1. Choosing the Right Variety of Parsnips
The first step in growing parsnips is selecting the right variety for your needs. Popular choices include:
1. ‘Gladiator’:
- Known for its resistance to canker and smooth, long roots.
2. ‘Tender and True’:
- A classic heirloom variety with excellent flavor.
3. ‘Javelin’:
- Ideal for heavy soils and produces uniform roots.
4. ‘Hollow Crown’:
- A traditional variety with a sweet, nutty taste.
2. When to Plant Parsnips
Timing is crucial for parsnip cultivation:
1. Early Spring:
- Sow seeds from March to May when the soil temperature is above 10°C (50°F).
2. Long Growing Season:
- Parsnips take 16–20 weeks to mature, making them a long-season crop.
3. Frost Exposure:
- Leave parsnips in the ground until after the first frost to enhance their sweetness.
3. Preparing the Soil for Parsnips
Parsnips thrive in deep, loose, and fertile soil. Follow these steps for soil preparation:
1. Remove Stones:
- Clear the soil of rocks and debris to prevent forked roots.
2. Loosen the Soil:
- Dig to a depth of at least 30 cm (12 inches) to allow roots to grow straight.
3. Add Organic Matter:
- Incorporate well-rotted compost or manure to enrich the soil. Avoid fresh manure, as it can cause deformities.
4. pH Level:
- Aim for a slightly acidic to neutral soil pH (6.0–7.0).
4. How to Sow Parsnip Seeds
Parsnip seeds require careful handling due to their slow germination and short viability:
Step 1: Sow Directly:
- Sow seeds directly into the prepared bed, as parsnips dislike transplanting.
Step 2: Create Rows:
- Space rows 30 cm (12 inches) apart and sow seeds thinly, about 1 cm deep.
Step 3: Cover Lightly:
- Cover seeds with a fine layer of soil and water gently.
Step 4: Patience is Key:
- Germination can take 2–3 weeks, so keep the soil moist and weed-free.
5. Caring for Parsnips
Once germinated, parsnips require minimal attention:
1. Watering:
- Water consistently, especially during dry spells, to prevent woody roots.
2. Thinning:
- Thin seedlings to 10–15 cm (4–6 inches) apart when they are 5 cm tall.
3. Weeding:
- Keep the area weed-free to reduce competition for nutrients.
4. Mulching:
- Apply organic mulch to retain moisture and suppress weeds.
6. Common Problems When Growing Parsnips
1. Poor Germination:
- Cause: Old seeds or cold soil.
- Solution: Use fresh seeds and sow when the soil warms up.
2. Forked Roots:
- Cause: Stony soil or fresh manure.
- Solution: Prepare soil thoroughly and avoid using fresh manure.
3. Canker:
- Cause: Fungal infection, often in wet conditions.
- Solution: Grow resistant varieties and avoid waterlogging.
4. Pests:
- Problem: Carrot flies may damage roots.
- Solution: Use fine mesh or fleece to protect plants.
7. Harvesting Parsnips
Knowing when and how to harvest ensures the best flavor and texture:
1. Timing:
- Harvest parsnips 16–20 weeks after sowing, or leave them in the ground until after the first frost for sweeter roots.
2. Tools:
- Use a garden fork to lift parsnips carefully, avoiding damage to the roots.
3. Storage:
- Store parsnips in a cool, dark place or in a box of damp sand to keep them fresh.
