Dicranum scoparium Moss in Terrariums
Moss Name: Dicranum scoparium Moss
Common Names: Mood Moss, Broom Moss
Moss Type: Dicranum scoparium, commonly called broom moss or mood moss, is an acrocarpous moss: it grows upright in dense, rounded cushions and mounds rather than spreading in flat mats. Its narrow leaves curve to one side like the bristles of a broom, which is how it earned its common name.
Dicranum scoparium, more commonly known as broom moss, is a small perennial plant that is native to Europe and Asia. Broom moss is often used as an ornamental plant in terrariums and fairy gardens due to its delicate appearance.
Broom moss grows across cool, damp habitats throughout the Northern Hemisphere, forming deep green tufts on soil, rocks and rotting logs on shaded forest floors. Like all mosses it has no true roots or flowers; it anchors with fine rhizoids, absorbs moisture through its leaves, and reproduces by spores released from slender capsules.
Growing Dicranum scoparium Moss in Terrariums
Broom moss forms neat, rounded mounds and isn't especially demanding, but it does prefer humid conditions and partial shade. If a terrarium runs too dry or too bright the moss can brown and dry back; kept cool and consistently moist, it makes a striking, sculptural centrepiece in a miniature landscape.
Ideal Conditions for Dicranum scoparium Moss in Terrariums
Lighting: Although Dicranum scoparium can tolerate some sun exposure, it grows best in shady conditions.
Growing Medium: Broom moss typically grows in moist, shady areas such as woods or forest floors. It prefers acidic soil with a pH level between 5.0 and 6.5. However, it can also grow in alkaline soils with a pH level up to 8.0.
Temperature: While D. scoparium can tolerate a wide range of temperatures, it prefers cooler conditions and will go dormant in temperatures above 20 degrees Celsius (68 degrees Fahrenheit). Because of its relatively low temperature requirements, this moss is often used in terrariums and other environments where maintaining high humidity levels is important.
Watering: One of the key things to remember when caring for broom moss is that it has very specific watering requirements. The plant prefers to be kept moist at all times, but not soggy. To achieve this, water your broom moss once or twice a week, depending on the weather and humidity levels. It’s also important to mist the plant regularly, as this will help to keep its delicate leaves hydrated.
Humidity: Dicranum scoparium thrives in moist environments and is often found growing on forest floors, in caves, and on damp rocks. In the wild, this moss prefers shady locations with high humidity levels. However, it can also adapt to growing in full sun if the air is sufficiently moist. When grown indoors, Dicranum scoparium requires similar conditions to those found in its natural habitat.
Caring for it: like all terrarium moss, Dicranum scoparium wants high humidity, bright indirect light, gentle airflow and consistently moist, never waterlogged, conditions. For the full method see our guide to caring for moss in terrariums.
