Moss Growth on my Trees


I had sent this question a few months ago and had no response so thought I would resend. Can you tell me if the moss growth on my tree will kill it. I live on the lake and theres always a lot of dew that last until noon


Hello thank you for contacting the Toronto Master Gardeners again.

Moss on trees has no negative impact on your trees, and definitely will not kill your trees.

Sometimes the presence of moss can indicate  that a tree may already be stressed, but not necessarily. Often moss exists where there is somewhat excessive moisture in a shady condition, but other variables can be involved.

Improving air circulation and reducing residual moisture can help deter moss.

If your trees that the moss is on do not look that robust, I would evaluate the environment to ensure that there is sufficient light and soil condition is optimal.
