NOTE: The terms Blue Atlas cedar and Cedrus atlantica are identical in this text; in reality, Cedrus atlantica is Blue Atlas cedar’s biological word.
If you are looking for a unique, eye-catching tree to grab attention in your landscape, consider planting a blue Atlas cedar. The needled evergreen, native to the Atlas Mountains in northern Africa, is covered with powdery whorls of blue needles and only produces a few small cones in the springtime. As it grows, it can be shaped into cone, oval, cylinder, or “weeping” shapes.
Why does my Cedrus atlantica roots have rot?
Root rot on your Blue Atlas cedar (Cedrus atlantica) can be dangerous if left untreated. In order to keep your plant alive, we strongly suggest that you follow our advice if the signs start to show: blackened and mushy roots.
Why does my Blue Atlas cedar have gray mold spots?
A particular fungus known as gray mold spots spreads quickly and frequently damages flowers. This fungus is probably to blame if you see any brown (or gray) spots. If you disregard these warning signs, your plant could die.
The solution is quite logical when you know the cause of the problem. Most of the time, it is due to overwater of the Cedrus atlantica. We advise you to remove the infected parts of the plant, cut off the infected roots and leaves, then repot your plant using sterile potting soil and a clean pot.
Why does my Blue Atlas cedar 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 Blue Atlas cedar, this kind of illness is among the most distressing.
Why are my Blue Atlas cedar 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 signs of yellowing caused by the many deficiencies on the Cedrus atlantica in question:
- 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.
- Yellowing between leaf veins is another sign of iron shortage, but young leaves on plant tops and branch tips are initially affected.
- Sulfur shortage first affects the youngest leaves, turning them entirely yellow.
- 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.
- Nitrogen deficiency shows up as a general yellowing. Older, inner leaves turn yellow first. As it progresses, yellowing moves outward, eventually reaching young leaves, too.
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 Blue Atlas cedar sunburned?
You can easily tell if your Blue Atlas cedar (your Cedrus atlantica) has a sunburn. In this case, your plant will change color, starting to turn yellow or white, much like it does on us.
The leaves of your Blue Atlas cedar can also change color in case it gets too much water or not enough light, as we saw above.
The bottom of the yellow leaves with a shaded area closer to the base can be examined to determine if they have been sunburned. If this part remains greener, the yellow leaf is most likely sunburned and not something else.
Why are my Blue Atlas cedar 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 Cedrus atlantica in direct sunlight?
No! Don’t leave your Cedrus atlantica (or Blue Atlas cedar) in the sun if it displays the symptoms mentioned above; that’s why it’s in such a bad situation.
As stated in the paragraph above, the cure is straightforward: simply position your plant’s Blue Atlas cedar 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 Cedrus atlantica leaves drooping or wilting ?
This typically occurs when your Cedrus atlantica gets dehydrated. Large plants are more at risk since they naturally require more water than smaller plants.
You may quickly determine if your Cedrus atlantica plant needs water by under-weighing its pot; if it seems light, the soil and roots are probably fairly dry and require water.
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 Blue Atlas cedar right away after a dry time because you think 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 Cedrus atlantica
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 Cedrus atlantica.
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 Cedrus atlantica 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 Cedrus atlantica near a source of hot (or cold) air such as A/C units, radiators or the like.
Keep your Blue Atlas cedar 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.
This would be a true journey into hell for your Blue Atlas cedar and would also satisfy the pests.
To remove the dust, gently rub the plant’s leaves with a microfiber cloth. Dust can be removed more easily with a damp cloth, but stay away from corrosive substances like rubbing alcohol!
Keep drainage in mind
If you tend to overwater, you need to pay attention to your drainage, and we advise choosing a saucer and a pot with drainage holes if they are not already there.
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.
