Count a Whole Garden Back From Your Last Frost Date — Free
Enter the last frost date for your plot and everything that has to happen before it — sowing, ordering, hardening off — and the card files each job with the date it has to start. The free tier is the whole card: every field, every state, and the state link. Nothing is withheld behind the optional one-time tier.
1 · Set the seed card
FIRST-LOAD · sample record filed
Data note: Everything is computed in this browser tab. Nothing you type is uploaded, and nothing is stored on our servers. Redact names and identifying details before you paste anything sensitive, and check the output against the named source before you act on it.
2 · Read the filed card
GratisAI counted my garden back from the last frost date — every sowing, order and repair filed with the day it has to start.
Boundary: This does date arithmetic on the frost date and lead times you type in; it is not horticultural advice and it cannot know your soil, aspect or microclimate. Check sowing times against the seed packet and your own observations, and treat any frost date as an estimate rather than a guarantee.
Free core · $4 one-time
The on-screen result is free and repeatable forever. The one-time tier adds a tangible file you keep and the saved history that comes with it; it never removes or degrades the free result.
