I planted radishes this year, and it was a breeze from start to finish. So here is your guide to growing radishes in pots, super easy, super quick. Let’s start!

What Types of Radishes Can I Grow In Pots?

Like any other vegetable, there are many varieties to choose from to grow. Your options aren’t constricted to the round pink ones you find in the grocery store. Depending on what you fancy, you can choose to get radish slices for snacking or radish slabs for chopping and cooking. Here are the types that I recommend growing.

Most of the radishes that you’ll probably see in the grocery store are Cherry Belles. They’re perfect for chomping down on as a snack. You can also slice them up to replace chips and dip them in your favorite dips.

These are the variety that I grew this year, and let me tell you, don’t be fooled by their looks. These cherry belles pack a punch and are much tastier than the storebought kinds. I would recommend this variety to everyone.

If you’re a fan of cooking radishes with your dishes, try out the Japanese Daikon Radish. These radishes can be up to 16 inches long with their tubular shape.

These radishes are also great as a winter variety if you live in a chilly climate as I do. Make sure to grow this variety in a deep pot to get the most bang for your buck!

Now this radish is the odd one out of the bunch because people don’t grow it for the roots. People grow it for the edible seed pods from the greens of the radish.

You can use them like inground radishes and add them to stir-fries and stews. Apparently, the taste is a lot more subtle than inground radishes.

How to Start Radishes in Pots

Don’t start radishes indoors. That’s the first thing.

Radishes grow so fast that it would make starting them indoors obsolete. Not to mention that transferring them in any way would disturb the roots, even if you repotted them correctly.

Trust me, I made that same mistake and had to spend an hour carefully separating radish seedlings in 50-degree weather.

What’s better is to plant your radish seeds in a 6-inch deep pot that’s very wide. Radish roots fatten up as they grow and how big they grow severely depends on how much space you give it. Space out the seeds 2 inches apart and thin them so that there’s a plant every 2 inches or more. Or get a headstart and germinate them in paper towels.

When is The Best Time For Growing Radishes in Pots?

Radishes are what I call two-timers. You can grow them at 2 different times of the year. Spring and fall.

Officially, radishes are considered cool-season plants and are best grown during the spring and fall when it’s chilly. Other plants like radishes include broccoli, lettuce, swiss chard, and kale. Some varieties can tolerate a little bit of winter bite, like the Daikon!

If you were to grow radishes in the summer, the heat would cause them to bolt, or start to grow leaves and produce flowers. That is the exact opposite of what we want.

When growing radish in the spring, plant them 4-6 weeks before the last frost date. If you’re growing them in the fall, plant your radishes in pots 4-6 weeks before the first frost date. If you aren’t sure when your frost date is, or what they are at all, here’s a great guide on frost dates.

Replant a new batch of radish seeds every 2 weeks to get a continuous harvest.

What Do You Need For Growing Radishes in Pots?

It’s vital to pay attention to this section because the requirements for growing radishes can make or break your success. Especially with the sun!


Grow your radish during the cooler seasons. When it gets too hot, your radishes will bolt and become useless for eating. The roots will also remain as skinny tubes.


Just because radishes need cooler temperatures doesn’t mean that they need shade. Radishes need a nice sunny area, or they’ll put extra effort into growing leaves instead of the roots.


Water when the top inch is dry. Be careful about watering too much because that can cause root rot. And well, radishes are roots.


When growing radishes in pots, use good quality potting soil. Make sure that it’s well-draining to prevent root rot. Don’t grow your potted plants in garden soil or compost. Here’s why.


Radishes don’t need that much fertilizer. In fact, a huge problem with growing radishes in pots is having too much fertilizer in the first place, especially the macronutrient, nitrogen. Nitrogen can cause your radish to produce more leaves than roots and leave you with only a skinny radish to show.

How To Harvest and Store Radishes

You’ll know when radishes are ready 3 weeks after growth or when it’s 1 inch in diameter. If it’s not 1 inch in diameter, either it was too hot, or there wasn’t enough space. Still good to eat, however!

Don’t wait long after your radishes mature, or you’ll be eating a pitty, terribly-tasting radish. Like spicy dirt.

When your radish is mature, it’s as easy as pulling it out and washing it. Cut off the tops and the roots at the bottom and store them in a bag in the fridge. They last as long as they do when store-bought. Enjoy them as a snack, or add them to your dishes!

So What, Sarika?

So what is that it’s time to get some seeds and plant some radishes. Buy your seeds now so that when the seasons come around, you’ll have them ready to plant and enjoy. How about growing other cool-season plants along with radishes in pots?
