What is Fennel?
Fennel is a versatile herb that’s native to the Mediterranean region, but it can be found all over the world. It’s a perennial plant that can grow up to 3-5 ft tall. The bulb, stalks, and fronds of fennel are all edible, and they have a delicate anise or licorice-like flavor.
This herb is rich in vitamins and minerals, particularly vitamin C and potassium. It is also a good source of antioxidants, which help to protect the body against damage from free radicals. The seeds of the fennel are used as a spice in Mediterranean, Indian, and Middle Eastern cuisine, and the bulb is often used in salads, soups, and stews.
Fennel is also used in traditional medicine and in herbal teas and essential oils, due to its anti-inflammatory, antioxidant and digestive properties.
Varieties of Fennel
There are two main varieties of fennel: sweet fennel and Florence fennel.
· Sweet Fennel
Also known as common fennel or wild fennel, is a hardy perennial herb that can grow up to 6 feet tall. It has thin, green stalks and delicate, feathery leaves. The seeds, leaves, and bulbs of sweet fennel are all edible and are commonly used in cooking.

Also known as finocchio, is a variety of fennel that’s grown for its bulbous base. Florence fennel is a biennial plant and is typically grown as an annual. The bulb, stalks, and leaves are all edible and have a slightly sweeter and more delicate flavor than sweet fennel.

History of Fennel
Fennel has a long history of use dating back to ancient times. The ancient Egyptians, Greeks, and Romans all used fennel for culinary and medicinal purposes. The ancient Greeks believed that fennel was a symbol of longevity and strength and it was dedicated to the Greek god Apollo. It was also thought to have many medicinal properties and was used to treat a variety of ailments such as indigestion, respiratory problems, and even snakebites.
Fennel was also considered to be a sacred herb in ancient times and was often used in religious rituals. In ancient Rome, fennel was used to ward off evil spirits and was thought to have protective properties.
Fennel was also used in medieval times as a flavoring for meats, fish, and other dishes. It was also believed to have many health benefits and was often used in tonics and elixirs.
Fennel was also introduced to America by the early settlers and has been used for culinary and medicinal purposes in North America ever since. Today, fennel is widely used in cooking and is a popular ingredient in many dishes around the world. It’s also still used in traditional medicine in some cultures.
How to Propagate Fennel
Fennel can be propagated through seeds or divisions. Both methods are relatively easy and can be done in the spring or fall.
Propagating Fennel from Seeds:
- Start by filling a seed tray or pots with seed compost and water it well.
- Sow the fennel seeds on the surface of the compost, leaving about 1/4 inch of space between each seed.
- Cover the seeds with a thin layer of compost or vermiculite.
- Place the tray or pots in a propagator or cover with a plastic bag and place it in a warm place (around 21°C) until germination, which usually takes about 7-14 days.
- Once the seedlings have germinated, remove the plastic bag and place the tray or pots in a sunny position, such as a windowsill.
- Once the seedlings are large enough to handle, transplant them into individual pots and grow them on until they are big enough to plant out.
Propagating Fennel from Divisions:
- Start by selecting a healthy fennel plant that is at least 2 years old.
- In the early spring or fall, dig up the entire plant with a garden fork.
- Carefully divide the rootball into smaller sections, making sure each section has a good number of roots.
- Plant each section in a new location, making sure to plant it at the same depth as it was previously growing.
- Water the newly planted divisions well and keep the soil consistently moist until they are established.
It’s important to note that fennel is a biennial plant and will only produce seeds in its second year, so if you want to save the seed, you’ll need to let the plants go to seed, and not harvest them. Also, when planting fennel in your garden, it’s best to plant them in a location where they will receive full sun exposure and well-draining soil.
How to Grow Fennel
Growing fennel is relatively easy and can be done in the garden or in containers. Here’s what you need to do to grow your very own fennel plants:
- Choose the Right Location: Fennel prefers full sun and well-drained soil. If your soil is heavy or poorly drained, consider raised beds or planting in containers.
- Prepare the Soil: Fennel prefers a slightly alkaline soil with a pH of 6.5 to 7.0. If your soil is too acidic, you can add lime to raise the pH.
- Planting: Fennel can be planted in the garden from seed or by transplanting seedlings. Plant the seeds about 1/4 inch deep, about 6 inches apart.
- Watering: Fennel requires consistent moisture, especially when the bulbs are forming. Water deeply once a week, or more often in hot, dry weather.
- Fertilizing: Fertilize your fennel plants with a balanced fertilizer every 4-6 weeks during the growing season.
- Harvesting: Your fennel bulbs are ready to be harvested once they reach a size of about 2-3 inches in diameter. Cut the bulb off at soil level and leave the stalks and leaves to continue growing. Fennel seeds can be harvested when they turn brown, dry them and store them in an airtight container.
By following these steps, you should be able to grow a healthy crop of fennel. Remember to be patient as it takes about 90-120 days for the bulb to mature, and to check for pests and diseases regularly.
Caring for Fennel
When growing and caring for fennel, there are several factors you’ll need to consider. Here are some tips for maintaining your fennel plants:
- Watering: As mentioned earlier, fennel needs consistent moisture. Water your fennel plants deeply at least once a week, or more often in hot, dry weather.
- Fertilizing: Fennel will benefit from a balanced fertilizer every 4-6 weeks during the growing season.
- Pest and Disease Control: Fennel is generally resistant to pests and diseases. However, watch out for aphids and spider mites, which can be controlled with insecticidal soap or neem oil.
- Mulching: Mulch around the base of the fennel plants to help retain moisture and suppress weeds.
- Staking: If you’re growing taller varieties of fennel, you may need to stake the plants to prevent them from falling over.
- Thin out seedlings: When seedlings have developed their first true leaves, thin them out so that they are about 6 inches apart.
- Pruning: Regular pruning can help to promote bushier growth and encourage larger bulbs.
- Harvesting: Fennel bulbs can be harvested when they reach a size of about 2-3 inches in diameter. Fennel seeds can be harvested when they turn brown.
- Companion planting: Companion planting can be very beneficial for fennel, planting it near dill, tomatoes, and brassicas, but avoid planting it near coriander and dill as they are known to inhibit each other’s growth.
- Rotate the crop: Rotating your fennel crop every year helps to prevent pests and diseases from building up in the soil.
By following these tips, you should be able to keep your fennel plants healthy and productive. Remember to be vigilant for pests and diseases, and to keep an eye on the weather, adjusting your watering and fertilizing as needed.
