Description

(Brassica rapa). A Japanese salad turnip with gorgeous, golden skin and oh-so-sweet flesh. It is excellent raw or cooked and exceptionally easy to grow. If you love the Hakurei turnip, you are sure to love this tender, gilded little morsel. This thin-skinned salad type is scrumptious raw, or can be roasted, steamed, and added to soups.

Growing Tips: The Aji Kogane turnip thrives in well-drained, fertile soil rich in organic matter. It prefers full sun but can tolerate light shade. Keep the soil consistently moist, especially during dry periods, to ensure tender roots and prevent them from becoming woody. Regular weeding and mulching can help maintain soil moisture and prevent competition from weeds. Companion planting with radishes can help deter pests.

When to Grow

Aji Kogane is a cool-season crop, best planted in early spring or late summer. It grows well in USDA zones 3-9. For spring planting, sow seeds as soon as the soil can be worked, about 2-3 weeks before the last frost. For a fall harvest, sow seeds 6-8 weeks before the first expected frost. If you’re not sure how to find your area's first and last frost dates, consult our blog post 'Our Experts Answer Questions, Share Resources.'

How to Sow and Plant

Sow seeds directly in the garden, about 1/4 inch deep, and 1-2 inches apart. Thin seedlings to 5 inches apart to allow ample space for root development. Rows should be spaced 12-18 inches apart. This spacing helps to ensure that the roots can develop properly without overcrowding.

How to Grow

Fertilize with a balanced, all-purpose fertilizer at planting and again midway through the growing season. Ensure the plants receive at least 1 inch of water per week. Mulching helps to retain moisture and keep the soil cool. Harvest turnips when they reach 2-3 inches in diameter for the best flavor and texture.

How to Save Seeds

To save seeds, allow the plants to flower and set seed. Once the seed pods have dried, harvest and store the seeds in a cool, dry place. Ensure that no other Brassica species are flowering nearby to prevent cross-pollination.
