Stromanthe Triostar Care Requirements

These plants are relatively easy to care for, However, they do have a few specific requirements that you need to meet to keep them healthy and happy.


The Stromanthe triostar prefers bright, indirect light. Placing your plant near an east- or west-facing window is ideal, as it will receive ample light without the harsh intensity of direct sunlight. Avoid placing your Stromanthe triostar in direct sunlight, as this can scorch its leaves.


The Stromanthe triostar thrives in moist soil but is not fond of soggy conditions. Allow the top inch of soil to dry out slightly between waterings.

You should also avoid using tap water, as it can contain chlorine and other chemicals that can harm the plant. Instead, use filtered or distilled water.


The Stromanthe triostar is native to tropical regions, where it enjoys high humidity levels. To replicate these conditions indoors, a short term solution is to mist your plant regularly, especially during the drier months of winter. You can also place your plant on a pebble tray filled with water. As the water evaporates, it will increase the humidity around the plant.

Longer term solutions include grouping with other high humidity plants and adding a humidifier.


The Stromanthe triostar prefers warm temperatures, ideally between 65 and 80 degrees Fahrenheit. Avoid placing your plant near drafts or cold windows, as these can damage the leaves. During the winter months, keep your plant away from heat vents, as dry air can cause leaf curling and browning.


Feed your Stromanthe triostar with a balanced liquid fertilizer diluted to half-strength once a month during the spring and summer. Avoid fertilizing during the fall and winter when the plant may be dormant.


Stromanthe Triostars should be repotted every year or two, or when they have outgrown their current pot. Choose a pot that is one size larger than the current pot and use a well-draining potting mix.

Pests and Diseases

Stromanthe Triostars are susceptible to a few pests and diseases, including spider mites, mealybugs, and fungal leaf spots. If you notice any pests or diseases, treat the plant immediately with an appropriate pesticide or fungicide.
