How to Grow Taro (in certain conditions) in North Dakota

Growing taro, a tropical plant known for its edible root and leaves, can be a rewarding experience, even in a state like North Dakota, which presents unique challenges due to its climate. With the right conditions, techniques, and care, you can successfully cultivate this versatile crop. This article explores how to grow taro in North Dakota, focusing on specific conditions that make it possible.

Understanding Taro

Taro (Colocasia esculenta) is native to Southeast Asia and thrives in warm, humid environments. It is cultivated mainly for its starchy corms and edible leaves, which are highly nutritious. The plant requires specific conditions to grow successfully, including:

Given these requirements, growing taro in North Dakota necessitates careful planning and implementation of strategies that simulate its preferred tropical conditions.

Choosing the Right Varieties

Not all taro varieties are created equal when it comes to growing in challenging climates. Some of the most suitable varieties for North Dakota include:

Selecting the right variety will significantly increase your chances of successful cultivation.

Site Selection

Sunlight Exposure

Choose a planting site that receives full sun for at least 6 to 8 hours a day. Taro requires significant light for photosynthesis and growth. Avoid areas shaded by trees or buildings.

Soil Quality

Taro thrives in rich, loamy soils with good drainage. The ideal pH level should range from 5.5 to 7.0. Conduct a soil test to ascertain nutrient levels and pH. Amend the soil with organic matter like compost or well-rotted manure to improve fertility and moisture retention.

Water Availability

Since taro loves moisture, having access to water is crucial. If possible, choose a location with a natural water source or plan for irrigation systems that can maintain consistent soil moisture levels.

Preparation Before Planting

Soil Preparation

Before planting, prepare the soil by tilling it to a depth of 12-15 inches. Incorporate organic matter and ensure good drainage by adding sand or perlite if your soil is heavy clay. Create raised beds if necessary to enhance drainage.

Seed Selection

You can start taro from corms or offsets. Choose healthy corms that are firm and free from rot or disease. Each corm should weigh at least 4 ounces and have one or more eyes (growing points). Cut larger corms into smaller pieces, ensuring each piece has at least one eye.

Planting Taro

Timing

In North Dakota, the growing season is relatively short, so timing is crucial. Aim to plant taro indoors in seed trays about 6-8 weeks before the last expected frost date (typically late March). Transplant seedlings outdoors after the danger of frost has passed and when nighttime temperatures consistently stay above 60°F.

Spacing

When planting outdoors, space corms about 3 feet apart in rows that are 3-4 feet apart. This spacing allows adequate airflow between plants and helps prevent disease spread.

Planting Depth

Plant each corm about 2-4 inches deep. Cover them lightly with soil but ensure they aren’t buried too deeply as this can hinder their growth.

Growing Conditions During the Season

Water Management

Water your taro regularly to keep the soil consistently moist but not waterlogged. During peak summer heat, you may need to water daily or every other day. Implementing a drip irrigation system can help maintain moisture without over-saturating the soil.

Fertilization

Feed your taro plants with a balanced fertilizer every 4-6 weeks throughout the growing season. A formula high in potassium will promote corm development. Organic fertilizers such as fish emulsion or seaweed extracts can also provide essential nutrients while enhancing soil structure.

Pest and Disease Control

Monitor your plants for common pests such as aphids, leafhoppers, and spider mites. Use integrated pest management (IPM) strategies involving natural predators or insecticidal soap when necessary.

Fungal diseases can affect taro due to excess moisture; ensure good airflow around plants by pruning crowded areas and avoiding overhead watering whenever possible.

Harvesting Taro

Taro typically takes about 7-12 months from planting to harvest time depending on the variety and growing conditions. Signs of readiness include yellowing leaves and dieback of foliage.

To harvest:

  1. Gently loosen the soil around the base of each plant using a garden fork.
  2. Carefully lift the corms from the ground, taking care not to damage them.
  3. Shake off excess soil and allow them to dry under shade before storage.

Storing Taro Corms

After harvesting, store your corms in a cool (50°F), dark place with good airflow until you are ready to use them or replant next season’s crop. Avoid exposure to direct sunlight, which can cause them to sprout prematurely.

Overwintering Taro in North Dakota

Due to North Dakota’s harsh winters, it’s typically best not to leave taro plants in the ground over winter unless you take specific measures for protection:

  1. Digging Up Corms: Before frost hits, dig up the corms to prevent freezing.
  2. Indoor Storage: Store them indoors in peat moss or sawdust until spring.
  3. Replanting: Replant them once the risk of frost has passed and temperatures warm again.

Conclusion

Growing taro in North Dakota requires careful planning, appropriate variety selection, attention to site conditions, and dedicated care throughout the growing season. By simulating tropical conditions as closely as possible—maintaining warmth, moisture levels, and nutrient-rich soil—you can cultivate this delicious crop successfully even amidst challenging climates. With patience and perseverance, you can enjoy homegrown taro that adds diversity and flavor to your meals while offering valuable health benefits!
