Don’t worry, I’ll answer that question for you.

First, growing fennel is a great way to add an aromatic addition to your kitchen. 

You can plant seeds directly in the ground, or scatter them among your garden beds

The seedlings will grow quickly and need little protection once established. To keep them from bolting, store seeds in an airtight jar or paper bag. 

Fennel needs well-draining soil with a lot of organic matter.

If you do not grow a garden bed, consider using composted soil that is high in organic matter.

You can harvest Fennel after 90 days of planting the bulbs. When the plant has reached its prime, the leaves can be harvested quickly. Harvest the leaves gradually (a few at a time so you don’t kill the plant), and you can harvest Fennel bulb when it grows to 4 inches in diameter (about the size of a tennis ball).

How Big Does Fennel Get?

Fennel grows to a height of 2 to 3 feet but is usually harvested when it is 4 inches across. 

The bulbs do not produce seeds, so harvest them ideally when they reach 4 inches in diameter (i.e., across). The plant will self-sow and will eventually regrow.

The plant has its origins in the Mediterranean region of Europe and has been used for centuries as a spice and culinary staple. Many cultures have cultivated fennel as a way to hide the inferior quality of food.

Fennel Grows Best in Well-drained Moist Soil

To ensure the best quality bulbs, Fennel needs moist soil that drains well. In addition to the soil, the fennel bulb needs to be slightly acidic. 

The ideal pH level for fennel is between 5.5 and 7.0. If the soil is too acidic, it may produce flowerless fennel. If you want to protect your fronds from rotting, use lime or fertilizer that has the right N-P-K numbers.

To get healthy fennel bulbs, start by growing them in your garden.

You should break up compacted soil with a tiller before planting. The soil should also have plenty of organic matter, which is important for fennel to grow. If you plan to use a container, place the bag in a place with good air circulation.

Grow Fennel Bulb in Full Sun (Preferably)

For the best results, fennel should be grown in full sun. It is important to break up compacted soil before planting fennel. It is also important to water frequently. 

However, you should not overwater the fennel plant, as this may cause it to die. Then, you can harvest the leaves whenever you like.

Plant seeds in a shallow dish. After the seeds have soaked, place them in a sunny location. They should sprout within a week. 

You should thin the plants to four inches when they are able to reach maturity. Once they have reached three to four inches, thin them and store them in a glass jar or paper seed packet. Once a crop has reached maturity, the fennel is ready for harvesting.

Fennel and Watering Requirements

Florence fennel | Plant Gardener

While it’s important to keep the fennel bulbs moist, these plants do not like to be overwatered, as they will rot the roots. The fennel bulb is the best part of the fennel plant.

The leaves are edible. Its leaves are the best source of nutrients and fiber.

If you grow fennel in a garden, it is best to plant the seeds in water. The fennel plant will need regular watering.

The seeds are perennial and will grow for years. They can grow up to six feet. You can plant them from seeds or use them in a variety of dishes. 

The fennel bulb is a great addition to the soups and stews you prepare in the kitchen.

Harvesting Fennel 

To harvest fennel, cut fennel stems and leaves at ground level to encourage new growth. You can then chop the fennel stalks and shoots to use later in the season. 

Remember to water the plants regularly, particularly if the weather is dry. It’s important not to crowd the fennel plant, as the seeds won’t be as healthy as those you harvest.

Fennel Will Mature a Month After Transplanting

After transplanting your fennel seeds, it will take about a month to reach maturity. It is best to plant them in spring or late summer so that they don’t have to endure the hot summer months. 

You can thin the fennel after they are three to four inches to harvest the bulbs. If you don’t have a garden, you can plant them in containers. They can be planted in the ground or in pots and should be spaced about 12 inches apart.

Replanting Your Bulbs

Once you have harvested your fennel plant, you can either replant it. If you’re planting in a windy location, you can stake the plants. 

This is essential since fennel has a long taproot and can easily be blown over. A stake should be at least 6 inches from the base of the stems to avoid damaging the roots. 

Staking can be done after the first few seeds have sprouted, so you need to watch for the growth of the clump.

Does Fennel Regrow After Cutting?

If you have a fennel plant in your garden, you may be wondering whether it will regrow after you cut it. 

You don’t need to worry about re-growing fennel, as its bulbs will continue to grow. All you need to do is remove the dead stems, cut the stems into quarters, and store them in the fridge for about five days. 

When it’s time to harvest, you can simply cut the whole bulb and place it in the sunshine.

As a perennial, fennel will bloom the second year after cutting it. Because it has a taproot, you can prune fennel after flowering to promote new growth.

However, you should never prune more than a third of the plant at one time. You can also try to plant fennel in raised beds to increase their water retention capabilities. When cutting fennel, be sure to keep it moist.

Mulch can help lock in moisture.
