  "description": "A quarter acre (about 10,890 square feet) is a common suburban lot size.

    {
      "q": "How much grass seed do I need for a 1/4 acre lawn?",
      "a": "At a typical new-lawn rate of 250 sqft coverage per pound, a quarter acre (10,890 sqft) needs about 44 pounds of seed."
    },
    {
      "q": "Does overseeding need less seed than a new lawn?",
      "a": "Yes, overseeding an existing lawn typically uses half the new-lawn rate, so increase the coverage-per-lb field to roughly 500 sqft per lb for overseeding jobs."
    },
    {
      "q": "Why does seed coverage vary by grass species?",
      "a": "Seed size differs dramatically between species — fine fescue seeds are much smaller than tall fescue or ryegrass, so always follow the specific product's label rate rather than a generic average."
