SEEDS & SCHEDULING / PLAN YOUR ROUNDS
Succession Planting Planner
Turn your first sowing date, preferred spacing between rounds, and planting window into a practical date-by-date schedule. You choose the timing; the calculator handles the calendar.
01 / YOUR PLANTING PLAN
Set the schedule
Use planting dates and intervals that fit your crop and growing conditions.
02 / PLANNED DATES
Your planting calendar
Dates are calculated only from your entries, not weather or growing predictions.
Build your schedule to see each planting round.
Dates do not verify frost risk, soil temperature, crop maturity, or whether your bed is ready for replanting.
YOUR CALENDAR
Planting dates at a glance
View dates by month, then use the full table to copy individual rounds into your calendar.

* “Bed ready by” appears only when you provide expected occupancy days; it is your assumption, not a measured harvest date.
THE METHOD
How the succession dates are calculated
Repeat dates
Every round equals the first date plus a whole number of your chosen intervals. Four rounds from April 1 at 14-day intervals fall on April 1, April 15, April 29 and May 13.
Stop on a date
With an end-date limit, the planner keeps only planting dates on or before that date. If you choose a number of rounds, it generates exactly that many, up to 52.
Check shared-bed overlap
When your estimated occupancy lasts longer than the interval, successive rounds could compete for the same bed. Use different sections or revise the schedule if necessary.
Round date = First planting date + (round number − 1) × interval daysOne week equals seven calendar days. Every date is calculated without timezone shifts.
READ BEFORE PLANTING
A date plan is not a growing guarantee
The planner does not know your last frost, heat waves, rainfall or daylight. Revisit dates using local forecasts, extension advice and the seed packet.
Not every crop benefits from repeated sowings at the same interval. Some crops produce over a long season, while others are more suitable for several smaller batches.
The optional occupancy field is an estimate. Harvest, cleanup and preparation can push real turnover later than the calculated date.
