Shogoin is a versatile turnip variety grown for both its large roots and vibrant tops. The roots are white, globe-shaped, and about 5 inches across, making them ideal for a range of dishes. The tops are broad, serrated, and tender, with a texture that is perfect for cooking. Widely used in commercial greens production, this variety is both practical and productive.
Turnip Growing Guide
Outdoor Sowing (Directly in the Garden)
- Timing: Sow turnip seeds outdoors as soon as the soil can be worked in early spring, typically 2–4 weeks before the last frost date. For a fall harvest, sow seeds in late summer or early fall, about 6–8 weeks before the first expected frost.
- Location: Choose a sunny spot or an area with partial shade. Turnips grow best in loose, well-draining soil.
- Soil Preparation: Loosen the soil to a depth of 8–12 inches and incorporate compost or well-rotted manure to improve fertility and drainage. Turnips prefer slightly acidic to neutral soil with a pH of 6.0–7.0.
- Planting Seeds:
- Sow seeds 1/4–1/2 inch deep and 1–2 inches apart in rows.
- Space rows 12–18 inches apart for proper airflow and ease of harvesting.
- Thinning: Thin seedlings to 3–6 inches apart once they are 2–3 inches tall to give each plant room to grow.
- Watering: Keep the soil consistently moist but not waterlogged. Water deeply and regularly, especially during dry periods, to encourage tender roots.
General Care Tips for Turnips
- Sunlight: Provide full sun for best root development. Turnips can tolerate partial shade, especially in warmer climates.
- Watering: Water consistently to keep the soil evenly moist. Mulch around plants to retain moisture and suppress weeds.
- Fertilizing: Turnips are light feeders. Enrich the soil with compost before planting. Avoid over-fertilizing with nitrogen, as it can promote leafy growth at the expense of roots.
- Weeding: Keep the area weed-free to reduce competition for nutrients and moisture. Be careful not to disturb turnips’ shallow roots when weeding.
- Pest and Disease Control: Monitor for pests like flea beetles and aphids. Use row covers to protect young plants, and apply organic pest control methods if necessary. Ensure good airflow to prevent fungal diseases.
- Harvesting:
- For Roots: Harvest turnips when the roots are 2–3 inches in diameter, typically 30–60 days after sowing. Larger roots may become woody or bitter.
- For Greens: Harvest tender greens when they are 4–6 inches tall. You can cut the outer leaves while allowing the inner leaves to grow.
- Storage: Store harvested turnip roots in a cool, humid place such as a refrigerator or root cellar. Remove the greens before storing roots. Turnips can last up to 4–5 months if stored properly.
