All Seasons White Daikon is a versatile root vegetable prized for its crisp texture and mild flavor. Gardeners grow this variety year-round in many climates because it tolerates cooler temperatures better than standard radishes, making it ideal for spring and fall harvests.
Starting All Seasons White Daikon: indoors or direct sow?
🌾 Sow directly in the garden — All Seasons White Daikon is not usually started indoors.
This variety is best direct-sown in the garden rather than started indoors and transplanted.
Soil, care & harvest
Prepare your soil to a pH between 6.0 and 7.0 with good drainage before sowing. As a cool-season crop, you should direct sow seeds 2 to 6 weeks before the last frost date. Press seeds gently into the soil at a depth of about one inch, as they typically germinate within 5 to 10 days.
Space plants 4 to 6 inches apart to allow roots room to expand without becoming woody. Provide deep, consistent watering totaling 1 to 1.5 inches per week to prevent cracking and ensure steady growth. Apply a light layer of mulch around the base to retain moisture and suppress weeds, but keep it away from the crown.
Watch for flea beetles, cabbage root maggots, and aphids; use row covers or insecticidal soap if infestations occur. Prevent clubroot and black rot by rotating crops and avoiding waterlogged soil. Harvest roots when they reach full size after 60 to 70 days from sowing, pulling them carefully before the ground freezes.
