Radishes are easy to germinate from seed and can be sown direct in the ground. For more information see this guide to Growing Radishes.

How to collect radish seeds from plants in the home garden.
- Choose the Radish then Let Flower
Let the radish flower then continue to water regularly and fertilize every two weeks with liquid fertilizer.
- Pick the Drying Seed Pods
After flowering the seed pods will form along the flower stems. As the seed pods dry out pick off the dried pods then place in an open container.
- Leave to Dry
Once all the pods have been picked leave in the open container in an area with good air circulation for a week or two to finish drying.
- Dislodge the Seeds
Holding each pod above a bowl, crack the pod open between your fingers then dislodge the seeds. There will be anywhere between 1 to 6 seeds in a pod.
- Discard the Pods
Place the seeds in the bowl then discard the pods. They can be added to your compost.
- Store the Radish Seeds
Place the radish seeds in an airtight container or bag then label with the contents and the date collected. Store in a cool, dark and dry place.
Radish seeds will be viable for up to 2 years with the germination rate going down after that time.
