NOTE: The terms Blackhaw viburnum and Viburnum prunifolium are identical in this text; in reality, Viburnum prunifolium is Blackhaw viburnum’s biological word.
Blackhaw viburnum is a shrub with an upright growth habit that grows as wide as it is tall. It can be trained to grow as a small tree with a single trunk. Its bark is brown, and it has glossy dark green leaves that are about 4 inches long.
In the late spring, clusters of small white flowers appear, followed by yellow berries that mature to a blue- black color. Humans can eat fruits that birds and other wildlife like. The leaves turn to shades of red and purple during the fall. The best time to plant this shrub is in the early spring or fall.

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.

Here are some indicators of yellowing on the Viburnum prunifolium brought on by its numerous flaws:
- The first symptom of a magnesium deficiency is yellow patches between leaf veins on elder leaves. The leaf’s core turns yellow while the veins stay green. The edges of the leaf yellow last.
- Yellowing between leaf veins is another sign of iron shortage, but young leaves on plant tops and branch tips are initially 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 broad yellowing indicates a nitrogen deficiency. Yellowing starts with older, inner leaves. Yellowing spreads as it advances, eventually touching new 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 Blackhaw viburnum sunburned?
It is simple to determine whether your Blackhaw viburnum (your Viburnum prunifolium) has sunburn. Your plant will change color in this instance, beginning to turn yellow or white, much like it does on us.
As we saw above, if your Blackhaw viburnum receives too much water or not enough light, the leaves may also change color.
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 Blackhaw viburnum leaves turning brown?
The classic sign that a plant has been overexposed to direct sunlight and sunburned is the development of browning leaves. Rest assured that while this may probably save your plant from dying, it will adversely affect its growth.
Should I leave my Viburnum prunifolium in direct sunlight?
No! If your Viburnum prunifolium (or Blackhaw viburnum) has the symptoms described above, don’t leave it in direct sunlight, that’s the reason why your Blackhaw viburnum is in such a state!
The remedy, as said in the paragraph above, is simple: just move your plant’s Blackhaw viburnum out of direct sunlight. Your plant should swiftly re-grow with this strategy and appropriate watering.
Why are my Viburnum prunifolium leaves drooping or wilting ?
In most cases, this happens when your Viburnum prunifolium lacks water. This is especially the case for large plants, naturally they need more water than others.
An easy way to know if your Viburnum prunifolium 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 Blackhaw viburnum 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 Viburnum prunifolium
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 Viburnum prunifolium.
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 Viburnum prunifolium 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 Viburnum prunifolium away from radiators, air conditioners, and other sources of hot or cold air.
Keep your Blackhaw viburnum 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 Blackhaw viburnum, this would be a true descent into hell, and it would also appease 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.
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.
