  "summary": "Bag count for mulching a bed using standard 2-cubic-foot bags.",
  "description": "For smaller garden beds, buying mulch by the bag from a home improvement store is often more convenient than arranging a bulk delivery, and standard mulch bags are sold in 2-cubic-foot units (with 1 and 3 cubic foot bags also common depending on brand). This calculator takes your bed area and spread depth, computes total cubic feet needed, divides by your bag size, and rounds up to a whole bag with a waste allowance for the mulch that misses the bed during spreading. Because bagged mulch costs meaningfully more per cubic foot than bulk delivery, the tool is most useful for beds under roughly 200-300 square feet where a bulk delivery minimum wouldn't be worth arranging, or for topping up an existing bed rather than a full fresh application. It also shows the total cubic feet and equivalent cubic yards so you can compare bagged pricing against a bulk quote before deciding which way to buy.",
  "formula": "Cubic Feet = Area × Depth(ft). Bags = ceil((Cubic Feet ÷ Bag Size) × (1 + Waste%)).",

    {
      "q": "How many bags of mulch do I need per 100 square feet?",
      "a": "At the standard 3-inch depth, about 13-14 bags of 2-cubic-foot mulch cover 100 square feet; at 2 inches, around 9 bags suffice."
    },
    {
      "q": "Is bagged mulch worse quality than bulk mulch?",
      "a": "Not necessarily — bagged mulch is often more consistently screened and aged, while bulk mulch quality varies more by supplier, though bulk is usually significantly cheaper per cubic foot for larger jobs."
    },
    {
      "q": "What's the difference between 1, 2, and 3 cubic foot bags?",
      "a": "They're simply different package sizes of the same coverage math; always check the bag's stated cubic footage rather than assuming a standard size, since it varies by brand and product line."
    },
    {
      "q": "Should I use a different waste factor for small beds?",
      "a": "Small, irregularly shaped beds often warrant a slightly higher waste factor since edging and working around plants leads to more spillage per square foot than a large open bed."
