Radishes can tolerate frost, so sow directly outdoors 4-6 weeks before the last spring frost date; or in late summer for a fall harvest. Plant seeds 1/4 inch deep in a sunny spot, without shade, in rich, well tilled soil. If soil is clay-like mix in some sand and fertilizer. Distribute seeds evenly about 1 inch apart in rows 6-12 inches apart. Thin radishes 1 every 2-3 inches when plants are a week old. Consistent, even moisture is key with radishes. Keep the soil moist with frequent, shallow waterings.
Radishes are Fast Growers: When you think they're ready to harvest, pull one out to test it. The bulbs should be about 3/4 to 1 inch in diameter.
Harvest All Season Long: Plant new seed rows every 10 days or so -- while the weather is still cool -- for a continuous harvest during the growing season.
Wit & Wisdom: Practice three-year crop rotation. In other words, only plant radishes in the same spot every third year. Read The Old Farmer's Almanac Radish Growing Guide!
Help Your Plants Thrive with Weed Control: Weeds compete with vegetables, flowers and other plants for water, space and nutrients. Give your plants their best life by keeping weeds under control with Organic Weed Barrier Paper, mulch or careful weeding.
Are Your Seeds Organic? What does Certified Organic and/or USDA Organic Mean?
All Purely Organic Seeds (and many varieties of the other seed brands we carry) are Certified Organic and carry the USDA Organic Seal. This means that our seeds are non-GMO (not genetically modified), and are chemical and pesticide free. They have passed rigorously standards and certified by a USDA Accredited agency. To determine whether the seed packet you're interested in is organic, look for the USDA Organic seal.
Are Your Seeds Heirloom? What are Heirloom Seeds?
Heirloom Seeds (sometimes called Heritage Seeds) are open pollinated vegetable and herb seed strains that have been planted, grown and harvested for several generations (usually more than 30 or 50 years depending on the variety) with consistent results. Heirloom seeds are always non-GMO and are never hybrids. All of our vegetable and herb seeds are heirloom seeds.
Are Your Seeds Non-GMO? What Does Non-GMO Mean?
Non-GMO means seeds (or other products) that were produced without genetic engineering and were not derived from GMOs (Genetically Modified Organisms). All of our seeds are non-GMO.
Where do Your Seeds Come From?
Most of the seeds offered on our site are USA Origin seeds sourced from certified US based suppliers. We do also source a small number of seeds from other countries. To view the specific origin of any of our current seed offerings, check the seed packet or look in the specifications for "Country of Origin" on any product page.
How Can I Store My Seeds Safely for Use in the Future?
Our seeds will generally retain their high germination rates for several years from the date of purchase. If you're planning on saving your seeds for us in the future, the most important thing to remember that seeds like to be stored where it is cool, dry and dark. The easiest way to ensure this for long term storage at home is to double-seal your seeds inside two zipper style bags and then place them in the freezer. (Make sure you label your seeds for future reference if they're not in original packaging.) When you're ready to plant your seeds, take just the ones you want to use out of the freezer and let them sit on a counter, in a covered container, for a few days to thaw and stabilize before being planted. To preserve germination rates, minimize temperature, light and humidity fluctuations by storing your seeds at the back of the freezer and only taking them out when you're ready to use them.
The Package with my Seeds in was Left Outside in Freezing and/or Rainy Weather. Will the Seeds Still Work?
As long as your seeds have not gotten wet they should work fine. Freezing temperatures will not hurt the seeds.
