Atrichum altecristatum is a terrestrial moss that grows best in cool, humid, shaded environments with consistently moist, acidic soil. It requires no fertilisation and is best suited to woodland terrariums, shade gardens, or moist rock features. Avoid direct sun and drought conditions, as this moss is sensitive to drying out.
