Moss/Lichen on evergreens
Posted by Terra Gordon on June 28, 2006
Q: I have several evergreens on my ocean side property that have moss or lichen hanging from them. It seem to start in the middle of the tree and work it's way out. The trees that are covered seem dead. Can I do anything to save the ones not far gone? Or do I have to let nature take it's coarse?
State: Nova Scotia
A: Sounds to me that the lichens or mosses are growing on trunk and branches that are shaded? If this is the case, these shaded areas retain more moisture and this provides a nice environment for them to grow. Although mosses or lichens grow on the bark they won't do any harm to the tree. In fact, I think they add to the beauty of any tree.
Most evergreens need lots of sun on their foilage or it dies back. This is why as many evergreen trees grow, the inner portions tend to die out where it is shaded, leaving just the outer areas green. If you're concerned about dieback in the inner areas, be sure to thin the outer areas so plenty of sunlight can get into the middle of the tree. Hope this helps. If I haven't been clear enough, please feel free to get back to me.
