Moss on Fruit Trees

Q: I have a pear, apple and plum tree on the property I am renting. They have a lot of moss all over them. is this common (we have wet winters) or should I look into spraying? Any ideas?

Hardiness Zone: 8a

A: Kelly,

Moss and lichens growing on your trees in the Pacific Northwest is not uncommon. They aren't usually harmful to trees, unless of course they become to too heavy-making the braches susceptible to wind damage. Most moss grows on older trees in conditions where the sunlight is diffused. One way to decrease its potential for growth is to allow for more direct sunlight around your fruit trees and pruning to create better air circulation. In regards to removing the moss, don't spray or you may damage the tree. The best way to remove it is also the most labor intensive-by hand. Care needs to be taken not to harm any active growth or new buds, so this is best done in the winter months when the tree is in a dormant state. An alternative to removal by hand is to spray the moss off of the trees with a power washer. This should also be done during the tree's dormant period to prevent damage from the high water pressure. This method isn't suitable to more delicate trees. Hope this helps!
