Growth Stages
Germination & Seedling
7-10 daysSeeds sprout in 3-5 days; cotyledons emerge followed by first true leaves. Young plants develop a small rosette of deeply lobed foliage.
Keep soil consistently moist. Thin seedlings to proper spacing once they have 2-3 true leaves. Remove thinned seedlings carefully to avoid disturbing roots of remaining plants.
Vegetative Growth
20-30 daysPlant develops deep green, feathery compound leaves on long petioles. Root begins elongating beneath soil surface.
Maintain consistent watering. Monitor for leaf damage from pests. Weed regularly but carefully to avoid root disturbance. Side-dress with compost if growth slows.
Root Development & Sizing
15-25 daysLeaves continue expanding; underground the root lengthens and thickens, becoming the characteristic long white daikon. Plant appears bushy and vigorous.
Continue consistent watering—critical stage for quality roots. Prevent bolting by maintaining cool temperatures and adequate moisture. Begin light cultivation if soil has crusted.
Maturation & Harvest Readiness
5-10 daysRoot reaches full length (12-18 inches) with white skin visible at soil surface showing slight shoulder above ground. Leaves may show some yellowing or weathering.
Check root size by gently uncovering the shoulder; harvest when roots feel firm and reach desired size. Avoid overwatering as this causes splitting.
Storage/Post-Harvest
Variable (storage phase)Harvested roots maintain crisp texture and mild flavor when properly stored. Flesh remains white and translucent.
Remove tops immediately after harvest to prevent moisture loss. Store at 32-40°F in high humidity; daikon keeps 2-3 months in cold storage. Can be left in ground in cool climates for extended harvest.
Common Pests
-
Use row covers early; spray neem oil or insecticidal soap; dust with diatomaceous earth; plant radishes early spring/fall when populations are lower
-
Use row covers to exclude flies; practice crop rotation; apply beneficial nematodes to soil; use yellow sticky traps
-
Spray with strong water stream; use neem oil or insecticidal soap; encourage beneficial insects like ladybugs; row covers for young plants
-
Avoid brassicas in same location for 4+ years; maintain soil pH above 6.8; remove infected plants immediately; choose resistant varieties
-
Use disease-free seed; avoid overhead watering; remove infected leaves; practice crop rotation; ensure good air circulation

Harvest Tips
Harvest when roots are 10-18 inches long, typically 50-70 days from sowing. Check by gently uncovering the shoulder; roots should feel firm and crisp. Harvest in morning for best crispness. Pull gently by grasping crown of leaves and twisting slightly; use a garden fork if soil is compacted. Remove green tops immediately to prevent moisture loss. In mild climates, daikon can be left in ground and harvested as needed. For storage, brush off soil and remove all foliage; store at 32-40°F with high humidity.
Fun Facts
