Why Grow Parsnips in a Greenhouse?
Growing parsnips in a greenhouse offers several advantages:
- Extended Growing Season: Greenhouse cultivation allows you to extend the growing season for parsnips, harvesting them even when outdoor temperatures are too cold.
- Controlled Environment: A greenhouse provides a controlled environment, protecting your plants from harsh weather conditions and pests.
- Consistent Conditions: You can regulate temperature, humidity, and light levels, ensuring optimal conditions for parsnip growth.
- Early Harvest: With a greenhouse, you can start parsnip seeds earlier in the season and enjoy an early harvest.
Selecting the Right Parsnip Variety
Choosing the right parsnip variety is crucial for success. Consider these factors:
- Maturity: Choose varieties that mature within the time frame you have available. Some varieties mature in 90 days, while others take up to 120 days.
- Size: Select varieties that produce the size of parsnips you desire.
- Flavor: Different varieties have varying sweetness and flavor profiles. Experiment to find your favorite.
Preparing Your Greenhouse
Before planting, prepare your greenhouse to ensure optimal conditions for parsnip growth:
- Soil Preparation: Parsnips prefer loose, well-drained soil with a pH of 6.0 to 7.0. Amend your soil with compost or aged manure to improve drainage and fertility.
- Light: Parsnips need at least 6 hours of sunlight per day. Supplement with artificial lighting if needed, especially during winter months.
- Ventilation: Ensure adequate ventilation to prevent humidity buildup. Open windows or vents to allow for air circulation.
- Temperature: Maintain a consistent temperature of 60-70°F (15-21°C) for optimal growth.
Planting Your Parsnip Seeds
Once your greenhouse is ready, follow these steps to plant your parsnip seeds:
- Direct Sowing: Parsnips are best sown directly into the soil. Avoid transplanting as it can damage the taproot.
- Spacing: Space seeds 1-2 inches apart and 12-18 inches between rows.
- Depth: Sow seeds 1/2 inch deep.
- Watering: Water regularly, keeping the soil consistently moist.
Caring for Your Parsnip Plants
Once your parsnip seeds have germinated, provide the following care:
- Watering: Water deeply and consistently, but avoid overwatering.
- Weeding: Remove weeds regularly to prevent competition for nutrients and water.
- Thinning: Thin seedlings to 4-6 inches apart once they have a few true leaves.
- Fertilizing: Apply a balanced fertilizer every 4-6 weeks.
Harvesting Your Parsnip Bounty
Parsnips are ready for harvest when they reach the desired size, typically 6-8 inches in length.
- Harvesting: Use a garden fork or trowel to gently lift the parsnips from the soil.
- Storing: Parsnips can be stored in a cool, dry place for several months.

The satisfaction of harvesting your own parsnips is unparalleled. These versatile roots can be enjoyed in countless ways:
- Roasted: Roasted parsnips are a delicious side dish, offering a sweet and earthy flavor.
- Mashed: Mashed parsnips are a creamy and flavorful alternative to mashed potatoes.
