A tarp can be sufficient for covering hay, but its effectiveness depends on its quality and how well it is secured. High-quality tarps made from durable, waterproof materials like polyethylene or polypropylene provide good protection against rain, snow, and sunlight, helping to keep hay dry and preventing spoilage.
However, the tarp must be properly secured to prevent wind from displacing it, and it should be checked regularly for tears or damage that could compromise its ability to protect the hay. While generic tarps are relatively inexpensive, they may not be as breathable as specialized hay covers, and can create condensation issues if not properly ventilated.
