Radishes should be planted in an area with full sun or partial shade, and loose, well-drained soil. Remove any rocks from the soil, as the roots will bifurcate around any rocks in their way. Add organic matter to the soil before planting, such as compost, manure, or leaf mold.
Radishes are a cool weather crop best planted in spring and autumn. Growing radishes during the hot summer months may cause them to bolt. You can plant your first crop a full 2 weeks before the last frost in spring, as radishes endure frost well.
Because radishes grow so quickly, you can “inter-crop” them between slow-growing vegetables to make row markers. You can also “succession plant” them by sowing a new row each week, to spread your harvest over a longer period.
You will want them to be about 1/4 inch deep and 1 inch apart. As they germinate, thin the successful seedlings to about 2 inches apart, allowing more space for bigger varieties. Rows should be planted about 1 foot apart.
Keep the radish beds moist, but not soaked. Watering radishes frequently and evenly will result in quick growth; if radishes grow too slowly, they will develop a hot, woody taste. Add compost to the radish bed as desired to help retain moisture.Radishes are typically ready to harvest when their roots are about 1 inch in diameter. Check your seed packet for your variety’s expected size at harvest and time to maturity. To harvest, lift the entire plant out of the ground with your hand.
Radish, Raphanus sativus
Pollination, insect; Life Cycle, annual; Isolation Distance, ½ mile
An insect pollinated annual, radish can be a challenge to keep pure because in many areas there are an abundance of wild radish that will cross readily with your cultivated varieties. Being a small plant, they are easy to cage for isolation, and being fast maturing, time isolation is a great choice as well. Seed pods will form after the flowers die back, and you should allow the pods to dry on the plants for as long as possible before gathering. Pods are thick and do not shatter easily. Winnow to separate chaff.
Based in Asheville, NC, Sow True Seed has a small, dedicated staff of dirt worshippers committed to providing high quality, open-pollinated seeds in support of sustainable food production and regenerative agriculture. Founded in 2008 by lifelong gardener and food activist Carol Koury, Sow True Seed was created to preserve our shared botanical heritage and grow a new era of ecological wisdom.
Sow True Seed supports independent, regional agricultural initiatives that foster a vibrant, sustainable economy, and true food sovereignty. They are committed to growing our awareness and actions to honor the heritage of their seeds, the diverse people and places that have contributed to our collective abundance.
Based in the glorious mountains of Western North Carolina – home to a temperate rainforest and one of the most biologically diverse areas of North America – Sow True prides themselves on working with farmers in the region who ensure the survival of heirloom varieties that would otherwise become extinct.
The United States Department of Agriculture (USDA) requires that seed germination rates be tested at least once a year. A “sell by date” is also required on seed packets and cannot date more than a year from the last passing germination test. Sow True Seed tests the germination rates of all seed varieties twice a year via the North Carolina Department of Agriculture to ensure passing germination rates. The sell by date is not a “use by” date; most seed varieties, stored properly, can last up to three years. Sow True Seed stores all seed varieties in a climate controlled facility that averages 50° F and 50% humidity, which are ideal seed storing conditions. For the home gardener the best way to store seeds is in the refrigerator, in a zip top bag or Mason jar, with silica packets to absorb any moisture. We do not recommend storing seeds in the freezer.
