These plants need to be kept in bright but indirect light to grow and stay healthy. Even a moderate amount of direct sunlight can burn its leaves.
If you are keeping this plant outside, find a shady spot for it. If you are keeping it inside, you should place it three or four feet from a curtained window that gets direct sunlight.

The plant’s top inch of soil should be dry before you water it again. You will be able to determine this by simply sticking your finger down into it. Avoid using tap water, as it tends to contain chlorine and other things that can turn the leaves brown.
Stromanthe Triostar plants can be grown in USDA hardiness zones 10 through 12. They can be traced back to Brazil and the surrounding areas. This means that these plants do well in climates that are very humid.
Make sure that you use a potting mix that drains well. You should use a 50/50 combination of perlite and potting mix. This will provide your plant with the best chances of growing healthy without any issues.
While moisture is important for this plant’s soil, you don’t want it to get soggy. This can lead to root rot, which is difficult to reverse.
You should also fertilize your plant every two to three weeks with a balanced fertilizer that is very dilute. This too is crucial when it comes to promoting healthy and normal growth.
These plants need to be kept within a temperature range of 65 to 80 degrees Fahrenheit. You should take them inside when the weather starts getting cooler. They do not tolerate cold very well at all.
Keep in mind that your plants will thrive in a high-humidity environment. If you don’t live in an area that is very humid, you should still be able to grow them. You will, however, need to spray your plants often to make up for the lack of humidity.
Unlike many other plants, the Stromanthe Triostar actually does well when it is rootbound. You won’t have to repot this plant more than once every three years or so.
