Radish Seed Pods

The seeds are small and round, they look like little pebbles. They have a light brown color. The pods are very hard to crack open, but once opened, the seeds inside will pop out easily. You may notice that some of them are cracked open while others remain intact. Some of these seeds contain white or yellow colored kernels with black spots on top and bottom.

These kernels can be eaten raw or cooked into soup or porridge. The seeds are not harmful if eaten raw, but cooking destroys most of their nutritional value.

Daikon Seeds

These seeds are green and oval shaped. They have a dark red color and a slight taste of vinegar. Daikon seeds can be used in salads, soups, stews or even pancakes. Cooking destroys most of their nutritional value so it is best to keep them whole when eating them raw.

How To Collect Radish Seeds?

Collecting radish seeds is easy. You just need to go around planting radishes in your garden. Once planted, you can harvest the seeds from the plants after a few days. If you want to save time, then you can plant them right away and wait until they sprout before harvesting them. When they grow up into big plants, it would take about two years for them to produce enough seeds for harvesting. If you want to collect more radish seeds, then you can always plant them after harvesting.

How do you harvest them?

You can gather seeds from the pods after they’ve dried up and turn brown. If you have some plants that haven’t been harvested yet, then you can easily open up the pods by hand. You can also wait until they dry up and break into smaller pieces when lightly tossed by the wind.

It is easy to collect vegetable seeds. You just need to allow time for them to grow before they could be harvested. You can always gather the seeds of your own plants, and then use them for the next planting season. Gathered vegetable seeds should be properly stored for future use. You can find them in most seed and nursery shops.

Can You Eat Bolted Radishes?

Bolted radishes are edible, but most people do not consume them due to their bitter taste. They can be eaten raw or cooked. The leaves and the stems of the ray can be consumed as well if they are young and have not turned yellow yet. They should be treated in the same manner as spinach. They contain a lot of vitamin C, potassium and magnesium.

How to Prevent Bolting?

Bolting can be prevented by changing the soil of your garden. During the winter season, add lots of manure and some wood ash into the soil. This will provide enough nutrients for the plants during the growing period. If you do not want to use manure or wood ash, then you can use bone meal instead. It should be used during the middle of winter or early spring.

If you do not want to use chemical fertilizer, then you can scatter some grass clippings around your garden. This will provide enough nutrition for the plants without causing any harm to them. Some gardeners would add some hay over their garden, but this might cause fungal growth if it rains frequently in the area.

You can also plant radishes in a container that has good drainage. This can be achieved by placing some small stones at the bottom. Fill it with soil that does not contain too much manure or other nutrients. You should also poke some holes around the pot to allow air to circulate. This will prevent the growth of bacteria which causes bolting.

You can also prevent bolting by planting quick growing radish varieties such as ‘wildwater’, ‘cherry belle’ and ‘sugar plum’. They grow fast enough to produce edible roots before they have the chance to bolt.

How to Plant?

You can grow radish throughout the year. Just prepare your garden by plowing, tilling and raking it. Add some fertilizer before planting the seeds. You can also grow them in pots or containers that can be placed indoors. Make sure that they have enough light to promote good growth.

Sow the seeds about ½ an inch deep. You can put 2 to 3 seeds per location. Most likely, only one seed will grow anyways. Make sure that you keep the seed bed moist to help them grow faster.

Plant them in your garden once all danger of frost has past. The soil temperature should also be at least 60 degrees Fahrenheit. Otherwise, the seed may not germinate.

How to Grow?

You can weed the garden regularly. Weeds tend to compete with the growing radish seeds for necessary nutrients. Remove the weeds before they have a chance to spread out and strangle your plants.

You can also mulch the garden with some grass clippings or straw to keep the weeds from growing and to conserve moisture. Add some nitrogen based fertilizer to promote faster and healthier root growth.

You can start harvesting your radishes once the plants are about 6 to 8 inches tall. You can start removing the largest roots first, making sure to leave at least one leaf to allow smaller roots to grow.

You can leave the plants in the ground over winter and harvest them as needed. They tend to keep longer when they are left in the ground. Just leave some in the ground and replant some each spring.

You can also start harvesting the roots as soon as they are big enough to suit your purpose. Just keep checking on them every few days to see if they are ready.


You can store your radishes in many different ways. You can leave them in the ground and cover them with some mulch. This will prevent the roots from freezing and they will last until the following spring.

You can keep them indoors in moist sand or sawdust. Make sure that they do not have direct contact with the soil. You can also replant them in small pots and keep them in a dark area until you need them.

You can store them in perforated plastic bags or containers along with shredded newspaper. Keep them in a cool place such as a basement and make sure that they do not get too wet. Do not stack them as this can cause them to rot.


Planting quick growing radishes will prevent the plants from bolting. Just be sure to plant them as soon as you can so that they have enough time to grow and develop roots.

Always make sure to keep the leaves free of disease and not crowded. Space the plants out so that they have plenty of room for growth.

You can harvest your radishes at any size. The smaller ones will be hotter while the larger ones tend to be milder in flavor. Just pull them out of the ground with your hands or use a garden fork and gently loosen the soil around the roots before pulling. You can also use a knife or shovel to cut them out if they are stubborn about coming out.


Remember to always leave some in the ground for the following year!
