You do not use any harmful chemicals for radishes. Anyway, you also provide information make organic radishes for own use. Of course, your information is more important, because, How to plant, How to grow, how to use Chemical, Harvest in 3 weeks from planting.

  2. Hi Norman,

    Growing radishes look interesting. They start with seeds, right?

    We only have a short summer in Canada, we tend to plant tomatoes, beans and mustard only.

    Maybe, we will try radishes this summer if they take only 3 weeks to be harvested.

    Do you have a bountiful garden yourself?

    Thanks for the information.


    • Hello so nice to meet you radish can be stated with seeds or seedlings (young plant). Sorry to hair about the short summer you have. Maybe you can try growing them from containers using grow lights, that may help. I have a herb garden and a few flowering plants along with a lawn. My yard looks great after it is been nicely cut. Thanks so much for commenting, wishing you the best of success.
