White radish (Daikon radish)

The type of soil used varies depending on the product; please determine this based on the soil you have. Before placing the seeds, ensure the soil is moist. You can do this by using the following methods: |
 |
1 | Place the soil in a container and add waterPlace the potting soil into a flowerpot or container, slowly pour in water, and use chopsticks to thoroughly stir the soil to moisten it. |
 |
2 | Put the soil into a bag and add waterFill the bag with potting soil, then slowly pour in water until the soil is moist. |
Planting tips:
It is recommended to sow 1/3 of the seed quantity first (e.g., sow 3 out of 9 seeds) to maintain proper spacing. After the seedlings emerge, thin them out as needed, removing weak seedlings and keeping the strongest plants to provide more growing space.
Basic Planting Guidelines for White radish (Daikon radish)
Daikon radish is a cold-resistant, disease-resistant, and easy-to-cultivate variety. It has dense flesh and a refreshing flavor, making it suitable for pickles, cold dishes, and salads.
|
Ideal ambient temperature: around 20°C. |
Make sure the seeds are covered with soil. The depth shown in the diagram is approximately 1 cm . |
|
Avoid soil drying The soil must be kept moist. If it is too dry, the seeds will not be able to absorb water and will fail to germinate. |
Avoid direct sunlight; place in a semi-shaded area (with diffused light). |
Until it sprouts, place it in a shady place for half a day.Seed burying method
 |
Dig a small hole about 1 cm deep in the soil. Scatter about 3 seeds into the hole. Gently cover the seeds with soil around them, ensuring they are completely covered. Finally, gently press the soil from above to ensure it is in close contact with the seed. |
Post-germination management
For initial watering after germination and during the early growth stage, use a sprayer or similar tool to water gently, avoiding water flow that could wash away the seedlings. Water thoroughly only when the soil surface is dry.
 |
Thinning (shortening seedlings)Once the true leaves have emerged, leave only one seedling that is growing well and remove the others. |
 |
mound soil around the rootsAfter thinning the seedlings, to prevent the remaining seedlings from falling over, gather the surrounding soil around the base of the seedlings (mound soil around the base). |
 |
Lighting and ventilation management Choose a sunny and well-ventilated location for management. Sunlight is very important for plants. Ensure plants receive ample sunlight and maintain good ventilation to prevent disease. |
Harvest Time and Precautions <br>Harvest: The radishes can be harvested about one and a half months after sowing, when they sprout from the ground.
⚠️ Note:
If the harvest is delayed, the white radish may become hollow (with a hole in the middle) or bolt (tōritachi, which means flowering and seeding), resulting in a poorer taste.
Possible reasons why seeds fail to germinate
The ideal temperature for germination is 20°C. Please confirm that the sowing environment is maintained within the appropriate temperature range.
If the soil is too dry, the seeds will dry out, leading to a decrease in germination rate.
Excessive moisture in the soil can prevent seeds from breathing and even cause them to rot, thus affecting germination.
Seed aging or individual differences: If the seeds are too old or of poor quality, the germination rate will be reduced.
After germination and in the early stages of planting, water gently with a thin stream of water (such as a spray bottle) to avoid washing away the seedlings with a strong flow. Water thoroughly when the soil surface is dry.
Why didn't the seed sprout? Let us help you find out the reason.
Reason 1: Overwatering (root rot)
Reason 1: Overwatering (root rot)
Another reason is over-care and excessive daily watering.
If the soil is too wet, the roots cannot breathe and will rot and die. The roots will shrink and disappear, turn brown, and become thin and fragile.
Reason 2: Dryness
If you forget to water your plants, the soil will dry out and the plants will wither.
The leaves will become dry and brittle.
If there is still moisture in the leaves, water them thoroughly.
They might be able to recover.
Reason 3: Lack of sunlight (Extended)
If the seedlings do not receive enough sunlight after germination, the stems will grow too quickly and eventually break under the weight of the flower heads, causing the plant to wither. Make sure the plant receives ample sunlight and avoid overwatering.
Reason 4: The temperature is not suitable
Every plant has its optimal growth temperature.
Both excessively high and low temperatures can slow down plant growth and even cause plants to wither.
