|---|---|---|
GET /compost-cn-ratio | $0.02 | Carbon-to-nitrogen ratio of a compost mix by the Cornell formula, or the greens-to-browns amounts that reach a target ratio. |
GET /drip-irrigation | $0.02 | Drip irrigation math: gallons for inches of water over an area, emitter flow, supply limit and run time per watering. |
GET /fertilizer-rate | $0.02 | Fertilizer product needed for a nutrient target per 1000 sq ft from its N-P-K analysis, with the P and K delivered and bags. |
GET /frost-risk | $0.02 | Frost or freeze class of a forecast low against plant hardiness, plus where a date sits against your average frost dates. |
GET /growing-degree-days | $0.02 | Growing degree days from daily lows and highs with a base temperature and upper cutoff: daily and cumulative totals. |
GET /plant-spacing | $0.02 | Plants that fit a bed at a spacing (grid or offset rows) and seeds to sow from germination rate, per bed and per square foot. |
GET /planting-dates | $0.02 | Planting calendar from your frost date: dates for tasks given as weeks before or after, such as seeds indoors 6 weeks before. |
GET /soil-volume | $0.02 | Soil or mulch for a rectangular or round bed: cubic feet, yards, litres, bags, settling allowance and a mix split by parts. |

Garden calculators using standard formulas, published conventions (Cornell composting, NWS frost wording) and your inputs, provided as is. Plant response depends on variety, microclimate, soil and weather; frost thresholds and planting offsets are common guidance, not guarantees. Fertilizer and water amounts are starting points: follow product labels and local extension advice. Every paid response carries a disclaimer field.
