树干上长了一些苔藓，需要处理吗？

不知道是不是因为最近潮湿，几棵巴西牡丹树干上都长出了苔藓，一小片一小片绿色的，需要喷药处理吗？

要吧，感觉会吸干树木的水分，像老年斑

今年感觉虫灾什么的特别多。邻居的树墙长了好多虫，他们也是折腾了好久。

我查了一下网。Lichen on tree trunk. (Photo by Nick Polanin.) Lichens are often found on tree trunks, branches and twigs as the bark provides a stable place to reside to collect needed sunlight, rainwater and materials from the air. They grow on healthy trees, as well as stressed or otherwise unhealthy ones.

Some people believe that lichens that grow on trees are killing the trees. While there is still much to be learnt about the interactions between trees and lichens a century of investigation has produced no evidence to show lichens to be a major problem on trees.

They do NOT kill trees. ... Dying trees with fewer leaves to shade their branches provides lots of that. Something is killing your trees, but the culprit isn't lichens. So stop hating on lichens.

Algae, lichens and moss are non-parasitic plant-like organisms that colonise bark, rock and other hard surfaces. Lichens and algae are often mistaken for a fungal disease but, fortunately, they do not harm plants on which they grow.


Copper-sulfate sprayed on lichens on trees will kill the fungus side of the organism. Only use copper-sulfate as a treatment for tree lichen in late spring through early fall. It will not be effective in cool weather. You can also remove tree lichen with lime sulfur.May 8, 2018

看起来没有大碍，可以放心了。

这种无害的，不喜欢的话搽掉就行，我见园丁直接用手搽了，第二年又长出来。

這是地衣，空氣好的地方才能見到，只是依附在有遮蔭的粗糙表面生長(石頭跟屋頂上也常見)，是真菌和綠藻的共生體，吸收霧氣中的水份光合作用自給自足，不是寄生。

地衣不會對樹的生長造成不良影響，頂多就是看起來斑駁有人不喜歡，我個人是挺喜歡的，畢竟是環境好的一個指標。
