Why does moss grow on fallen trees?
Here in Santa Barbara, California, the sun is not directly overhead, but to the south, so the south side of any object will get more sunlight than the north. This is why moss likes the north side of trees. The fuzzy texture and shade-loving characteristics of moss are in part due to it being a non-vascular plant.
What kind of moss grows on dead trees?
So, a lichen will not harm a tree. However, lichens—like Spanish moss—often appear in greater numbers on a tree that’s dying since the loss of leaves leads to a greater amount of sunlight on the bark. If you notice a greater number of lichens, contact one of our certified arborists in Austin, Texas, for a consultation.
Is moss growing on tree trunks bad?
Algae, moss and lichens aren’t harmful to trees, so don’t fret if you spot any of their green growth. They’re all-natural organisms, that are not actually fungi, that crop up on trees and lots of other plants.
Does moss only grow on dead trees?
The myth that moss only grows on the north side of trees likely originated as a way to help people navigate in a forest, letting the mossy trees serve as a natural compass. But if you let that myth serve as a map through the woods, you’re likely to get lost. That’s because in reality, moss can grow just about anywhere.
What is the relationship between moss and trees?
Types. Spanish moss is a type of epiphyte, a plant that lives on another. Epiphytes are distinct from parasitic plants in that they make their own food, so they do not harm the host tree; the host tree neither gains nor loses by their presence. Ecologists call this kind of relationship commensalism.

What does green moss on trees mean?
Those green-blue growths that you see on tree trunks and branches are not mosses. They are lichens. Lichens are not killing your tree, nor are they causing it to fail. They are telling you something about your tree’s health, though. Together, they provide the sustenance that enables the lichen to exist.
Why does Spanish moss grow on oak trees?
They withstand floods, hurricanes, and salt spray. They even tend to survive fires, because fire rarely reaches the crown, allowing the tree to re-sprout vigorously from the roots. This longevity makes live oaks the perfect spot for large growths of epiphytes such as Spanish moss ((Tillandsia usneoides).
Does lichen mean my tree is dying?
If your tree has had a sudden loss of leaves or a branch, it creates favorable conditions for lichen to grow. So while lichen is in no way harming your tree, its presence may point to an unhealthy or dying tree (caused by other reasons, such as pests, disease, or improper watering practices).
Why would Moss be better than grass?

Since moss spreads heavily on the branches and trunk of your tree, this could disguise and hide potential signs of disease and death.
Is Moss harmful to trees?

Does moss or lichen harm trees?
Mosses and lichens generally do not directly harm trees or shrubs. Lichens contribute to soil formation and provide food for animals. According to the Oregon State University Department of Biology, mosses and lichens can look attractive on some trees and shrubs.
