When to Plant Fennel Seeds
Sow seeds in the Spring once soil has begun to warm, and the threat of frost has passed. Ideal soil temperatures will be between 50-70°F.
Where to Plant Fennel Seeds
Choose Fertile, moist, and well-draining soil. Fennel does best in Full Sun conditions. Avoid planting in areas where you have planted dill or coriander, as these varieties can easily cross-pollinate with one another. Also, Fennel can inhibit the growth of tomatoes and beans, so they shouldn't be planted nearby to one another.
How to Plant Fennel Seeds
Soak your Fennel seeds for a day or two before sowing to help ensure better germination. Direct sow seeds, as Fennel is not a good variety for transplanting. Plant seeds in rows about 10-12 inches apart, with space between rows at 13 inches. Seeds will germinate in approximately 7-14 days. Once seedlings are about 6 inches tall, thin out to a spacing of 12-18 inches.
How to Harvest Fennel
Fennel can be harvested as needed and used fresh. Regular harvesting will encourage new growth as well.
