Where is the water coming from?
That's a given. Is it run off from a neighboring property? Can you share a photo? Trying to determine if you need to regrade the area, add drains, etc.
Many people put a narrow gravel area under the fence line
Thank you so much Laura
DIg a small space and put gravel below the fence. Then, seal the bottom of the fence with a product like this: https://amzn.to/2WaTw3o
Thank you Jeremy. I'm having a landscaper take a look.
I will talk with him about your suggestion.
You can add some river rock or larger rock along edge. I have large (potato sized) and larger round rock.
Thank you very much. I am looking into this.
