What Are Turnips?
Turnips (Brassica rapa subsp. rapa) are biennial plants grown as annuals for their edible roots and leaves. Originating from Europe and Western Asia, turnips have been cultivated for centuries and are a staple in various cuisines around the world. They are known for their large, round to oval-shaped roots and broad, green leaves.
Key Characteristics:

- Leaves: Broad, dark green leaves that are also edible and highly nutritious.
- Roots: Large, bulbous roots that vary in size, color (typically white with purple markings), and texture.
- Flowers: Yellow, four-petaled flowers that form clusters if allowed to bolt (go to seed).
What Are Parsnips?
Parsnips (Pastinaca sativa) are perennial root vegetables closely related to carrots. Native to Eurasia, parsnips have been cultivated for thousands of years and are especially popular in European cuisines. They are distinguished by their creamy white color and sweet, nutty flavor that intensifies after exposure to frost.
Key Characteristics:
- Growth Habit: Tall, erect plants that can reach heights of up to 3 feet (90 cm).
- Leaves: Feathery, fern-like green leaves that provide a lush appearance.
- Roots: Long, tapering roots that are creamy white and smooth when young, becoming sweeter and more flavorful as they mature.
- Flowers: Umbel-shaped clusters of small white flowers that attract pollinators like bees.

Planting Turnips and Parsnips
Successful cultivation of turnips and parsnips begins with proper planting techniques. Understanding the specific needs of each vegetable ensures healthy growth and optimal yields.
Sowing Seeds
- Turnips:
- Timing: Sow seeds in early spring or late summer for fall harvests.
- Depth: Plant seeds about ½ inch deep.
- Spacing: Space seeds 2 inches apart in rows 12-18 inches apart.
- Parsnips:
- Timing: Sow seeds in early spring or late summer; require a long growing season.
- Depth: Plant seeds about ½ inch deep.
- Spacing: Space seeds 2-3 inches apart in rows 12-18 inches apart.
Spacing and Depth
- Turnips:
- Maintain adequate spacing to allow for root expansion.
- Thin seedlings to about 4-6 inches apart once they emerge to prevent overcrowding.
- Parsnips:
- Ensure sufficient spacing to accommodate their long roots.
- Thin seedlings to about 3-4 inches apart once they have developed several true leaves.
Soil Preparation
- Turnips:
- Soil Enrichment: Incorporate compost or well-rotted manure to enhance soil fertility.
- Soil Structure: Ensure the soil is loose and friable to allow easy root development.
- Parsnips:
- Deep Tilling: Parsnips require deep, loose soil to grow straight and long roots.
- Soil Amendments: Add sand or fine gravel to improve soil drainage and prevent hardening.
Growing Conditions
Providing the right growing conditions is essential for the healthy development of turnips and parsnips.
Sunlight
- Turnips:
- Require full sun to partial shade.
- Aim for at least 6 hours of direct sunlight daily.
- Parsnips:
- Thrive in full sun but can tolerate partial shade.
- Ensure consistent sunlight exposure for optimal growth.
Watering
- Turnips:
- Keep the soil consistently moist, especially during germination and root development.
- Avoid overwatering to prevent root rot and cracking.
- Parsnips:
- Require regular, consistent watering to maintain soil moisture.
- Insufficient watering can lead to tough, woody roots and increased bitterness.
Fertilizing
- Turnips:
- Apply a balanced fertilizer at planting and mid-season to support growth.
- Avoid excessive nitrogen, which can promote foliage over root development.
- Parsnips:
- Generally require minimal fertilization; excess nitrogen can cause spindly growth.
