NOTE: Fennel may be referred to as Foeniculumvulgare in this article, in fact, those are the same plants, Foeniculumvulgare is the botanical name for Fennel.
For its ornamental value, fennel is a perennial herb grown both for and against it. Its feathery, branching, aromatic, yellow-green foliage and tall stature can be attractive as border plantings, in cottage gardens, and more. It is a good choice for butterfly gardens, as swallowtail caterpillars use it as a food source and pupal site.
The plant has small yellow flowers in the summertime, followed by aromatic seeds that can be Harvested along with the foliage. It has the same flavor as anise or Licorice. Fennel has a fast growth rate and is usually planted in the spring.
Why does my Foeniculumvulgare roots have rot?
If left untreated, root rot on your Fennel (Foeniculumvulgare) can be fatal. For this reason, if the symptoms appear, we highly advise that you adhere to our recommendations to keep your plant alive: Blackened and softened roots.
Why does my Fennel have gray mold spots?
Gray mold spots are a specific fungus that regularly harms flowers and spreads swiftly. If you notice any brown (or gray) spots, this fungus is probably to cause. You risk your plant dying if you ignore these warning indications.
When you understand the root of the issue, the solution makes perfect sense. The majority of the time, it is caused by the Foeniculumvulgare being overwatered. We urge you to cut off the infected roots and leaves, remove the affected sections of the plant, and then repot your plant in a fresh container with sterile potting soil.
Why does my Fennel have leaf spots?
If your plants exhibit symptoms like rapid color changes in the leaves or leaves that wilt or droop, we give you all the information you need to recognize them and rescue your plants. For owners of Fennel, this kind of illness is among the most distressing.
Why are my Fennel leaves turning yellow?
In the world of horticulture, yellowing leaves are undoubtedly the most common problem. The two main causes of this problem are overwatering and a lack of nutrition.
Reduce your watering frequency when you fear your plants are being overwatered, and follow these steps to determine whether they may be lacking in nutrients:
Here are some signs of yellowing caused by the many deficiencies on the Foeniculumvulgare in question:
- Yellow patches between leaf veins on elder leaves are the first sign of magnesium shortage. Veins continue to be green while the leaf’s core turns yellow. The leaf’s edges yellow last.
- Iron deficiency also shows as yellowing between leaf veins, but it hits young leaves on plant tops and branch tips first.
- Sulfur deficiency starts with the newest leaves, turning them yellow throughout.
- Insufficient potassium causes the leaf edges to turn brilliant yellow while the interior of the leaf stays green. Older leaves show the symptoms initially, and the leaf edges quickly darken.
- A broad yellowing indicates a nitrogen deficiency. Yellowing starts with older, inner leaves. Yellowing spreads as it advances, eventually touching new leaves as well.
According to the symptoms mentioned above, you just have to act accordingly. You can reduce your watering frequency, or fix a deficiency in Potassium, or Nitrogen, for that, you just have to buy a special soil for your deficiency, a consultant in a gardening store will know perfectly well how to inform you.
Is my Fennel sunburned?
It is quite easy to find out if your Fennel (Foeniculumvulgare) has been burned by the sun. Just like on us, your plant will change color in this case, it will start to turn yellow or white.
The leaves of your Fennel can also change color in case it gets too much water or not enough light, as we saw above.
However, there is a way to tell if it is sunburn; look at the bottom of the yellow leaves, the ones that have a shaded area closer to the root, if this area stays greener, it is probably sunburned, not something else.
Why are my Fennel leaves turning brown?
Most of the time, leaves of a Fennel that turn brown is a sign that your plant has been sunburned, it has probably been exposed to too much direct sunlight. Don’t panic, your plant probably won’t die from this, but its growth will take a hit.
Should I leave my Foeniculumvulgare in direct sunlight?
No! If your Foeniculumvulgare (or Fennel) has the symptoms described above, don’t leave it in direct sunlight, that’s the reason why your Fennel is in such a state!
As stated in the paragraph above, the cure is straightforward: simply position your plant’s Fennel so that it is out of direct sunlight. With proper watering and this method, your plant should quickly come back to life.
Why are my Foeniculumvulgare leaves drooping or wilting ?
When you become dehydrated, this usually happens. Large plants are more vulnerable since they need more water on a regular basis than smaller plants.
Whether your Foeniculumvulgare plant’s pot appears light, the soil and roots are likely fairly dry and need water, so you can readily tell if it needs to be hydrated.
If the soil in your plant’s pot is completely dry, you will need to start by moistening it so that the roots will also benefit from the water. A common mistake is to drown the Fennel right after a dry period thinking that it needs a lot of water.
This is the case, but giving too much water at once is the best way to finish it off, you should actually water the soil normally, resuming a quiet watering rhythm.
Caring Tips for Foeniculumvulgare
Water is essential to the survival of your plant, however, it is important to balance the rate of watering. As we explained above, overwatering could have fatal consequences for your Foeniculumvulgare.
Touching the soil will let you know whether your plant needs water or not; if it still feels damp, it’s generally best to wait a few more days.
Always keep temperatures stable
It is also a good idea to keep your Foeniculumvulgare at a stable temperature (especially if it is kept indoors!). At GreenShack, we generally recommend staying in the 65 and 85 degrees F range. Of course, do not place your Foeniculumvulgare near a source of hot (or cold) air such as A/C units, radiators or the like.
Keep your Fennel Dust-Free
This one concerns indoor plants, just like on your furniture, dust is also deposited on the leaves of your indoor plants, the problem is that it can prevent them from receiving the necessary light, this would slow down (or even stop) the photosynthesis process, and eventually, they would lose their colors.
This would be a true journey into hell for your Fennel and would also satisfy the pests.
Take a microfiber cloth and gently massage the plant’s leaves to get rid of the dust. Use a damp cloth to make dust removal easier, but avoid using corrosive materials like rubbing alcohol!
Keep drainage in mind
If you have a tendency to overwater, you need to keep an eye on your drainage, we advise you to opt for a pot with drainage holes if it is not already the case and a saucer.
You can add volcanic rocks (or any other pebbles with holes) to the bottom of your pot in the interim if your pots don’t already have holes in them. This will help to form a channel so that the water doesn’t pool there for too long (preventing the rot of the roots!).
