How to Grow Wakayama White Radishes
Direct seed this variety in a sunny location in the late summer or early fall. Soil should be loosened with a gardening fork or shovel and amended as needed; avoid high nitrogen fertilizers. Sow seeds 1/2" deep in rows 12 to 18 inches apart. Thin plants to 6 inches after germination. Keep soil consistently moist and treat diseases as needed.
Harvesting Wakayama White Radishes
Once your radishes have reached the desired size, harvest either by pulling the plants at the base or by digging them up. Large daikon varieties like this one often need to be dug up if your soil is fairly compacted. Remove the tops and store them in the refrigerator.
Daikon radish leaves are used for many dishes, so don’t throw them away! Wrap them in newspaper or plastic wrap so they stay fresh longer, store them in the fridge.
Daikon radishes are often used for oroshi in Japan. Oroshi is made by coarsely grating the radish with a special grater. It is used for sauces, garnishes, and much more! The leaves can also be used in stir-fries or soups. Try slicing your radishes and mixing them with a vinaigrette for a tasty side salad.
Tips From Our Gardeners
"Some daikon varieties, like this one, can be huge! I would recommend planting your radish rows in succession every week or two. You don’t want to be overwhelmed by a huge crop of foot-long radishes!"
- Katie Robinson, True Leaf Market Writer and Horticulture Student
Well-draining, fertile soil with a pH of approximately 5.8-6.8.
Pests and Disease:
Flea beetles, cabbage loopers, and root maggots all attack radish plants. These daikon radishes are no exception. Watch for signs of damage and treat as needed. Daikons are fairly disease-resistant if watered properly, but look for fungal diseases like damping off.
