How To Grow Fennel

Growing fennel in your garden can provide you with a fresh supply of this flavorful herb. Here's a detailed guide on how to grow fennel:

1. Choosing the Right Planting Method:

  • Fennel can be grown from seeds directly in the garden or started indoors for later transplanting. The choice depends on your climate, growing zone, and personal preference.

2. Direct Sowing Fennel Seeds:

  • If you have a long growing season or live in a warm climate, consider planting fennel seeds directly in the garden as close to your last spring frost date as possible.
  • Space the fennel seeds about 10 - 12 inches apart to allow each fennel plant ample space to thrive.
  • Fennel seeds typically germinate within 8 to 12 days after planting.

3. Starting Fennel Indoors:

  • In regions with shorter growing seasons or cooler climates, starting fennel indoors can be a good option. Begin sowing fennel seeds indoors in a sunny location about 4 weeks prior to your last expected frost date.
  • After starting fennel indoors, be sure to harden off the seedlings. Gradually expose them to outdoor conditions, such as sunlight and temperature variations, before transplanting them into your garden. This acclimates the seedlings to the outdoor environment.

4. Understanding Fennel's Growing Habits:

  • Fennel is naturally a warm climate or Mediterranean crop. In cooler climates, it's typically grown as an annual due to its sensitivity to frost. However, in regions with mild winters (growing zones 6-10), fennel can survive the winter if you avoid harvesting the bulb.
  • In growing zones 2-5, fennel can be cultivated both in the spring and again in the fall as a biennial. This means it completes its lifecycle over two years.

5. Plant Care:

  • Ensure that your fennel plants receive adequate sunlight, at least 6-8 hours a day. Well-draining soil with good organic matter content is essential for healthy fennel growth.
  • Regularly water your fennel plants to keep the soil consistently moist. Avoid waterlogged conditions, as fennel prefers well-drained soil.

6. Harvesting Fennel:

  • The timing of your fennel harvest depends on your intended use. If you plan to eat fennel raw, it's best to harvest the bulbs before they become too large. Smaller bulbs, approximately three inches in width, are more tender and have a milder flavor.
  • In general, you can start harvesting your fennel bulbs around 65 days after planting. However, you can also harvest fennel fronds (foliage) and seeds at various stages of growth for culinary use.

7. Pest and Disease Management:

  • Keep an eye on your fennel plants for common garden pests like aphids and caterpillars. Hand-picking pests or using organic pest control methods can help protect your fennel crop.
  • Proper spacing and good air circulation can also help prevent diseases like fungal infections.

How To Cook Fennel

Fennel is delicious raw and cooked so many, but first you need to trim off the stalks and wash the bulb! The upper fronds are used as a wonderful accent added to salads. The fennel BULB is the main part for cooking!

After rinsing the exterior of the fennel bulb off, carefully cut off a thin layer at the bottom to remove any old tuff stem.

There are so many recipes for fennel, so I will share just a couple of my favorite ways to eat fennel here.

Roasted Fennel: Fennel can be roasted alone or with other fresh vegetables. To roast the fennel, cut the bulb in half, then cut halves into quarters. After that, sprinkle with salt and olive oil and roast in the oven at 400 degrees for 30-40 minutes till tender! Then let cool for a couple of minutes and ENJOY!

You can also use fennel anyway that you would use celery and it will add lovely mild licorice or anise flavor. After the fennel is cooked it turns sweet and caramelly like cooked onions.

Some of the best ways to incorporate cooked fennel is in stir fry, soups, stews, and stuffing. Your imagination is the limit when cooking fennel!

Preparing Fennel Raw

When you are preparing fennel raw, you'll want to choose smaller bulbs because they are more tender. Raw fennel has a texture like raw celery, and you can use it in similar ways!

Fennel is also delicious raw! You can use your fennel raw by slicing the bulb THIN, and then adding it to your favorite salad. Fennel is also wonderful in chicken salad, potato salad, and tuna sandwiches!

Or, make a FENNEL Salad! Add THINLY sliced fennel bulb, or shaved fennel bulb, orange slices, sliced olives, and your favorite citrus dressing! Olive oil, lemon juice, and thyme make a nice fennel salad dressing.

Note: Fennel oil and seeds are good used for flavoring too!
