Description

(Brassica rapa). Japan's legendary seedhouse Noguchi Seeds worked for decades to select and cross for a soft, salad-type turnip that would be superior in flavor and texture with crack resistance and rugged growth habit. Out of this effort came the Miyama turnip in the first half of the 20th century. It is widely considered the best of its class of turnips, and there is even an annual festival to celebrate this legendary local veggie. The Miyama stars in many fine Japanese dishes, from hot pots, salads, pickles, and soups to the delectable Senmaizuke, or thousand sheet pickle, where it is sliced impossibly thin and preserved with kelp and sweet vinegar. Market gardeners and foodies alike will love this highly gourmet, easy-to-grow and highly nutritious offering — and for those looking for a snackable veggie, this is a mild, raw eating turnip to serve with carrot sticks!

Growing Tips: Miyama turnips thrive in cool weather and are best grown in well-drained, loamy soil rich in organic matter. These turnips should be planted in full sun, although they can tolerate partial shade. It's essential to water them consistently, providing about 1 inch of water per week to prevent the roots from becoming woody or bitter. To protect young plants from pests like flea beetles, consider using row covers.

When to Grow

Miyama turnips are a cool-season crop and can be planted in early spring or late summer for a fall harvest. For spring planting, sow the seeds about 2-3 weeks before the last expected frost date in your area. For a fall harvest, plant them in late summer, around 70 days before the first fall frost. If you're growing them in a region with mild winters, you can even plant them in the fall and harvest throughout winter​.

How to Sow and Plant

Directly sow the seeds into the garden about 1/4 inch deep, spacing them 1 to 2 inches apart in rows 12 to 18 inches apart. Once the seedlings have a few true leaves, thin them to 5 inches apart to allow the roots to develop properly. The soil should be kept consistently moist until the seeds germinate, which typically happens within 7-10 days​.

How to Grow

After planting, keep the soil evenly moist but not waterlogged. Turnips grow best in cool temperatures, and their flavor improves after a light frost. Ensure that the soil remains loose and free of weeds to encourage healthy root development. As the plants mature, you can mulch around them to help maintain moisture and keep the roots cool​.

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.

FAQ

Can I grow Miyama turnips in containers?

Yes, Miyama turnips can be grown in containers. Choose a deep pot with adequate drainage, and use a loamy, well-draining soil mix. Water regularly to prevent the soil from drying out.

How do I prevent Miyama turnips from bolting?

To prevent bolting, avoid planting turnips in the heat of summer. Instead, aim to grow them in cooler temperatures and ensure they receive enough water and nutrients.

What are common pests for Miyama turnips, and how can I manage them?

Common pests include flea beetles and aphids. Using row covers can help protect young plants, and keeping the soil well-drained can prevent issues like clubroot. Regularly check your plants and remove any pests by hand or use organic insecticides if necessary. Companion planting with radishes can also help deter some pests.
