Your garden, by the season
Sezona tells you what to do in your garden and vegetable plot today — timed not by a generic planting calendar but by the climate of your own plot.

Questions
How do I find the last frost date for my garden?
Tell Sezona where your plot is. From the last 30 years of weather it works out when your last spring frost and first autumn frost usually are, how long your growing season is and how much warmth the summer brings.
When should I start seeds indoors?
Seed starting is counted back from planting out, and planting out from your plot's last spring frost. Sezona does this for every crop and reminds you when it's time to sow.
Do I need an account?
No. Your plot, plantings and notes are kept on your phone, encrypted. Nothing goes to the server without your consent.
How much does it cost?
The app is free. The full plant catalog on the server and the project's AI come with a subscription; the first 30 days are free. You can also connect the AI helper with your own key.
