Daikon: The Juicy Giant from the East

Daikon (Japanese radish) is a true giant among root vegetables. Some varieties can reach up to 60 cm in length! Unlike black radish, daikon contains no mustard oils, so its flavor is very mild and juicy. It's the perfect vegetable for those watching their weight and digestive health.

Soil: Where Does Daikon Find Space to Grow?

Since the daikon root is very long, deep and light soil is vital for its success.

• Best Choice: Light Sandy soils (Type 2) or very loose Loamy soils (Type 1).
• Soil Check: Perform the sausage test. If the soil crumbles and holds no shape (Type 2), it's ideal: the daikon can grow deep without obstacles, remaining straight.

Best Companions (Good)

• Onions: Help repel flea beetles.
• Lettuce: Does not compete for soil depth.
• Nasturtium: Acts as a decorative and functional pest deterrent. See our nasturtium trap crop guide.

Main Enemies (Bad)

• Walnut Trees: Traditional danger. In the walnut's toxic zone, daikon grows crooked and tough. Check the walnut tree toxic radius for safe planning.
• Stony Soil: Any obstacle in the ground will cause the root to fork and twist.
• Heat: At temperatures above 25°C, daikon often stops growing and starts bolting.

AgroPlanner Tip: Daikon is best sown in the second half of summer. In our app, it occupies a 1x1 grid, but consider the soil cultivation depth! The system will suggest the optimal spot and flag the walnut toxic zone in red.
