A seasonal checklist and calendar

Turn your frost dates into a weekly garden plan

Choose a starting season, check planting and clearing windows, and turn your local frost dates into weekly tasks and a calendar.

1. Start with local dates and a real planting day

Have your local last spring frost, first fall frost and intended care-start date ready. Frost dates are estimates, so soil temperature, the forecast and the seed packet still decide when to plant.

No reliable dates yet? Choose Relative dates only inside a plan. You can still use the layout and before/after-frost windows; calendar export needs dated inputs.

2. Choose the season you want to work through

Start in spring

Separate lettuce and bean zones; add a first fall frost date to check the remaining season.

2027-04-01 to 2027-08-18

Includes planting, harvest checks and clearing. Review the dates after applying your own conditions.

Plant a fall crop

Work back from the first fall frost, with a maturity buffer for lettuce, spinach and radishes.

2027-07-01 to 2027-10-20

Includes planting, harvest checks and clearing. Review the dates after applying your own conditions.

Try a three-crop relay

Radishes, beans, then spinach. The example needs a long season: May 1 last frost to November 15 first frost.

3. Check the changeovers, then export

  1. Enter every frost date you intend to use, confirm the date basis and select Apply changes.
  2. Read From planting to clearing. If a crop has too little time, change the planting, use a faster suitable cultivar or drop a later phase.
  3. Download Calendar (.ics) for your adjusted dates, or print the full weekly checklist. The calendar contains planning windows, not weather alerts.
  4. Check off completed weeks and use the season journal to record actual planting, harvest and clearing. Save a JSON backup if you want to keep a separate copy.

See a dated example before you begin

This fall example starts on 2027-07-01 and uses 2027-10-15 as the first fall frost. These are sample dates, not a forecast for your location.

The weekly plan continues through cleanup. Before planting a successor, confirm that the previous crop has actually left the space.

Why these checks matter

Fall planting needs enough time before local frost, with different cold tolerance and maturity times for each crop. Minnesota’s regional dates are not used as your local dates here. Clearing the preceding crop is part of the changeover.
