Planting calendar

A month-by-month view for tropical, frost-free, and frost climates, including small spaces and containers. Empty cells mean the data is not sourced yet.

Methodology

How does this planting calendar decide a month?
It only marks a month when a planting-window row exists for that crop and climate zone. An empty month means the window is not stored. It is not a suggestion to skip or to sow.
Why are so many crops marked no data?
A crop shows months only when a planting window for that climate is stored. Those rows can still be unverified: the page names the source and asks you to confirm them. Data coming soon means no window is stored for that crop and climate.
How are tropical wet and dry seasons handled?
Tropical and frost-free regimes use month windows. Named season ranges are drawn separately and are not collapsed into one wet-season pair. They are climate context, not planting instructions.
What happens in a frost climate?
Temperate and continental regimes use day offsets from a sourced last or first frost date. If those dates are missing, the page says insufficient frost data and does not convert offsets or month numbers into a calendar.
What if my location is not in the list?
You can pick a climate regime yourself. That choice is labelled manual. It is not a sourced location, and it still will not invent planting months.
