How to Grow Turnips in Washington

Turnips are a versatile and nutritious root vegetable that can thrive in the diverse climates of Washington state. With their crisp texture and earthy flavor, turnips can be enjoyed roasted, mashed, or even raw in salads. Whether you’re an experienced gardener or a beginner, growing turnips can be a rewarding experience. This article will guide you through the essential steps to successfully cultivate turnips in Washington.

Understanding the Climate

Washington state has a varied climate, ranging from the temperate coastal regions to the arid eastern part of the state. Generally, turnips grow best in cooler temperatures between 50°F to 75°F (10°C to 24°C).

Coastal Regions

If you’re in the coastal areas like Seattle or Tacoma, you’ll find that the maritime climate allows for a longer growing season. Turnips can be planted in early spring for a late spring harvest or in late summer for a fall harvest.

Eastern Washington

In eastern Washington, where summers can be hot and dry, timing your planting is crucial. To avoid the heat, aim for early spring or late summer planting, allowing the roots time to mature before the cold winter sets in.

Choosing the Right Variety

Selecting the right variety of turnip is essential for successful growth. Some popular varieties suited for Washington include:

Consider your intended use—whether you want fresh eating, storage, or cooking—to select the best variety.

Soil Preparation

Turnips thrive in well-drained soil rich in organic matter. Here’s how to prepare your soil:

Testing Soil pH

The ideal soil pH for growing turnips is between 6.0 and 7.0. Conduct a soil test to determine your soil’s pH level. If it’s too acidic, consider adding lime; if it’s too alkaline, sulfur can help lower the pH.

Amending Soil

Incorporate plenty of organic matter into your soil before planting by adding compost or well-rotted manure. This will improve soil structure and nutrient levels.

Tilling the Soil

Loosen the soil to a depth of at least 12 inches (30 cm) by tilling or turning it over with a garden fork. This ensures adequate drainage and root development, which are critical for healthy turnip growth.

Planting Turnips

Timing and method are key when it comes to planting turnips.

When to Plant

How to Sow Seeds

  1. Row Spacing: Create rows that are about 12-18 inches (30-45 cm) apart.
  2. Seed Depth: Sow turnip seeds about half an inch (1.25 cm) deep.
  3. Seed Spacing: Space seeds about 2-4 inches (5-10 cm) apart within each row.
  4. Watering: After sowing, water gently to ensure good seed-to-soil contact.

Watering and Care

Proper care is essential for healthy turnip development.

Watering Requirements

Turnips require consistent moisture throughout their growing period. Aim for about 1 inch (2.5 cm) of water per week, either through rainfall or irrigation. Avoid letting the soil dry out completely as this can lead to bitter-tasting roots.

Weeding and Mulching

Weeds compete with your turnips for nutrients and water. Regularly check your garden beds and remove weeds by hand or with a hoe. Applying mulch can help suppress weeds, retain moisture, and regulate soil temperature.

Fertilization

Turnips might benefit from additional nutrients during their growth phase.

Choosing Fertilizer

A balanced all-purpose fertilizer can promote healthy growth:

  1. Application Timing: Fertilize at planting time and again when plants are about 4 inches tall (10 cm).
  2. Amount: Follow package instructions for application rates based on your soil’s nutrient needs.

Pest and Disease Management

Being vigilant against pests and diseases will help ensure a bountiful harvest.

Common Pests

  1. Aphids: These small insects can damage leaves but can be controlled with insecticidal soap or by introducing beneficial insects like ladybugs.
  2. Flea Beetles: These tiny beetles create small holes in leaves; row covers can help protect young plants from infestations.

Diseases

Turnips may suffer from diseases like downy mildew or root rot:

Harvesting Turnips

Knowing when to harvest is crucial for maximum flavor and texture.

Harvest Timeframe

Turnips are typically ready for harvest between 30 to 60 days after planting, depending on variety and growing conditions:

How to Harvest

  1. Loosen the soil around the roots gently using a fork.
  2. Pull up each turnip carefully to avoid breaking them.
  3. Cut off the greens immediately after harvesting if you plan on storing them; this will enhance shelf life.

Storing Turnips

To store harvested turnips effectively:

  1. Remove any excess dirt but do not wash them until you’re ready to use them.
  2. Store them in a cool, dark place such as a root cellar or refrigerator.
  3. Keep them wrapped in plastic bags or containers with vents to maintain humidity without rot.
