Hey there, fellow garden enthusiasts! I’ve been getting lots of questions about moss growth during winter, and today I’m gonna share everything you need to know about these fascinating little plants that stay green when everything else goes dormant.
The Quick Answer
Yes, moss does grow in winter! Unlike most plants that go completely dormant, moss can remain active and continue growing even in freezing temperatures. While growth slows down, most moss species stay green and can photosynthesize year-round when conditions allow.
How Moss Survives Winter
The Secret Superpower: Poikilohydry
One of the coolest things about moss is something called poikilohydry. I know, big word right? But it’s actually pretty simple – it means moss can:
- Go dormant when conditions aren’t great
- Lose almost all its water without dying
- “Wake up” and start growing again when water returns
- Survive temperatures below 40°F while staying green
Winter Growth Conditions
For moss to keep growing in winter it needs
- Access to light (even filtered light through snow works!)
- Adequate moisture from rain, snow, or humidity
- Protection from harsh winds
- Some exposure to avoid complete burial under snow
Different Types of Winter Moss
Here are some common moss varieties that handle winter like champs:
- Sheet Moss (Hypnum)
- Easy to transplant
- Great for ground cover
- Handles winter well
- Hair Cap Moss (Polytrichum commune)
- Tolerates full sun
- Excellent for erosion control
- Strong winter survivor
- Rock Cap Moss (Dicranum)
- Perfect for deep shade
- Loves growing on rocks
- Stays green all winter
- Cushion Moss (Leucobryum glaucum)
- Forms attractive mounds
- Hardy winter performer
- Maintains shape under snow
Winter Care Tips for Your Moss Garden
If you’re growing moss, here’s how to help it thrive during winter:
Do’s:
- Let snow partially cover moss (it acts as insulation)
- Maintain light moisture levels
- Clear heavy debris like fallen leaves
- Allow proper ventilation
Don’ts:
- Don’t remove snow completely
- Avoid walking on frozen moss
- Don’t use ice melt products nearby
- Don’t fertilize during winter
Why Growing Moss in Winter is Awesome
We love growing moss in winter because:
- It stays green when other plants are brown
- Requires minimal maintenance
- Creates beautiful winter landscapes
- Provides erosion control year-round
- Doesn’t need mowing or fertilizing
Winter Moss Problems and Solutions
Sometimes you might run into these issues
| Problem | Solution |
|---|---|
| Ice buildup | Gently brush off heavy ice |
| Dry patches | Light misting during warmer days |
| Snow compression | Create paths around moss areas |
| Winter burn | Provide wind protection |
Final Thoughts
I gotta say, moss is pretty amazing in how it handles winter. While other plants are taking their winter nap, moss just keeps on trucking, even if it’s moving a bit slower. At our garden center, we’ve seen moss patches stay vibrant through some pretty brutal winters!
If you’re thinking about adding moss to your winter garden, go for it! It’s one of those low-maintenance plants that’ll reward you with year-round green without much fuss. Just remember to give it some basic care, and it’ll be happy as can be, even when Jack Frost comes knocking.

Notes from a plant nerd: Winter moss gathers no stones
Among my favorite types of plants that grow year-round, and tend to especially shine in the wintertime, are mosses.
Mosses are incredibly beautiful and incredibly diverse members of the plant kingdom that tend to get a short shrift from people who either don’t notice them at all or think that they only indicate a problem. And that is too bad, for while they certainly are short, they are also beautiful and as deserving of study and attention as any tree or wildflower.
Mosses are non-vascular plants, which means that unlike flowering plants, shrubs and trees, mosses and other non-vascular plants like liverworts, hornworts and algae do not have specialized cells that can be used to carry water and mineral nutrients upwards into plant tissues and can’t transport sugar and carbohydrates down into the roots. In fact, mosses don’t even have roots that grow into the soil, wood or rocks that they grow on. Rather, mosses attach themselves to their growing medium by way of small, thin, root-like structures called rhizoids that produce acids and glues that help them stick to the growing surface.
Mosses also differ from other plants in their reproductive method. They don’t produce flowers, pollen, seeds or fruits but rather reproduce by spores, similar to ferns and mushrooms, and rely mostly on the wind to disperse and spread the spores. The spores are produced in a structure called a sporophyte that sticks up above the moss leaves and aids in dispersal by being higher than the surrounding moss to help catch the wind upon release. Mosses can also increase their spread and grow into new locations when pieces of moss dislodge, or fragment, from the colony and find a new home to begin growing.
Studying mosses and learning their names and how to differentiate the different species is a challenging skill that involves the use of magnifiers like jeweler’s loupes, and microscopes. You can learn a lot about different mosses through a few different resources like books, workshops and websites. One of the best resources in the world for learning moss just happens to be the local expert Annie Martin of Mountain Moss Enterprises based in Brevard. Mossin’ Annie, as she is known, is the author of “The Magical World of Moss Gardening” the seminal book on moss gardening and propagation. She also maintains a great website, mountainmoss.com, that can be used to help identify mosses, and you can even purchase mosses there to use in your own garden or moss lawn creations.
And speaking of moss lawns, another friend I have in the moss world is Paul Moore, aka “The Moss Man” who has a beautiful and low-maintenance moss lawn at his home outside of Nashville, Tennessee. This lawn is green and growing all year-round and is a great eco-friendly replacement for a traditional grass lawn. Moss lawns require no fertilizing, and the minimal maintenance includes hand-pulling small weeds, removing leaves in the fall, and the occasional watering in dry times if you want to “green” it back up. Paul’s moss lawn is so beautiful, it has been featured in Southern Living, among other publications.

FAQ
Can moss grow in winter?
Winter can be a challenging time for gardeners, with most plants dormant and the ground covered in snow. But did you know that moss is a true evergreen, able to thrive and grow even in the coldest months? The wonderful thing about moss is that it can be planted year-round nearly everywhere.
Can moss grow year-round?
The wonderful thing about moss is that it can be planted year-round nearly everywhere. Unlike traditional plants that require specific soil conditions and climates, moss is adaptable and can thrive in a variety of environments. One of the reasons moss is able to survive in the winter is through a process called poikilohydry.
Why is moss green all winter?
Despite being dormant, moss will remain green all winter, waiting for the thaw to come out of dormancy. During the winter, moss is protected and happy under the snow, and when the snow melts, the moss quickly comes out of dormancy. This allows moss to survive in conditions that would kill other plants.
Do mosses survive winter?
Not all winter mosses cope the same. Species adapted to prolonged snow cover can perish if ice coats their tissues, blocking gas exchange. Conversely, mosses like Andreaea rupestris thrive on exposed rock and mountain peaks. Growth halts in late fall as icy crusts envelop the moss.
Can Moss survive in a dormant state?
This means that moss is able to survive in a dormant state when temperatures drop below 40 degrees. Despite being dormant, moss will remain green all winter, waiting for the thaw to come out of dormancy. During the winter, moss is protected and happy under the snow, and when the snow melts, the moss quickly comes out of dormancy.
Does Moss thaw in winter?
Despite being dormant, moss will remain green all winter, waiting for the thaw to come out of dormancy. During the winter, moss is protected and happy under the snow, and when the snow melts, the moss quickly comes out of dormancy.
