Growing Daikon Radishes: Tips for Giant Roots and Mild Flavor
Daikon radishes are long, crisp, white roots with a mild, sweet flavor, popular in Asian cuisine and winter gardens. They can grow over a foot long and thrive in cool weather. With the right care, you can harvest impressive roots perfect for fresh eating, pickling, or cooking.
Best Time to Plant Daikon Radishes
Plant daikon 6–8 weeks before your first fall frost or in early spring where summers are mild. They prefer soil temperatures between 50–65°F.
Soil Preparation
Daikon roots need loose, deep, and well-draining soil—free of rocks and hard clumps—to grow straight and large. Raised beds or tilled garden rows work well. Add compost before planting for steady nutrients.
Sowing and Spacing
Sow seeds ½ inch deep and space them 4–6 inches apart. For long, straight roots, avoid overcrowding and thin seedlings promptly.
Watering and Care
Keep soil evenly moist but not soggy. Dry periods can cause roots to become tough and pungent. Mulch to retain moisture and regulate soil temperature.
Harvesting
Harvest daikon when they reach full size—typically 50–70 days after planting—before the ground freezes. Loosen soil around the roots before pulling.
My Experience
I’ve grown daikon radishes for decades, often harvesting roots as long as my forearm. Loose soil, cool weather, and consistent watering have always produced the mildest, sweetest flavor.
