Regional planting windows

Central NC · spring

Central NC: winter through spring, material-specific

Use the Central calendar only for a Central North Carolina garden

Central NC: late summer through fall, material-specific

Use the Eastern, Central or Western calendar that matches your location

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 chosen material matches the calendar entry.
  • The bed drains and can be kept weed-free while plants establish.
  • The variety and day length fit the local recommendation.

How to start onions

The planting material changes the schedule and harvest goal. Use the state calendar rather than one universal onion date.

Match the onions method

The planting material changes the schedule and harvest goal. Use the state calendar rather than one universal onion date.

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. Do not merge bulb and green-onion timing into one answer; they have different planting material and finish goals.
