cooking.
• Beet roots and greens will keep in your garden for 2 to 3 weeks after they have matured, and once harvested, the roots will keep for up to a month (store near freezing, with high humidity to prevent wilting).

Radishes:

• Use a liquid fertilizer prior to planting your Radishes and then again every 2 weeks. Keep the plants well watered.
• Radish leaves can also be harvested. They're best when young, about ½ to 1½ inches across. You can cook them or add them fresh to a mixed salad.

Turnips:

• Fertilize prior to sowing your Turnips and again when the plants are about 4 inches tall.
• Turnip greens are also quite popular and are best harvested when young and tender. The roots themselves should be harvested when they're about 2 inches across.

Carrots:

• Carrots are typically sown using two different methods. The first is to plant in single-file rows. The other way is to scatter the seeds in areas up to 12 inches wide. Both methods work quite well, but the second one provides higher yields.
• Since Carrots are slow to germinate (keep soil moist throughout germination), you can mix faster-germinating veggies such as Radishes or Lettuce with the Carrot seeds. This not only marks the area for watering and weeding but these other seeds can help break up any crusting on the soil surface, making growth easier for your Carrots. You'll harvest these other veggies before they have a chance to crowd the Carrots.
• Apply a 1- to 3-inch layer of dried grass clippings, well-rotted compost, or other organic mulch around the base of your Carrots once they've emerged and are growing well. This will conserve moisture, regulate soil temperatures, reduce weeds, and help prevent the tops of the roots from turning green or purple. These discolored areas will have a slightly bitter taste.
• Carrots are harvested from baby size to full grown, and their leafy tops are used to flavor soups and other dishes.
• Foliage growth in Carrots can be misleading, so don't use that as an indication of root size. Loosen the soil around the top of the carrot, and if the roots are finger-sized or larger, they're ready to eat.
• Store your Carrots at 32 to 40 degrees F, or in fall and winter, just leave them in the garden until you want them.

Pests and Problems to Watch For

• The most common problem people face when growing root crops is failing to thin the plants properly. Sufficient space is essential for healthy crops.
  
• Root maggots can tunnel into Radishes. If this has been a problem in the past, apply an appropriate soil insecticide before planting.
  
• A lot of moisture after a dry spell can cause mature roots to burst and split. Try to maintain an even level of moisture.
  
• Carrots -- Forking (forked or deformed roots) can result from stones, deep and close cultivation, planting in a soil that's poorly prepared, or the attack of root-knot nematodes. These parasites exist in the soil in areas with hot climates or short winters. They infect the roots and create root-knot galls that drain the plant's nutrients. Young plants that are infected may die, while mature plants usually have a decreased yield. There are several means of control, including crop rotation and treatment of the soil with appropriate pesticides. Contact your County Extension office for removal or prevention methods.
  
• Carrots -- Seeding too thickly and not thinning the seedlings adequately will result in twisting and intertwining of the roots.

Radish Germination Information

• Best sown outdoors in situ when the soil is cool
• It is a cool season crop that should be successively sown every 2 weeks until mid-spring and resumed again in late summer
• In Zones 8 and warmer, seeds can be sown in the fall for a winter crop
• Seeds can also be sown indoors at a temperature of 68-70°
• Indoors and out, sow at a depth of 4 times the size of the seeds and expect germination in 6-10 days

This annual is grown mainly for its enlarged, crisp-tasting, edible root, but the leaves can also be consumed. The plant is a rosette of leafy greens that grows 6-8 inches tall. The leaves are best when harvested young; cook them or add raw to a mixed salad. The roots are rounded or elongated, the flesh is white, and the skins can be white, red, pink, or bicolored. They should be harvested when 1/2- 11/2 inches diameter and before they become tough and woody. They are at their spiciest when dug in hot weather or just before they go to seed

The Park Seed Gold Standard

Heirloom Seeds are open-pollinated -- they are not hybrids. You can gather and save heirloom seed from year to year and they will grow true to type every year, so they can be passed down through generations. To be considered an heirloom, a variety would have to be at least from the 1940's and 3 generations old (many varieties are much older -- some 100 years or more!).

Hybrid seed are the product of cross-pollination between 2 different parent plants, resulting in a new plant/seed that is different from the parents. Unlike Heirloom seed, hybrid seed need to be re-purchased new every year (and not saved). They usually will not grow true to type if you save them, but will revert to one of the parents they were crossed with and most likely look/taste different in some way.
