How to Grow Fennel
Growing fennel can be a rewarding experience. Below is a step-by-step guide to help you through the process.
Choosing the Right Variety
- Florence Fennel (Foeniculum vulgare var. azoricum): This type is grown for its bulb-like stem base.
- Herb Fennel (Foeniculum vulgare): This type is grown mainly for its leaves and seeds.
Planting Fennel
- Location: Choose a sunny location with well-drained soil. Fennel prefers soil with a pH between 6.0 and 7.0.
- Timing: Plant fennel seeds in early spring after the last frost or in late summer for a fall harvest.
- Spacing: Sow seeds about 1/4 inch deep and 12 inches apart. If growing Florence fennel, space rows about 18 inches apart to allow room for the bulbs to form.
- Watering: Keep the soil consistently moist but not waterlogged. Water regularly, especially during dry periods.
Caring for Fennel
- Thinning: Once the seedlings are a few inches tall, thin them out to maintain proper spacing.
- Weeding: Keep the area around the fennel free of weeds to reduce competition for nutrients and water.
- Feeding: Fennel doesn’t require heavy feeding, but you can add compost or a balanced fertilizer during the growing season to encourage healthy growth.
Growing Tips
- Companion Planting: Fennel can inhibit the growth of some other plants, so avoid planting it near dill, cilantro, or tomatoes. However, it can attract beneficial insects like ladybugs and lacewings.
- Pest Control: Fennel is generally pest-resistant, but watch for aphids or slugs. Use organic methods like neem oil or diatomaceous earth if needed.
Harvesting Fennel

Storing Fennel
- Bulbs: Store fennel bulbs in the refrigerator for up to a week. They can also be blanched and frozen for longer storage.
- Seeds: Store dried fennel seeds in an airtight container in a cool, dark place for up to a year.
