Sow and Plant :Start seeds indoors, or sow in shallow furrows filled with potting soil. Thin seedlings to 12 inches apart when they are 3 weeks old. Chop the pulled seedlings into salads.
When the bulb is the size of an egg, surround it with 6 inches of loose mulch to help it plump up.

Spacing : Single Plants: 11″ (30cm) each way; Rows: 9″ (25cm) with 1′ 1″ (35cm) row gap

Feeding : Feed every 3 weeks with a liquid organic fertilizer, and use a rich, biodegradable mulch such as grass clippings.

Harvesting :Snip tender young leaves as needed in the kitchen. When the bulbs reach 3 inches in diameter, pull them and store in the refrigerator.

Time to harvest: days

Troubleshooting :Grows best in cool weather. In some climates, fennel grows better in fall than in spring.

Notes :Fennel is allelopathic to most garden plants, inhibiting growth, causing to bolt, or actually killing many plants. When growing together a higher ratio of fennel to dill provides the highest profit. Dill has a stabilizing effect on the fennel seed. Because it attracts syrphidae it reduces aphids through predation
