USDA Hardiness Zones

3, 4, 5, 6, 7

USDA Zones 3-7 - Caraway is a hardy biennial herb that requires a cold period for vernalization (the process that induces flowering). It grows vegetative foliage in the first year and produces flowers and seeds in its second year.

Best Performance - The plant thrives in Zones 3-7, where cold winters provide the necessary chilling period to ensure robust flowering and seed production in the second summer.

Northern Zones (3-5) - This is the ideal climate for caraway. It easily survives cold winters and performs reliably, yielding a substantial seed harvest in its second year.

Hot Climate Zones (8+) - Caraway generally does not perform well in regions with mild winters and intense summer heat. The lack of a sufficient cold period can prevent the plant from flowering, making seed production unlikely. In these areas, it may be grown as an annual for its leafy foliage only.

Soil Temperature - Seeds germinate well in cool soil, with optimal temperatures between 55-70 degrees F. Spring or autumn sowing is recommended.

Growing Season - Caraway requires two full seasons to complete its life cycle. The first year is dedicated to root and foliage growth. Following a winter dormancy period, the plant flowers in late spring of the second year, with seeds ready for harvest by mid-summer.

Planting Tips

When to Sow:
For best results, direct sow seeds into the garden in either early spring as soon as the soil is workable, or in late summer/early autumn. Fall-sown plants develop a strong root system before winter, often leading to a more vigorous plant in the second year.

Sowing and Germination:

Seed Depth: Sow seeds approximately 1/4 to 1/2 inch deep.

Soil: Plant in a location with well-drained, loamy soil and full sun exposure. Caraway develops a long taproot and does not transplant well, making direct sowing the preferred method.

Germination: Keep the seedbed consistently moist. Germination typically occurs within 7-14 days in appropriate conditions.

Spacing and Thinning:

Sow seeds approximately 2-3 inches apart.

Once seedlings have developed their first true leaves, thin them to a final spacing of 8-12 inches apart to allow ample room for development.

Ongoing Care:

Light: Caraway requires full sun (a minimum of 6 hours of direct sunlight) for the best growth and seed production.

Water: Water regularly during germination and establishment. Once mature, its deep taproot provides moderate drought tolerance, but it will benefit from supplemental watering during extended dry periods.

First-Year Care: In the first year, the plant will form a low-growing rosette of leaves. Keep the area free of weeds to reduce competition. Leaves can be harvested sparingly.

Second-Year Care: The plant will send up a tall flower stalk in the late spring of its second year. The plant may reach 2-3 feet in height and become top-heavy; staking may be necessary in windy locations.

Harvesting: Harvest seeds in the second summer after the flowers have faded and the seed heads have turned brown and dry. Cut the entire stalk, and hang it upside down in a warm, dry place with a paper bag tied around the head to catch the mature seeds as they fall.
