Guide
Written and kept by people who grow it. Every section carries its source.
Light, water and humidity
Bright, indirect light suits Triostar; direct sun can burn and fade the leaves, though an hour or two of early sun is fine. Keep the soil moist but not soggy, and expect to water about every week and a half. It thrives at 60-80% humidity and is sensitive to minerals in tap water.
