How the date is calculated

More than simple date addition

The uploaded spreadsheet repeats plantings at a chosen interval and works backward from the fall frost date. This version also includes a crop-specific frost allowance and a fall slow-growth buffer.

1

Start with your fall frost date.Cold-hardy crops may continue beyond it; tender crops do not.

2

Subtract maturity time.The calculator uses the value for your chosen variety.

3

Allow for slower fall growth.Shorter days can delay maturity even before freezing weather.

Best crops for repeating

Focus on short harvest windows

Leaf lettuce, radishes, spinach, bush beans, beets, cucumbers, and sweet corn benefit most from repeated plantings. Tomatoes, peppers, eggplant, winter squash, melons, and onions usually occupy the garden for most of the season.

A calculated date is a planning estimate. Soil temperature, heat, rainfall, variety, latitude, and pest pressure can shift both maturity and harvest.
