How to grow radishes on a balcony 

I can’t mention often enough how happy I am about our new appartement and that we finally have a balcony. This little “third room” as I like to call it makes our home feel way bigger. I already tend to spend most of my free time on it. Mostly taking care of my balcony garden which I planted for the first time ever this year. We’re growing so many vegetables and only one sort of fruit: strawberries. We have basically a container garden on our balcony. My first successful harvest are my radishes. So I want to share on how I turned tiny little seeds into this wonderful organic produce. It’s super easy and fun! And let me tell you those radishes taste amazing! You can also turn the green part into a pesto or salad. And since it’s homegrown you know exactly that there are no pesticides of any kind used.

Radishes grow super fast and are a great gardening beginner projects for kids and adults like me. Let me share with you how to grow radishes in a container.

Growing radishes in a container

You’ll need:​

  • Container/Planter
  • Radish seeds
  • Soil (starter soil and regular soil)
  • Watering can

Alright! Let’s get started. You can plant radishes in containers all through spring and summer up until autumn. I started planting them indoors in March. If you want to pre-grow radishes indoors you’ll have to use special starter soil to promote root grow. After the last frost you can plant them outside even directly into regular soil in a container. Just make sure it drains well. The seeds will  germinate in less than 5 days.
If you grow seedlings inside you have to carefully transplant them into the outdoor container. The soil needs to be enriched with manure or organic fertilizer to promote strong radishes. The container should be at least six inches deep but can vary in size as radishes are a small root vegetable and don`t need that much space.

I grow different kind of radishes the ones pictured a a red kind with white tips. I also grow yellow, purple and white ones which all need the same conditions.

Indoors and outdoors you’ll have to plant the radish seeds individually up to one inch deep and one inch apart. Cover them lightly with soil.


Radishes like direct sunlight for up to six hours and will need a lot of water. Make sure to water them daily. I water mine once in the morning and once in the evening. The container should have a hole at the bottom so excess water can get out.  Never water during the day as water drops and sunlight can burn your plants. Radishes will need somewhere between 4-6 weeks to fully grow. Once you can see the red bulb peeking out of the soil you can just cover it again so the bulb won’t dry out. It’s kind of difficult to find the right time to harvest. If you wait too long the vegetable will get woodsy and won’t taste as good.
