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.

  • Cold risk is past and the soil is warming.
  • The transplant is hardened off and not root-bound.
  • The selected variety fits the remaining heat or frost-free time.

Match the tomatoes method

Use a sturdy transplant after the weather and soil support warm-season growth. Separate spring and fall opportunities where the state source does.

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 put out flowering, stressed transplants just because the nominal first date has arrived.
