How to Grow Parsnips in New Mexico

Growing parsnips in New Mexico can be a rewarding endeavor. These unique vegetables thrive in cooler climates, making them well-suited for the state’s mild winters and varied elevations. This article will guide you through every step of growing parsnips, from selecting the right variety to harvesting your crop.

Understanding Parsnips

Parsnips (Pastinaca sativa) are root vegetables closely related to carrots and parsley. They are known for their sweet, nutty flavor that intensifies after exposure to frost. Rich in vitamins and minerals, parsnips are an excellent addition to any garden and culinary repertoire.

Benefits of Growing Parsnips

Nutritional Value: Parsnips are high in fiber, vitamins C and K, and several important minerals.
Versatility: They can be roasted, mashed, or used in soups and stews.
Cold Hardiness: Their ability to withstand frost allows them to be harvested well into the winter months.

Choosing the Right Variety

When selecting parsnip seeds, consider varieties that perform well in New Mexico’s climate. Here are a few recommended types:

Hollow Crown: A classic variety with a sweet flavor that thrives in cooler temperatures.
Giant Cross: Known for its large roots and high yield, ideal for home gardeners.
Javelin: This variety is more resistant to disease and produces smooth, long roots.

Preparing Your Soil

Parsnips prefer deep, loose soil that allows their roots to grow without restriction. Follow these steps to prepare your soil:

Soil Testing

Test pH Levels: Parsnips thrive in slightly acidic to neutral soil (pH 6.0 – 7.0). You can purchase a home soil testing kit or send samples to a local extension service.
Amend Accordingly: Depending on the test results, you may need to add lime (to raise pH) or sulfur (to lower pH).

Soil Preparation

Clear the Area: Remove any weeds, rocks, or debris from the planting area.
Tilling: Till your garden bed to a depth of at least 12 inches to ensure good drainage and root development.
Organic Matter: Incorporate compost or well-rotted manure into the soil to improve fertility and structure.

Planting Parsnips

Timing is crucial for growing parsnips successfully in New Mexico. These vegetables should be planted directly into the ground as they do not transplant well.

Ideal Planting Time

In New Mexico, parsnips can be sown either in early spring or late summer for a winter harvest. The best months for planting are:

Spring Planting: Late March to early April
Fall Planting: Late July to mid-August

Sowing Seeds

Row Spacing: Create rows approximately 12-18 inches apart.
Seed Depth: Sow seeds about 1/2 inch deep; cover lightly with soil.
Seed Density: Space seeds 2-4 inches apart within each row.

After sowing, water the area gently to avoid displacing the seeds.

Caring for Your Parsnip Crop

Once your seeds have germinated, which typically takes about 2-3 weeks, proper care is essential for healthy growth.

Watering

Parsnips require consistent moisture during their growing period:

Water deeply once a week, allowing the top inch of soil to dry out between watering.
During particularly hot spells or dry periods, increase watering frequency.

Weeding

Weeds can quickly compete with young parsnip plants:

Hand-pull weeds carefully around the plants when they are still small.
Consider mulching around the plants with straw or grass clippings to suppress weed growth while retaining moisture.

Fertilization

Parsnips do not need heavy fertilization:

Apply a balanced organic fertilizer at planting time.
A light side dressing of nitrogen fertilizer can be applied midway through the growing season if necessary.

Pest and Disease Management

While parsnips are generally resistant to pests and diseases, it’s still essential to keep an eye out for common issues.

Common Pests

Carrot Rust Fly: Look for small holes in leaves; use floating row covers as a preventive measure.
Aphids: Regularly inspect the undersides of leaves; wash them off with water or apply insecticidal soap if necessary.

Diseases

Parsnips can succumb to fungal diseases like powdery mildew:

Ensure good air circulation by spacing plants properly.
Avoid overhead watering; water at the base of the plants instead.

Harvesting Parsnips

One of the most satisfying parts of growing parsnips is harvesting them!

Optimal Harvest Time

Parsnips are usually ready for harvest about 120 days after planting. However, they can remain in the ground throughout winter:

The best time to harvest is after the first frost when their sweetness peaks.

How to Harvest

Gently loosen the soil around each plant using a garden fork.
Grasp the leaves near the base and pull upward carefully to avoid breaking the root.
Trim off foliage once harvested but leave a bit of stem attached for easy handling.

Storing Your Parsnips

Proper storage ensures that your parsnips retain their flavor and nutritional value:

Cool Storage: Keep harvested parsnips in a cool, dark place with high humidity – ideally between 32°F and 40°F.
Moist Sand Method: Store them buried in moist sand within a root cellar or similar environment to prevent dehydration.
Refrigeration: For shorter-term storage, place them unwashed in plastic bags in your refrigerator’s crisper drawer.

Culinary Uses for Parsnips

Once harvested, there are numerous ways you can enjoy your homegrown parsnips:

Roasted: Toss with olive oil and seasonings before roasting until golden brown.
Soups and Stews: Add diced parsnips for natural sweetness and flavor depth.
Mashed: Boil until tender and mash with butter or cream for a delicious side dish.

Conclusion

Growing parsnips in New Mexico presents an exciting opportunity for both novice and experienced gardeners alike. With proper planning, care, and harvesting techniques, you can enjoy this nutritious vegetable throughout winter while expanding your culinary horizons. Whether you choose to plant them in spring or late summer, following these guidelines will help you yield a bountiful crop of sweet and flavorful parsnips ready for your kitchen creations!
