Caring for Your Fennel Plant

Fennel is a low-maintenance plant that can be planted next to dill, cucumber, and nasturtium. When planting fennel, avoid planting it next to tomato, beans, coriander, and kohlrabi. Fennel can be harvested from the bulb and fronds of the plant.

Watering and Feeding

Water fennel plants every two days for the first month after planting. Apply a mild dose of fertilizer every three weeks to help them grow strong. Fennel needs frequent watering in the beginning of its life, but becomes drought-tolerant later in the year.


Pruning is the process of removing parts of a plant in order to improve its shape, health, or productivity. There are different reasons why you might want to prune a plant, but one of the most common reasons is to encourage new growth and blooms. Deadheading is a specific type of pruning that refers to the removal of flowers from plants in order to prevent them from self-seeding. This is necessary for plants that you want to harvest seeds from, as well as for plants that you don’t want to overtake an area with their seedlings. Fennel is a plant that can re-seed itself, so it’s important to remove dead stems when they appear. Although fennel can be invasive if not regularly maintained, it is not as invasive as some other plants.


Fennel is a plant that propagates from seeds. The seeds can be planted directly in the ground, and will grow into new plants. However, it is also possible to propagate fennel from root cuttings. This is more challenging, as the root cuttings need to be taken from a healthy plant and placed in ideal conditions in order to grow. Fennel has long, fragile taproots, so it is important not to disturb the plant once it has been propagated. Additionally, the seeds of fennel are one and the same – they will produce a new plant regardless of whether they are planted indoors or outdoors.

What Not To Grow With Fennel And Why

Caraway And Fennel

Caraway and fennel are two plants that have a unique relationship. Caraway seeds will not germinate if they are planted near fennel, and fennel will not produce seeds if it is planted near coriander. This is because caraway seeds produce a chemical that inhibits the germination of fennel, and fennel produces a chemical that inhibits the germination of coriander.

Coriander(Cilantro) And Fennel

Coriander and Fennel are two herbs that are commonly grown together. However, both plants have some unique allelopathic properties that should be taken into consideration when planting them. Fennel is allelopathic to all plants, meaning it produces a substance that inhibits the growth of other plants. This includes coriander. Additionally, coriander and fennel inhibit each other’s growth- if planted near each other, neither plant will reach its full potential. Fennel will not produce seeds if planted near coriander.

When it comes to coriander and fennel, it is important to be aware that they cross-pollinate. This means that if you have both plants in your garden, you will end up with a horrible-tasting plant. Additionally, coriander can help suppress the growth of fennel. So, if you’re trying to get rid of fennel in your garden, planting coriander next to it will help.

Beans And Fennel

Beans and fennel are two plants that are commonly grown in gardens. However, there are a few things to be aware of when planting these two plants together. Firstly, beans are liable to suffer from disturbed growth if they are planted near fennel. Secondly, don’t plant fennel next to tomato and beans – the proximity of these plants will inhibit each other’s growth. Finally, don’t plant fennel next to coriander, kohlrabi, and wormwood – these plants do not pair well with fennel.

Kohlrabi And Fennel

Kohlrabi is a plant that suffers from disturbed growth when it is grown near fennel. It is not entirely clear why this happens, but it seems to be related to the scent of the fennel plant. If you are planning on growing kohlrabi, it is best to avoid planting it near fennel. However, there are a number of other plants that you can grow next to kohlrabi, including dill, cucumber, and nasturtium.

It is important to be aware of its needs and quirks in order to get the most out of this plant. For instance, fennel is a plant that gives and takes offense easily. It is important to be mindful of its surroundings and to avoid planting it near other plants that may compete for its resources or cause it harm.

Tomatoes And Fennel

Tomatoes and fennel are related plants, but they do not get along well together. Fennel will blight the growth of tomatoes, and as does parsley with some types of tomatoes (more research is needed on this subject). Fennel is related to parsley, but not as much as beans and tomatoes. If you want to grow tomatoes from tomatoes, you should plant them in a different part of your garden than where you are planting fennel.

Fennel is a cool-season crop that can be planted early in the spring or late in the fall. It can also be grown throughout the summer in areas with cooler temperatures.

Fennel is a plant that is related to carrots and parsley. It has a long stalk with feathery leaves on top. It is often used as an herb in cooking.

Aubergines(Egg plants) And Fennel

Aubergines and Florence fennel should not be grown in the same area as they can negatively affect the growth of each other. Fennel bulb is more tender and sweet at harvest and seed stalks can be removed for increased production of stems and bulbs. Self-seeding will increase production if left unattended.

Wormwood And Fennel

Wormwood is a plant that is known for its ability to stop the growth of other plants. It has been used for this purpose for centuries and is still a popular choice today. Fennel, on the other hand, should not be planted near any other crops. This is because it emits a chemical that has been identified as absinthin from both the roots and from leaves washed in rainwater. This chemical can be very harmful to nearby plants.

growing fennel from bulb

Fennel is a vegetable that takes work and attention. It’s well worth the effort to grow and can be eaten raw or cooked. One downside to growing fennel is that it will bolt (flower too quickly).
