The answer to 'how to care for fence' is to regularly inspect, clean, and maintain your fence to keep it looking its best and lasting for years. This includes tasks like washing the fence, tightening any loose boards or posts, and repainting or restaining the wood as needed.
Start by visually inspecting your fence every few months, looking for any signs of damage, wear, or deterioration. Check for loose boards, protruding nails, and cracked or peeling paint or stain. Clean the fence using a mild detergent and water, scrubbing away any dirt, mildew, or debris. For wooden fences, you may need to sand and refinish every few years to protect the wood from the elements.
