How to Grow Taro Root in Colorado

Taro (Colocasia esculenta) is an ancient tropical root vegetable that has been cultivated for thousands of years. While it flourishes in warm, humid climates, growing taro in Colorado can be a rewarding challenge for adventurous gardeners. With a few considerations and the right techniques, you can successfully cultivate this nutritious and versatile plant. This guide will walk you through the steps to grow taro root in Colorado.

Understanding Taro Root

Taro is known for its heart-shaped leaves and starchy corms, which are rich in carbohydrates, fiber, and essential nutrients. The plant is not only edible but also has cultural significance in various cuisines around the world. Understanding its growing conditions is critical, especially in Colorado’s diverse climate.

Climate Considerations

Taro is native to tropical regions and requires a warm climate to thrive. Colorado’s climate varies significantly from region to region. While some areas may experience hot summers, the temperature can drop quickly, especially at night. Here are some key climate factors to consider:

Choosing the Right Variety

When selecting taro varieties for cultivation, consider options well-suited for container gardening or smaller plots if you have limited space. Some popular varieties include:

  1. Bun long: Known for its high yield and resistance to pests.
  2. Bun Khuong: Has a sweet flavor and is often sought after for culinary uses.
  3. Hawaiian poi taro: Excellent for making poi and other traditional dishes.

It’s best to choose varieties that adapt well to temperate climates while still providing the flavors you enjoy.

Preparing Your Growing Area

Selecting a Location

Choose a site that receives full sun for at least six hours daily. The ideal location should also have access to water and be sheltered from strong winds that can dry out plants or damage their leaves. If possible, consider creating a microclimate with windbreaks or using row covers during cooler weather.

Soil Requirements

Taro thrives in rich, loamy soil with excellent drainage capabilities. However, it also appreciates moisture-retentive properties. Here’s how to prepare your soil:

  1. Soil Testing: Conduct a soil test to check pH levels (ideal pH between 5.5–7) and nutrient content.
  2. Amendments: Add organic matter such as compost or well-rotted manure to improve soil quality.
  3. Drainage: Ensure that your soil drains well by incorporating sand or perlite if necessary.

Container Gardening

If ground planting isn’t feasible due to poor soil conditions or limited space, consider using containers or raised beds filled with suitable soil mix. Make sure that containers are large enough (minimum of 5 gallons) to allow root expansion.

Planting Taro Root

Propagation

Taro can be grown from corms (the underground storage organ) rather than seeds, which are less common in cultivation. You can often find corms at local garden centers or specialty stores.

Steps for Planting:

  1. Corm Selection: Look for firm, healthy corms with visible eyes (growth buds).
  2. Pre-soaking: Soak the corms in water overnight before planting to encourage sprouting.
  3. Cutting Corms: If planting larger corms (e.g., over 6 inches), cut them into pieces with at least one eye per piece.
  4. Plant Depth: Plant corms about 3–4 inches deep in the prepared soil, spacing them 18–24 inches apart.

Timing

In Colorado, plant taro after the last frost date—typically between late May and early June—to ensure a longer growing season.

Watering and Care

Irrigation Needs

Taro requires consistent moisture throughout its growth cycle but does not tolerate standing water for prolonged periods. Here are irrigation tips:

Fertilization

Taro benefits from regular feeding during the growing season:

  1. Use a balanced fertilizer high in potassium—ideal for root development—following package instructions for application rates.
  2. Alternatively, apply liquid fertilizers every few weeks during active growth.

Pest and Disease Control

While taro is generally resilient, it can attract pests like aphids and spider mites if not managed properly.

Harvesting Taro Root

Harvesting typically occurs between 7–12 months after planting when the leaves begin to yellow and die back.

Signs of Readiness

Look for signs such as:
– Yellowing foliage
– Stunted growth
– Leaves wilting downwards

Harvest Process

  1. Carefully dig around the base of the plant using a spade or fork.
  2. Lift the corms out gently without damaging them.
  3. Clean off excess soil but avoid washing them until you are ready to use them.

Storing Taro Root

After harvesting, store corms in a cool, dark place with good airflow—ideally between 50°F and 60°F (10°C – 15°C). Use them within a few weeks as they don’t store well over long periods unlike potatoes or carrots.

Culinary Uses of Taro Root

Taro root is a versatile ingredient used in various dishes worldwide—from traditional Hawaiian poi to savory soups and stews or even desserts like taro ice cream. Here are some popular ways to enjoy it:

Conclusion
