  "summary": "A 200 sq ft bed at 3 inches deep needs about 17 standard 2 cu ft bags of mulch.",
  "description": "Mulch is sold by volume, so the amount you need is bed area times desired depth converted to cubic feet, then divided by the bag size. This calculator converts your garden bed's square footage and target mulch depth into cubic feet and yards, then tells you how many standard 2 cubic foot bags (or how many bulk yards) to order.",
  "formula": "Volume (cu ft) = Area × (Depth in inches ÷ 12). Bags = Volume ÷ Bag Size. Cubic Yards = Volume ÷ 27.",

    {
      "q": "How many bags of mulch do I need?",
      "a": "For a 200 sq ft bed at 3 inches deep, you need 50 cubic feet of mulch, which is about 25 standard 2-cubic-foot bags, or roughly 1.85 cubic yards if buying in bulk."
    },
    {
      "q": "How deep should mulch be?",
      "a": "2-4 inches is standard; more than 4 inches can smother roots and encourage rot against tree trunks and stems."
    },
    {
      "q": "Is bulk or bagged mulch cheaper?",
      "a": "Bulk delivery is almost always cheaper per cubic yard once you need more than about 2-3 cubic yards (roughly 27-40 bags), since bagged mulch carries a packaging and retail markup."
    },
    {
      "q": "Does bed shape matter?",
      "a": "No — only total area and depth matter for volume; irregular shapes just need their square footage measured in sections and summed before entering it here."
