Field notes
The planner exposes its timing logic: plant-out dates are based on crop offsets from the frost date, indoor sowing subtracts the indoor-growing period, and direct-sow timing follows cited guidance. A ±1-week control lets users see how a later or earlier average frost date changes the schedule. The site cautions that frost dates are long-term averages and recommends local extension advice and checking the 10-day forecast before planting tender crops.
