NOTE: In this article, Persian shield and Strobilanthes dyerianus may be used interchangeably; in fact, Strobilanthes dyerianus is the botanical name for Persian shield.
It’s easy to understand how “Persian shield” was used. The leaves have the appearance of little pointed armor shields ready for battle, with a flashy, purple iridescence and silvery metallic sheen. The plant is called “Persian,” but it is actually native to the country of Myanmar. In hot climates, it is an evergreen subshrub.
In cooler climates, it is grown as an annual plant, and is also popular as a houseplant because it blooms during the winter. The vibrant purple color fades with age, and both outdoor and indoor potted plants are often discarded after a few years.
Why does my Strobilanthes dyerianus roots have rot?
Root rot on your Persian shield (Strobilanthes dyerianus) can be fatal if not treated with care. For this reason, we strongly recommend that you follow our guide to keep your plant alive if the symptoms occur: Root soft and blackened.
Why does my Persian shield 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 Strobilanthes dyerianus. 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 Persian shield 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 Persian shield owners.
Why are my Persian shield 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.
Whether you think your plants are getting too much water, cut back on how often you water them, and take the following measures to see if they might be nutritionally deficient:
Here are some signs of yellowing caused by the many deficiencies on the Strobilanthes dyerianus 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.
- 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.
- 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 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 Persian shield sunburned?
You can easily tell if your Persian shield (your Strobilanthes dyerianus) has a sunburn. In this case, your plant will change color, starting to turn yellow or white, much like it does on us.
As we saw above, the leaves of your Persian shield can also change color if it receives too much water or insufficient light.
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 Persian shield 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 Strobilanthes dyerianus in direct sunlight?
No! Don’t leave your Strobilanthes dyerianus (or Persian shield) in the sun if it displays the symptoms mentioned above; that’s why it’s in such a bad situation.
The remedy, as said in the paragraph above, is simple: just move your plant’s Persian shield out of direct sunlight. Your plant should swiftly re-grow with this strategy and appropriate watering.
Why are my Strobilanthes dyerianus 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 Strobilanthes dyerianus 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 Persian shield 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 Strobilanthes dyerianus
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
It’s also a good idea to keep your Strobilanthes dyerianus 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 Strobilanthes dyerianus away from radiators, air conditioners, and other sources of hot or cold air.
Keep your Persian shield 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 be a true journey into hell for your Persian shield and would also satisfy 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.
