Orthotrichum typically grows on tree trunks and rocks, preferring well-drained yet moist environments. Basic care includes ensuring sufficient light but avoiding direct, intense sunlight. Orthotrichum thrives in temperate climates without extreme temperature fluctuations. Water needs are moderate, and overwatering should be avoided to prevent rot. Common challenges are overwatering, insufficient lighting, and infestations by pests like aphids. Seasonally, orthotrichum requires less water in winter but may need protection from frost, while spring and summer support active growth, needing more attention to moisture levels.
