What Your Custom Schedule Includes

Indoor Seed Starting Windows

Exact weeks to start slow-maturing nightshades (tomatoes, peppers) under grow lights so they are vigorously rooted without becoming root-bound.

Direct Sowing & Transplant Dates

Safe ground-contact dates for seed potatoes, dry beans, sweet corn, and storage carrots once your soil hits active germination temperature.

Fall Harvest & Hard Frost Cutoffs

Countdown dates for winter squash curing, late-season brassica planting, and autumn garlic planting before winter ground freeze.

Frequently Asked Questions

How is my frost date calculated?

We cross-reference your 5-digit ZIP code with regional weather station datasets covering 30-year historical climate normals. This isolates your 90% frost-free threshold rather than statewide averages.

What crops are included in the custom schedule?

Our schedule prioritizes calorie-dense and long-storing survival crops: Seed Potatoes, Dry Storage Bush Beans, Winter Squash, Paste Tomatoes, Storage Carrots, Sweet Corn, Hardneck Garlic, and Cold-Hardy Greens.

Is this tool really free?

Yes, 100%. We provide this free calculator to help families build self-reliance and plan food security. You can print, save, or bookmark your schedule anytime.
