How to Grow Saffron Crocus in the United States

1. Understanding Saffron Crocus

Saffron crocus (Crocus sativus) is known for producing saffron, the world’s most expensive spice. It is a fall-blooming plant that requires specific conditions to thrive.

2. Growing Conditions

  • Climate: Saffron crocus is best suited for USDA hardiness zones 5 to 9. They prefer areas with hot, dry summers and well-draining soil.
  • Soil: Well-draining soil is essential, as saffron bulbs can rot in overly moist conditions. A sandy or loamy soil mix is ideal, with a pH around 6-7.

3. Best Time to Plant

  • Planting Time: Saffron corms should be planted in late summer to early fall (around late August to September). This timing allows the plants to establish roots before the winter and bloom in the fall.

4. Planting Saffron Crocus

  • Site Preparation: Choose a sunny location. Amend the soil with organic matter to improve drainage.
  • Planting Depth: Plant the corms about 4-6 inches deep and 4-6 inches apart. Cover them lightly with soil and water gently.

5. Watering and Care

  • Watering: After planting, water the corms lightly to help them settle. Once established, saffron crocus is drought-tolerant and requires minimal watering.
  • Fertilizing: A light application of a balanced fertilizer in early spring can promote growth.

6. Harvesting Saffron

  • Harvesting Time: The flowers will bloom in October or November. Each flower produces three red stigmas, which should be carefully harvested in the morning when the flowers are fully open.
