Both cucumbers and radishes are annual plants, which means they will only last for one growing season. Therefore, in order to have a continuous supply of these vegetables, you will need to plant new seeds every year.

Fortunately, cucumber and radish seeds can be saved from the previous year’s crop to plant the following year. Then, simply allow the fruits to mature on the vine until they turn yellow or brown.

Cut them open and remove the seeds, then dry them in a cool, dark place before storing them in an airtight container.

When saving radish seeds, selecting the largest and healthiest roots from your crop is best. Allow them to mature for at least 2-3 weeks after harvest before removing the seeds.
