NOTE: Japanese pagoda tree may be referred to as Styphnolobium japonicum in this article, in fact, those are the same plants, Styphnolobium japonicum is the botanical name for Japanese pagoda tree.
The Japanese pagoda tree (Styphnolobium japonicum) is a Chinese native and the only thing that will make you question it is the confusing name. A Japanese pagoda tree, also called Chinese scholar tree, is perfect if you live in an urban setting, are looking for a flowering shade tree, or are planning a Japanese garden.
The Japanese pagoda tree is a beautiful tree that you will want to add to your garden design if you have enough space and the patience to devote to the payoff that comes when it is ready to show off.
Why does my Styphnolobium japonicum roots have rot?
Root rot on your Japanese pagoda tree (Styphnolobium japonicum) 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 Japanese pagoda tree 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.
Our Solution
The answer is obvious once you recognize the cause of the problem. Most frequently, it results from the Styphnolobium japonicum being overwatered. We strongly advise you to remove the damaged plant parts, cut off the diseased roots and leaves, and then repot your plant in a new container with sterile potting soil.
Why does my Japanese pagoda tree 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 Japanese pagoda tree owners.
Why are my Japanese pagoda tree 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.
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 indicators of yellowing on the Styphnolobium japonicum brought on by its numerous flaws:
- 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 shortage first affects the youngest leaves, turning them entirely yellow.
- 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 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.
Our Solution
You only need to act in accordance with the symptoms listed above. You can address a potassium or nitrogen deficiency by buying a particular soil, and a gardening store consultant will be able to advise you on how to do that. Furthermore, you can also limit how frequently you water your plants.
Is my Japanese pagoda tree sunburned?
It is simple to determine whether your Japanese pagoda tree (your Styphnolobium japonicum) has sunburn. Your plant will change color in this instance, beginning to turn yellow or white, much like it does on us.
The leaves of your Japanese pagoda tree can also change color in case it gets too much water or not enough light, as we saw above.
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 Japanese pagoda tree 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 Styphnolobium japonicum in direct sunlight?
No! If your Styphnolobium japonicum (or Japanese pagoda tree) has the symptoms described above, don’t leave it in direct sunlight, that’s the reason why your Japanese pagoda tree is in such a state!
Our Solution
As explained in the paragraph above, the solution is simple, just place your Japanese pagoda tree in a place where the light does not reach it directly, in this way and with a correct watering, your plant should resume its life rather quickly.
Why are my Styphnolobium japonicum 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.
You may quickly determine if your Styphnolobium japonicum plant needs water by under-weighing its pot; if it seems light, the soil and roots are probably fairly dry and require water.
Our Solution
In order to ensure that the roots of your plant receive the water’s benefits, you must first moisten the soil in the container if it is absolutely dry. One common error is to immediately drown the Japanese pagoda tree after a dry period in the belief that it requires 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 Styphnolobium japonicum
Water Occasionally
Water is necessary for your plant to live, but timing and amount of watering must be balanced. Overwatering could have disastrous effects on your own name, as we already mentioned.
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
Maintaining a consistent temperature for your Styphnolobium japonicum 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 Styphnolobium japonicum close to air conditioners, radiators, or other sources of hot or cold air.
Keep your Japanese pagoda tree 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.
This would also make the pests happy, a real descent into hell for your Japanese pagoda tree.
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.
In the meantime, if you don’t have holes in your pots, you can add volcanic rocks (or any rocks with holes) at the bottom of your pot, this way it will create a channel so that the water doesn’t stay in your skin too much (to avoid that roots start to rot!)
