If your radishes “bolted” (flowered) and took over your garden last year like mine did, don’t worry—you didn’t fail. You just accidentally grew a massive harvest of seeds! Radishes are one of the easiest vegetables to save seeds from, turning a forgotten harvest into a lifetime supply.

Step 1: Wait for the pods to turn brown
Don’t pick the pods while they are green and fleshy. For the seeds to be viable, the pods must dry completely on the plant. Wait until the stalks turn brown and the pods feel light, crispy, and “corky.” If they rattle when you shake them, they’re ready.
Step 2: Harvest
Since bolted radishes can become huge and unruly woody bushes, the easiest way to harvest is to cut the entire stalk and place it in a large bucket.
- To extract: Some people will crush the pods by hand or put them in a sack and stomp on them.
- Then winnow: These pro gardeners will then pour the mixture between two bowls in front of a light fan. The heavy seeds will drop, and the light pod husks (chaff) will blow away. This is called winnowing. I’ve seen videos of farmers using special machines for this.
I don’t have the space in my apartment or patience to clean up the mess that this makes, so what I did with my haul is put on my favourite show and spend a few hours every weekend using my fingers to split the pods open, and then transfer my seeds to a mason jar. Which brings us to the final step.

Step 3: Storage
Radish seeds are tough and can stay viable for more than five years. Ensure they are bone dry, then store them in a labeled envelope or glass jar in a cool, dark place.
Why the Great Radish Takeover was worth It
Even though they crowded my garden, those radish flowers were a feast for pollinators, and their deep roots helped to aerate my soil. So I’ve traded a few salads for hundreds of future plants! If anyone wants any radish seeds, I have a nice seed supply to exchange and share.
