How To Grow Radishes - Homemade Mastery

Radishes are probably one of the easiest-to-grow vegetables out there! They were one of the first things I was super successful with on my gardening journey and they gave me so much confidence to continue to grow my own vegetables. So, today I want to share with you how to grow radishes from seeds – it’s really easy and can be very encouraging for beginners too!

As members of the Brassicaceae family, radishes are close relatives of broccoli, arugula, cauliflower, kale, cabbage as well as collard. The members of this plant family are shown to have potent anticancer and anti-inflammatory properties mainly due to the isothiocyanates found in them (source).

Although they are better known for their crisp, colorful, and peppery roots, the greens are also edible. I actually have a refreshing salad with radishes and their greens right here.

These crunchy root vegetables mature so quickly that it is possible to plant them several times a year. Best time to start them in my opinion is September and probably March.

In fact, the whole process from sowing to harvesting usually takes around 30-40 days. So, if you feel like you need the fruits of your labor quickly, then put on your gardening gloves and make some space in your backyard, because we’ll learn how to grow radishes from seeds.

General Tips For Growing Radishes

These vegetables like sunlight, but enjoy cool weather – so summer isn’t their favorite season.
Radishes like moisture, so make sure you water them regularly. I actually made the mistake of planting some during summer, when there’s not enough moisture (even when you water daily) and they turned out bitter, dry and very very spicy. There’s a time for everything, right?
Radishes like well-draining soil. So if yours is compacted, you can mix in some potting mix or compost or even sand to loosen it up. As a result, the drainage will improve, too.
If you want to have more regular supply of radishes you can keep sowing new seeds every 3-4 weeks. This way you will have a new batch of radishes once you’ve gone through one.

How To Grow Radishes directly in The Garden

The best time to start growing radishes in my opinion is 4-5 weeks before the last expected spring frost. So in my area, that’s around end of January to mid February.

In case you aim for a fall crop, then the best time to sow radishes is after summer, when the weather starts getting a bit cooler (September – October) – they don’t like heat.

Here’s how to do it:

Firstly, choose a suitable place for growing your radishes. Since they mature quickly, you can sow them wherever you have some space available in the garden. You can even sow them in between rows with other veggies. Just make sure that they receive at least 6 hours of sunlight during the day.
Then sow the seeds about 1/2 inch deep and 1 inch apart. Then cover them loosely with soil…
Water thoroughly and regularly to encourage the germination process (if the rain doesn’t show up to help you out).
Once the seedlings become as tall as 2 inches, thin them out to at least 3 inches of spacing. This way, they will have enough space to develop nice, plump roots.
Don’t throw away the seedlings because these baby greens make a great salad. But if you don’t want to make a salad right then and there and have some space, you can actually replant them by poking a hole for each radish wherever you have space. Cover with soil and water regularly throughout the next week. At first the replanting seedlings will look a bit rough, but trust me with time, those thin mini radishes will develop beautiful big red bulbs and will taste delicious.
In 30-40 days the radishes will be ready to harvest. Don’t leave them in the ground for too long because they will become tough.
The best time to pull them out is when the bulbs are about 1 inch in diameter while the greens are 6-8 inches tall.

how To Grow Radishes In Containers

If you are keen on gardening radishes but don’t have a garden, then you can easily grow them in pots. Here is how to do it:

Firstly, choose a container that is at least 6-8 inches deep and has a diameter of around 12 inches. Radishes have shallow roots, so a wide pot will be much more beneficial than a deep one. Make sure the pot has drainage holes at the bottom to prevent waterlogging.
Radishes come in different varieties, so pick one that suits your preferences and container size.
Use a high-quality potting mix for growing your radishes. Alternatively, you can prepare your own by combining equal parts of garden soil, compost as well as perlite for improved drainage.
Sprinkle the radish seeds evenly across the soil surface in the pot. Radish seeds are relatively small, so plant them about 1/2 inch deep. Aim for a spacing of about 1 inch between seeds.
The next step is to lightly cover the seeds with a thin layer of soil or compost, about 1/4 inch. Then water the seeds to encourage germination and maintain consistent moisture throughout the growing process.
Place the pot in a sunny spot where the radishes can receive at least 6 hours of sunlight throughout the day. As mentioned, radishes prefer cool temperatures, so they grow best in spring or fall when the weather is cool, yet mild.
Once the seedlings are 2 inches tall, thin them out to ensure adequate spacing for proper root development. Remove weaker seedlings, leaving about 2-3 inches of space between each plant.
If you have another container, you can fill it up with soil, poke a few holes for each one of the weaker seedlings. Again, leave 2-3 inches between the plants. They won’t look great in the beginning, but water regularly and they will stabilize and turn into bigger bulbs with time.
If your feel like your potting soil lacks nutrients, you can use a balanced liquid fertilizer once or twice during the growing season. Follow the instructions on the fertilizer package for application rates.
Radishes mature very quickly, usually within 3-4 weeks after sowing. Harvest them once they reach the size of around 1 inch in diameter by gently pulling them out of the soil. Alternatively, you can use a small garden trowel to lift them.

How To Use Radishes

And now that you know how to grow radishes and you have some, let’s see how to use them. Both greens and roots can be healthy ingredients for your recipes.

Radish Greens

Radish greens are not only edible but also really healthy. Their flavor can vary from mild to slightly bitter or spicy, so, it would be a good idea to taste a small piece before using them. You can consume them both raw and cooked in a variety of ways:

add to salads, either on their own or mixed with other leafy greens.
sautéing radish greens is another quick and easy way to enjoy them. Just season with salt and pepper, as well as a splash of lemon juice and serve as a healthy side.
Radish greens are great for both stir-fries and curries just like any other leafy greens.

Radish Roots

Radishes bulbs are more often consumed raw in salads, but they can also be cooked in numerous tasty dishes. Here are some suggestions:

Radishes add a refreshing crunch to both green and mixed salads.
You could also pickle radishes so as to preserve them and add a tangy flavor.
Roasting radishes in the oven brings out their natural sweetness and mellows their spiciness. Roast for as long as 20-25 minutes until they become tender and slightly caramelized.
Radishes can also be cooked quickly in a sauté pan. Sautéed radishes work well either as a side dish or in stir-fries.
Make a slaw using radishes by either shredding or thinly slicing them.

Have fun gardening!
