NOTE: Boxwood may be referred to as Buxus spp. in this article, in fact, those are the same plants, Buxus spp. is the botanical name for Boxwood.
70 species of slow-growing broadleaf evergreens with small, rounded, and leathery leaves are in the Buxus genera. B. sempervirens and B. microphylla are the two species that are found in most of the garden forms. Most of the boxwood varieties used in modern landscaping are dwarf varieties, such as B. sempervirens ‘Suffruticosa’, a popular plant for hedges and topiaries.
The Korean is a dwarf variety of Buxus sinica. It is just 2 feet tall and has a slightly greater spread. These dwarf boxwood shrubs have a rounded, compact growth habit and are prized for their densely packed, light-green leaves.
Why does my Buxus spp. roots have rot?
If left untreated, root rot on your Boxwood (Buxus spp.) can be fatal. For this reason, if the symptoms appear, we highly advise that you adhere to our recommendations to keep your plant alive: Blackened and softened roots.
Why does my Boxwood have gray mold spots?
A particular fungus that frequently affects flowers and spreads quickly is known as gray mold spots. This fungus is most likely to blame if you see any brown (or gray) spots. Don’t ignore these signs because doing so could cause your plant to 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 Buxus spp.. 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 Boxwood 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 Boxwood, this kind of illness is among the most distressing.
Why are my Boxwood 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:
Each deficiency produces a different yellowing on the Buxus spp. in question, here’s how to spot them:
- 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.
- Iron deficiency also shows as yellowing between leaf veins, but it hits young leaves on plant tops and branch tips first.
- Sulfur deficiency starts with the newest leaves, turning them yellow throughout.
- Potassium deficiency shows itself when leaf edges turn bright yellow, but the inner leaf stays green. Older leaves show symptoms first, and leaf edges soon turn brown.
- 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 Boxwood sunburned?
It is simple to determine whether your Boxwood (your Buxus spp.) 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 Boxwood 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 Boxwood 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 Buxus spp. in direct sunlight?
No! If your Buxus spp. (or Boxwood) has the symptoms described above, don’t leave it in direct sunlight, that’s the reason why your Boxwood is in such a state!
The remedy, as said in the paragraph above, is simple: just move your plant’s Boxwood out of direct sunlight. Your plant should swiftly re-grow with this strategy and appropriate watering.
Why are my Buxus spp. leaves drooping or wilting ?
In most cases, this happens when your Buxus spp. lacks water. This is especially the case for large plants, naturally they need more water than others.
You may quickly determine if your Buxus spp. 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 Boxwood 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 Buxus spp.
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 Buxus spp..
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
Maintaining a consistent temperature for your Buxus spp. 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 Buxus spp. close to air conditioners, radiators, or other sources of hot or cold air.
Keep your Boxwood 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 Boxwood, 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.
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.
