Mood Moss is a fascinating species.
It’s affectionately named for its temperamental changes in appearance. When suitably watered it’ll look vibrant and full, but when dehydrated it can look kind of dull and lackluster.
A bit of a diva really, but nothing we can’t handle with some good care!
The clumpy nature of this moss makes it an excellent accent plant for terrariums. Plus, the textured windswept look is sure to really make your landscape pop.

Lighting
As with most mosses, Dicranum scoparium will do best with bright, indirect sunlight.
The brighter, the better, but be sure to keep it out of direct sunlight. That’s one surefire way to put it in a terrible mood… and you know, damage it irreparably.
If you’re in doubt, you should be able to read a book comfortably but not feel any warmth on your skin. North-facing windows tend to be a good bet.
Alternatively, you can always use grow lights to maximize light intensity without risk.
Watering
Mood Moss does best when it’s consistently moist but never wholly saturated.
So, as with Cushion Moss, I like to prepare Mood Moss by giving it a good bath first. Let it soak for a few minutes to thoroughly saturate itself, then squeeze out the excess water.
How this moss looks and feels now is the desired state when it’s planted up too.
To effectively maintain this in a terrarium, give it a light misting whenever it’s starting to look dry.
Substrate
Honestly, this isn’t particularly picky when it comes to where it grows.
It doesn’t have roots, after all.
Still, it does have root-like structures called “rhizoids” that it can use to anchor itself. So Mood Moss will happily grow on a range of terrarium substrates, as long as it can make contact properly.
A tropical terrarium mix should work a treat. Plenty of drainage to prevent it from becoming waterlogged and good water retention to help to maintain humidity in the container.
You can’t go too wrong with the classic ABG mix or any modern adaption of it.
Temperature & Humidity
Despite being a temperate moss, Dicranum scoparium will thrive in the warm, humid environment of a terrarium.
Room temperature and anything above 60% humidity should be fine, and it’s pretty forgiving on both fronts.
That being said, though the hardy nature of this moss means it’s accustomed to drying out a little, it’s not going to survive for long in an open container unless you’re regularly misting it.
Growth
As an acrocarpous moss, Mood Moss forms dense clumps. With the leaves growing upwards to give a wavy, fluffy appearance.
This gorgeous texture makes it a great choice for a moss terrarium.
It’s not a particularly quick grower and puts most of its energy into growing longer leaves rather than spreading out. Even then, it shouldn’t need much trimming.
The clumpy form gives it a lot of versatility. You’re to easily tear off chunks at the exact sizes that you need to place in different areas of your terrarium.
Propagation
Dicranum scoparium propagates through spores. They form in capsules at the ends of long stalks and are released to the wind to settle elsewhere – forming a new colony.
Though they won’t naturally get far in a terrarium with no airflow…
The easiest way to get meaningful propagation yourself is to divide it up and place it evenly amongst the space to maximize the spread.
Varieties & Similar Plants
Dicranum is a large genus of mosses that all form the typical densely packed clumps with wave-like leaves. Variations include; Dicranum fuscescens (Dusky Fork-Moss) and Dicranum bergeri (Waved Fork-Moss).
Cushion Moss (Leucobryum glaucum) is another condender for the best terrarium moss crown. It’s somewhat similar to Mood Moss, just with shorter leaves.

Frequently Asked Questions
Mood Moss does spread under the right conditions, but it’s a lot slower than sheet moss species when it comes to coverage. That’s why it’s more commonly used as an accent moss rather than a carpeting moss.
Mood Moss can grow several inches tall if given sufficient lighting and care.
