Exterior Wood Trim Mold Prevention

Bob asked 5 years ago

I live near Plainfield Illinois and my lot is wooded and near a pond. I am experiencing mold on my exterior wood trim, specifically the fascia, soffit, and crown molding. We have painted these with Benjamin Moore oil base primer and final coat. After about one year, we get significant black mold on these surfaces. Is there anything we can do to prevent this mold?
