Bay laurel: Diseases and Remedies (Laurus nobilis)

NOTE: In this article, Bay laurel and Laurus nobilis may be used interchangeably; in fact, Laurus nobilis is the botanical name for Bay laurel.

The leaves of bay laurel are best known for their use as a kitchen seasoning, but bay laurel is actually an evergreen shrub or tree native to the Mediterranean area. It has large, pointed leaves that are glossy green in color and have a leathery texture.

A dense green pyramidal canopy is supported by a medium- to large-sized tree with multiple stems. This slow-growing plant is often seen as a shrub or container plant trimmed into a dense green mass, because it willingly accepts heavy pruning.

Why are my Bay laurel leaves turning yellow?

This is probably the most common problem in the gardening world, yellowing leaves. There are 2 main reasons for this phenomenon, overwatering, or a lack of nutrients.

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 indicators of yellowing on the Laurus nobilis brought on by its numerous flaws:

  • Magnesium deficiency starts as yellow patches between leaf veins on older leaves. Veins stay green as yellow moves from the leaf center out. Leaf edges turn yellow last.
  • Another indicator of iron deficiency is yellowing between leaf veins, but young leaves on plant tops and branch tips are first affected.
  • 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 lack of nitrogen is indicated by a widespread yellowing. Older, inner leaves are the first to yellow. As the yellowing progresses, it eventually touches young leaves as well.

Our Solution

You only need to respond to the signs mentioned above. A gardening store expert will be able to provide you advice on how to purchase a specific soil to treat a potassium or nitrogen deficiency. Additionally, you can reduce how often you water your plants.

Is my Bay laurel sunburned?

It is quite easy to find out if your Bay laurel (Laurus nobilis) 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.

Sunburned

As we saw above, the leaves of your Bay laurel can also change color if it receives too much water or insufficient light.

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 Bay laurel leaves turning brown?

A plant’s browning leaves are typically a symptom that it has been sunburned and has been exposed to excessive amounts of direct sunlight. Don’t worry; your plant probably won’t perish as a result, but its growth will be negatively impacted.

Should I leave my Laurus nobilis in direct sunlight?

No! If your Laurus nobilis (or Bay laurel) has the symptoms described above, don’t leave it in direct sunlight, that’s the reason why your Bay laurel is in such a state!

Our Solution

As stated in the paragraph above, the cure is straightforward: simply position your plant’s Bay laurel 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 Laurus nobilis leaves drooping or wilting ?

In most cases, this happens when your Laurus nobilis lacks water. This is especially the case for large plants, naturally they need more water than others.

Drooping

You may quickly determine if your Laurus nobilis plant needs water by under-weighing its pot; if it seems light, the soil and roots are probably fairly dry and require water.

Our Solution

If the soil in the container is completely dry, you must first moisten it to guarantee that your plant’s roots absorb the benefits of the water. One common mistake is to drown the Bay laurel right away after a dry time because you think it needs a lot of water.

This is true, but the easiest way to end it is to give too much water at once. Instead, you should water the soil properly, returning to a peaceful watering rhythm.

Caring Tips for Laurus nobilis

Water Occasionally

Your plant needs water to survive, but it’s crucial to balance the amount and timing of watering. As we previously mentioned, overwatering could be catastrophic for your Laurus nobilis.

The best way to know if your plant needs water or not is to touch the soil, if you feel it is still wet, it is probably a good idea to wait a few more days.

Always keep temperatures stable

It’s also a good idea to keep your Laurus nobilis at a constant temperature, especially if it’s kept indoors. In general, at GreenShack, we suggest booking a temperature between 65 and 85 degrees F. Of course, keep your Laurus nobilis away from radiators, air conditioners, and other sources of hot or cold air.

Keep your Bay laurel Dust-Free

This one is about houseplants. Your indoor plants’ leaves get dusty just like your furniture does. The problem is that this might prevent photosynthesis from beginning, which would result in the plants gradually losing their color.

For your Bay laurel, this would be a true descent into hell, and it would also appease the pests.

To remove the dust from the leaves of your plant, take a microfiber cloth and gently rub the leaves. You can wet the cloth to make it easier to remove the dust, but never use corrosive products (such as rubbing alcohol!)

Keep drainage in mind

If you have a tendency to overwater, you should be mindful of your drainage, and if they don’t already have them, we suggest selecting a saucer and a pot with drainage holes.

If your pots don’t already have holes in them, you can add volcanic rocks (or any other pebbles with holes) to the bottom of your pot in the meantime. This will assist in creating a channel and keep the water from pooling there for an extended period of time, protecting the roots from decay.
