NOTE: The terms Viburnum and Viburnumspp. are identical in this text; in reality, Viburnumspp. is Viburnum’s biological word.
One of the most popular landscape shrubs are viburnums. Most viburnum shrubs bloom from early spring through June, followed by attractive fruit and outstanding fall foliage. As shrubs or small trees, fast-growing viburnums can be grown.
Why does my Viburnumspp. roots have rot?
Root rot on your Viburnum (Viburnumspp.) 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 Viburnum have gray mold spots?
Gray mold spots are a type of fungus that is found a lot in flowers, and spreads quite rapidly. If you notice brown (or gray) spots, it is probably this fungus. Don’t ignore these symptoms, as they may end up killing your plant.
The solution is quite logical when you know the cause of the problem. Most of the time, it is due to overwater of the Viburnumspp.. 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 Viburnum have leaf spots?
This type of disease is one of the most frustrating for Viburnum owners, we give you all the leads to spot and save your plants that present symptoms such as leaves that suddenly change color, or wilt/droop.
Why are my Viburnum 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.
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 Viburnumspp. 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.
- Another indicator of iron deficiency is yellowing between leaf veins, but young leaves on plant tops and branch tips are first affected.
- The newest leaves are first affected by sulfur deficiency, rendering them completely yellow.
- 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.
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 Viburnum sunburned?
You can easily tell if your Viburnum (your Viburnumspp.) 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 Viburnum can also change color in case it gets too much water or not enough light, as we saw above.
To find out if the yellow leaves have been sunburned, look at the part of the bottom that is tinted closer to the base. The yellow leaf is probably burnt and not something else if this portion stays greener.
Why are my Viburnum leaves turning brown?
Most of the time, leaves of a Viburnum 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 Viburnumspp. in direct sunlight?
No! If your Viburnumspp. (or Viburnum) has the symptoms described above, don’t leave it in direct sunlight, that’s the reason why your Viburnum is in such a state!
The remedy, as said in the paragraph above, is simple: just move your plant’s Viburnum out of direct sunlight. Your plant should swiftly re-grow with this strategy and appropriate watering.
Why are my Viburnumspp. leaves drooping or wilting ?
This typically occurs when your Viburnumspp. gets dehydrated. Large plants are more at risk since they naturally require more water than smaller plants.
You may quickly determine if your Viburnumspp. 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 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 Viburnum right after a dry period thinking that 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 Viburnumspp.
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 Viburnumspp..
You can tell if your plant needs water by touching the soil; if it still feels damp, it’s usually preferable to wait a few more days.
Always keep temperatures stable
It is also a good idea to keep your Viburnumspp. 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 Viburnumspp. near a source of hot (or cold) air such as A/C units, radiators or the like.
Keep your Viburnum Dust-Free
This one relates to indoor plants. Just like your furniture, dust collects on the leaves of your indoor plants. The issue is that this can block the photosynthesis process from starting, which would cause the plants to gradually lose their color.
For your Viburnum, 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.
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!).
