Radishes are the fastest growing vegetable in the garden. They are direct seeded and germinate very quickly. You will need to thin so plants are 1 inch apart.

They mature in approximately 30 days and do not last long once they mature so harvest them quickly. Succession planting every few weeks lets you harvest all season.

This plant will do well in a container, just make sure they are watered well, do not let them dry out.
