NOTE: The terms Stromanthe triostar and Stromanthe sanguinea are identical in this text; in reality, Stromanthe sanguinea is Stromanthe triostar’s biological word.
The triostar stromanthe is full of variegate foliage and has bright shades of pink. It can be grown outdoors in hot and humid climates, but it does best indoors and is more commonly grown as a house plant.
Why does my Stromanthe sanguinea roots have rot?
Root rot on your Stromanthe triostar (Stromanthe sanguinea) 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 Stromanthe triostar 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 Stromanthe sanguinea. 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 Stromanthe triostar have leaf spots?
This type of disease is one of the most frustrating for Stromanthe triostar 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 Stromanthe triostar 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.
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 Stromanthe sanguinea in question:
- 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.
- Yellowing between leaf veins is another sign of iron shortage, but young leaves on plant tops and branch tips are initially affected.
- 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.
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 Stromanthe triostar sunburned?
It is quite easy to find out if your Stromanthe triostar (Stromanthe sanguinea) has been burned by the sun. Just like on us, your plant will change color in this case, it will start to turn yellow or white.
As we saw above, the leaves of your Stromanthe triostar can also change color if it receives too much water or insufficient light.
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 Stromanthe triostar 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 Stromanthe sanguinea in direct sunlight?
No! Don’t leave your Stromanthe sanguinea (or Stromanthe triostar) 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 Stromanthe triostar out of direct sunlight. Your plant should swiftly re-grow with this strategy and appropriate watering.
Why are my Stromanthe sanguinea leaves drooping or wilting ?
This typically occurs when your Stromanthe sanguinea gets dehydrated. Large plants are more at risk since they naturally require more water than smaller plants.
An easy way to know if your Stromanthe sanguinea 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 Stromanthe triostar right away after a dry time because you think it needs a lot of water.
This is the case, but giving too much water at once is the best way to finish it off, you should actually water the soil normally, resuming a quiet watering rhythm.
Caring Tips for Stromanthe sanguinea
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 Stromanthe sanguinea.
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 is also a good idea to keep your Stromanthe sanguinea 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 Stromanthe sanguinea near a source of hot (or cold) air such as A/C units, radiators or the like.
Keep your Stromanthe triostar Dust-Free
This one concerns indoor plants, just like on your furniture, dust is also deposited on the leaves of your indoor plants, the problem is that it can prevent them from receiving the necessary light, this would slow down (or even stop) the photosynthesis process, and eventually, they would lose their colors.
This would also make the pests happy, a real descent into hell for your Stromanthe triostar.
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.
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!)
