The calendar is the first filter

Plant only when the crop is ready

A range can be correct for the region and still be unsuitable for today. Check the crop and the garden before committing seed or plants.

  • The garden can support steady leaf growth after establishment.
  • Young plants can be watered through warm periods.
  • The intended harvest size fits the remaining season.

Make the weather decision

A published window is a planning range. Wait when soil condition, moisture, heat or cold makes establishment unsafe.

When the simple answer breaks

Early and late decisions

The useful answer is an action when weather or the remaining season no longer fits the headline range.

The season is early

Use the protective edge of the range

Planting at the first possible date is reasonable only when the crop and forecast support it; a calendar is not a command.

The season is late

Count maturity before committing

Check the variety’s days to harvest and leave a margin for establishment. Decide whether you want young leaves or full plants; the practical late edge is not the same.
