How to Grow Cilantro in Nebraska: A Step-by-Step Guide

Cilantro (Coriandrum sativum), also known as coriander, is a popular herb used in a variety of dishes from salsa to curries. Growing cilantro in Nebraska can be a bit of a challenge due to the state’s hot summers, but with proper planning, you can cultivate a healthy, flavorful crop.

1. Choosing the Right Cilantro Variety

There are several varieties of cilantro that perform well in Nebraska’s climate. Some top choices include:

  • Slow Bolt Cilantro: A variety bred to delay bolting (going to seed), which is common in hot weather.
  • Santo Cilantro: Known for its slow bolting and large leaves, making it ideal for warm climates.
  • Leisure Cilantro: Another slow-bolting variety that is excellent for culinary uses.

2. Timing Your Planting

Nebraska’s hot summers make timing critical when planting cilantro.

  • Cool-season herb: Cilantro grows best in temperatures between 50°F and 85°F. In Nebraska, aim to plant cilantro in early spring (March or April) or late summer (August), so it can grow during cooler weather.
  • Succession Planting: Since cilantro can bolt quickly in the heat, consider planting seeds every 2-3 weeks for a continuous harvest.

3. Choosing the Right Location

Cilantro prefers cool weather but still needs plenty of sunlight.

  • Sunlight: Plant cilantro in a spot that gets at least 4-6 hours of sunlight daily, ideally with some afternoon shade to protect it from the scorching Nebraska sun.
  • Soil: Cilantro thrives in well-drained, moderately rich soil with a neutral pH (6.5-7.5). Amend the soil with compost before planting to improve fertility and moisture retention.

4. Planting Cilantro

  • Sowing Depth: Plant seeds about 1/4 inch deep, directly into the soil.
  • Spacing: Space plants 6-8 inches apart to allow for healthy growth.
  • Watering: Keep the soil evenly moist but not waterlogged. Cilantro is shallow-rooted, so it’s important to water consistently to prevent stress.

5. Caring for Your Cilantro

  • Fertilizing: Cilantro does not need heavy fertilization. Side-dress with compost or use a balanced fertilizer if growth seems slow.
  • Mulching: To keep the roots cool and moist, mulch around cilantro plants. This is especially helpful in Nebraska’s warmer weather to reduce heat stress and conserve moisture.
  • Bolting Prevention: To delay bolting, give cilantro some afternoon shade and keep the soil evenly moist. Once cilantro bolts, the leaves become bitter and the plant focuses on producing seeds.

6. Harvesting Cilantro

  • Harvest leaves when the plant is about 6 inches tall, cutting individual stems as needed. Regular harvesting encourages bushier growth.
  • Cilantro seeds (Coriander): If the plant bolts, you can allow the seeds to mature and harvest them. These seeds are coriander, another versatile herb used in cooking.

7. Managing Pests and Diseases

Cilantro is generally pest-resistant but may face occasional issues in Nebraska.

  • Pests: Aphids and whiteflies may attack cilantro. Use insecticidal soap or hose off plants to manage them.
  • Diseases: Powdery mildew and bacterial leaf spot can affect cilantro in humid conditions. Good air circulation and well-drained soil can help prevent these problems.

Conclusion

Growing cilantro in Nebraska requires careful attention to timing and temperature management. By planting in cooler seasons and providing proper care, you can enjoy fresh cilantro for months. Succession planting and choosing slow-bolting varieties will help ensure a continuous harvest in Nebraska’s fluctuating weather.
