NOTE: In this article, Korean spicebush and Viburnum carlesii may be used interchangeably; in fact, Viburnum carlesii is the botanical name for Korean spicebush.
The Korean spice viburnum is a shrub with fragrant flowers. It’s a great specimen plant for spring blossoms because it thrives in USDA plant hardiness zones 4 through 7. The flowers start as pink buds and change to white blooms with a hint of the early pink color. The white flower clusters are very fragrant and nicely rounded.
Why does my Viburnum carlesii roots have rot?
Root rot on your Korean spicebush (Viburnum carlesii) 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 Korean spicebush 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 Viburnum carlesii. 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 Korean spicebush have leaf spots?
We provide you with all the information you need to identify and save your plants if they display signs like leaves that suddenly change color or wilt/droop. This sort of sickness is one of the most aggravating for Korean spicebush owners.
Why are my Korean spicebush leaves turning yellow?
Yellowing leaves are arguably the most prevalent issue in the gardening world. Overwatering or a lack of nutrients are the 2 main causes of this issue.
When it’s overwatering, simply reduce your watering frequency, and if you think it’s a nutrient deficiency, here’s how to check it:
Here are some signs of yellowing caused by the many deficiencies on the Viburnum carlesii 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.
- Yellowing between leaf veins is another sign of iron shortage, but young leaves on plant tops and branch tips are initially affected.
- Sulfur deficiency starts with the newest leaves, turning them yellow throughout.
- Leaf edges turning bright yellow but inside leaf remaining green are signs of potassium insufficiency. The symptoms first appear on older leaves, and the leaf edges quickly become dark.
- 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.
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 Korean spicebush sunburned?
It is quite easy to find out if your Korean spicebush (Viburnum carlesii) 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.
As we saw above, if your Korean spicebush receives too much water or not enough light, the leaves may also change color.
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 Korean spicebush 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 Viburnum carlesii in direct sunlight?
No! If your Viburnum carlesii (or Korean spicebush) has the symptoms described above, don’t leave it in direct sunlight, that’s the reason why your Korean spicebush is in such a state!
The remedy, as said in the paragraph above, is simple: just move your plant’s Korean spicebush out of direct sunlight. Your plant should swiftly re-grow with this strategy and appropriate watering.
Why are my Viburnum carlesii 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.
An easy way to know if your Viburnum carlesii is lacking water is to under-weigh its pot, if it looks light, it means that the soil and the roots are probably quite dry, and therefore need 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 Korean spicebush 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 Viburnum carlesii
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 Viburnum carlesii.
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
Maintaining a consistent temperature for your Viburnum carlesii is also a good idea, especially if it is kept indoors. At GreenShack, we typically advise reserving a temperature between 65 and 85 degrees F. Of course, avoid positioning your Viburnum carlesii close to air conditioners, radiators, or other sources of hot or cold air.
Keep your Korean spicebush 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.
For your Korean spicebush, 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 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!).
