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.	Until it sprouts, place it in a shady place for half a day. Avoid direct sunlight; place in a semi-shaded area (with diffused light).

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 roots After 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.
