Stromanthe Triostar Care & Growing Guide

1. Light Requirement

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.

2. Water

The soil of this plant should be kept moist at all times. It is important that you use distilled or filled water. These plants tend to droop slightly when they are in need of water. If the soil feels very dry, you should definitely water it.

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.

3. Climate

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.

4. Soil

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.

6. Repotting

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.

8. Flowers

It is very uncommon for the Stromanthe Triostar to produce flowers. The flowers on this plant will be white with bright red bracts. When this plant does bloom, it is typically somewhere between late winter and early spring. While you might not get this plant to flower, its red foliage is quite beautiful and impressive.

9. Trimming

The only trimming that you’ll really need to do with these plants is removing any withered leaves. You’ll also want to cut off any leaves that appear brown or yellow, as they are most likely infected.

Trimming this plant is also necessary for maintaining its shape. You won’t have to do this very often, but it is important to stay on top of it.
